Deep|LLM: GPT-6 Astra Opens New Markets Beyond Coding; Scaling Laws Keep Driving Compute Demand

GPT-6 Astra marks OpenAI's first major version change since GPT-5 launched thirteen months ago. OpenAI points to three firsts to explain the new series. It is the first model pre-trained on more than 100,000 GPUs at the Stargate site in Texas, the largest training run in the company's history. It is the first in which an earlier model played a substantial role in the training process. And it is the first flagship to ship with computer use as a core capability. Released on September 3, Astra is now broadly available to paid ChatGPT users, through the API, and on Azure and Bedrock. Pricing is $10 per million input tokens and $50 per million output tokens, 2.5 times Sol and the same as Fable 5.1, with a 1.05M-token context window.
