 - **Outstanding reasoning capability**: State-of-the-art performance on Math reasoning, surpassing models like Llama3 and Gemma2-9B.
 
-- **1M Context window**: Nearly perfect at finding needles in the haystack with 1M-long context, with leading performance on long-context tasks like LongBench. Try it with [LMDeploy](https://github.com/InternLM/InternLM/blob/main/chat/lmdeploy.md) for 1M-context inference.

Try it with [LMDeploy](https://github.com/InternLM/InternLM/blob/main/chat/lmdeploy.md) for 1M-context inference and a [file chat demo](https://github.com/InternLM/InternLM/tree/main/long_context).
 
 - **Stronger tool use**: InternLM2.5 supports gathering information from more than 100 web pages, corresponding implementation will be released in [Lagent](https://github.com/InternLM/lagent/tree/main) soon. InternLM2.5 has better tool utilization-related capabilities in instruction following, tool selection and reflection. See [examples](https://github.com/InternLM/InternLM/blob/main/agent/lagent.md).
 
 ## InternLM2.5-7B-Chat-1M
 
-InternLM2.5-7B-Chat-1M is the 1M-long-context version of InternLM2.5-7B-Chat. Since huggingface Transformers does not directly support inference with 1M-long context, we recommand to use LMDeploy. The conventional usage with huggingface Transformers is also shown below.
+InternLM2.5-7B-Chat-1M is the 1M-long-context version of InternLM2.5-7B-Chat. 
+
+### Performance Evaluation
+
+We employed the "*needle in a haystack approach*" to evaluate the model's ability to retrieve information from long texts. Results show that InternLM2.5-7B-Chat-1M can accurately locate key information in documents up to 1M tokens in length.

+
+We also used the [LongBench](https://github.com/THUDM/LongBench) benchmark to assess long-document comprehension capabilities. Our model achieved optimal performance in these tests.

 ### LMDeploy
 
+Since huggingface Transformers does not directly support inference with 1M-long context, we recommand to use LMDeploy. The conventional usage with huggingface Transformers is also shown below.

 LMDeploy is a toolkit for compressing, deploying, and serving LLM, developed by the MMRazor and MMDeploy teams.
 
 Here is an example of 1M-long context inference. **Note: 1M context length requires 4xA100-80G!**
