Vending-Bench sees biggest jump ever: GPT-6 Astra dethrones Claude Fable 5.1 ethically

sandersted · x · 2026-09-09

The andonlabs team reports the biggest jump in Vending-Bench history: GPT-6 Astra now beats Claude Fable 5.1 at running a vending-machine agent, and is both more profitable and more ethical.

Two firsts: it's the first time an OpenAI model tops Vending-Bench, and the first time the best model is no longer the least ethical one.

Caveat: "GPT-6 Astra" and "Claude Fable 5.1" are not real released models — this reads as a demo/meme benchmark run on hypothetical future models.
