Baoyu Says Fable 5.5's Video Capability Improves but Offers Limited Gains for Ordinary Users

What happened

Fable 5.5's video capability has improved further; it really is strong, achieving this level with pure code. But for ordinary people this capability boost is limited, and I'm more looking forward to improvements in other areas. Quoted post by @chetaslua: Fable 5.5, it's over for video and image models 🤯 THIS IS PURE CODE, one-shotted this video, holy shit, how is this more beautiful than AI video models.

The story so far

Fable 5.5, an unreleased model that an author appears to have encountered in gray-scale testing, generated a video from pure code that impressed commenters, though Baoyu said on X that the gain is limited for ordinary users and that he would rather see other capabilities improve. The test used the prompt "Where did @karpathy go in 2026?" with web search and memory turned off. Chetaslua, whose post Baoyu quoted, called the result "pure code" that was "one-shotted" and said it looked more beautiful than AI video models. That is a promotional claim about the output, not a confirmed measure of quality. Baoyu's assessment is narrower: he said Fable 5.5's video capability has improved further and is genuinely strong for being achieved with pure code, but he framed the benefit to ordinary users as limited.
