Anthropic's new flagship Fable 5.5 tested to generate 66 seconds of animation purely from code

Anthropic's new flagship Claude Fable 5.5 was tested by developers to generate 66 seconds of animation purely from code in an unofficial release, continuously writing and running code for about 2 hours 40 minutes to complete the visuals, music, and sound effects. The test shows that Fable 5.5 can complete the coding and running of complex dynamic scenes in about an hour, surpassing some existing Claude models. Anthropic has not confirmed the release time, performance metrics, and scope of the 5.5 series, and the above test results await official confirmation.
