OpenAI releases new model after reaching ‘critical’ cyber threshold

OpenAI released GPT-6 Astra on September 3, 2026, as a computer-use flagship model rather than a chat tool. It features a 1.05M-token context window and reports 72.6% on OSWorld V2-Offline. This is the first model to cross OpenAI's critical cybersecurity threshold, influencing access and usage. Initially rolled out to limited organizations, it will reach more paid users soon. The model replaces Codex compaction with searchable notes and is priced at $10/$50 per million tokens.
