GPT-6 Astra clears ARC-AGI-3 levels in fewer moves than the median human, pulling Chollet's AGI forecast forward

Epoch AI ranks GPT-6 Astra first at 169 points across 50-plus benchmarks while Artificial Analysis scores it 61 — level with GPT-5.6 Sol and behind Claude Fable 5.1 at 66 — so the aggregate verdict is genuinely split. The uncontested result is ARC-AGI-3, where Astra reached 62.7% at roughly $26,000 in test cost against 7.8% for Sol and 30.2% for Claude Opus 5, and solved 96% of levels in fewer moves than the median human who cleared them. Francois Chollet called the progress twice as fast as expected and moved his 2030 AGI forecast sooner, shifting the frontier contest from raw benchmark scores to sample efficiency — how little experience a model needs before it masters an unfamiliar environment.
