+- **\[2023.12.10\]** We have supported Mistral AI's MoE LLM: **Mixtral-8x7B-32K**. Welcome to [MixtralKit](https://github.com/open-compass/MixtralKit) for more details about inference and evaluation. 🔥🔥🔥.
 - **\[2023.11.22\]** We have supported many API-based models, include **Baidu, ByteDance, Huawei, 360**. Welcome to [Models](https://opencompass.readthedocs.io/en/latest/user_guides/models.html) section for more details. 🔥🔥🔥.
 - **\[2023.11.20\]** Thanks [helloyongyang](https://github.com/helloyongyang) for supporting the evaluation with [LightLLM](https://github.com/ModelTC/lightllm) as backent. Welcome to [Evaluation With LightLLM](https://opencompass.readthedocs.io/en/latest/advanced_guides/evaluation_lightllm.html) for more details. 🔥🔥🔥.
 - **\[2023.11.13\]** We are delighted to announce the release of OpenCompass v0.1.8. This version enables local loading of evaluation benchmarks, thereby eliminating the need for an internet connection. Please note that with this update, **you must re-download all evaluation datasets** to ensure accurate and up-to-date results.🔥🔥🔥.
