Deepseek really just dropped a new flash model on a saturday 😭 v4.1 flash 1017 is out and the weights are free > 77 on deepswe, beats opus 5 there > 42.3 on terminal bench, still behind opus > 1M context > MIT license, anyone can download it > already live on the deepseek app and web same flash price, way better numbers. the open models keep getting closer and closer to the paid ones Soon gonna try it on a real coding task and see if it still overthinks
