glm-4.5GLM-4.5 is an agent-oriented MoE model from Z.ai, described with 355B total parameters and 32B activated parameters. Official docs highlight reasoning, coding, tool use, and browser-style agent abilities, with both thinking and non-thinking modes. It works well as the GLM line’s earlier agent foundation model before GLM-5.

GLM-4.5 is an open-weight text model that unifies reasoning, coding and agent capabilities with hybrid thinking modes and a 128K context.
Combines reasoning, coding and agent-oriented training in one model for multi-step problem solving and software tasks.
Offers a thinking mode for complex reasoning and an immediate-response mode for simpler workloads, allowing developers to match effort to the task.
Uses a mixture-of-experts architecture with 355B total and 32B active parameters, released under the MIT license for independent deployment.
GLM-4.5 suits software engineering agents, complex text reasoning and self-hosted development workflows that benefit from selectable thinking depth.
Plan code changes, inspect project files and carry out implementation and debugging steps across a multi-turn development task.
Analyze long technical requirements or multi-step logic problems in thinking mode and produce a reasoned textual solution.
Deploy the MIT-licensed open weights in controlled infrastructure for internal coding, reasoning or agent workloads.

Metrics sourced from Artificial Analysis
GLM-4.5: capabilities, use cases, limits, and TokenHub guidance.
GLM-4.5 is a Z.AI model for reasoning, coding, and native agent workflows.
Best for code reasoning, agent workflows and tool-heavy automation, especially when deep reasoning is the priority.
Key strength: a unified focus on reasoning, coding, and native agents.
It belongs to an older generation and may lack newer capabilities. For the latest capabilities matter, consider GLM-5.
Confirm TokenHub availability; prefer the current successor for new work.
