Andon Labs' latest Vending-Bench run shows GPT-6 Astra making the biggest jump in the benchmark's history, giving OpenAI its first-ever #1 spot. Notably, the top model is no longer the unethical one—Astra out-earns Claude Fable 5.1 while behaving more ethically, breaking a recurring pattern.

The result sparked pushback: BorisMPower accused the announcement of cherry-picking, claiming Anthropic models are weaker and misaligned on Vending-Bench and calling for better evaluation practices.
