Introducing GLM-5 from Z.AI
We are excited to announce that ChatBotKit now supports GLM-5, Z.AI's fifth-generation flagship open-source foundation model and their most ambitious release to date. GLM-5 is immediately available across the full ChatBotKit platform, including bots, blueprints, skillsets, and the API.
GLM-5 is built on a Mixture-of-Experts architecture with 744 billion total parameters and 40 billion active parameters per inference pass. This design gives GLM-5 an exceptional capability-to-efficiency ratio - delivering frontier-level reasoning and generation quality while keeping compute costs practical for real-world deployments. The model carries a 202,800-token context window, enabling it to process and reason over entire codebases, lengthy documentation sets, and multi-document research tasks in a single pass.
Where GLM-5 stands out most is in long-horizon agentic planning. The model was engineered from the ground up for complex systems design and multi-step autonomous task execution. Its advanced agentic planning capabilities, combined with deep backend reasoning and iterative self-correction, make it a strong choice for workflows that require persistent progress across many sequential steps - exactly the kind of tasks that challenge less specialized models.
For developers and technical teams, GLM-5 delivers production-grade performance on large-scale programming challenges. It excels at understanding intricate codebases, implementing non-trivial architectural changes, debugging deeply nested logic, and synthesizing solutions that span multiple systems. Its iterative self-correction mechanism means it can identify and recover from intermediate mistakes rather than compounding them, improving reliability on the most demanding engineering work.
GLM-5 supports function calling, enabling seamless integration with external APIs and tools within ChatBotKit Skillsets and Blueprint-based agent architectures. Whether you are building an autonomous research assistant, a large-scale code generation pipeline, or a multi-step reasoning agent, GLM-5 provides the depth and sustained coherence to handle it reliably.
To start using GLM-5, select it from the model picker in your ChatBotKit dashboard or reference it directly through the API.
