GLM 4.7 is a large language model from Z.ai (formerly Zhipu AI), released in December 2025 as part of the company's open-weight GLM family. It is a multilingual Mixture-of-Experts model reported at 358 billion total parameters, optimized for coding, multi-step reasoning, and tool use. The weights ship under the MIT license, and the model supports an extended context window of roughly 200K tokens.

Building directly on GLM 4.6, Z.ai positions GLM 4.7 as a more engineering-focused step forward, strengthening agentic coding, terminal-based tasks, UI generation, and stable long-horizon execution. On the provider's reported Humanity's Last Exam benchmark it scores 42.8%, a 12.4-point gain over GLM 4.6, and the model card cites improved results on the τ²-Bench tool-invocation and BrowseComp web-browsing evaluations. A central new capability is finer control over reasoning: GLM 4.7 extends the family's interleaved thinking, letting developers disable reasoning for lightweight requests and enable it for complex tasks.

The release is accompanied by a lighter variant, GLM 4.7 Flash, aimed at efficiency-balanced deployment. GLM 4.7 sits between GLM 4.6 and Z.ai's subsequent generation, including GLM 5 and the newest GLM 5.2. The open weights are distributed through Hugging Face for local serving, and the model is also available via Z.ai's API.
