## About ChatGLM-6B

ChatGLM-6B was introduced in March 2023 as a bilingual conversational model focused on Chinese and English. Developed through the GLM research line associated with Tsinghua University and Zhipu AI, it made a relatively small assistant checkpoint available for local experimentation. The release used the General Language Model architecture rather than simply repackaging a Llama checkpoint.

Its approximately 6.2 billion parameters and support for quantization made local inference more accessible than with much larger models. The repository described running a quantized version with as little as 6 GB of GPU memory. The code and weights had separate licensing terms, so the presence of an open code repository did not by itself grant unrestricted commercial use of the model.
