A leak suggests GLM-5.5 may skip GLM-5.3 and target an August release.
Key rumored details:
- Aimed at competing with OpenAI, Anthropic, Google, and xAI
- Possibly 1T+ parameters
- Expected to stay open-weight
- Likely to keep a 1M token context window
- Built for long-running coding agents and autonomous workflows
The post frames it as an “Opus killer” / “Fable rival,” and says 5.6 or 5.7 may qualify as a “mythos class” model. The attached screenshot shows the context of the discussion around when China might reach Fable-class capability, with jietang saying “Probably Q1” to an earlier question.
