Gemini Interactions API changes its request and response schema

The Interactions API schema changes from outputs to steps and the output format configuration changes to response_format. The new schema became the default on May 26, 2026 and the legacy schema was removed on June 8, 2026.

Who is affected:

Code that parses Gemini Interactions API responses using the old outputs field.

Action needed:

Migrate parsing code to the steps schema using Google's migration guide.
