OpenAI has announced that its GPT-5.5 and GPT-5.4 language models, alongside the Codex coding tool, are now accessible via Amazon Web Services. These models operate through Amazon Bedrock within commercial and government cloud regions, though availability is currently restricted to US-based locations. Pricing aligns with OpenAI’s standard rates without additional charges, and usage is aggregated under existing AWS contracts. Both models utilise Bedrock’s new inference engine, while Codex functions via the dedicated app, command line, and integrated development environment integrations. All requests pass through Amazon Bedrock, leveraging security measures such as identity and access management, virtual private cloud isolation, and encryption protocols.
This development matters because it offers enterprises a familiar infrastructure to access cutting-edge generative AI without managing underlying hardware or navigating complex vendor contracts. By routing traffic through established AWS security frameworks, organisations can deploy advanced models with reduced compliance friction, particularly within government sectors requiring GovCloud certification. The arrangement also allows businesses to consolidate their AI and cloud spending, potentially simplifying budgeting and operational overhead while maintaining direct access to OpenAI’s latest capabilities.
- OpenAI’s GPT-5.5, GPT-5.4 and Codex are now live on Amazon Bedrock in US commercial and GovCloud regions.
- Pricing mirrors OpenAI’s direct rates with no extra fees, counting against existing AWS spending commitments.
- Deployment benefits from AWS-native security controls including IAM, VPC isolation and end-to-end encryption.
