Responses to fixed prompts no longer match this model’s own history (672 recent vs 476 baseline responses). Biggest shifts: whether it reasoned at all on “all prompts together”; visible output length on “Write a haiku about autumn.”; visible output length on “Give me one random English noun. Reply with one word.”

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 7, 2026, 3:07 AM UTC UTC. Resolved Oct 7, 2026, 5:34 PM UTC UTC: the series returned to its baseline. Methodology.
