OpenAI begins rolling out GPT-6 Astra model

OpenAI's GPT-6 Astra, launched on September 4, 2026, advances toward AGI, scoring top on benchmarks but facing scrutiny. It ties Claude Fable 5.1 at 53 points on the Artificial Analysis Intelligence Index v4.3, leads new Terminal-Bench 4.0 and AutomationBench-AA, and matches Claude on the Coding Agent Index at less than half the cost. However, independent ARC-AGI-3 scores vary widely (17%-63% stateless vs. 99.9% with adapter), and Claude still leads in some reasoning tasks. Safety concerns persist due to reduced monitorability. NVIDIA CEO Jensen Huang declared 'AGI has arrived,' though disputed; Anthropic leads enterprise coding (54% vs. OpenAI's 21%). Astra now surpasses the human baseline on SimpleBench. OpenAI reports over one billion weekly active users, 2.5 million businesses, and plans to deploy its Jalapeño chip by year-end. The model is available in ChatGPT Work, Codex, and the API, priced at $10 per million input tokens and $50 per million output tokens. It reduces unintended outcomes by 89% and is the first to reach OpenAI's 'Critical cybersecurity capability threshold.' New enterprise plugins for Oracle Analytics, Power BI, Navan, and Avalara were launched.
