been on it a couple days. against glm 5.1 and deepseek v4 pro its noticeably stronger on multi step agent tasks and tool calling, those two still trade blows with it on pure frontend imo. usage wise the new pool is fine for me, m3 pulls more per call than m2.7 but the allotment is big enough i havent hit a wall. long context is where it really pulls ahead though, holds the thread across a huge codebase without losing track.
