Peter Yang tested Claude Fable 5.2 against Opus 5.5: Fable won four of five use cases
Peter Yang got early access to Claude Fable 5.2 and ran comparative tests against Opus 5.5 on five use cases, including a Japan travel video, a 3D kart racing game, a website redesign, writing a 600-word article with no filler, and holding its position when he raised counterarguments. Fable won four of the five rounds, while Opus still won one; which one it was requires watching his video. Claude officially announced the launch of Claude Fable 5.2 and Claude Mythos 5.2 the same day, saying both have improvements in areas such as coding, reasoning, and vision.
