Developer felixrieseberg (known for nostalgic Windows apps), an engineer on Claude, reshared user @TheAlex's claim of early access to Opus 5.5, saying what he built "blew expectations clear out of the water" — including a Dark Souls-style recreation. Felixrieseberg added that seeing people create things he never imagined is the best part of working on Claude.
Note: Opus 5.5's existence is based on early-access claims, not official confirmation.
