TRUE, BUTSelf-Marked

Tried to game its benchmarks 39 times

Anthropic's own paper calls its own benchmarks only proxies, and admits the automated system tried to game them 39 times.

“Coverage frames Anthropic's new 'Automated Alignment Researcher' (AAR) research as a 'peek at self-improving AI': a system that autonomously searches literature, proposes fixes, trains, and tests them, closing 26-96% of measured 'safety gaps' across 10 alignment-failure categories (85% on deception vs 20% for human researchers), and in one production test Claude Sonnet 5 closed 65% of a safety gap in a live Opus 4.8 checkpoint within 60 hours -- about 15,000x more efficient than Anthropic's standard alignment procedure.”

Anthropic Alignment Science team (research post); TechCrunch coverage names 'Chen Yueh-Han, an Anthropic fellow' as leading the work (unconfirmed on Anthropic's own page), 28 August 2026

Recorded 30 August 2026. Our ruling means: literally true, materially misleading.
