OpenAI’s Navier-Stokes claim, Meta’s Muse agent, and Mistral’s mega-round

In today’s AI in Flow, Claire and Peter unpack OpenAI’s extraordinary, unverified claim that an unreleased model running up to 10,000 concurrent agents produced a proof addressing part of the Navier-Stokes Millennium Prize Problem, plus the trust and data-governance questions it raises. They also look at Meta’s new personal AI agent Muse, which asks for broad access across email, calendars, payments and health services, and what that means for privacy sentiment and the future of cross-service agents. Plus, Mistral’s reported 3 billion euro Series D at a 21 billion euro valuation and what it signals about sovereign AI in Europe, Google Cloud’s expanded partnership with Accenture to get pilots into production faster, and fresh US warnings about China-linked token extraction from frontier model APIs. Round-up items include Anthropic’s alert on stolen Claude tokens, DeepMind’s AlphaGenome Atlas, OpenAI’s ChatGPT Images 2.5, an expanded class action against Anthropic, and Google moving Chrome to a two-week release cycle.About Six & FlowSix & Flow is a digital transformation consultancy helping businesses adapt, grow, and thrive in a fast-changing world.
