GPT Astra

Part of OpenAI on Models.

OpenAI's most capable line, for the most demanding work.

GPT-6 Astra is the top of OpenAI's lineup — the most capable model for the most demanding work, in OpenAI's own words. It carries a 1.05M-token context (922K max input), a 128K output window, and the highest price in the catalog at $10 in / $50 out per MTok.

What it is good at

• The most demanding work, with the deepest context at 1.05M tokens

What it is less good at

• The most expensive OpenAI line; prompts over 272k tokens double the input price
• No benchmarks published by OpenAI

Versions

One block per version, the current one first, each with its own anchor. The comparison table puts the costs and the family's benchmark columns side by side; the values are verbatim, and every one is sourced and dated in its version's section below and in the Sources list. A dash means the source publishes no figure, and nothing here is estimated.

No independent intelligence or speed index is republished here: Artificial Analysis measures both across labs, and its terms allow the link but not the copy — its figures live on its own pages.
