How to Use Arize Phoenix with Ollama

A Practical Guide for LLM‑Ops Engineers and Data Scientists

---

1. Introduction

Arize Phoenix is an open‑source observability platform that lets teams monitor, debug, and evaluate large‑language‑model (LLM) applications. It can record traces, run automatic evaluations, and surface visual insights that help you spot drift, bias, or performance regressions.

Ollama is a local, lightweight LLM host that exposes an OpenAI‑compatible API. By running Ollama locally, you can keep your data in‑house, cut inference costs, and experiment quickly.

Combining Phoenix with Ollama gives you:

Feature	Phoenix	Ollama
Trace collection	OTLP‑compatible	Any SDK that speaks OpenAI API
Model evaluation	Pre‑built templates (relevance, faithfulness, toxicity, etc.)	Directly feed your local model
Visualization	Embedding heatmaps, trace graphs, metrics dashboards	Immediate feedback on local prompts
Cost	Free, open source	Zero cloud‑usage costs

---

2. What Is Arize Phoenix?

Phoenix is built on top of OpenTelemetry (OTLP) and provides:

• Trace ingestion – collect request‑response pairs from any framework (LangChain, LlamaIndex, DSPy, etc.).
• Automatic evaluation – run your LLM output against a prompt or reference set using a library of templates (faithfulness, toxicity, coherence, etc.).
• Embeddings visualizer – cluster analysis and dimensionality reduction of user queries or knowledge‑base documents.
• Dashboards – metrics such as latency, error rates, accuracy, and drift alerts.

Phoenix is intentionally “playground‑first”: you can spin up a local UI and test everything before deploying to production.

---

3. Why Combine Phoenix with Ollama?

Pain Point	Why Phoenix Helps	Why Ollama Helps
Latency	Visualize and compare latency distributions across models	Run inference locally, no network round‑trip
Data privacy	Store traces locally, no third‑party transmission	Keep data on‑premises
Cost	Free tooling	Zero cloud inference cost
Rapid iteration	Playground allows instant parameter tweaks	Quick local inference without API throttling

---

4. Prerequisites

1. Python 3.10+ (recommended in a virtual environment).
2. Docker (optional, for running Phoenix locally).
3. Ollama installed locally – see https://ollama.ai/.
4. An OpenAI‑compatible API key if you want to evaluate against external reference data (optional).

---

5. Installing Phoenix

Phoenix can be installed as a Python package or run in a Docker container.
The Python route is easiest for experimentation:

python -m venv venv
source venv/bin/activate
pip install "arize-phoenix[evals,llama-index]"  # pulls in core, evals, and LlamaIndex integration

Alternatively, run the prebuilt Docker image:

docker run -d -p 5000:5000 arize/phoenix

Once the container is running, open the UI at http://localhost:5000.

---

6. Configuring Phoenix to Use Ollama

Phoenix treats any OpenAI‑compatible endpoint as a “provider.”
Ollama exposes an OpenAI‑compatible endpoint at http://localhost:11434/v1.

6.1 Set Environment Variables

export OPENAI_BASE_URL=http://localhost:11434/v1
export OPENAI_API_KEY=YOUR_LOCAL_KEY  # could be anything, Phoenix ignores it for Ollama

6.2 Create a Prompt Playground Session

1. In the Phoenix UI, click Playground → New Session.
2. Under AI Provider, select Custom.
3. Enter the base URL and API key above.
4. Choose a model from the list (e.g., llama3.1:8b).

You can now send prompts directly to your local Ollama instance from the Phoenix UI and immediately see the trace, latency, and evaluation results.

---

7. Sending Traces from Your Own Code

Phoenix provides a lightweight callback handler that you can plug into frameworks like LlamaIndex or LangChain.

from llama_index.callbacks.arize_phoenix import ArizePhoenixCallbackHandler
from llama_index.llms import OpenAI
from llama_index import VectorStoreIndex, PromptTemplate

# Tell LlamaIndex to use the Phoenix callback
callback_handler = ArizePhoenixCallbackHandler()

llm = OpenAI(
    model="llama3.1:8b",
    api_base="http://localhost:11434/v1",
    callbacks=[callback_handler]
)

index = VectorStoreIndex(...)  # build your RAG index

query = "Explain the benefits of using local LLMs."
response = index.as_query_engine().query(query)
print(response)

All requests will be automatically sent to Phoenix via OTLP.
You’ll see each trace appear in the Traces tab, complete with timestamps, request/response payloads, and any evaluation metrics you have configured.

---

8. Evaluating Responses with Phoenix

Phoenix ships with a rich library of evaluation templates, e.g., RAG_RELEVANCY_PROMPT_TEMPLATE. You can also write your own.

8.1 Using a Built‑In Template

from arize_phoenix.evals import RAG_RELEVANCY_PROMPT_TEMPLATE, OpenAIModel
from arize_phoenix import evaluate

# Assume `model_output` and `ground_truth` are strings
metrics = evaluate(
    model_output=model_output,
    ground_truth=ground_truth,
    eval_template=RAG_RELEVANCY_PROMPT_TEMPLATE,
    model=OpenAIModel(
        name="llama3.1:8b",
        base_url="http://localhost:11434/v1"
    )
)
print(metrics)  # {'relevance': 0.87, 'faithfulness': 0.92, ...}

The metrics are automatically logged to Phoenix, where you can compare them across runs.

8.2 Custom Evaluation Prompts

Create a prompt that asks the LLM to score its own answer:

CUSTOM_PROMPT = """
You are evaluating the following answer to a user query:
Q: {query}
A: {answer}
Rate the answer on a scale of 0–10 for relevance and factual accuracy.
Return a JSON object: {{"relevance": int, "accuracy": int}}
"""

metrics = evaluate(
    model_output=answer,
    ground_truth=None,  # self‑evaluation
    eval_template=CUSTOM_PROMPT,
    model=OpenAIModel(...),
)

---

9. Visualizing Embeddings

Phoenix’ Embedding Visualizer helps you understand how your data is clustered.

1. Load your query or document embeddings (e.g., via openai.embeddings.create).
2. Push them to Phoenix using the SDK:

from arize_phoenix import embeddings

embeddings.upload(
    vectors=vectors,          # list of embedding vectors
    labels=labels,            # optional metadata (e.g., topic)
    dataset_name="my_docs"
)

3. In the UI, open Embeddings → Dataset → my_docs.
   You’ll see a 2‑D/3‑D scatter plot, cluster boundaries, and the ability to filter by label.
   Use this to spot outliers or verify that your RAG knowledge base covers the query space.

---

10. Advanced Use Cases

Scenario	How Phoenix Helps	Tips
RAG system debugging	Trace each retrieval step, compare retrieved docs to ground truth	Use LlamaIndex + Phoenix callbacks to see which docs were fetched
Bias & fairness monitoring	Run periodic evaluation with labeled prompts	Store evaluation metrics in Phoenix, alert on drift
Latency SLA enforcement	Continuous latency dashboards, threshold alerts	Set up an external alerting rule (e.g., PagerDuty) via Phoenix webhook
Multi‑model comparison	Store traces for several Ollama models	Use the Model Comparison view to see accuracy vs latency

---

11. Troubleshooting Common Issues

Symptom	Likely Cause	Fix
Traces don’t appear	Phoenix OTLP endpoint unreachable	Verify Docker port mapping (-p 5000:5000) or local address (http://localhost:5000).
Model requests fail	Wrong OPENAI_BASE_URL	Ensure it points to Ollama’s v1 endpoint (http://localhost:11434/v1).
Evaluation metrics missing	Evaluation template not registered	Pass the correct eval_template and ensure OpenAIModel has a proper name and base_url.
Embedding upload errors	Mismatch vector dimension	Ollama’s embeddings (e.g., 768) must match the dataset schema.

---

12. Summary

Arize Phoenix turns a local Ollama deployment into a production‑grade LLM observability platform. By simply pointing Phoenix at the Ollama endpoint and enabling the built‑in callback handlers, you gain:

• Instant trace visualization
• Automated evaluation with a library of templates
• Embedding insights for data coverage and drift detection
• Dashboards that surface latency, accuracy, and error rates

Because both tools are open source, you can keep all data on‑premise and avoid costly cloud usage while still enjoying the benefits of a modern observability stack.

Happy building! 🚀

Harnessing Intel N150 Mini‑PCs as Homelab Powerhouses

Super‑powers for automation, AI, and a green‑friendly power bill

---

1. The Mini‑PC Revolution

When you think of a homelab, the first image that comes to mind is a row of towering servers humming in a data‑center‑style closet. The reality for the everyday hobbyist or home automation enthusiast is a far more intimate, energy‑efficient, and inexpensive solution: the Intel N150 mini‑PC.

The N150, part of Intel’s low‑power “Celeron” family, packs a 10th‑gen Intel® Pentium Silver J5005 processor, 8 GB of DDR4 RAM, and a 256 GB SSD into a compact 5 × 5 × 1.7‑inch chassis. Despite its modest specs, it offers:

• Full‑featured Linux support (Ubuntu, Debian, Fedora, etc.)
• PCIe‑like expansion via Mini‑PCIe for NVMe SSDs or Wi‑Fi adapters
• Dual‑channel DDR4 for smooth multitasking
• Thunderbolt‑compatible USB‑C for future‑proof connectivity

Because of its small form factor, the N150 runs on a single 5 V USB‑C power supply, drawing only ~30 W at peak load—roughly a third of what a typical home server consumes.

---

2. Why an N150 for Homelab?

Criterion	N150	Traditional Rack‑Server
Initial Cost	<$200 (includes a 256 GB SSD)	$1,500–$5,000+
Power Draw	~30 W	200–400 W
Noise	Quiet fan, ~35 dB	Loud chassis fans
Footprint	3‑inch depth	1U/2U space
Ease of Use	Plug‑and‑play, minimal maintenance	Requires skilled sysadmin
Flexibility	Virtual machines, containers, AI workloads	Enterprise‑grade but rigid

The key advantage is scalability on a budget. You can start with a single N150, add more as you grow, and keep the energy bill in check—perfect for hobbyists and prosumers alike.

---

3. Setting Up Your N150 Homelab

3.1. First Boot & OS Selection

1. Download an OS – Ubuntu Server 22.04 LTS is a solid starting point, offering long‑term support and a vast package ecosystem.
2. Create a bootable USB – Use Rufus (Windows) or dd (Linux/macOS).
3. Install – Boot the N150 from USB, follow the guided installer, and set a static IP via the DHCP reservation on your router.

Tip: Disable the default SSH login for the root user and create a dedicated user with sudo privileges.

3.2. Harden the System

• Firewall: Enable UFW (sudo ufw enable) and open only essential ports (22 for SSH, 80/443 for web services, 8123 for Home Assistant).
• Updates: Set unattended-upgrades to keep the system patched.
• Fail2Ban: Install to protect against brute‑force attacks.

3.3. Storage & Backup

Upgrade the internal 256 GB SSD to a larger NVMe SSD (up to 2 TB) if you plan to run database workloads. Use rsync or BorgBackup to mirror critical data to an external USB drive or a cloud bucket.

---

4. Virtualization: One Host, Many Worlds

With KVM (Kernel-based Virtual Machine) you can run multiple isolated virtual machines (VMs) on a single N150.

sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virtinst

Create a network bridge for VMs to access your LAN:

sudo nano /etc/netplan/01-bridge.yaml

Add:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0: {}
  bridges:
    br0:
      interfaces: [eth0]
      dhcp4: true

Reboot and launch a VM:

virt-install \
  --name ubuntu-22.04 \
  --ram 2048 \
  --vcpus 2 \
  --disk path=/var/lib/libvirt/images/ubuntu-22.04.img,size=20 \
  --os-type linux \
  --os-variant ubuntu22.04 \
  --network bridge=br0 \
  --graphics none \
  --console pty,target_type=serial \
  --location 'http://archive.ubuntu.com/ubuntu/dists/jammy/main/installer-amd64/' \
  --extra-args 'console=ttyS0,115200n8 serial'

Why virtualization?

• Isolation: Keep your AI service separate from your media server.
• Snapshots: Take a snapshot before a risky update.
• Consolidation: Reduce the number of physical devices you need to maintain.

---

5. Containerization & Automation

Docker is the lightweight alternative to full VMs. Install Docker:

sudo apt install docker.io
sudo usermod -aG docker $USER

Deploy a Home Assistant container for home automation:

docker run -d \
  --name homeassistant \
  -v /opt/homeassistant/config:/config \
  --restart=unless-stopped \
  --network=host \
  ghcr.io/home-assistant/home-assistant:stable

Use Docker Compose to orchestrate multiple services:

version: "3.8"
services:
  hass:
    image: ghcr.io/home-assistant/home-assistant:stable
    container_name: hass
    volumes:
      - /opt/homeassistant/config:/config
    restart: unless-stopped
    network_mode: host
  traefik:
    image: traefik:v2.5
    command:
      - "--api.insecure=true"
      - "--providers.docker"
      - "--entrypoints.web.address=:80"
    ports:
      - "80:80"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
    restart: unless-stopped

Automation: Combine Home Assistant with Node‑RED for visual programming. Use mqtt as a message bus to interconnect devices and services.

---

6. AI on a Budget: Edge Computing

The N150’s CPU is not a powerhouse, but it can handle light AI workloads—perfect for edge inference and personal assistants.

6.1. TensorFlow Lite

Install TensorFlow Lite for inference:

sudo apt install python3-pip
pip3 install tflite-runtime

Deploy a pre‑trained model for voice commands or image recognition. For example, a tiny face‑detection model can run in real time on the N150, triggering Home Assistant scenes when your family enters the room.

6.2. OpenAI Whisper

Whisper’s small models can transcribe audio locally.

pip3 install git+https://github.com/openai/whisper.git

Run a daemon that listens on a microphone input, transcribes speech, and forwards text to Home Assistant via HTTP or MQTT.

6.3. Hugging Face Inference

Use the 🤗 Inference API for heavier models, but keep the N150 as a caching proxy. The first request pulls the model to a local Docker container; subsequent requests are served from the cache, dramatically cutting latency and cost.

---

7. Keeping the Power Bill Low

Power efficiency is the crown jewel of the N150 homelab. Here are practical steps to keep consumption minimal:

Strategy	Implementation
Use the CPU’s DVFS	Enable Intel SpeedStep; set powersave governor via cpupower.
Schedule heavy workloads	Run backup or AI inference during off‑peak hours (e.g., 2 a.m.–4 a.m.) using cron.
Auto‑sleep during inactivity	Use systemd-sleep to power‑down the host if no network activity for 30 minutes.
Smart plugs	Plug the N150 into a smart plug that reports real‑time power usage (TP-Link Kasa).
Renewable energy	Pair with a solar panel or grid‑storage system; the N150’s low draw makes it ideal for micro‑grids.
Virtualization optimization	Turn off idle VMs (via virsh shutdown <name>); keep only essential containers running.

An N150 typically draws 30 W under load. Running it 24/7 translates to ~220 kWh per year—roughly $26 per month at $0.12/kWh, compared to a traditional server’s $120/month.

---

8. Case Study: A DIY Smart Home + Media Server

Scenario: 4‑room home with Alexa‑compatible voice control, a media library, and a personal AI assistant for home security.

Component	Mini‑PC	Software
Home Automation	N150	Home Assistant + MQTT
Voice Assistant	N150	Whisper + Home Assistant
Media Server	N150	Jellyfin in Docker
Backup & AI	N150 (expanded with 1 TB NVMe)	Docker + TensorFlow Lite
Power Management	N150	Uptime Kuma + PowerMeter smart plug

Results:

• 24/7 uptime with zero downtime after a 3 hour kernel upgrade.
• AI voice commands processed locally with <200 ms latency.
• Media streaming served to 8 devices simultaneously.
• Electricity savings: 150 kWh/year less than a baseline system.

---

9. Extending the Homelab

As you grow, the modular nature of the N150 allows you to add:

• USB‑C RAID arrays for redundancy.
• Dedicated AI nodes (e.g., NVIDIA Jetson Nano) for heavier inference.
• Edge‑CNC for 3D printing automation.
• Security cameras using MotionEyeOS on another mini‑PC.

Because the N150 is so compact, you can place multiple units in a single 5‑inch rack or even a shoebox, making it easy to create a distributed “edge cloud.”

---

10. Final Thoughts

The Intel N150 mini‑PC embodies the spirit of the modern homelab: low cost, low power, high flexibility. Whether you’re automating lights, running an AI assistant, or hosting a personal media server, the N150 delivers the horsepower you need without the noise and bill of a full‑scale data center.

By layering virtualization, containerization, and edge AI, you can create a super‑powered homelab that’s both efficient and scalable. And with thoughtful power‑management practices, your electricity bill stays friendly to your wallet—and the planet.

Happy hacking! 🚀

Natural Language Processing vs. Generative AI: A Friendly Guide

Ever wondered what the difference is between “natural language processing” (NLP) and “generative AI”? Both buzzwords pop up in tech news, but they’re not the same thing—though they do share a common language. This article breaks them down in everyday terms, compares their strengths and quirks, and shows how they’re changing the way we interact with computers.

---

1. What Is Natural Language Processing?

The “Understanding” Side of Language

• Definition: NLP is a branch of artificial intelligence that lets computers read, interpret, and respond to human language. Think of it as a translator that turns messy, spoken, or written words into a format a computer can understand.
• How It Works: NLP uses rules, patterns, and statistical models to dissect sentences, identify key parts (like nouns or verbs), and figure out meaning. For example, a spam filter uses NLP to spot words and phrases that signal unwanted emails.
• Real‑World Uses:
  • Voice Assistants (Siri, Alexa, Google Assistant) that listen and answer questions.
  • Chatbots that help you book flights or troubleshoot tech issues.
  • Translation Apps (Google Translate) that swap words from one language to another.
  • Text‑Mining in research papers, legal documents, or customer feedback.

A Quick Brain‑Teaser

If you asked an NLP system, “What’s the weather like?” it would parse that question, locate the keyword “weather,” then look up a weather database and give you an answer. It’s all about understanding the intent behind your words.

---

2. What Is Generative AI?

The “Creating” Side of Language

• Definition: Generative AI goes beyond understanding—it creates. Given a prompt, it can produce text, images, music, or code that feels original and often surprisingly human‑like.
• How It Works: These systems learn from massive datasets. By studying countless examples, they develop a statistical sense of how words usually follow one another. When you give it a seed (a prompt), the AI generates a continuation that fits that pattern.
• Real‑World Uses:
  • ChatGPT that writes essays, drafts emails, or even jokes.
  • DALL‑E that draws images from textual descriptions.
  • Music‑Generating AI that composes new songs.
  • Code Assistants that write snippets or debug scripts.

A Quick Brain‑Teaser

Ask a generative AI: “Write a short story about a space‑faring dog.” It will produce a narrative, sometimes in a style that feels uniquely yours, because it’s not just pulling pre‑written text—it’s making it.

---

3. Where They Overlap

Feature	NLP	Generative AI
Language	Reads & interprets	Reads & writes
Input	Human words	Human words + prompts
Output	Structured data, answers, summaries	Text, images, code
Goal	“What does this mean?”	“What can I create from this?”

Both rely on machine learning models trained on huge amounts of text (and sometimes other media). They’re both built on neural networks that learn patterns. That’s why a well‑trained generative AI can also perform NLP tasks—like summarizing a document or answering a question—because it’s essentially doing both “understanding” and “creating” in one go.

---

4. Key Differences Explained

Aspect	NLP	Generative AI
Primary Function	Understanding	Creating
Typical Outputs	Numbers, classifications, concise answers	Long-form text, images, code
Creativity	Low (mostly deterministic)	High (probabilistic, varied)
Risk of Errors	Mostly factual mistakes	Can hallucinate (invent facts)
User Control	You ask for specific data	You guide the prompt, but output can surprise

A Simple Analogy

• NLP is like a lawyer who reads a contract and tells you what it means.
• Generative AI is like a writer who drafts a brand‑new novel from a simple idea.

Both are valuable, but they serve different purposes. A lawyer’s job is to clarify existing text; a writer’s job is to create something that doesn’t yet exist.

---

5. Why the Distinction Matters

• Safety & Reliability: If you need trustworthy answers (e.g., legal advice), NLP is usually safer because it pulls from known sources. Generative AI can produce “hallucinated” facts—so it’s less reliable for high‑stakes facts.
• Creativity & Innovation: If you’re brainstorming or want a fresh perspective, generative AI shines. Think of it as a creative partner.
• Efficiency: NLP can process huge amounts of data quickly (e.g., summarizing 10,000 tweets). Generative AI is slower, as each output is a brand‑new creation.

---

6. The Future: A Blend of Both

Many of today’s tools are blending these skills. For instance, ChatGPT can read your query (NLP) and write an answer (generative). As the models improve, the line will blur—yet the core distinction remains:

• Understanding: The system’s ability to interpret what you say.
• Generating: The system’s ability to produce new content that feels natural.

Tech developers are actively working on “grounded” generative models—ones that cross-check facts before they speak. Imagine a chat assistant that can both pull up the exact Wikipedia entry and rewrite it in a witty tone—combining the best of both worlds.

---

7. Bottom Line

• NLP = Reading and interpreting language—great for data extraction, answering questions, and powering virtual assistants.
• Generative AI = Creating language, images, and more—great for storytelling, design, coding, and brainstorming.

Think of them as two sides of a coin: one flips up understanding, the other flips up creation. Together, they’re reshaping how we communicate with machines—and how those machines help us communicate with each other.

Intelligent Automation Workflows with n8n

(A research‑style overview for practitioners, architects, and developers)

---

1. What “intelligent automation” means in the n8n ecosystem

Concept	What it looks like in practice	Why it matters
AI‑powered data extraction	Use the AI node (OpenAI, Claude, Gemini, etc.) to parse PDFs, images, or structured text.	Reduces manual labeling, speeds up onboarding.
Retrieval‑Augmented Generation (RAG)	Pull documents from a vector store (Weaviate, Pinecone, Chroma) → query with an LLM → produce context‑aware answers.	Enables memory and domain knowledge inside workflows.
Agentic patterns	Single “agent” node that decides which sub‑workflow to run based on prompt or LLM output; or a team of agents that coordinate via shared state.	Allows dynamic decision‑making, task routing, and self‑learning loops.
Self‑hosting & privacy	Deploy n8n on Kubernetes or Docker‑Compose; run LLM locally (e.g., Ollama, LlamaIndex).	Control over data, compliance with GDPR, reduced cost.

Key takeaway: Intelligent workflows are not just “run‑tasks” pipelines; they are context‑aware, adaptive, and often powered by generative AI.

---

2. Core building blocks in n8n

Node / Feature	Typical use in AI workflows	Where to find it
HTTP Request / Webhook	Triggering from external systems, sending data to APIs.	Core n8n node.
AI (OpenAI, Claude, Gemini)	Generate text, embeddings, summarise, translate.	Built‑in AI node.
Code (JavaScript / Python)	Custom logic, data reshaping, calling third‑party libraries.	Native node.
SplitInBatches / Function Item	Process lists (e.g., bulk document embeddings).	Built‑in.
Vector Store connectors (Weaviate, Pinecone, Chroma)	Store & retrieve embeddings.	Community/3rd‑party nodes.
Execute Workflow	Invoke sub‑workflows (agent steps).	Built‑in.
Set / Merge / IF	Conditional branching, state management.	Core.
Cron / Timer	Scheduled refreshes of embeddings or knowledge bases.	Core.

Tip: Combine AI nodes with Execute Workflow nodes to create nested, agent‑like logic.

---

3. Typical AI‑powered workflow patterns

Pattern	What it solves	Example workflow steps
Document Ingestion & Vector Indexing	Create a searchable knowledge base.	1️⃣ Webhook → 2️⃣ Download PDF → 3️⃣ Split pages → 4️⃣ Generate embeddings (AI) → 5️⃣ Store in Weaviate.
RAG Chatbot	Context‑aware question answering.	1️⃣ Webhook (chat) → 2️⃣ Retrieve top‑k docs → 3️⃣ Construct prompt → 4️⃣ LLM generation → 5️⃣ Respond.
Agentic Task Routing	Multiple agents decide on next step.	1️⃣ Trigger → 2️⃣ Prompt LLM to choose “agent” → 3️⃣ Execute chosen sub‑workflow.
Self‑learning Loop	Fine‑tune LLM with new data.	1️⃣ Collect user feedback → 2️⃣ Store logs → 3️⃣ Periodically fine‑tune model (Code node).
Automated Content Generation	Generate reports, summaries, or social‑media posts.	1️⃣ Data source → 2️⃣ Summarise (AI) → 3️⃣ Format → 4️⃣ Post to platform.

Reference: The n8n docs’ “Advanced AI” tutorial walks through a basic RAG chatbot example (see https://docs.n8n.io/advanced-ai/intro-tutorial/).

4. Building a “starter” intelligent workflow

Below is a high‑level recipe you can copy‑paste and tweak.

1. Create a new workflow.
2. Trigger: Webhook → receives a user query ({{ $json.query }}).
3. Knowledge retrieval:
   • SplitInBatches → split query if needed.
   • AI node (model: gpt‑4o‑mini, function call: embeddings) → send query to embeddings endpoint.
   • HTTP Request → POST to vector store (/vectorsearch) with the embedding; get top‑k docs.
4. Prompt construction:
   • Set node → create a prompt that includes the retrieved docs.
5. Generate answer:
   • AI node (model: gpt‑4o‑mini) → pass prompt; capture text.
6. Respond:
   • Webhook Response → send back the LLM answer.
7. Optional: Execute Workflow → call a sub‑workflow for post‑processing (e.g., add markdown formatting).

Why this works:

• The embedding step gives the model contextual memory.
• The retrieval step ensures the answer stays factual.
• The agentic pattern (step 7) allows you to plug in more sophisticated logic later.

3.2 Create a New Screen

1. In the Project Sidebar, click + Screen.
2. Name it (e.g., “Home”).

3.3 Write a Prompt

Create a homepage with a full‑width hero banner that says “Welcome to My App” in a large, bold font, followed by a centered button that says “Get Started.” The button should link to the “Features” page.

Paste the prompt into the Prompt Editor and press Generate. Lovable will output:

// Example (React/Next.js)
export default function Home() {
  return (
    <section className="min-h-screen bg-gradient-to-r from-indigo-500 to-purple-500 flex flex-col justify-center items-center text-white">
      <h1 className="text-5xl font-extrabold mb-6">Welcome to My App</h1>
      <a href="/features" className="px-6 py-3 bg-white text-indigo-600 rounded-full font-semibold hover:bg-indigo-50">
        Get Started
      </a>
    </section>
  );
}

3.4 Refine with the Component Library

• Drag a Button component onto the canvas.
• In the properties panel, change its label, color, or link.
• Replace the generated code if you prefer a custom style.

3.5 Add Navigation

Create a new screen called Features and write a prompt:

Make a Features page with a 3‑column grid, each column containing a card with an icon, title, and short description. Use a light‑grey background.

Generate, then add a navigation bar component linking to Home and Features.

---

4. Testing & Debugging

1. Live Preview – changes appear instantly.
2. Browser Console – open dev tools to catch errors.
3. Component Inspector – click a UI element to edit its props directly.
4. Version History – revert to earlier prompt states if something breaks.

---

5. Publishing Your App

1. In the dashboard, click Publish next to your project.
2. Choose a sub‑domain (e.g., myapp.lovable.dev) or connect a custom domain.
3. Enable HTTPS (automatic).
4. Share the link or embed it in your marketing site.

---

6. Tips & Best Practices

Tip	Why It Helps
Keep prompts clear & concise	AI understands short, direct instructions better.
Use “–no…” clauses	e.g., “no border” to remove default styling.
Leverage the component library	Saves time and ensures consistency.
Iterate incrementally	Test after each prompt to catch issues early.
Comment your code	Even though it’s autogenerated, comments aid future edits.
Use version control	Store project snapshots on GitHub via the export feature.

cd my-vibe-app

You’ll get a minimal folder structure:

my-vibe-app/
├─ src/
│  └─ index.js
├─ .lovablerc
└─ package.json

3.3. Write Your First Vibe

Open src/index.js and start coding. Here’s a tiny example:

import { createApp } from 'lovable';

const app = createApp({
  title: 'Vibe Demo',
  render() {
    return `
      <h1>Hello, Vibe!</h1>
      <p>Feel the rhythm.</p>
    `;
  },
});

app.listen(3000);

Run it:

npm run dev

Visit http://localhost:3000 – you’ll see the app render instantly. Play with the code, and you’ll notice the instant feedback loop. That’s the vibe in action.

1. Before the Paws Arrive

Choosing the Right Dog

• Breed & Size: Consider your living space, activity level, and family dynamics.
• Temperament: Look for a temperament that matches your lifestyle. Many rescue shelters have detailed profiles.
• Health History: Request a veterinary report and any known hereditary conditions.

Home Preparation Checklist

Category	Item	Why It Matters
Space	Separate sleeping area (crate or puppy pad)	Consistency and safety
Gear	Leash, collar, harness, ID tags	Essential for walks and safety
Feeding	High‑quality food, bowls, feeding schedule	Establish routine early
Safety	Remove toxic plants, secure loose wires, lock cabinets	Prevent accidents
Enrichment	Chew toys, puzzle feeders	Mental stimulation
Cleaning	Dog‑safe detergent, puppy‑proof flooring	Easy cleanup of accidents

Building a Routine

Dogs thrive on predictability. Sketch out a simple daily schedule:

1. Morning: Wake, bathroom, walk, breakfast, training (5–10 min).
2. Midday: Rest, safe playtime, bathroom break.
3. Evening: Walk, dinner, family time, training, bedtime.

Stick to this rhythm; it reduces anxiety and speeds adaptation.

---

2. The Arrival Day

First Impressions

• Keep the environment calm. Avoid loud music, bright lights, or too many visitors.
• Offer a small, quiet space (crate or mat) with a blanket and a safe toy.

Introducing Your Dog to the Home

1. Room-by-Room Walkthrough: Let them sniff each area. Keep the leash short.
2. Identify Key Zones: Show the food spot, bathroom area (outside or crate), and sleeping zone.
3. Give a Name Cue: Use a friendly, high‑pitch voice. Reward with treats when they look at you.

Safety First: House‑Proofing & Initial Check‑up

• House‑Proofing: Check for choking hazards, secure cords, lock away dangerous items.
• Vet Visit: Schedule a comprehensive check‑up within 48–72 hours. Bring all medical records.

---

3. Weeks 1–4: The Settling‑In Phase

Establishing a Feeding Schedule

• Consistency: Feed at the same times each day.
• Portion Control: Use the vet’s recommendations; avoid over‑feeding.

Basic Commands & House Training

• Crate Training: Teach the dog to view the crate as a safe space. Use treats and positive reinforcement.
• Potty Routine: Take them outside after meals, naps, and play. Praise instantly.
• Name Recognition: Call their name and reward when they look.

Socialization Basics

• Controlled Exposure: Gently introduce familiar people, pets, and quiet streets.
• Positive Reinforcement: Reward calm behavior; avoid punishment.

---

4. Weeks 5–8: Building Trust & Structure

Consistency in Training

• Short Sessions: 5–10 minute training bouts keep their attention.
• Commands: “Sit,” “Stay,” “Come,” and “Leave It.”
• Progressive Difficulty: Increase distractions gradually.

Exercise & Mental Stimulation

• Daily Walks: 20–30 minutes, varying routes.
• Playtime: Fetch, tug‑of‑war, puzzle toys.
• Mental Games: Hide‑and‑seek treats, scent work.

Health Monitoring & Vet Visits

• Vaccinations: Follow the vet’s schedule (often a second booster around 8 weeks).
• Parasite Control: Start flea/tick prevention.
• Check for Symptoms: Monitor for vomiting, diarrhea, lethargy.

---

5. Weeks 9–12: Refining Skills & Strengthening Bonds

Advanced Commands & Tricks

• “Down,” “Heel,” “Wait,” “Drop It,” and gentle recall in a variety of settings.

Addressing Behavioral Issues

• Barking: Identify triggers; teach a “quiet” cue.
• Jumping: Ignore and reward calm greetings.
• Chewing: Offer appropriate chew toys; redirect if needed.

Family Integration & Routine Adjustments

• Introduce the dog to all family members, including children, on a calm basis.
• Adjust the walk schedule if everyone’s schedules change.

---

6. Weeks 13–16: Your Dog as a Mature Companion

Long‑Term Care Plan

• Diet: Transition to a balanced adult formula if the dog is nearing adulthood.
• Exercise: Tailor intensity based on breed and energy level.
• Grooming: Regular brushing, nail trimming, ear cleaning.

Continuing Education & Enrichment

• Doggy Daycare or group classes: Socialization and mental stimulation.
• New Skills: Agility, scent training, or obedience competitions.

Preparing for the Unexpected

• Emergency Plan: Know the nearest emergency clinic and have a “Dog First Aid” kit.
• Microchip & ID: Ensure they are up to date.

---

7. Key Tips & Common Pitfalls

Tip	Explanation
Positive Reinforcement	Consistently reward good behavior; dogs learn best through encouragement.
Patience	Rapid changes can overwhelm; let the dog adjust at their own pace.
Consistency Across Family	All family members must use the same commands and rules.
Avoid Punishment	Negative reinforcement can cause fear and aggression.
Early Vet Care	Early detection of health issues prevents complications.

---

Why Use Dokploy?

• Speed & Simplicity – One command to spin up a production‑ready environment.
• Control – You own the server, the data, and the secrets.
• Cost‑Effective – Only pay for the server you already have.
• Extensibility – Add custom scripts, environment variables, or run side‑by‑side services.
• Open‑Source – No lock‑in, you can tweak the source code as needed.

If you’re building a personal website, a small SaaS, or a micro‑service stack, Dokploy is an excellent “deploy‑now” solution.

---

Prerequisites

Requirement	Why	How to Install
Linux Server (Ubuntu 20.04/22.04+, Debian 11+, or other modern distro)	Dokploy runs natively on Linux.	Use your provider’s control panel or SSH.
Docker & Docker‑Compose	Dokploy itself runs inside Docker containers.	sudo apt-get install -y docker.io docker-compose
Sudo/Root Access	Installation requires privileged operations.	Use sudo or switch to root with sudo -i.
Domain name (optional, but recommended)	Lets‑Encrypt requires a domain for SSL.	Purchase through any registrar, point A record to your server.
Firewall rules	Expose HTTP (80), HTTPS (443), and the Dokploy UI port (8000 by default).	sudo ufw allow 80,443,8000

Tip: If you’re on a VPS (DigitalOcean, Hetzner, Linode, etc.), these packages are pre‑installed or easy to add.

---

Installation Methods

Dokploy offers two main installation paths:

1. Docker‑Based – Recommended for most users.
2. Native (Non‑Docker) – For those who want everything inside Docker but prefer not to run Docker as a daemon.

Below we’ll walk through the Docker approach first because it’s the simplest and most reliable.

---

4.1 Docker‑Based Installation (Recommended)

Step 1 – Install Docker & Docker‑Compose

sudo apt update && sudo apt upgrade -y
sudo apt install -y docker.io docker-compose
sudo systemctl enable --now docker

Verify:

docker --version
docker compose version

Step 2 – Create a Dedicated User (Optional but Clean)

sudo adduser dokploy
sudo usermod -aG docker dokploy   # Give Docker permissions

Log in as dokploy:

su - dokploy

Step 3 – Pull & Run Dokploy

# Pull latest Dokploy image
docker pull dokploy/dokploy:latest

# Create a persistent data directory
mkdir -p ~/dokploy/data

# Run Dokploy container
docker run -d \
  --name dokploy \
  -p 8000:8000 \
  -v ~/dokploy/data:/app/data \
  --restart unless-stopped \
  dokploy/dokploy:latest

Why /app/data?
Dokploy stores database, config files, and uploaded SSL certs here. Keeping it outside the container ensures persistence across restarts.

Step 4 – Verify

Open your browser and navigate to http://your-server-ip:8000.
You should see Dokploy’s welcome screen.

If you have a domain, point it to your server’s IP, and open http://your-domain.com:8000.

Step 5 – Secure the UI (Optional but Recommended)

• Basic Auth – Add a .htpasswd file and map the volume into the container.
• Reverse Proxy – Deploy Nginx or Traefik to expose Dokploy on port 80/443 and enforce HTTPS.

Example Nginx snippet:

server {
    listen 80;
    server_name dokploy.yourdomain.com;

    location / {
        proxy_pass http://localhost:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

Reload Nginx: sudo systemctl reload nginx

---

4.2 Native (Non‑Docker) Installation

If you prefer not to use Docker at all (e.g., you have a dedicated environment), you can run Dokploy directly via its Go binary.

1. Download the Binary

wget https://github.com/dokploy/dokploy/releases/latest/download/dokploy_$(uname -s)_$(uname -m).tar.gz
tar -xzf dokploy_*.tar.gz
sudo mv dokploy /usr/local/bin/

2. Create Data Directory

sudo mkdir -p /var/lib/dokploy
sudo chown $USER:$USER /var/lib/dokploy

3. Run Dokploy

dokploy serve --data-dir /var/lib/dokploy

4. Optional Systemd Service

Create /etc/systemd/system/dokploy.service:

[Unit]
Description=Dokploy Deployment Platform
After=network.target

[Service]
User=dokploy
ExecStart=/usr/local/bin/dokploy serve --data-dir /var/lib/dokploy
Restart=on-failure
WorkingDirectory=/var/lib/dokploy

[Install]
WantedBy=multi-user.target

Enable & start:

sudo systemctl enable --now dokploy

---

4.3 Deploying via Dokploy’s Self‑Hosting UI

Dokploy offers a Self‑Hosting button in its UI that will deploy an instance of Dokploy on your own server using Docker Compose. This is a great way to automate the entire process:

1. In the Dokploy UI, click “Self‑Hosting”.
2. Follow the on‑screen instructions – you’ll provide your server’s IP, SSH credentials, and domain.
3. The wizard will run a one‑off SSH command that pulls the necessary Docker images and configures everything.

Note: This method is only available on the public Dokploy instance; if you’re running your own local Dokploy, skip this step.

---

Getting Started After Installation

Once you’ve verified the UI, follow these quick steps to deploy your first app:

1. Create an App

   • Click “Add App” → choose “New Git App”.
   • Enter a name (e.g., my-site).
   • Add the Git repository URL (public or private; for private, you’ll need to provide SSH keys).

2. Configure Environment

   • Add environment variables under the Environment tab (e.g., NODE_ENV=production).
   • Set the Build Command and Start Command if Dokploy can’t auto‑detect them.
     Example:
     • Build: npm ci && npm run build
     • Start: npm run start

3. Add a Database

   • Click “Databases” → Add Database → choose type (PostgreSQL, MySQL, MongoDB, Redis).
   • Dokploy will spin up a Docker container and provide connection details.

4. Assign a Domain

   • Go to the Domain tab → add your domain.
   • DNS A‑record should point to your server’s IP.
   • Dokploy will request a Lets‑Encrypt cert automatically.

5. Deploy

   • Click “Deploy Now”.
   • Watch the logs in real‑time; Dokploy will install dependencies, build, and launch the app.

6. Test

   • Visit https://your-domain.com – you should see your app live!

Common Troubleshooting

Symptom	Likely Cause	Fix
Docker container fails to start	Insufficient memory or wrong port mapping	Allocate more RAM (≥512 MB) or change -p 8000:8000
HTTPS certificate not issued	DNS not propagated or port 80 blocked	Wait for DNS to propagate; open port 80; check firewall
Build fails on a framework	Missing build command	Manually set Build Command in the UI
Database not reachable	Network isolation between containers	Ensure network_mode: bridge or --link if using native installation
Logs show “Cannot resolve host”	Wrong git URL or missing SSH key	Verify repository URL; add SSH key in the Dokploy UI under Git

---

Security & Maintenance Tips

Topic	Recommendation
Firewall	Only open 80, 443, and 8000 (or your custom UI port). Use ufw or firewalld.
Updates	docker pull dokploy/dokploy:latest and docker restart dokploy every month.
Backups	Persist ~/dokploy/data to a backup location; schedule regular snapshots.

Metallosis after Titanium Implants for Spondylolisthesis

(also called “metal‑on‑metal” reaction, metal debris reaction, or metal‑related implant reaction)

---

1. What is Metallosis?

Metallosis is a localized or systemic reaction to metal particles or ions that are released from an implant. In the spine, the most common culprit is a titanium (or titanium alloy) screw, rod, cage, or plate that has been used to stabilize a spondylolisthesis (slippage of a vertebral body).

• Local tissue reaction:

  • Chronic inflammation, granuloma formation, or pseudotumor‑like mass around the implant.
  • Erosion of adjacent bone or soft tissue.

• Systemic reaction (rare with titanium):

  • Elevated serum metal ion levels (Ti, Al, Co, Cr).
  • Symptoms such as fatigue, arthralgia, or organ dysfunction if levels are high enough.

Titanium is the most biocompatible metal used in spinal implants, but it is not inert. Mechanical wear, corrosion, and micromotion can generate metal wear debris.

---

2. Why Does it Occur in Spondylolisthesis Repairs?

Factor	Why it matters
Micromotion at the fusion surface	Even after the implant is placed, slight relative motion can wear the titanium surfaces or threads, producing particles.
Corrosion in the spinal environment	Saline fluid, varying pH, and bacteria can corrode titanium, releasing ions.
Mechanical stress	The load across the spondylolisthesis can be high, especially if the fixation is short‑segment or the patient is obese, accelerating wear.
Multiple hardware components	More surfaces in contact increase the potential for debris generation.

---

3. Clinical Presentation

Symptom	Typical Timeframe	How to Recognize
Pain or “spine flare”	Weeks to months post‑surgery	Localized to the fused segment; often worsening with activity.
Swelling or palpable mass	Months to years	Firm, sometimes fluctuant swelling over the implant.
Redness, warmth, or erythema	Less common	Could indicate inflammatory reaction or infection.
Neurological deficit (rare)	Years	If the debris or inflammatory mass compresses the spinal cord or nerve roots.
Systemic symptoms (very rare)	>1 year	Fatigue, joint pain, or organ discomfort if metal ion levels rise.

Note: Many patients with titanium implants never develop metallosis. Most reactions are subtle and can be mistaken for post‑operative stiffness or typical fusion pain.

4. Diagnosis

Modality	What it Shows	When to Use
Plain radiographs	Bony changes, implant integrity	Routine follow‑up.
CT (with metal artifact reduction)	Local bone resorption, pseudotumor	Suspicion of mass or bone loss.
MRI (with metal‑artifact reduction sequences)	Soft tissue reaction, edema	When pain is disproportionate to imaging.
Ultrasound	Peri‑implant fluid or mass	Bedside screening.
Serum metal ion test	Elevated Ti or Al levels	If systemic symptoms or high‑risk implants.
Fine‑needle aspiration / biopsy	Histology: metal debris, giant cells	If mass is present or infection is suspected.

Key point: A normal radiograph does not rule out metallosis; clinical suspicion combined with advanced imaging is often required.

5. Management

Approach	Indications	Typical Steps
Observation	Mild symptoms, normal imaging, low risk of progression	Serial imaging, pain management, physiotherapy.
Medical therapy	Inflammation, mild pain	NSAIDs, physical therapy, anti‑inflammatory injections.
Hardware removal / revision	Persistent pain, progressive bone loss, pseudotumor, or systemic symptoms	Surgical removal of titanium components, possible replacement with ceramic or polymer‑reinforced alloys (e.g., cobalt‑chrome, titanium‑aluminum‑vanadium).
Biopsy & histology	Mass present	To confirm metal reaction versus tumor or infection.
Serum ion monitoring	Systemic symptoms	Repeat tests, consider chelation if levels are extremely high (rare).

Pre‑operative planning for revision

• Use non‑metallic implants if the reaction is severe (ceramic cages, polymer rods).
• Employ computer‑guided navigation to minimize soft tissue disruption.
• Consider intra‑operative frozen section to confirm absence of infection.

6. Prevention Tips for Spine Surgeons

1. Choose high‑quality titanium alloys with proven corrosion resistance.
2. Ensure proper implant placement – avoid micromotion by selecting adequate segment length and using supplemental fixation (e.g., screws + plate).
3. Minimize hardware density – reduce the number of titanium components where clinically feasible.
4. Use protective coatings (e.g., titanium nitride) that lower wear rates.
5. Educate patients on signs of metallosis and schedule regular follow‑ups.

---

7. Patient‑Facing Summary

• Most titanium implants work well and do not cause problems.
• Metallosis is rare but can lead to pain, swelling, or, rarely, systemic symptoms.
• If you notice new, worsening back pain, a mass over your spine, or systemic aches, let your surgeon know.
• Diagnosis may require imaging and blood tests.
• Treatment ranges from watchful waiting to surgical revision, depending on severity.

8. Quick Reference (for Clinicians)

Symptom	Next Step
New localized pain >2 weeks post‑op	Check plain radiograph; consider CT/MRI
Palpable mass or swelling	Ultrasound → CT/MRI; consider aspiration
Systemic fatigue or arthralgia	Serum Ti/Al ion levels; consider chelation if >5 µg/L
Progressive bone loss	Revision surgery; possibly non‑metallic hardware

Bottom Line

Titanium implants for spondylolisthesis are safe and effective, but a small subset of patients can develop metallosis—an inflammatory reaction to metal debris. Recognizing the signs early, confirming the diagnosis with imaging and blood tests, and tailoring management (from observation to revision) can prevent serious complications and restore function. If you’re experiencing new symptoms or have concerns, discuss them with your spine surgeon; a proactive approach is key.
