Key points

  • We once again got a new set of warnings yesterday, and new movement towards living in a sane world.
  • The candidate for Astra 6.1 was found to be too misaligned, including deception and exceeding scope.
  • Maxwell Zeff (WSJ): OpenAI says it is scrapping the release of its next-generation AI model [Astra 6.1] over safety concerns that researchers raised during internal testing, in one of the clearest signs so far that agent misbehavior could stymie the industry’s rapid progression.
  • The reasons for not releasing Astra 6.1 seem rather compelling.
