Updated: 2026-05-07 (UTC)

Overview

A fast-read summary of today’s top stories touching AI models, product decisions, funding, infrastructure, and a surprise game announcement.

AI, models & governance

  • Mira Murati (ex-OpenAI CTO) testified under oath that Sam Altman lied to her about safety standards for a new AI model (Musk v. Altman trial).
  • Shivon Zilis’s courtroom testimony has become a focal point in the same trial, drawing scrutiny of internal actions and alliances.
  • Investor voices remain mixed: Barry Diller defended Sam Altman while warning AGI is unpredictable and needs guardrails.

Product pivots & commercial deals

  • Snap said its previously announced $400M integration deal with Perplexity has “amicably ended.” This affects AI search integration plans for Snapchat.
  • Google pulled the plug on Project Mariner, an experimental web-agent feature; the project’s landing page now shows a shutdown message.
  • xAI appears to be shifting emphasis toward building data centers rather than presenting itself solely as a model-training company.

Infrastructure & sustainability

  • Microsoft’s rapid AI data-center expansion is colliding with its clean-power commitments, raising questions about scale versus sustainability.

Funding & startups

  • Pronto (India) raised backing from Lachy Groom after a 20-minute pitch; reported scale is ~26,000 daily bookings as it targets a large market opportunity.
  • Corgi, an insurance startup, closed a $160M Series B led by TCV and reached a $1.3B valuation just four months after its Series A.
  • Robinhood says 150,000+ retail investors participated in its new venture fund IPO, offering retail access to private tech exposure.

Developer & consumer headlines

  • Nintendo surprise-announced the first new Star Fox game in a decade, titled simply “Star Fox,” for the Switch 2; Fox McCloud’s cameo in the Super Mario Galaxy movie had hinted at this reveal.

Key takeaways

  • Litigation and whistle testimony (Mira Murati, Shivon Zilis) are shaping public trust and governance narratives for major AI labs.
  • Big-tech product experiments (Project Mariner) can be shut down quickly; third-party integrations (Snap & Perplexity) can dissolve even after announced deals.
  • AI infrastructure growth (xAI, Microsoft) intensifies tensions between scaling compute and sustainability commitments.
  • Startup funding remains strong across verticals — transport booking, insurtech, and retail-access venture products continue to attract capital.
