GPT-6 Astra
MultimodalGPT-6 Astra is OpenAI's most capable and most aligned model, released September 2026. It is the first model designated at the Critical cybersecurity capability threshold under OpenAI's Preparedness Framework, saturating ExploitBench (100%), ARC-AGI-3 (99.9%) and FrontierMath Tier 4 (98%). Built for the hardest end-to-end work across computer use, browsing, software engineering, science and professional work, it has a 1.05M-token context window, 128K max output, text and image inputs, and reasoning effort levels from low to max. Staged GA began 2026-09-03 with Daybreak/trusted defenders first, then ChatGPT Plus/Pro/Business/Enterprise, API and AWS.
