Developers think Anthropic's next top model is only days away.

Developers think Anthropic's next top model is only days away.

Anthropic has not confirmed a model called Claude Fable 5.5, and these reports are unverified. An entry for it appeared in an open-source price list on October 13 and was removed a day later. Leak trackers say partners already test it and expect a launch this week.

Why it mattersFable is Anthropic's most capable model line, so a new version would reset the bar for coding tools. If nothing ships by next week, treat the leaked codenames as noise.
