Interactions API
Also written: Messages API
An API for managing back-and-forth conversations with AI models, simplifying complex interactions.
The Interactions API is a tool that helps developers build applications where users can have conversations with AI models. Think of it like a special chat interface for AI that makes it easier for programs to send messages to the AI and get responses back.
This API is useful for creating things like chatbots, virtual assistants, or even tools that edit videos using text commands. It helps manage the flow of conversation, keeping track of what's been said so the AI can respond more contextually.
The Interactions API is an Application Programming Interface designed to streamline and manage multi-turn conversational exchanges and complex sequences of AI model inputs and outputs. It provides developers with a structured way to handle the state and flow of interactions, abstracting away much of the complexity involved in maintaining context across multiple turns.
This API simplifies the process of building conversational AI experiences by offering methods for sending prompts, receiving responses, and managing conversation history. It is crucial for applications requiring coherent, context-aware dialogue, such as chatbots, virtual assistants, and interactive content generation tools.
Google Gemini is updating its developer tools, including the Interactions API, to make it easier for programmers to build applications that use AI for conversations and multimodal tasks. This focus on simplifying developer experience for complex AI interactions is a key trend in frontier AI labs.

- Anthropic Claude
- Anthropic uses APIs that allow developers to interact with its language models, often for conversational AI.
- Google Gemini
- Google Gemini has updated its API, referred to as the Interactions API or Messages API, to streamline how developers build applications that handle conversational and multimodal AI tasks.
The concept of an Interactions API is a natural evolution in how developers interface with AI models, moving beyond simple request-response to manage more complex, stateful conversational flows. Specific implementations are often product-specific, emerging from AI labs to simplify the integration of their models into applications.
You can explore the Gemini API Cookbook on Google's developer site. Look for examples demonstrating conversational flows or multi-turn interactions to see how the Interactions API is used to manage dialogue and context in real applications.

Questions people ask
- What is the main benefit of using an Interactions API?
- It simplifies building applications that have back-and-forth conversations with AI, making it easier to manage context and user experience.
- Is the Interactions API specific to one AI model?
- While the term can be general, specific implementations like Google's are tied to their respective AI platforms, but the underlying concept applies broadly.
