Amazon Bedrock now supports the reasoning.summary parameter for OpenAI models. The feature returns a readable summary of the model’s thought process together with its answer. It works for all OpenAI models in every AWS Region where they are offered, including in‑Region and cross‑Region inference. The summary appears in the summary array of the reasoning output item.
Why it matters
Developers can see why a model gave a particular answer, making debugging and user transparency easier.
