OpenAI's GPT-5.5 and Codex now available on AWS Bedrock
OpenAI's GPT-5.5, GPT-5.4, and Codex are now generally available on Amazon Bedrock, AWS's platform for building production-scale AI applications. The models run on Bedrock's next-generation inference engine and are priced at OpenAI's first-party rates with no additional AWS fees. This follows an expanded partnership announcement between AWS and OpenAI made one month prior.
TL;DR
- GPT-5.5 and GPT-5.4 are now generally available on Amazon Bedrock with pricing matching OpenAI's direct rates
- Codex is available on Bedrock with pay-per-token pricing, with usage counting toward existing AWS commitments
- Models run on Bedrock's next-generation inference engine built for high performance, reliability, and security
- GPT-5.5 is positioned for multi-step tasks, agentic coding, and knowledge work requiring sustained context
Why It Matters
This availability expands where enterprises can access OpenAI's most capable models. By running on Bedrock rather than through OpenAI's API directly, organizations can integrate frontier models into AWS-native workflows and apply existing AWS commitments to their usage, simplifying procurement and cost management.
Business Impact
Enterprises using AWS can now deploy GPT-5.5 for production applications without switching platforms or managing separate vendor relationships. Codex availability on Bedrock enables software development teams to use OpenAI's coding agent while keeping compute spend within AWS commitments, potentially improving budget predictability.
Key Implications
- AWS strengthens its position as a distribution channel for frontier models, reducing direct OpenAI API dependency for AWS customers
- Organizations can now consolidate AI workloads on a single cloud platform, simplifying architecture and potentially reducing operational overhead
- Pricing parity with OpenAI's first-party rates removes cost arbitrage concerns but may limit Bedrock's competitive differentiation on price alone
What to Watch
Monitor adoption patterns among AWS customers to see whether Bedrock becomes the preferred distribution channel for OpenAI models or remains a secondary option. Watch for pricing changes or feature differentiation that AWS might introduce to justify Bedrock as a distinct offering. Track whether other cloud providers negotiate similar exclusive or preferred access to frontier models.
