Hours after Anthropic released Opus 5.5, OpenAI launched GPT-6 Sol and Luna with 50% price cuts — the AI price war is on.
Astra tops MazeBench 3D spatial reasoning with 14% and completes Valve Portal solo in 24 hours.
Same model, same test, two verified scores 37 points apart. Inside the benchmark controversy rocking OpenAI's biggest launch.
On the new FrontierMath Erdős benchmark of 68 unsolved math problems, GPT-6 Astra was the only model to score above zero — solving 5 problems while GPT-5.6 Sol, Fable 5.1, and others all scored 0%.
OpenAI launches GPT-6 Astra: 99.9% on ARC-AGI-3, 100% on ExploitBench, 47% faster computer tasks, and real math breakthroughs. But coding benchmarks are tied with Anthropic, and third-party rankings still favor Fable 5.1.
