Opus 5.2 rumor prompt works only in Claude Code, not on web or app
CtrlAltDwayne · x · 2026-09-15
- An X user tested a circulating rumor prompt about Opus 5.2 and found it only behaves as claimed inside Claude Code; the Claude web and desktop apps deny knowing the referenced figure.
- The author initially assumed the rumor was false since Opus's knowledge cutoff (reportedly May 2026) should cover it, but real-world testing revealed divergent behavior across Claude entry points.
- The rumor remains unverified; treat accordingly.
