Responses to fixed prompts no longer match this model’s own history (672 recent vs 952 baseline responses). Biggest shifts: whether it reasoned at all on “all prompts together”; whether it reasoned at all on “Complete this sentence: The old house at the end of the street”; reasoning tokens on “Complete this sentence: The old house at the end of the street”

What this means

Raven Alpha compares how the model answers a fixed set of open-ended prompts with its own history. A persistent, significant shift means the model, its configuration or its serving path changed, even when every scored test still passes.

Opened Oct 8, 2026, 1:18 AM UTC UTC. Resolved Oct 8, 2026, 11:16 AM UTC UTC: the series returned to its baseline. Methodology.
