Are OpenAI 5.6 models available on AWS Bedrock yet?

Check the Bedrock pricing page and AWS What's New announcements. The models weren't listed on the pricing page in the discussion, which suggests they may not have been released there yet, but it doesn't prove there isn't a limited rollout.

A support ticket or a message to your AWS account team is reasonable if you need a definite answer for your account. They may not have rollout details they can share, though, so don't count on getting an availability date.

One update cited GPT 5.5 as the latest release as of June 1, 2026. That's a dated reference, not confirmation of the current status of 5.6, so check the latest AWS announcements before drawing a conclusion.
