DeepSeek has shipped V4.1-Flash twice, but a V4.1-Pro has not yet appeared

DeepSeek's own change log shows the V4.1 family arriving from the bottom up. V4.1-Flash was released on September 10, 2026, and an updated build, V4.1-Flash-1017, followed on October 17. The Pro tier has not been refreshed in that time, and the forecast leans towards the next Pro model not reaching the public by November 30. The September 10 notice did mention a Pro successor, but only in conditional terms. A temporary routing plan, it said, "will continue until V4.1-Pro launches." That is a reference to a future product, not a date. Independent reporting on October 4 reached the same practical conclusion: the models available to call were V4.1 Flash and V4 Pro 0813. DeepSeek also said it would keep serving the V4 Pro API after September 14, 2026, with billing unchanged. That reads as a company planning to leave the current Pro in place for now, though the notice does not say for how long. There is a case for Yes. DeepSeek is clearly active, and the Flash notice claimed benchmark results ahead of flagship models including V4-Pro. A Pro built on the same architecture would be a natural next step. A paper on a "super agent" was reported on November 1, but it is a technical preview, not a model release. Announcements slip, and only four weeks remain. The thing to watch is the DeepSeek API change log. A V4.1-Pro entry there would settle the matter.
