● OpenConfidence: Low
Responses to fixed prompts no longer match this model’s own history (1344 recent vs 5906 baseline responses). Biggest shifts: whether it reasoned at all on “Give one tip for sleeping better, in one sentence.”; output length on “Give one tip for sleeping better, in one sentence.”; reasoning tokens on “Give one tip for sleeping better, in one sentence.”

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 Nov 6, 2026, 4:05 AM UTC UTC. An incident resolves on its own when the series returns to its baseline. Methodology.
