GLM-5.1 sustains optimization over hundreds of rounds and thousands of tool calls by revisiting reasoning and revising strategy through repeated iteration. Unlike previous models that plateau early, it achieves structural transitions like IVF cluster probing and two-stage pipelines to shift performance frontiers. The model reaches 21.5k QPS after 600+ iterations and 6,000+ tool calls on vector database optimization tasks.written, reviewed, cited
- The model temporarily breaks the Recall constraint during exploration before adjusting to restore it after major structural transitions.
- Off-peak usage for GLM-5.1 is billed at 1× as a limited-time promotion through the end of April.

The GLM Coding Plan now supports the latest GLM-5.1 model for all users (Max, Pro, and Lite), and you can switch between models within your preferred Coding Agent. Users edit ~/.claude/settings.json or ~/.openclaw/openclaw.json to add the model, setting the Context Window Size to 200000. This currently only works with coding agents that support custom model configuration.written, reviewed, cited
- Users must uncheck the Support Images option when configuring the custom GLM-5.1 model.
- Engineers using OpenClaw must manually update the configuration after completing the provider setup.
- Agents lacking custom model settings require waiting for official support in a future release.
