🌟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.

🛎️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

Quantization

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:

from angelslim.engine import Engine

slim_engine = Engine()
# Prepare model
slim_engine.prepare_model(model_name="Qwen", model_path="Qwen/Qwen3-1.7B",)
# Initialize compressor
slim_engine.prepare_compressor("PTQ", default_method="fp8_dynamic")
# Compress model
slim_engine.run()
# Save compressed model
slim_engine.save("./output")

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

Speculative_Decoding

Eagle3 PyTorch Performance Testing

After installing AngelSlim, you can quickly start Eagle3 PyTorch performance testing with the following script:

python3 tools/spec_benchmark.py \
    --base-model-path /path/to/base/model \
    --eagle-model-path /path/to/eagle/model \
    --model-id your_model_id \
    --mode both

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

Deployment and Testing

1. Offline Inference

If you need to load a quantized model via transformers, please set the deploy_backend: huggingface in the global configuration before quantizing the model, or manually modify the ignored_layers field in the config.json file located in the quantized model output directory to ignore.

To test offline inference with a quantized model loaded via transformers, run the following command:

python deploy/offline.py $MODEL_PATH

Where MODEL_PATH is the path to the quantized model output.

2. 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

3. Service Invocation

Invoke requests via OpenAI's API format:

bash deploy/openai.sh $MODEL_PATH

4. 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.
