GPT-6 Astra
GPT-6 Astra is OpenAI's frontier model for complex reasoning, coding, computer use, research, and document creation. It combines a 1,050,000-token context window with up to 128,000 output tokens, image understanding, structured outputs, function calling, and broad tool support. Configurable reasoning from low through max makes it well suited to long-running agent workflows that must plan, execute, and verify work across code, browsers, and professional software.
GPT-6 Astra is served through Runware's compatible endpoints, which take another provider's request format. Point the SDK you already use at Runware by changing the base URL and the API key, and set model to openai:gpt@6-astra.
Requests and responses keep the provider's format, so its reference documents every parameter.
