-- **December 4, 2025:** 🚀 We support GGUF format model inference. We support Cambricon MLU590 and MetaX C500 deployment.
+- **December 4, 2025:** 🚀 Supported GGUF format model inference & deployment on Cambricon MLU590/MetaX C500.
 
 - **November 24, 2025:** 🚀 We released 4-step distilled models for HunyuanVideo-1.5! These models enable **ultra-fast 4-step inference** without CFG requirements, achieving approximately **25x speedup** compared to standard 50-step inference. Both base and FP8 quantized versions are now available: [Hy1.5-Distill-Models](https://huggingface.co/lightx2v/Hy1.5-Distill-Models).
