GLM-5.2: Built for Long-Horizon Tasks

Z.AI introduces GLM-5.2, a model for long-horizon tasks with a solid 1M-token context, improved architecture using IndexShare, MIT open-source license, and strong benchmark performance including 81.0 on Terminal-Bench 2.1 and 62.1 on SWE-bench Pro, outperforming its predecessor GLM-5.1 and closing the gap to closed-source frontier models like Opus 4.8 and GPT-5.5 on several benchmarks.
