Summary

Eliminates per-developer licensing overhead and locks you into a single cloud vendor's inference layer. Codex at scale (4M weekly users) means standardizing on AWS for code generation if you need IDE integration.

Replaces self-managed OpenAI API calls with Bedrock's managed endpoint. Requires AWS account, IAM policy updates, and SDK swap. Worth trying now if you're already on AWS; otherwise, DigitalOcean Serverless Inference offers the same models without vendor lock-in.
