OpenAI's GPT-6 Astra on ARC-AGI-3

The ARC Prize team reports that GPT-6 Astra scored 99.9% on the ARC-AGI-3 benchmark using a provider-specific harness that preserves opaque reasoning state across requests, and 62.7% under a standard provider-neutral harness. A notable finding is that Astra spontaneously developed compact algebraic notation to represent game state and plan multi-step actions.
