OpenAI Releases GPT-6 Astra: A 1.05M-Context Computer-Use Model Gated Behind a ‘Critical’ Cyber Threshold

OpenAI released a new model designed primarily to operate software by performing multi-step tasks across browsers, spreadsheets, applications, and terminals rather than simply describing how to complete them. The model handles context differently than previous versions by keeping detailed notes across long conversations instead of summarizing and discarding information, which allows it to retain details about failed fixes and earlier requirements. Access to the model is restricted to organizations in OpenAI's trusted programs because it has demonstrated cybersecurity capabilities classified as "critical," including the ability to discover exploits for hardened systems, and standard users face limitations on accessing advanced cybersecurity work. The model has a 1.05-million-token context window and costs $10 per million input tokens and $50 per million output tokens.
