GPT-6 Astra System Card - OpenAI Deployment Safety Hub


OpenAI released GPT-6 Astra on September 3, 2026. Touted by executives as the beginning of the "AGI era," this powerful new model features advanced computer-use capabilities and highly sophisticated, self-governing cybersecurity functions. [1, 2]

OpenAI is using a staggered release strategy to manage compute demands and ensure system safety:
  • Immediate Access: The model is currently available to select enterprise clients enrolled in OpenAI's cybersecurity-focused Daybreak program.
  • Upcoming Access: It is scheduled to roll out to all ChatGPT Plus, Pro, and Enterprise subscribers, alongside availability via the OpenAI API and Amazon Web Services (AWS), "in the coming days". [2]
Key Capabilities and Tech Specs
  • Autonomous Computer Use: According to Fortune, GPT-6 Astra is designed to operate software, complete complex multi-step tasks across different applications, and write or test code with minimized human intervention.
  • Massive Scale: The model marks OpenAI's largest pre-training run to date, utilizing over 100,000 GPUs at its Texas Stargate data center. It is also the company's first flagship model where older models heavily supervised the training process.
  • Critical Cybersecurity Threshold: Reports from VentureBeat note that Astra is the first model to cross OpenAI's internal "critical cybersecurity threshold," meaning it can actively identify and fix zero-day security vulnerabilities. Due to these dual-use risks, its most advanced cyber capabilities remain strictly limited to trusted defenders. [6, 7]
API Pricing
For developers using the model name, standard pricing is structured around a "price-per-task" economic outlook:
  • Input Tokens: $10 per million tokens
  • Output Tokens: $50 per million tokens
  • Fast Mode: Offers up to 2.5× faster processing at 2× the standard token pricing. [8]
