AngelSlim integrates mainstream compression algorithms into a unified framework with one-click access. Supports FP8/INT8/INT4/NVFP4/1.25-bit quantization, pruning, Eagle3 speculative decoding, and diffusion model compression for LLMs, VLMs, and audio models.
uv pip install angelslim
import angelslim as slim
# FP8 static quantization
model = slim.quantize(model, dtype="fp8_static", qconfig="default")
# INT4 GPTQ
model = slim.quantize(model, dtype="int4_gptq", dataset="wikitext2")
| Method | Precision | Best For |
|---|---|---|
| FP8-Static/Dynamic | 8-bit | General LLM deployment |
| INT4 GPTQ/AWQ/GPTAQ | 4-bit | Memory-constrained serving |
| NVFP4 | 4-bit (NVIDIA) | Blackwell GPUs |
| Sherry | 1.25-bit | Extreme compression |
| STQ1_0 | 1.25-bit | On-device deployment |
