we open-sourced glm-5.1 agents could do about 20 steps by the end of last year. glm-5.1 can do 1,700 rn. autonomous work time may be the most important curve after scaling laws. glm-5.1 will be the first point on that curve that the open-source community can verify with their own

Wow, GLM-5.1 beat Opus 4.6, GPT-5.4, and Gemini 3.1 Pro on SWE-Bench Pro (58.4 vs 57.3 / 57.7 / 54.2) as an open-weight MIT-licensed model! The “open-source AI vs closed-source AI” gap is still ~6 months. [image]

This is crazy! https://z.ai/ has caught up with the SOTA models in coding with its GLM-5.1 open-weight model. This is a very big deal given that billions of $ are now spent on coding tokens! Congratulations to @Zai_org team, major achievement! [image]
