What changed

OpenAI released GPT-6 Astra on September 3, 2026, presenting it as a model designed to operate computers rather than mainly hold conversations. It includes a context window for processing up to 1.05 million text units, scored 72.6% on an OSWorld V2-Offline test, and uses searchable notes instead of Codex compaction.

What this means for you

Astra may help eligible users automate computer-based tasks, but access and permitted uses are limited by OpenAI’s “Critical” cybersecurity classification. Its listed price is $10 for input and $50 for output per million text units processed.
