Community sources say DeepSeek has conceded a pretraining mistake on V4-Pro, which will be replaced by V4.1-Flash — officially releasing September 10th. Commenter teortaxesTex hopes to learn what went wrong, and optimistically reads V4.1-Flash as the intended compression of the V4 design that may actually scale this time. Unconfirmed by DeepSeek.
