📣Latest Updates

[25/07/04] We now support quantization for Hunyuan/Qwen2.5/Qwen3/DeepSeek-R1-Distill-Qwen and other models, including INT8/FP8/INT4 algorithms. We also opensource Qwen3-8B`s Eagle3 model weight.

Coming soon:

Support W4A8 quantization for DeepSeek-R1.
Support quantization for multimodal models like Qwen-VL.
Release of new algorithm for speculative sampling.

🌟Key Features

Highly Integrated: This toolkit integrates mainstream compression algorithms into a unified framework, offering developers one-click access with exceptional ease of use.
Continuous Innovation: Beyond integrating widely-used industry algorithms, we are continuously researching better compression algorithms, which will be gradually open-sourced in the future.
Performance-Driven: We continuously optimize end-to-end performance in model compression workflows and algorithm deployment, such as enabling quantization of models like Qwen3-235B and DeepSeek-R1 on a single GPU.

💼Supported Models

🛎️How to Use

Install AngelSlim

We recommend using pip to install the latest stable version of AngelSlim:

pip install angelslim

Alternatively, you can clone the repository and install from source in editable mode:

cd AngelSlim && python setup.py install

For more detailed installation instructions, please refer to the Installation Documentation.

Quick Start

After installing AngelSlim, you can quickly start by running the following script to perform static FP8 quantization on the Qwen3-1.7B model:

One-click Start

python3 tools/run.py -c configs/qwen3/fp8_static/qwen3-1_7b_fp8_static.yaml

This example will load the HuggingFace model and perform activation value calibration using the dataset specified in the config file, saving the quantized model weights.
Code-based Start

To perform dynamic FP8 quantization on Qwen3-1.7B:

python
1from angelslim.engine import Engine 2 3slim_engine = Engine() 4# Prepare model 5slim_engine.prepare_model(model_name="Qwen", model_path="Qwen/Qwen3-1.7B",) 6# Initialize compressor 7slim_engine.prepare_compressor("PTQ", default_method="fp8_dynamic") 8# Compress model 9slim_engine.run() 10# Save compressed model 11slim_engine.save("./output")

For more details, please refer to the Quick Start Documentation.

🖥️ Deployment and Testing

1. API Service Deployment

After specifying the quantized model path MODEL_PATH, you can deploy an OpenAI-compatible API service using the following LLMs inference frameworks:

vLLM

Use the following script to launch a vLLM server, recommended version vllm>=0.8.5.post1. For MOE INT8 quantized models, vllm>=0.9.0 is required.

bash deploy/run_vllm.sh $MODEL_PATH

SGLang

Use the following script to launch a SGLang server, recommended version sglang>=0.4.6.post1.

bash deploy/run_sglang.sh $MODEL_PATH

2. Service Invocation

Invoke requests via OpenAI's API format:

bash deploy/openai.sh $MODEL_PATH

3. Performance Evaluation

Evaluate the performance of quantized model using lm-evaluation-harness, recommended versionlm-eval>=0.4.8:

bash deploy/lm_eval.sh $MODEL_PATH

For more detaileds, please refer to the Deployment Documentation.
