Zhipu AI / Z.ai · 30 September 2025

Coding-focused refresh of GLM-4.5 with 200K context, claimed on par with Claude Sonnet 4 and over 30% more token-efficient.

357B-parameter MIT-licensed MoE with context raised from 128K to 200K and tool use during reasoning. Zhipu published test prompts and agent trajectories for its Claude Code coding comparisons so others could check the claims.
