Gemini API Interactions API becomes default; generateContent marked legacy.
Google's Gemini API documentation now states the Interactions API 'has become our default interface as of June 2026' and that developers starting new projects should use it, while explicitly marking the prior generateContent endpoint as 'legacy.' New migration guide (generateContent → Interactions) and streaming docs for real-time tokens, incremental thoughts, and tool-call events were added alongside.
