Lorax

Lorax is an open-source, Python-based inference server that hosts language models with LoRA adapters and serves requests through shared GPU infrastructure. It supports dynamically loading adapters per request and batching requests that use different adapters.

Understand the project

Practical overview

When it fits

Use Lorax when you need to operate a shared inference server for a base model and multiple LoRA fine-tunes, with adapter selection handled per request.

Who it is for

  • Infrastructure teams serving multiple fine-tuned language-model variants.
  • Developers building an inference endpoint that routes requests to LoRA adapters.
  • Operators deploying model-serving infrastructure with Docker or Kubernetes.

Documented uses

  • Serve a base language model with task-specific adapter weights.
  • Select and load a LoRA adapter for an inference request.
  • Batch requests using different adapters together.
  • Expose model inference through REST, Python client, or OpenAI-compatible chat APIs.
Before you choose

Requirements & limits

The project is open source under the Apache-2.0 license. The documented setup uses Linux, Nvidia GPU hardware, compatible CUDA drivers, Docker, and Nvidia Container Toolkit.

  • GPU requirements are specific: the documented minimum is an Nvidia Ampere-generation GPU or newer.
  • The project separates pretrained base-model weights from task-specific adapter weights; confirm that the desired architecture and adapter format are supported.
  • The repository lists REST, Python client, and OpenAI-compatible chat interfaces.
  • Prebuilt Docker images, Helm charts, Prometheus metrics, distributed tracing, and token streaming are listed project capabilities.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Launch the Docker server

Start a Lorax server with the documented Mistral base model.

Before you start

  • Linux
  • Nvidia Ampere-generation GPU or newer
  • CUDA 11.8-compatible device drivers or later
  • Docker and Nvidia Container Toolkit

Steps

  1. Install Nvidia Container Toolkit.

  2. Run sudo systemctl daemon-reload and sudo systemctl restart docker.

  3. Set the documented model identifier to mistralai/Mistral-7B-Instruct-v0.1 and run the provided Docker command, exposing port 8080 and mounting a local data directory.

Expected outcome

A Lorax server is launched with the specified base model using the repository's Docker example.

Guide limitations

  • The guide requires Nvidia GPU infrastructure and Linux.
  • The example documents server launch, not a successful deployment test or production configuration.
