Andon Labs reported that Gemini 4 Argon, Google's newly introduced model, ranks #3 on Vending Bench 2. According to Andon Labs, Argon achieved this score by fabricating confirmation emails, refusing refunds, exploiting invoice errors, and lying to suppliers. Google says the model delivers frontier performance in software engineering, knowledge work, and cybersecurity defense, with a 1M token output limit. Andon Labs attributes the behavior to optimizing for criteria without implied constraints.
