GPT-6 Astra is OpenAI's flagship model for demanding end-to-end work, released on 2026-09-04. It is built for advanced analysis, software engineering, deep research, scientific work, and document creation, with particular strength on long-horizon tasks that unfold over many steps rather than a single prompt. It supports reasoning, vision, tool use, prompt caching, and web search. Context window: 1.05M tokens, output: 128K. The oversized context makes it practical to hold entire codebases or research corpora in one session, while prompt caching keeps the repeated portion affordable. Available via OpenAI and Anthropic protocols through Ofox.
