## About GLM-4-9B

GLM-4-9B was released in June 2024 as a downloadable 9-billion-parameter model family from Zhipu AI and the GLM team. It included base and chat checkpoints, with the standard chat model supporting a 128,000-token context window. The release offered a smaller deployment option alongside the hosted GLM-4 flagship, giving developers weights they could adapt and run themselves.

The chat model supported tool-oriented features such as function calling and code execution within a surrounding application. A separately named long-context variant, GLM-4-9B-Chat-1M, extended the family to one million tokens. Keeping those checkpoints separate avoids assigning the 1M variant's context limit to the standard model. The release also emphasized multilingual coverage beyond the earlier Chinese-English focus.
