⚠️ Notice: Limited Maintenance

This project is no longer actively maintained. While existing releases remain available, there are no planned updates, bug fixes, new features, or security patches. Users should be aware that vulnerabilities may not be addressed.

❗ANNOUNCEMENT: Security Changes❗

TorchServe now enforces token authorization enabled and model API control disabled by default. These security features are intended to address the concern of unauthorized API calls and to prevent potential malicious code from being introduced to the model server. Refer the following documentation for more information: Token Authorization, Model API control

# Try it out
curl -X POST -d '{"prompt":"count from 1 to 9 in french ", "max_tokens": 100}' --header "Content-Type: application/json" "http://localhost:8080/predictions/model"

🚢 Quick Start LLM Deployment with Docker

#export token=<HUGGINGFACE_HUB_TOKEN>
docker build --pull . -f docker/Dockerfile.vllm -t ts/vllm

docker run --rm -ti --shm-size 10g --gpus all -e HUGGING_FACE_HUB_TOKEN=$token -p 8080:8080 -v data:/data ts/vllm --model_id meta-llama/Meta-Llama-3-8B-Instruct --disable_token_auth

# Try it out
curl -X POST -d '{"model":"meta-llama/Meta-Llama-3-8B-Instruct", "prompt":"Hello, my name is", "max_tokens": 200}' --header "Content-Type: application/json" "http://localhost:8080/predictions/model/1.0/v1/completions"

Refer to LLM deployment for details and other methods.
