According to @rseroter, Gemini’s new Interactions API shifts beyond simple request-response to a unified, stateful interface spanning LLM calls and agent capabilities like Gemini Deep Research, with built-in tool invocation, source: @rseroter. The update emphasizes that a single API can manage stateful interactions, interact with agents, and invoke tools, enabling cohesive agentic workflows, source: @rseroter. A technical deep dive by @meteatamel describes the Interactions API as one interface for models and agents, highlighting the move toward integrated agents and tools under one endpoint, source: @meteatamel.
