mark_k · x · 2026-10-17
An unreleased Claude model, "claude-onigiri-eap-2", has been spotted in Artificial Analysis's website code by Lumina. It appears with four reasoning levels (low, medium, high, xhigh) plus an Opus 4.8 fallback.
Separately, leaker Lyra claims Anthropic's partners already have access to "Fable 5.5" for testing, suggesting a release may be near. Anthropic has announced nothing; whether Onigiri is Fable 5.5 and the rumored launch dates remain unconfirmed.
