GLM 5

GLM-5 is Zhipu AI's (Z.AI) flagship foundation model launched February 11, 2026, a 744B-parameter mixture-of-experts model with about 40B active parameters, roughly 200K context, pre-trained on 28.5T tokens using DeepSeek Sparse Attention. It centers on agentic intelligence, autonomously decomposing objectives into subtasks, with reported 77.8% on SWE-bench Verified, and was trained on domestically produced Huawei Ascend chips. Released as open weights under the MIT License. Ideal for agentic coding and multi-step tool-chaining workloads where open-weight self-hosting is desired.
