Summary
Hey dear subscriber, Alex here from W&B, let me catch you up! This week started with Anthropic releasing /fast mode for Opus 4.6 , continued with ByteDance reality-shattering video model called SeeDance 2.0 , and then the open weights folks pulled up! Z.ai releasing GLM-5 , a 744B top ranking coder beast, and then today MiniMax dropping a heavily RL’d MiniMax M2.5 , showing 80.2% on SWE-bench, nearly beating Opus 4.6!

We were honored to have Lou, the Head of DevRel at Z.ai , join us live on the show at 1:00 AM Shanghai time to break down this monster of a release. GLM-5 is massive, not something you run at home (hey, that’s what W&B inference is for!) but it’…
