GLM 4.6
Z AI GLM 4.6 is an open-weight Mixture-of-Experts model built for agentic workflows, with a 200K context window, tool-use reasoning, and coding support.
Model Overview
Capabilities, design details, and architectural traits
GLM 4.6 - Agentic MoE Foundation Model
GLM 4.6 is Z.AI's (Zhipu AI) flagship Mixture-of-Experts language model positioned for agentic workflows, long-context reasoning, and real-world coding. Official materials describe it as an incremental but material step over GLM-4.5, with a larger context window and stronger practical task performance.
Distinctive Traits
- Agentic workflow focus: Official descriptions emphasize tool use, multi-step reasoning, and practical coding in agent environments.
- Long-context handling: The model extends to a 200K-token input window, with 128K maximum output tokens.
- Open-weight release: The Hugging Face card lists an MIT license, supporting commercial use and local deployment.
- Coding-agent integration: Documentation and ecosystem references mention use with Claude Code, Cline, Roo Code, and Kilo Code.
Why It Exists
GLM 4.6 is presented as a flagship release for users who need a model that can handle longer context, tool-assisted reasoning, and production coding workflows without giving up open-weight deployment options.
