OpenAI’s GPT-6 Astra is now generally available on Amazon Bedrock, giving AWS customers access to the company’s latest model through Amazon’s cloud platform and its existing enterprise controls.
Amazon announced the availability on September 8, 2026, describing GPT-6 Astra as OpenAI’s most capable model to date. The model is designed to provide deeper reasoning and stronger judgment for complex business tasks, including work involving software, files and multi-step workflows.
According to Amazon, organizations can use GPT-6 Astra to support AI agents that write code, analyse data and automate complex business processes at production scale. The model can also produce professional-quality outputs aligned with an organisation’s established voice, templates and standards.
Astra can be accessed through Amazon Bedrock APIs, while customers can also configure ChatGPT Work and Codex to use the model through Bedrock. Amazon said the model can continue workflows across applications through software interfaces when an API or connector is unavailable.
The availability also comes with enterprise data protections. Amazon stated that inference data from GPT-6 Astra is not used for model training, and customers do not need to opt into sharing their data with OpenAI.
GPT-6 Astra builds on Amazon and OpenAI’s broader partnership announced earlier in 2026. Through Amazon Bedrock, customers can access OpenAI models alongside offerings from other major AI providers through a common service with unified security, governance and cost controls.
OpenAI models on Bedrock inherit enterprise capabilities including IAM-based access management, AWS PrivateLink, encryption, guardrails and AWS CloudTrail logging. Customers can also apply OpenAI model usage toward existing AWS cloud commitments.
The latest launch follows the July availability of OpenAI’s GPT-5.6 family on Bedrock and the August introduction of specialised OpenAI cybersecurity models for eligible customers.
Amazon said the expanded collaboration with OpenAI is intended to continue bringing new advances in reasoning and agentic AI capabilities to Amazon Bedrock.
