About

ChatGLM2-6B is the second-generation 6B open-source bilingual (Chinese-English) chat model from THUDM (Tsinghua University / Zhipu AI). Released June 25, 2023, it improved significantly over the original ChatGLM-6B: extended context to 32K tokens via FlashAttention, trained on 1.4T tokens (up from ~1T), and achieved approximately 23% better MMLU scores. Widely used as a Chinese-language LLM baseline. Succeeded by ChatGLM3-6B in October 2023.

ChatGLM2-6B is an open-source model in the ChatGLM2 family. The structured metadata tracks a 32k-token context window. Headline tracked benchmarks include GAOKAO 42.7.
