OpenAI launches GPT-6 Astra and claims the AGI era has begun

OpenAI launched its new flagship model, GPT-6 Astra, on September 3, 2026. The company calls it a “generational leap in capability” across cybersecurity, professional work, software engineering, science and computer use. It is also the first model designated as meeting OpenAI's “critical cybersecurity capability threshold”.

At a press briefing, president Greg Brockman said “it's not unreasonable to feel that we are now in the AGI era.” The model rolls out first to enterprise customers on OpenAI's Daybreak cybersecurity platform, before reaching Plus, Pro, Business and Enterprise users, then the OpenAI API and AWS “in the coming days”.

A massively trained model

According to research VP Aidan Clark, it is OpenAI's largest training run to date: “the first time we've pre-trained on more than 100,000 GPUs at our Stargate site in Texas.” OpenAI touts its agentic skills (multistep tasks, building working websites, polished documents) and coding prowess, with API pricing announced at $10 per million input tokens and $50 per million output tokens.
