GPT-6 Astra, OpenAI's most capable model yet, launched this week and is now available in Ana.
Astra is built for agentic work: it operates a computer, writes and ships code, and holds up across long chains of tool calls without losing the thread. It's OpenAI's answer to Fable 5 in the same long-running, multi-step category, though early benchmarks put Fable 5.1 ahead on general reasoning.
In our early testing, we're seeing strong performance on long-running, tool-heavy tasks: agents that touch many systems in sequence and need to hold context across the whole chain.
Try it now by opening a new thread and selecting GPT-6 Astra from the model picker.
Enabling Access
