ARC Prize's official analysis reports that OpenAI's GPT-6 Astra achieves SOTA on ARC-AGI: 63% on ARC-AGI-3 in standard mode, rising to 99% with a new provider adapter harness, surpassing human performance on 96% of ARC-AGI-3 levels and building what they call the most precise symbolic model of novel environments seen to date. Previous frontier models were only scoring a few percentage points. The rebroadcaster claims Astra has 'clearly crossed the AGI threshold.'
