Get started with OpenAI GPT-5.5, GPT-5.4 models, and Codex on Amazon Bedrock

Amazon Web Services has announced the general availability of OpenAI's latest frontier models GPT-5.5 and GPT-5.4, along with Codex coding agent, on its Amazon Bedrock platform. The integration allows enterprise customers to deploy these advanced AI models through AWS's managed inference infrastructure, which includes built-in security controls, governance features, and pay-per-token pricing models. The addition of these OpenAI models to Bedrock expands the platform's AI model portfolio, giving organizations access to some of the most advanced language models and coding capabilities available. Bedrock's managed service approach means customers can leverage these powerful AI tools without having to manage the underlying infrastructure, while benefiting from AWS's enterprise-grade security and compliance features. Codex, OpenAI's specialized coding agent, represents a significant addition for development teams looking to integrate AI-powered code generation and assistance into their workflows. The pay-per-token pricing model allows organizations to scale their AI usage based on actual consumption rather than fixed capacity commitments.
