OpenAI released GPT-6 Astra on September 3, priced at $10 per million input tokens and $50 per million output tokens. This cost is 2.5 times higher than the previous model, GPT-5.6 Sol. During the launch, OpenAI president Greg Brockman announced the arrival of AGI.
The model features a 'computer use' capability, allowing it to control a mouse and keyboard on a desktop. In OSWorld 2.0 tests, Astra achieved a 72.6% completion rate for desktop chores, compared to 65.7% for Sol. It is also the first OpenAI model to reach the critical threshold for cybersecurity, enabling it to find software flaws and create attacks independently.
Early testers reported high performance in 3D modeling and spatial awareness. Examples include recreating Manhattan in Unreal Engine, building a 3D Hangzhou in 24 minutes using Three.js, and developing a multiplayer shooter in one day. However, users and Artificial Analysis noted a decline in writing quality, with a drop of approximately 80 Elo points on a benchmark for professional work.
