OpenAI has begun its staggered rollout of GPT-6 Astra, which president Greg Brockman calls a "generational leap" bringing the frontier into the "AGI era."
- Availability: starts Thursday with approved cybersecurity defenders in the Daybreak program; paying ChatGPT subscribers and API access follow "over the next several days."
- Official benchmarks: 97.6% on FrontierMath Tier 4 v2, 74.1% on DeepSWE v1.1, 95.9% on BenchCAD, 96% on GPQA Diamond, 100% on ExploitBench, and 98.6% on ARC-AGI-3.
- Outperforms GPT-5.6 and flagship Sol across coding, safety, and computer-use tasks; better at powering autonomous agents and generating docs/spreadsheets from local information.
- VP of research Aidan Clark: largest-ever training run, pre-trained on 100,000+ GPUs.
