+# Saturn Cloud RAPIDS + Spark Acceleration Template
+
+[](https://saturncloud.io)
+
+A production-ready template for GPU-accelerated data processing and machine learning using RAPIDS and Apache Spark on Saturn Cloud.
+
+## ๐ Quick Start
+
+### Prerequisites
+- Saturn Cloud GPU instance (A100, V100, or T4 recommended)
+
+### Installation & Setup
+
+1. **Run the setup script**:
+```bash
+cd saturn-cloud-rapids-template
+./setup_environment.sh
+```
+The script above does the complete setup of the environment.
+
+3. **Run verification tests**:
+```bash
+python test_spark.py
+```
+
+## ๐ What This Template Provides
+
+### Core Components
+- **Apache Spark 4.0.1** with Hadoop 3
+- **RAPIDS AI** (cuDF, cuML, CuPy) for GPU acceleration
+- **Python 3.10** virtual environment
+- **Jupyter Notebook** integration
+- **Production-ready pipeline examples**
+
+### Key Features
+- **10-100x faster data processing** with GPU acceleration
+- **Seamless Spark-RAPIDS integration**
+- **Automated environment configuration**
+- **Pre-built ML pipelines** with cuML
+- **Scalable from prototyping to production**
+
+## ๐ ๏ธ Usage Examples
+
+### Basic Data Processing
+```python
+from pyspark.sql import SparkSession
+import cudf
+
+# Process large datasets with Spark
+spark_df = spark.read.parquet("large_dataset.parquet")
+aggregated = spark_df.groupBy("category").agg({"value": "mean"})
+
+# Accelerate with RAPIDS
+gpu_df = cudf.from_pandas(aggregated.toPandas())
+gpu_df['normalized'] = (gpu_df['value'] - gpu_df['value'].mean()) / gpu_df['value'].std()
+```
+
+### Machine Learning Pipeline
+```python
+from cuml.ensemble import RandomForestClassifier
+from cuml.preprocessing import StandardScaler
+
+# GPU-accelerated ML
+X_train, X_test, y_train, y_test = train_test_split(features, target)
+rf_model = RandomForestClassifier(n_estimators=100)
+rf_model.fit(X_train, y_train)
+predictions = rf_model.predict(X_test)
+```
+
+### Run Production Pipeline
+```bash
+python production_pipeline.py
+```
+
+## ๐ง Configuration
+
+### Environment Variables
+- `SPARK_HOME`: Apache Spark installation path
+- `NUMBA_CUDA_ENABLE_PYNVJITLINK`: Enables RAPIDS GPU acceleration
+- `JAVA_HOME`: Java 17 installation path
+
+### Spark + RAPIDS Integration
+The template automatically configures:
+- GPU resource allocation
+- Memory optimization settings
+- Plugin activation for RAPIDS acceleration
+- Optimal parallelism settings
+
+## ๐ Troubleshooting
+
+### Common Issue: Numba/cuDF Version Conflict
+
+**Symptoms**: `RuntimeError: Cannot patch Numba: numba_cuda includes patches from pynvjitlink`
+
+**Solution**:
+```bash
+# Run the automated fix
+python fix_numba_issue.py
+
+# Or manually edit:
+nano $VIRTUAL_ENV/lib/python3.10/site-packages/pynvjitlink/patch.py
+# Find line ~284: 'raise RuntimeError(msg)'
+# Comment it out: '# raise RuntimeError(msg)'
+# Save and exit
+```
+
+### Performance Optimization Tips
+1. **Monitor GPU memory** with `nvidia-smi`
+2. **Adjust batch sizes** based on your GPU memory
+3. **Use appropriate data types** (float32 vs float64)
+4. **Enable Spark adaptive query execution**
+
+## ๐ Performance Benchmarks
+
+| Operation | CPU (Spark) | GPU (RAPIDS) | Speedup |

+# โก **FastAPI Embeddings Service (FAISS + Transformers)**
+
+*A Jupyter notebook example template demonstrating how to build a lightweight embeddings and semantic search API using FastAPI, FAISS, and Transformers โ all running interactively within [Saturn Cloud](https://saturncloud.io/).*
+
+---
+This is perfect for quickly prototyping or demonstrating **retrieval-based workflows** on **[Saturn Cloud](https://saturncloud.io/)**.
+
+---
+
+## โ๏ธ **1. Install Dependencies**
+
+> First, install all required Python libraries.
+> These packages handle embedding generation, FAISS indexing, and API serving.
+
+```python
+!pip install torch transformers sentence-transformers faiss-cpu fastapi uvicorn[standard] pydantic requests numpy
+```
+---
+
+## ๐งฉ **2. Load Embedding Model and Initialize FAISS**
+
+> We load a pre-trained SentenceTransformer model (`all-MiniLM-L6-v2`)
+> and initialize a FAISS index to store embeddings in memory.
+
+> FAISS (Facebook AI Similarity Search) provides an efficient vector index for fast nearest-neighbor queries.
+
+---
+
+## ๐ง **3. Define Core Embedding and Search Functions**
+
+> These helper functions form the โmachineโ behind the API:
+>
+> * `add_text()`: Encodes a new text and stores it in FAISS
+> * `search_texts()`: Finds similar texts to a given query
+
+---
+
+## โก **4. Create the FastAPI Application**
+
+> Now we wrap the embedding and search logic into a FastAPI service.
+> It exposes three main endpoints:
+>
+> * `/add_text`: Add and embed new text
+> * `/search`: Retrieve similar texts
+> * `/healthz`: API health check
+
+---
+
+## ๐ **5. Run the API Server Inside Jupyter**
+
+> Since Jupyter runs its own event loop, we launch Uvicorn in a **background thread**.
+
+---
+
+## โถ๏ธ **6. Start the FastAPI Service**
+
+> Launch the service.
+> Once it starts, open your browser to **[http://127.0.0.1:8002/docs](http://127.0.0.1:8002/docs)** to explore the Swagger UI.
+
+```python
+start_api_in_thread()
+```
+
+---
+
+## ๐งช **7. Test the API**
+
+> We can interact with the service directly from the notebook using HTTP requests.
+> Try adding a text and then searching for semantically similar content.
+
+### โ Add Text
+
+```python
+requests.post("http://127.0.0.1:8002/add_text",
+ json={"text": "The quick brown fox jumps over the lazy dog."}).json()
+```
+
+### ๐ Search Texts
+
+```python
+requests.post("http://127.0.0.1:8002/search",
+ json={"query": "A fast brown animal jumps over a sleepy dog", "top_k": 3}).json()
+```
+
+---
+
+## โน๏ธ **8. Stop the API**
+
+> When youโre done testing, stop the running FastAPI service gracefully.
+
+```python
+stop_api()
+```
+
+---
+
+## โ๏ธ **9. Run This Template on Saturn Cloud**
+
+This notebook is designed for **[Saturn Cloud](https://saturncloud.io/)** โ it runs entirely inside Jupyter, without needing an external process.
+
+**To deploy:**
+
+1. Create a new **Jupyter Server** resource on Saturn Cloud.
+2. Upload this notebook and install dependencies.
+3. Run the cells sequentially.
+4. Open **Port 8002** in your Saturn environment to access the running API.
+5. Use `/add_text` and `/search` to interact with your live embeddings service.

+# ๐ง LangGraph Agent Sandbox
+
+This sample notebook demonstrates how to build a **local multi-agent coding assistant** using **LangGraph**, **Transformers**, and **LangChain Sandbox** โ fully compatible with [Saturn Cloud](https://saturncloud.io/).
+
+The system allows you to:
+- Generate clean Python code from natural-language prompts.
+- Check the code for syntax and structure validity.
+- Execute the generated code safely in an isolated sandbox.
+- Interactively explore different code generation tasks โ all locally, with **no API keys required**.
+
+---
+
+## โ๏ธ What Youโll Learn
+- How to design an **agentic workflow** using LangGraph.
+- How to use **local transformer models (Phi-3 Mini)** for reasoning.
+- How to integrate a **safe execution sandbox** (with local fallback).
+- How to run multi-stage LLM pipelines entirely within Saturn Cloud.
+
+---
+
+## ๐งฉ Notebook Structure
+
+| Stage | Description |
+|--------|--------------|
+| **1. Install Dependencies** | Installs LangGraph, LangChain, and related libraries. |
+| **2. Load Model & Sandbox** | Loads the local Hugging Face model and initializes a secure sandbox (with fallback). |
+| **3. Define Workflow Agents** | Builds LangGraph nodes for Code Generation, Syntax Checking, and Execution. |
+| **4. Batch Testing** | Runs several example coding tasks through the full pipeline. |
+| **5. Interactive Mode** | Launches an interactive terminal to test your own code prompts. |
+
+---
+
+## ๐ How to Run on Saturn Cloud
+
+1. **Open this template** in your Saturn Cloud environment.
+2. Run all cells sequentially from top to bottom.
+3. The local model (`Phi-3-mini`) will load automatically.
+4. Explore the pre-loaded test prompts or use the **interactive assistant** in Stage 5.
+5. All runs execute securely inside your Saturn Cloud instance โ no external API calls.
+

+# ๐ NIM / TGI Server โ Drop-In API
+
+**Tech Stack:** NVIDIA NIM + TGI (Text Generation Inference)
+**Built for:** Saturn Cloud Custom Templates
+โก๏ธ [https://saturncloud.io/](https://saturncloud.io/)
+
+---
+
+## ๐ง Overview
+
+This template provides a **plug-and-play inference server** that supports **two interchangeable LLM backends**:
+
+| Backend | Description | Use Case |
+| -------------------- | ------------------------------------------------------------ | --------------------------------------------------------------- |
+| **NVIDIA NIM Cloud** | Fully hosted LLMs on NVIDIA's high-performance GPU cloud | High-accuracy, large models (Qwen 80B, Mistral, Nemotron, etc.) |
+| **Local TGI Server** | Lightweight local model running via HuggingFace Transformers | Fast prototyping, offline usage |
+
+The API exposes **the same unified interface** for both backends, so users can switch engines without changing frontend code.
+
+This is ideal for **Saturn Cloud Data Science workflows**, allowing teams to quickly integrate LLM inference inside their notebooks, pipelines, or applications.
+
+---
+
+# ๐ Project Structure
+
+```
+NIM-TGI-Server/
+โ
+โโโ server.py # Main FastAPI server (unified interface)
+โโโ backend_tgi.py # Local TGI backend (SmolLM)
+โโโ backend_nim.py # NVIDIA cloud backend
+โโโ cli.py # CLI tool (select backend from terminal)
+โโโ requirements.txt
+โโโ README.md # (this file)
+```
+
+---
+
+# โ๏ธ 1. Environment Setup
+
+## **Create and activate a virtual environment**
+
+### Linux / MacOS
+
+```bash
+python -m venv venv
+source venv/bin/activate
+```
+
+### Windows (PowerShell)
+
+```powershell
+python -m venv venv
+venv\Scripts\activate
+```
+
+---
+
+## **Install dependencies**
+
+```bash
+pip install -r requirements.txt
+```
+
+---
+
+# ๐ 2. Getting a NVIDIA NIM API Key
+
+To use the **NIM Cloud backend**, you need an **NVIDIA AI Foundation API Key**.
+
+### Steps:
+
+1. Visit:
+ ๐ [https://build.nvidia.com/explore/discover](https://build.nvidia.com/explore/discover)
+2. Sign in with NVIDIA account
+3. Open your "API Keys" panel
+4. Click **Create New API Key**
+5. Copy the key
+6. **Paste it into `backend_nim.py`**, replacing:
+
+```python
+API_KEY = "nvapi-xxxxxxxxxxxxxxxxxxxx"
+```
+
+โ ๏ธ **Note:**
+This template currently embeds the key directly for simplicity, but in production you should store it in environment variables or a secret manager.
+
+---
+
+# ๐ง 3. Backend Models
+
+## **A. NVIDIA NIM Backend (Cloud)**
+
+* Model used: `qwen/qwen3-next-80b-a3b-instruct`
+* Endpoint: `https://integrate.api.nvidia.com/v1`
+* Requires API Key
+* Supports streaming + large prompts
+
+## **B. Local TGI Backend (Lightweight CPU/GPU)**
+
+* Model: `HuggingFaceTB/SmolLM-1.7B-Instruct`
+* Runs entirely inside Python (no Docker needed)
+* Great for local experimentation
+
+---
+
+# ๐ 4. Running the Server
+
+Start FastAPI server:
+
+```bash
+uvicorn server:app --reload
+```
+
+Youโll see:
+
+```
+INFO: Uvicorn running on http://127.0.0.1:8000
+```
+
+---
+
+# ๐งช 5. Testing the Server
+
+## A. Test Local TGI Model
+
+**POST /chat/local**
+
+### Curl:
+
+```bash
+curl -X POST -F "prompt=Explain machine learning" http://localhost:8000/chat/local
+```
+
+### Expected Response:
+
+```json
+{
+ "backend": "tgi-local",
+ "response": "Machine learning is..."
+}
+```
+
+---
+
+## B. Test NVIDIA NIM Model
+
+**POST /chat/nim**
+
+### Curl:
+
+```bash
+curl -X POST -F "prompt=Write a short poem" http://localhost:8000/chat/nim
+```
+
+### Streaming:
+
+```bash
+curl -N -X POST -F "prompt=Tell me a story" -F "stream=true" http://localhost:8000/chat/nim
+```
+
+---
+
+# ๐ฅ๏ธ 6. Command-Line Interface (CLI)
+
+The template includes a **CLI wrapper**:
+
+### Local TGI:
+
+```bash
+python cli.py --backend local "Explain photosynthesis"
+```
+
+### NVIDIA NIM:
+
+```bash
+python cli.py --backend nim "Write 5 facts about Jupiter"
+```
+
+Streaming output works automatically.
+
+---
+
+# ๐ก 7. Using with Saturn Cloud
+
+This template is designed as a **plug-and-play server component** inside Saturn Cloud:
+
+* Run the server inside a Jupyter workspace
+* Use the API from notebooks or external apps
+* Swap between local inference (TGI) and cloud inference (NIM)
+* Ideal for ML research, RAG systems, agent development, and batch inference jobs
+
+Saturn Cloud provides scalable Jupyter environments with GPUs:
+๐ [https://saturncloud.io/](https://saturncloud.io/)
+
+---
+
+# โ๏ธ 8. Summary
+
+This template provides:
+
+### **โ A drop-in inference server**
+
+Supports both NVIDIA Cloud NIM and local TGI backends.
+
+### **โ Ready to use in Saturn Cloud**
+
+Works inside a GPU instance or CPU instance.
+
+### **โ Unified API**
+
+Same route structure for both engines.
+
+### **โ Full CLI + server support**
+
+### **โ Ideal foundation for:**
+

+# ๐ง RAG Mini Docs Q&A
+
+A lightweight **Retrieval-Augmented Generation (RAG)** system that lets you drop `.txt` files into a folder and ask natural-language questions about them.
+
+This template combines:
+
+* **SentenceTransformers** for document embeddings
+* **ChromaDB** for vector storage & retrieval
+* **๐ค Transformers (FLAN-T5)** for answer generation
+* **FastAPI** for serving an interactive Q&A API
+
+Designed for fast prototyping and educational use on **[Saturn Cloud](https://saturncloud.io/)**.
+
+---
+
+## ๐ 1. Get Started โ Understand the Folder Layout
+
+Before you start coding, review the project structure below.
+Each file serves a clear role; ensure youโre working from the correct one.
+
+```
+NVIDIA_RAG-MINI/
+โโ data/ # Folder for your .txt documents
+โ โโ saturndoc.txt # Sample document included for testing
+โโ rag_machine.py # Core logic: embeddings, Chroma, QA engine
+โโ rag-api.py # REST API built with FastAPI
+โโ requirements.txt
+```
+
+๐ **Action:** Create or upload `.txt` files into the `data/` folder before running the template.
+A sample file named **`saturndoc.txt`** is already included โ you can use it immediately to test model training and query responses.
+
+---
+
+## ๐งฉ 2. Set Up the Environment
+
+To run this project, youโll need Python โฅ 3.10.
+If youโre using **Saturn Cloud**, create a new environment and install dependencies from `requirements.txt`.
+
+### โ๏ธ Step-by-step
+
+```bash
+# (optional) create a fresh virtual environment
+python -m venv rag-env
+source rag-env/bin/activate # or .\rag-env\Scripts\activate on Windows
+
+# install dependencies
+pip install -r requirements.txt
+```
+
+### ๐ฆ requirements.txt
+
+```text
+torch>=2.2.0
+transformers>=4.44.0
+sentence-transformers>=3.0.0
+chromadb>=0.5.0
+fastapi>=0.115.0
+uvicorn[standard]>=0.30.0
+pydantic>=2.7.0
+tqdm>=4.66.0
+```
+
+๐ **Action:** Run the install command inside your active environment before executing any Python file.
+
+---
+
+## โ๏ธ 3. Configure Models and Paths
+
+All configuration happens inside **`rag_machine.py`**.
+Defaults are already suitable for most cases:
+
+```python
+CHROMA_DIR = "rag_chroma_store" # Persistent database for embeddings
+DATA_DIR = Path("data") # Directory containing your .txt files
+EMBED_MODEL = "sentence-transformers/all-MiniLM-L6-v2"
+LLM_MODEL = "google/flan-t5-base"
+```
+
+๐ **Action:**
+If you want faster inference, you can change `LLM_MODEL` to `google/flan-t5-small`.
+If you have a GPU, keep `flan-t5-base` or try `flan-t5-large`.
+
+---
+
+## ๐ป 4. Run in CLI Mode โ Test the RAG Machine
+
+Use this mode for quick experimentation.
+The script loads models, indexes your `.txt` files, and opens an interactive prompt.
+
+```bash
+python rag_machine.py
+```
+
+Youโll see output similar to:
+
+```
+๐ง Starting RAG Machine (Transformers + Chroma)...
+โป๏ธ Reindexing documents...
+๐ Indexing 5 documents...
+โ
Indexed 5 documents successfully.
+๐ Current collection size: 5 documents
+โ Enter your question (or 'exit'):
+```
+
+๐ **Action:**
+Type a question like
+`What is this project about?`
+and the model will respond based on your documents.
+
+> You can use the included **`saturndoc.txt`** file for your first run โ itโs already in the `data/` folder and serves as a ready-made example for testing and model training.
+
+---
+
+## ๐ 5. Run as an API โ Serve Questions via HTTP
+
+Now, letโs turn your RAG engine into a service.
+Start the FastAPI server with Uvicorn:
+
+```bash
+uvicorn rag-api:app --reload
+```
+
+Once running, open your browser at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
+to explore the built-in Swagger interface.
+
+### ๐งญ Endpoints
+
+| Endpoint | Method | Description |
+| ---------------------- | ------ | -------------------------------------------------- |
+| `/query` | POST | Submit a question and get an answer |
+| `/reload` *(optional)* | POST | Reindex `.txt` files without restarting the server |
+
+### Example Query
+
+```bash
+curl -X POST "http://127.0.0.1:8000/query" \
+ -H "Content-Type: application/json" \
+ -d "{\"query\": \"What does the onboarding doc say?\"}"
+```
+
+Response:
+
+```json
+{
+ "result": "The onboarding doc explains the project setup and data structure."
+}
+```
+
+๐ **Action:** Use `/query` to test, and `/reload` whenever you add new `.txt` files.
+
+---
+
+## ๐ 6. How It Works (Conceptually)
+
+1. **Document Loading** โ Reads all `.txt` files from `data/`.
+2. **Embedding Generation** โ Converts text into dense vectors using SentenceTransformers.
+3. **Vector Storage** โ Saves these embeddings persistently in **ChromaDB** (`rag_chroma_store/`).
+4. **Retrieval** โ Finds the most relevant text chunks for your query.
+5. **LLM Answering** โ Passes retrieved context + query into **FLAN-T5** to generate the final answer.
+
+๐ **Action:** Skim through `rag_machine.py` to see how each step is implementedโyou can easily swap models or add chunking later.
+
+---
+
+## ๐ 7. Reindex vs Reuse
+
+* **`reindex=True`** โ Clears and rebuilds embeddings from scratch
+* **`reindex=False`** โ Loads existing persistent store (faster)
+
+```python
+index_documents(reindex=True) # rebuild everything
+index_documents(reindex=False) # reuse old vectors
+```
+
+๐ **Action:**
+Use reindexing only after you add or update text files in `data/`.
+The included **`saturndoc.txt`** is already indexed by default when you run the script for the first time โ so you can test immediately without adding new documents.
+
+---
+
+## ๐งฉ 8. Best Practices
+
+* Keep each text file focused on one topic for cleaner retrieval.
+* For long documents, consider manually splitting them into sections.
+* If using CPU only, choose smaller models for faster inference.
+* Delete the `rag_chroma_store/` folder to fully reset the database.
+
+---
+
+## ๐ฐ๏ธ 9. Deploying on Saturn Cloud
+
+You can easily host this on **Saturn Cloud**:
+
+1. Create a new Jupyter or VS Code resource.
+2. Upload this project folder.
+3. Install requirements:
+
+ ```bash
+ pip install -r requirements.txt
+ ```
+4. Run `python rag_machine.py` to test indexing.
+5. Launch the API:
+
+ ```bash
+ uvicorn rag-api:app --host 0.0.0.0 --port 8000
+ ```
+6. Expose port **8000** in your Saturn environment to access it externally.

+# ๐ Ray Serve LLM API โ Qwen 1.5B (vLLM)
+
+This template shows how to deploy a **Qwen2.5-1.5B-Instruct LLM** using:
+
+* **Ray Serve**
+* **vLLM**
+* **OpenAI-compatible API format**
+
+You get a local inference server running at:
+
+```
+http://127.0.0.1:8000/v1/chat/completions
+```
+
+This template is designed for **Saturn Cloud custom templates** so users can plug-and-play LLM inference environments with GPU acceleration.
+
+๐ **Back to Saturn Cloud โ [https://saturncloud.io](https://saturncloud.io)**
+
+---
+
+## ๐ Features
+
+* Fully OpenAI-compatible API endpoint
+* Deploys Qwen 1.5B using vLLM (fast inference)
+* Simple Ray Serve deployment
+* Example client request included
+* Clean and minimal code structure
+* Works inside Jupyter or full terminal environment
+
+---
+
+## ๐ฆ Requirements
+
+The notebook installs everything automatically:
+
+```
+torch
+transformers
+ray[serve, llm]
+fastapi
+uvicorn
+requests
+huggingface_hub
+```
+
+GPU recommended for optimal performance.
+
+---
+
+## ๐ Project Structure
+
+```
+ray-serve-llm/
+โ
+โโโ serve_llm.py # Ray Serve deployment definition
+โโโ start_server.py # Ray launcher (if using outside notebook)
+โโโ test_client.py # Example API client test
+โโโ ray_serve_llm_template.ipynb # Full Jupyter notebook template (generated)
+```
+
+---
+
+## โถ๏ธ How It Works
+
+### 1. Write your Ray Serve deployment file
+
+Defines:
+
+* Model ID (`Qwen2.5-1.5B-Instruct`)
+* Engine config
+* Autoscaling
+* OpenAI-compatible app
+
+### 2. Start Ray and deploy the model
+
+Ray Serve loads the model via vLLM and exposes the API.
+
+### 3. Send a test request
+
+JSON API format identical to OpenAI:
+
+```python
+payload = {
+ "model": "qwen-1.5b",
+ "messages": [{"role": "user", "content": "Explain API design."}]
+}
+```
+
+### 4. Extract the assistant text
+
+```python
+res = out.json()["choices"][0]["message"]["content"]
+```
+
+---
+
+## ๐ Conclusion
+
+This template provides a clean, reproducible Ray Serve LLM deployment that works both in Jupyter and full terminal mode.
+You can adapt it to larger models, scale it across nodes, or wrap it inside FastAPI.

+# ๐ง LLM Inference with vLLM 7B
+
+**Saturn Cloud | GPU-Optimised Template**
+
+Run and serve large language models (LLMs) efficiently using **vLLM**, a high-performance inference and serving engine designed for speed and scalability.
+This Saturn Cloud template demonstrates how to deploy **7B-class models** such as *Mistral*, *Llama*, or *Gemma* for text generation and interactive inference.
+
+---
+
+## ๐ Overview
+
+**vLLM** delivers lightning-fast text generation through techniques such as **PagedAttention**, **continuous batching**, and **quantisation**.
+On **Saturn Cloud**, this notebook enables you to:
+
+* Deploy and test 7B-class LLMs for inference and serving.
+* Scale seamlessly from a single GPU to **multi-GPU clusters**.
+* Experiment interactively or integrate models into larger data-science pipelines.
+
+> โ๏ธ Fully compatible with Saturn Cloudโs managed GPU environments and ready for immediate use.
+
+---
+
+## ๐งฉ Features
+
+* **Pre-configured vLLM environment** for fast setup.
+* **Support for NVIDIA GPUs** (A10G, A100) and multi-GPU scaling.
+* **Quick-start workflow**: load, run, and test model prompts.
+* **Local API-style inference** via vLLMโs serving engine.
+* **Interactive prompt input** for experimentation.
+
+---
+
+## ๐ Requirements
+
+* **Saturn Cloud account** with GPU instance access.
+* Python โฅ 3.12
+* Compatible with **CUDA 12.0+** and **Transformers โฅ 4.40**
+
+All dependencies are pre-installed when running the notebook on Saturn Cloud.
+
+---
+
+## ๐ก Usage
+
+1. **Open the template** in Saturn Cloud.
+2. **Select a GPU instance** (A10G or A100 recommended).
+3. **Run the notebook cells sequentially** to:
+
+ * Install dependencies
+ * Configure vLLM settings
+ * Load and test your model
+ * Input prompts interactively to generate text
+
+> For production, vLLM can also serve models as an **OpenAI-compatible API** using the `vllm serve` command.

+# **vLLM Server for Meta-Llama-3-70B-Instruct**
+
+This template provides a **production-ready deployment environment** on **Saturn Cloud** to serve the **Meta-Llama-3-70B-Instruct** model using the high-performance **vLLM** inference engine and a FastAPI web API.
+
+โก๏ธ **Saturn Cloud lets you quickly launch multi-GPU machines to run large-scale models like Llama-3 70B. Learn more:**
+[https://saturncloud.io](https://saturncloud.io)
+
+---
+
+## **๐ Overview**
+
+The **Meta-Llama-3-70B-Instruct** model is a powerful open-source LLM from Meta AI.
+This template demonstrates how to deploy it efficiently using:
+
+* **Model:** `meta-llama/Meta-Llama-3-70B-Instruct`
+* **Inference Engine:** vLLM
+* **API Interface:** FastAPI (OpenAI-compatible)
+* **Precision:** bfloat16
+* **Parallelism:** Tensor Parallelism across 4 GPUs
+* **Use Cases:** Chatbots, RAG systems, model serving backends, enterprise AI apps
+
+vLLM provides optimized **PagedAttention**, **continuous batching**, and multi-GPU scalingโresulting in **significantly faster inference** compared to HuggingFace Transformers.
+
+---
+
+## **๐ป Requirements & Setup**
+
+Running a 70B parameter model requires substantial hardware and proper authentication.
+
+---
+
+### **1. Hardware Requirements**
+
+To run Llama-3 70B with vLLM, you need:
+
+| Component | Minimum Requirement |
+| ---------------------- | -------------------------------------------------- |
+| **GPUs** | 4ร GPUs (A40 48GB, RTX 3090/4090, or 2ร A100 80GB) |
+| **VRAM** | ~140GB total (bfloat16 precision) |
+| **Disk Space** | **150GB+** to store model weights |
+| **Tensor Parallelism** | `tensor_parallel_size = 4` |
+
+This template is suited for Saturn Cloud multi-GPU instances.
+
+---
+
+### **2. Hugging Face Authentication (Required)**
+
+Llama-3 models are **license-restricted** ("gated").
+You must authenticate before downloading.
+
+#### **Steps:**
+
+1. **Accept the License**
+ Visit:
+ [https://huggingface.co/meta-llama/Meta-Llama-3-70B-Instruct](https://huggingface.co/meta-llama/Meta-Llama-3-70B-Instruct)
+
+2. **Log in via CLI**
+
+ ```bash
+ hf auth login
+ ```
+
+ Paste your HF access token.
+
+3. **Token in Script**
+ A placeholder token is included for testing, but **you must use your own token** in production.
+
+
+---
+
+### **3. Environment Setup**
+
+#### Create & activate your Python environment:
+
+```bash
+python3 -m venv env
+source env/bin/activate
+```
+
+#### Install dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+All required libraries (vLLM, FastAPI, Uvicorn, HF Hub support) are included inside `requirements.txt`.
+
+---
+
+## **๐ Running the Model**
+
+### **Step 1 โ Start the API Server**
+
+Launch the vLLM FastAPI server:
+
+```bash
+python start_server.py
+```
+
+You will see logs for:
+
+* GPU detection
+* Model download progress
+* Tensor parallel initialization
+* Engine warm-up
+
+When ready:
+
+```
+INFO: Uvicorn running on http://0.0.0.0:8000
+```
+
+Your vLLM server is now live and accepting OpenAI-style requests.
+
+---
+
+### **Step 2 โ Test Using the Client Script**
+
+In a separate terminal window:
+
+```bash
+source env/bin/activate
+python test_client.py
+```
+
+You will receive a JSON response similar to:
+
+```json
+{
+ "choices": [
+ {
+ "message": {
+ "content": "Tensor parallelism is a technique that..."
+ }
+ }
+ ]
+}
+```
+
+This confirms the vLLM server is functioning correctly.
+
+---
+
+## **๐ Notes for Saturn Cloud Users**
+
+This template is ideal for running on **Saturn Cloud GPU clusters**, which provide:
+
+* Multi-GPU instances compatible with vLLM
+* Prebuilt CUDA, NCCL, Python environments
+* Fast storage needed for models of this size
+* Ability to schedule long-running inference servers
