DeepSeek V4.1 Flash 1017 hands-on: game and 3D gains, between Opus 5 and 5.5

A user finds V4.1 Flash 1017 much better at games and 3D modeling than the previous version, roughly between Opus 5 and 5.5, though it still overthinks with long CoT.

Used V4.1 Flash 1017 for a while. Huge jump in building games and 3D modeling over the old one, somewhere between Opus 5 and 5.5 for me. Clearly trained on a lot of game/3D data. Still overthinks though, long CoT (a bit better in DeepSeek Harness 0.2.1-rc.1). btw at this price, gooood news for game and 3D devs.
