OpenAI Publicly Releases GPT-6 Astra, Heralding a "Generational Leap" in AI Capabilities

OpenAI has publicly released its GPT-6 Astra model, which underpins the next iteration of ChatGPT. The company describes it as a "generational leap" in agentic and computer-use capability, with President Greg Brockman suggesting it's "not unreasonable" to consider it the start of the "AGI era." The model was released to paid users on September 4, 2026, in a restricted version that limits certain cybersecurity prompts.
