Z.ai Ships GLM-5.2: Open-Weight Model Matches Opus 4.8 on Agentic Benchmarks at a Fraction of the Cost
Z.ai released GLM-5.2, a 753B open-weight model with MIT licensing that matches Anthropic's Opus 4.8 on agentic benchmarks at roughly one-fifth the token cost. The 1M-context model is already running in Cursor and Claude Code, shifting enterprise leverage toward self-hosted inference.
