Just like Action Mailer for emails, Active Agent uses familiar conventions to manage AI agents, prompts, & actions with minimal setup—making AI in Rails as simple as sending & receiving email. Active Agent includes these modules & features:
Action Prompt
Action Prompt defines actions that can be performed by agents and can render prompts and generative UI, making it easy to craft agent interactions using familiar Rails development patterns.
Generation Provider
The Generation Provider is a common interface to interact with AI services like OpenAI and Anthropic to generate text, images, embeddings, or speech.
Queued Generation
Queued Generation manages asynchronous tasks by handling prompt generation and response cycles with Generation Jobs, ensuring smooth, scalable AI interactions.
Callbacks
Provides hooks to execute custom code at specific points in the agent's workflow.
Streaming
Enables dynamic UI updates based on user & agent interactions.
Solid Agent
Provides Active Record models to store your agent interactions & context. (COMING SOON)

Active Agent works seamlessly with tools like Langchain Ruby, pgvector, and the neighbors gem. Its agent-based architecture handles tool calls, renders prompts, and generates vector embeddings for pgvector with ease.
