4977The optional `display` field controls whether thinking text is returned `"summarized"` or `"omitted"`. On Claude Opus 4.7 and later, the API default is `"omitted"`, so set `"summarized"` to receive thinking content in `thinking` blocks. Claude Code leaves `display` out of requests to some providers, such as Amazon Bedrock and Google Cloud's Agent Platform. On those providers, Opus 4.7 and later return empty `thinking` blocks even when you set `display` to `"summarized"`.
