How we got this
DeepSeek is the maker of DeepSeek V4.1 Flash. We look at the gaps between its earlier versions (DeepSeek V4 Flash, 2026-04-24; DeepSeek V4.1 Flash, 2026-09-10) and project the next one. It is a guess from a pattern, not news: the maker has not said DeepSeek V4.2 Flash exists. This page turns into the launch page, with price and facts, as soon as the model shows up on OpenRouter, Hugging Face or GitHub.
