OpenAI released GPT-6 Astra, its next flagship model, after a training run that used more than 100,000 GPUs at the Stargate data center in Texas. President Greg Brockman described the model as a “generational leap” and said it could signal the arrival of artificial general intelligence. The launch is initially limited to customers in OpenAI’s Daybreak program.
