On April 7, 2026, Z.ai (formerly Zhipu) released GLM-5.1, scoring 58.4 on SWE-bench Pro — past GPT-5.4. The same week, Google moved Gemma 4 to Apache 2.0. Read them together and the real story isn't who beat whom on a leaderboard. It's that open-source capability AND licensing just shifted at the same time.
As of March 28, 2026, Zhipu’s official release notes clearly list GLM-5 on February 12 and GLM-5-Turbo on March 15. At the same time, its developer docs already position GLM-5.1 as the latest model inside Coding Agent workflows. That mismatch is the story: Zhipu is shifting the value of its models from one-shot code generation toward agent engineering, long task chains, and tool-heavy work.
