ChatGLM-6B
The 6.2B bilingual chat model that kicked off China's open LLM wave.
About
ChatGLM-6B is an open bilingual language model from Tsinghua's THUDM team and Zhipu AI, released in March 2023. Built on the GLM framework with 6.2 billion parameters, it was trained on about 1T tokens of Chinese and English text with supervised fine-tuning and RLHF, optimized for Chinese question answering and dialogue.
Its headline feature was INT4 quantization that let it run on a single consumer GPU with just 6GB of memory, which made it one of the first widely self-hosted chat models in China. The license grants use for non-commercial research only, so commercial deployments need separate permission.
