OpenAI launched GPT-6 Astra, its latest flagship AI model, claiming advances in computer use, coding, cybersecurity and scientific reasoning. The model is rolling out to ChatGPT users and enterprise platforms, with API access also available. OpenAI said Astra outperformed Claude Fable 5.1 in several benchmarks but added restrictions for advanced cyber tasks.
OpenAI has officially launched GPT-6 Astra, its newest flagship model, positioning it as a major leap in computer use, coding, cybersecurity and scientific reasoning, while publishing benchmark comparisons that put it ahead of Anthropic's Claude Fable 5.1 on several fronts.
Rollout and availability
GPT-6 Astra began rolling out to a limited set of organisations, with plans to become available to all ChatGPT Plus, Pro, Business and Enterprise users over the following days, alongside access through the OpenAI API, Microsoft Azure and AWS Bedrock. The company said Astra usage would be included within existing subscription allowances, with the option to purchase additional credits, and that companies enrolled in its application-based cybersecurity programme would get access first.
Pricing
On the API, OpenAI is charging standard rates of $10 per million input tokens and $50 per million output tokens, with separate, lower rates for cached input, and a 'Fast' processing mode priced at roughly double the standard rate for about twice the speed. Independent tracking of the launch pegged this as roughly 2.5 times the promotional pricing of OpenAI's prior model, GPT-5.6 Sol, with a context window of 1,050,000 tokens and a maximum output of 128,000 tokens.
What the model can do
OpenAI describes Astra as its most intelligent and aligned model to date, saying it is state-of-the-art on computer use, browsing, software engineering, cybersecurity, science and professional work. The company said the model saturates several of its toughest internal and third-party benchmarks, including near-perfect scores on tests of advanced mathematics reasoning and simulated computer environments.
