# FastDeploy : Inference and Deployment Toolkit for LLMs and VLMs based on PaddlePaddle
|
|
|
|
## News
|
|
|
|
**[2025-11] FastDeploy v2.3 is newly released!** It adds deployment support for two major models, [ERNIE-4.5-VL-28B-A3B-Thinking](docs/get_started/ernie-4.5-vl-thinking.md) and [PaddleOCR-VL-0.9B](docs/best_practices/PaddleOCR-VL-0.9B.md), across multiple hardware platforms. It further optimizes comprehensive inference performance and brings more deployment features and usability enhancements. For all the upgrade details, refer to the [v2.3 Release Note](https://github.com/PaddlePaddle/FastDeploy/releases/tag/v2.3.0).
|
|
|
|
**[2025-09] FastDeploy v2.2**: It now offers compatibility with models in the HuggingFace ecosystem, has further optimized performance, and newly adds support for [baidu/ERNIE-21B-A3B-Thinking](https://huggingface.co/baidu/ERNIE-4.5-21B-A3B-Thinking)!

|
## About
|
|
|
|
**FastDeploy** is an inference and deployment toolkit for large language models and visual language models based on PaddlePaddle. It delivers **production-ready, out-of-the-box deployment solutions** with core acceleration technologies:
|
|
|
|
- 🚀 **Load-Balanced PD Disaggregation**: Industrial-grade solution featuring context caching and dynamic instance role switching. Optimizes resource utilization while balancing SLO compliance and throughput.
|
|
- 🔄 **Unified KV Cache Transmission**: Lightweight high-performance transport library with intelligent NVLink/RDMA selection.
|
|
- 🤝 **OpenAI API Server and vLLM Compatible**: One-command deployment with [vLLM](https://github.com/vllm-project/vllm/) interface compatibility.
|
|
- 🧮 **Comprehensive Quantization Format Support**: W8A16, W8A8, W4A16, W4A8, W2A16, FP8, and more.
|
|
- ⏩ **Advanced Acceleration Techniques**: Speculative decoding, Multi-Token Prediction (MTP) and Chunked Prefill.
|
|
- 🖥️ **Multi-Hardware Support**: NVIDIA GPU, Kunlunxin XPU, Hygon DCU, Iluvatar GPU, Enflame GCU, MetaX GPU, Intel Gaudi etc.
|
|
