# InternLM2.5-20B Model Card
|
|
|
|
## Introduction
|
|
|
|
InternLM2.5, the 2.5th generation InternLM, has open-sourced a 20 billion parameter base model and a chat model tailored for practical scenarios. For the convenience of users and researchers, we have open-sourced two versions of each scale of the model, which are:
|
|
|
|
- InternLM2.5-20B: Further pretrain with general domain data and domain-enhanced corpus, obtaining state-of-the-art performance in evaluation with good language capability. InternLM2.5 models are recommended for consideration in most applications.
|
|
- InternLM2.5-chat-20B: Further aligned on top of InternLM2.5 through supervised fine-tuning (SFT) and online RLHF. InternLM2.5-Chat exhibits better instruction following, chat experience, and function calling, which is recommended for downstream applications.
|
|
|
|
The model has the following characteristics:
|
|
|
|
- **Outstanding reasoning capability**: State-of-the-art performance on Math reasoning, surpassing models like Llama3 and Gemma2-27B.
|
|
|
|
- **Stronger tool use**: InternLM2.5 supports gathering information from more than 100 web pages, corresponding implementation has be released in [MindSearch](https://github.com/InternLM/MindSearch). 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).
