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, 1:31 PM UTC UTC. Resolved Oct 9, 2026, 9:03 AM UTC UTC: the series returned to its baseline. Methodology.
