Anthropic officially released Claude Fable 5.2 and Claude Mythos 5.2, targeting the most daunting technical challenges with gains in coding, reasoning, and vision. Dan Shipper of Every said his team mistook it for 5.5 during testing: members built Everycut (a video editor combining Premiere/Descript features with a built-in agent, live in 3 days), games for their kids, and documentaries instead of slide decks.
