OpenAI Unveils Flagship Model GPT-6 Astra

🚀 OpenAI Unveils Flagship Model GPT-6 Astra

On September 3, 2026, the company announced the launch of GPT-6 Astra, calling it the smartest and most aligned model in the world. Reported results: FrontierMath Tier 4 v2 — 97.6%, GPQA Diamond — 96%, ExploitBench — 100%, ARC-AGI-3 — 98.6%, DeepSWE v1.1 — 74.1%.

🌍 A 100% score on ExploitBench means Astra was the first to cross a critical cybersecurity threshold in OpenAI's Preparedness Framework: the model can find unknown vulnerabilities and exploit chains without continuous human guidance — this sets a new standard for risk assessment and access.

👤 The model will first be available to enterprise partners in the Daybreak program, followed a few days later by ChatGPT Plus, Pro, Business, Enterprise, API, and AWS subscribers. Pricing: $10 per million input tokens and $50 per million output tokens, model name — gpt-6-astra.
