Rumored Anthropic grey-test Claude model turns code into animated clips with audio
A Chinese tech report republished by 36Kr from QuantumBit says users claim Anthropic has begun a new grey test in which Claude Opus 5.5 with High thinking may be routed to a mystery model that some call Fable 5.5 and others Opus 5.6; the model's identity has not been officially confirmed. Demos shared on social media show short animated scenes and a musical-style introduction generated largely from JavaScript code with synchronized visuals and sound, with one creator saying Suno and ElevenLabs were used for music and vocals while prompts, time and cost for the musical clip were not disclosed. One roughly 30-second "life" animation was said to take two prompts and about 27 million tokens over two hours, and some users reported little difference from regular Opus 5.5.
The report argues coding-model output is expanding from functional demos to complete visual works with camera, lighting and sound, though the model's identity and the demos' cost remain unverified.
Opus 5.5 High疑似被路由到新模型？
最近有网友爆出，Anthropic开始了新一波灰测：Opus 5.5 High可能会被路由到Fable 5.5或Opus 5.6。
不少网友展示了这款神秘新模型做出的视频。它能用很少的提示词，做出带光影变化、镜头切换和音效的动画短片：
甚至做了一部音乐剧，用来自我介绍：
听完我只能说，真的太强了，简直是《汉密尔顿》再世。
音乐、人声和3D画面都安排上了，音画同步，完成度也很高。
