LMDeploy: A Comprehensive Toolkit for Large Language Model Deployment

Overview

LMDeploy is an open-source toolkit designed for the efficient compression, deployment, and serving of Large Language Models (LLMs) and Vision-Language Models (VLMs). With its innovative features, LMDeploy enhances performance while simplifying the deployment process.

Core Features

• Efficient Inference: Achieve up to 1.8x higher request throughput compared to vLLM through features like persistent batching, blocked KV cache, and tensor parallelism.
• Effective Quantization: Supports weight-only and K/V quantization, boasting 2.4x better performance than FP16 during 4-bit inference.
• Effortless Distribution Server: Easily deploy multi-model services across machines with a robust request distribution service.
• Interactive Inference Mode: Maintains dialogue history by caching attention data, streamlining multi-round conversations.
• Excellent Compatibility: Seamlessly integrates KV Cache Quant, AWQ, and Automatic Prefix Caching.

How to Use

To get started, users can follow the comprehensive documentation that includes installation guides and quick-start tutorials. LMDeploy supports various models and offers pipelines for both offline and online inference.

Benefits for Users

LMDeploy empowers users to deploy models efficiently, reduce latency, and enhance user experience through interactive features. Its open-source nature allows for community-driven improvements and flexibility.

Alternatives

While LMDeploy stands out for its unique features, alternatives like Hugging Face Transformers and TensorFlow Serving may also be considered, depending on specific project requirements.
