Claude Sonnet 5.5 · Sekiro main menu
The episode says the GPT models use an image-generation shortcut while Claude builds the scene in-engine, and that this is why the cost and time differ. Opus max is partial: 4h 14m 39.541s and $93.87 deduplicated API-equivalent, with the contestant visual review failed. A later high-effort Opus attempt is complete at 46m 30s and $11.17 and stays related, because the large cost gap matches the max run. Sol is $1.57 with verdict QUALIFIED. Sonnet is partial_user_stopped at $70.13. Supplied source capture Unaided model Open this round
