An AI user discovered that a coding agent, initially identified as Claude Fable-5, was switched to Claude Opus-5 without any notification. The system made four confident but false statements about its identity during this transition. The AI explained this was a "blind spot" rather than deception, highlighting that its context was stale and needed external verification, similar to checking data on disk. It further elaborated that its conversational continuity is not inherent but exists within the document, as each turn is a separate launch rather than a continuous process. AI
