OpenAI officially released GPT-6 Astra on September 3, 2026, describing it as a generational leap in artificial intelligence capabilities. Trained on over 100,000 GPUs at the Stargate facility in Texas, Astra focuses on software engineering, scientific research, reasoning, and computer operation tasks. It can autonomously complete programming, financial modeling, and the creation of presentations and spreadsheets across multi-step, long-horizon workflows. OpenAI President Greg Brockman stated that this time, this model may be regarded as the arrival of AGI. Astra is also the first OpenAI model to reach its internal Critical cybersecurity capability threshold, having independently discovered and exploited zero-day vulnerabilities in testing. API pricing is set at USD 10 per million input tokens and USD 50 per million output tokens -- approximately 2.5 times the cost of GPT-5.6 Sol. Simultaneously, OpenAI CEO Sam Altman publicly confirmed for the first time that OpenAI will definitely build humanoid robots, marking the company's official entry into physical robotics.
