About

ChatGLM-6B is the original open-source bilingual (Chinese-English) chat model from THUDM (Tsinghua University KEG Lab and Zhipu AI). Released March 13, 2023, it was pre-trained on approximately 1 trillion Chinese-English tokens using supervised fine-tuning and RLHF for alignment. With a 2K context window and 6.2B parameters, it was one of the first widely-accessible open-source LLMs with strong Chinese-language capabilities. Predecessor to ChatGLM2-6B and the ChatGLM3 family.
