Overview
- Google released the Interactions API in public beta via Google AI Studio, with the Gemini Deep Research agent available in developer preview.
- The API consolidates interactions at a single /interactions endpoint with optional server-side state, background execution, a composable history schema, and remote MCP tool support.
- Deep Research runs on Gemini 3 Pro for long-horizon web research, planning queries, iterating searches, and synthesizing structured, citeable reports.
- Google open-sourced the DeepSearchQA benchmark of 900 multi-step "causal chain" tasks to measure agent comprehensiveness and retrieval recall.
- Google reports state-of-the-art scores for Deep Research—46.4% on HLE, 66.1% on DeepSearchQA, 59.2% on BrowseComp—and says consumer and Vertex AI integrations are coming, with generateContent still recommended for standard production use while the new API is in beta.
