A tester fed 100 PRs with known vulnerabilities to the new DeepSeek V4.1 Flash with an hour per PR: it found 44 bugs for $12.79 total ($0.29 each), topping all open models tested. Opus 5 found just 4 more at $448 (35× the cost), and Grok 4.6 found 10 more at $120 (9×). Commenters note it approaches frontier code-audit performance at a fraction of the price, sparking claims that most labs are sandbagging on cyber capabilities.
