 ## Introduction
+The second generation of the InternLM model, InternLM2, includes models at two scales: 7B and 20B. For the convenience of users and researchers, we have open-sourced four versions of each scale of the model, which are:
 
-InternLM has open-sourced a 7 billion parameter base model tailored for practical scenarios. The model has the following characteristics:
-- It leverages trillions of high-quality tokens for training to establish a powerful knowledge base.
-- It provides a versatile toolset for users to flexibly build their own workflows.
+- internlm2-base: A high-quality and highly adaptable model base, serving as an excellent starting point for deep domain adaptation.
+- internlm2 (**recommended**): Built upon the internlm2-base, this version has been enhanced in multiple capability directions. It shows outstanding performance in evaluations while maintaining robust general language abilities, making it our recommended choice for most applications.
+- internlm2-sft: Based on the Base model, it undergoes supervised human alignment training.
+- internlm2-chat (**recommended**): Optimized for conversational interaction on top of the internlm2-sft through RLHF, it excels in instruction adherence, empathetic chatting, and tool invocation.
 
-## InternLM-7B
+The base model of InternLM2 has the following technical features:
+
+- Effective support for ultra-long contexts of up to 200,000 characters: The model nearly perfectly achieves "finding a needle in a haystack" in long inputs of 200,000 characters. It also leads among open-source models in performance on long-text tasks such as LongBench and L-Eval.
+- Comprehensive performance enhancement: Compared to the previous generation model, it shows significant improvements in various capabilities, including reasoning, mathematics, and coding.

 ### Performance Evaluation
 
-We conducted a comprehensive evaluation of InternLM using the open-source evaluation tool [OpenCompass](https://github.com/internLM/OpenCompass/). The evaluation covered five dimensions of capabilities: disciplinary competence, language competence, knowledge competence, inference competence, and comprehension competence. Here are some of the evaluation results, and you can visit the [OpenCompass leaderboard](https://opencompass.org.cn/rank) for more evaluation results.

 **Limitations:** Although we have made efforts to ensure the safety of the model during the training process and to encourage the model to generate text that complies with ethical and legal requirements, the model may still produce unexpected outputs due to its size and probabilistic generation paradigm.
