OpenAI released GPT-6 Astra, its most capable model, topping benchmarks in math, coding, and cybersecurity. President Greg Brockman said it marks the start of the "AGI era." It is the first model rated "critical" under OpenAI's safety framework and independently found two unknown zero-day vulnerabilities during testing.
GPT-6 Astra scored 98.6% on the ARC-AGI-3 benchmark, up from GPT-5.6 Sol's 7.8%. Humans navigated the interactive settings in March while frontier models scored under 1%. The benchmark tests uncharted interactive territory, not training-data recall.
