GLM‑5.2 launches as the strongest open model with 1M‑token context
Z.ai released GLM-5.2, a 753B open-weight model with a 1M-token context and new IndexShare architecture that cuts FLOPs by 2.9×. On coding benchmarks it outperforms the previous GLM-5.1 and closes the gap to closed‑source leaders, hitting 81.0 on Terminal‑Bench 2.1, just four points shy of Claude Opus.
