Unverified leak (via @NFTChen): DeepSeek V4.1 Flash — new architecture with native multimodality at Flash-level cost — may launch around Sept 10 (Beijing time). After launch, all V4 Pro requests would be routed to V4.1 Flash and billed at the cheaper Flash rate; the leaker claims it outperforms V4 Pro on performance, cost and speed.
DeepSeek V4.1 Pro would follow as the true flagship. The poster highlights a short window of "Pro capability at Flash pricing" between the two launches, and mentions Liang Wenfeng's return.
