NOS is a fast and flexible PyTorch inference server that runs on any cloud or AI HW.
🛠️ Key Features

👩‍💻 Easy-to-use: Built for PyTorch and designed to optimize, serve and auto-scale Pytorch models in production without compromising on developer experience.
🥷 Multi-modal & Multi-model: Serve multiple foundational AI models (LLMs, Diffusion, Embeddings, Speech-to-Text and Object Detection) simultaneously, in a single server.
⚙️ HW-aware Runtime: Deploy PyTorch models effortlessly on modern AI accelerators (NVIDIA GPUs, AWS Inferentia2, AMD - coming soon, and even CPUs).
☁️ Cloud-agnostic Containers: Run on any cloud (AWS, GCP, Azure, Lambda Labs, On-Prem) with our ready-to-use inference server containers.

🔥 What's New

[Dec 2023] 🛝 [repo] We open-sourced the NOS playground to help you get started with more examples built on NOS!

🚀 Quickstart
We highly recommend that you go to our quickstart guide to get started. To install the NOS client, you can run the following command:
conda create -n nos python=3.8 -y
conda activate nos
pip install torch-nos

Once the client is installed, you can start the NOS server via the NOS serve CLI. This will automatically detect your local environment, download the docker runtime image and spin up the NOS server:
nos serve up --http --logging-level INFO

You are now ready to run your first inference request with NOS! You can run any of the following commands to try things out. You can set the logging level to DEBUG if you want more detailed information from the server.
👩‍💻 What can NOS do?
💬 Chat / LLM Agents (ChatGPT-as-a-Service)

NOS provides an OpenAI-compatible server with streaming support so that you can connect your favorite OpenAI-compatible LLM client to talk to NOS.
