In brief
OpenAI released GPT-6 Astra on September 3 at $10 per million input tokens and $50 per million output, 2.5 times the price of the model it replaces.
Testers with early access posted a street-by-street Manhattan in Unreal Engine, a browser-based 3D Hangzhou built in 24 minutes, a multiplayer shooter made in a day, and a Bach chorale with no voice-leading errors.
The same testers rated its writing below its own predecessor, and Artificial Analysis measured a drop of roughly 80 Elo points on a benchmark of economically valuable professional work.
OpenAI released GPT-6 Astra on September 3, and within 48 hours the developers who got early access had turned the launch into a public stress test. What they posted splits along one clean line.Astra is the strongest model anyone has used for anything spatial, mechanical, or agentic. It is also, by the account of several of the same people, a worse writer than the model it replaces.Myriad: Which companies will IPO before 2027? Click to make your prediction.The model costs $10 per million input tokens and $50 per million output tokens, a token being roughly three-quarters of a word and the unit AI companies bill by. That is 2.5 times the rate of GPT-5.6 Sol, according to Artificial Analysis. OpenAI president Greg Brockman used the launch briefing to announce the arrival of AGI.The headline feature is computer use, which means the model drives a mouse and keyboard on a real desktop instead of handing back a list of instructions for you to follow. On OSWorld 2.0, a test that scores what percentage of ordinary desktop chores an agent finishes on its own, OpenAI reported 72.6% at roughly 40 minutes per task, against 65.7% at 75 minutes for Sol.It is also the first model OpenAI has ever rated at the critical threshold for cybersecurity, meaning it can find unknown software flaws and build working attacks without a human pointing at the hole first.But beyond benchmarks, enthusiasts sharing their real use cases may be the best example to know where GPT-6 is gold and where it’s trash. Here are some of the most interesting resultsVisual Understanding: A Manhattan built street by streetTurns out, Astra is extremely good in terms of visual understanding and spatial awareness.Matt Shumer, an investor and the former CEO of HyperWrite, gave Astra a week inside Unreal Engine, the game engine behind Fortnite. In that time, Astra was able to generate a replica of Manhattan. He posted a flythrough and said the model worked "street by street to make each one perfect."
