Is Claude Opus 5.5 alright? User flags sloppy behavior over unknown tools and API names
JeremyNguyenPhD · x · 2026-11-02
JeremyNguyenPhD questions whether Claude Opus 5.5 is behaving normally: a screenshot shows the model admitting it can't place "jev" (tool or model name?) and can't find an "OpenAI decisions API," asking for clarification before proceeding. The author says this doesn't feel like the thoroughness he associates with Opus 5.5. Note: the "Opus 5.5" name itself is unverified — this is a user-side behavior observation.
