 - **Efficient RL reasoning with MTP and CoT compression.** During RL, Intern-S2-Preview adopts shared-weight MTP with KL loss to reduce the mismatch between training and inference behavior, substantially improving MTP accept rate and token generation speed. It also introduces CoT compression techniques to shorten responses while preserving strong reasoning capability, achieving improvements in both performance and efficiency.

+### Time Series Demo
+
+Time series inference is currently only supported in LMDeploy. To get started, download and deploy Intern-S2-Preview with LMDeploy by following the [Model Deployment Guide](./deployment_guide.md).
+Below is an example of detecting earthquake events from a time series signal file. Additional data types and functionalities are also supported.
+
+**Please note**: this demo is slightly different from the one in [Intern-S1-Pro](https://huggingface.co/internlm/Intern-S1-Pro#time-series-demo). The main difference is that in the messages content, you need to provide time_series_url first, followed by the text prompt. Please adapt your implementation based on this demo.

 ## Agent Integration
 
 Intern-S2-Preview can be plugged into agent frameworks in two ways: connecting to a **self-hosted deployment**, or calling the **official InternLM API**. Below we cover both, with examples for agent frameworks (OpenClaw, Hermes, etc.) and for Claude Code.
