GPT-6 Astra is OpenAI's most capable model and the one its documentation now recommends by default: built for the hardest end-to-end work rather than for any single task. It carries the newest knowledge of anything in OpenAI's catalogue, cut off at the end of April 2026, against a context window slightly beyond a million tokens and a 128,000-token output ceiling. Reasoning runs across five effort levels from low through maximum — and unlike the generation below it, deliberation cannot be switched off entirely, which is a deliberate signal about what this model is for. It accepts text and images, calls functions, and works with web search, file search, and computer use.
