DeepSeek released DeepSeek-V4.1-Flash and says it beats its larger DeepSeek-V4-Pro on performance, cost, speed, and total runtime. Starting Sept. 14, V4-Pro API requests will be served by V4.1-Flash and billed at Flash’s rates until V4.1-Pro launches, while V4-Flash and the August experimental vision model are retired. The change shifts default routing and pricing to the smaller mixture-of-experts model, with V4-Pro becoming a temporary backend rather than the billed endpoint.
Mistral announced it raised a €3 billion Series D to expand open-weight frontier AI research, training compute, and infrastructure. The funding round adds $3.5 billion (US dollars) and values the company at over €21 billion post-money. As a result, Mistral says it will keep building the full stack—models plus compute and production tools—to reduce customer dependence on a single vendor.
French investors via a pooled SPV bought into Moonshot AI, the China-based company behind the Kimi model family, ahead of its planned Hong Kong listing. The SPV put about €10 million into the last financing round, valuing Moonshot AI at a $30 billion pre-money level. This shifts capital toward open-weight model hosting in Europe and supports efforts to self-deploy Moonshot’s Kimi models with privacy-focused technologies.
