Module: LLM::ActiveRecord::ActsAsLLM

Defined in:
lib/llm/active_record/acts_as_llm.rb

Overview

ActiveRecord integration for persisting LLM::Context state.

This wrapper maps model columns onto provider selection, model selection, usage accounting, and serialized context data while leaving application- specific concerns such as credentials, associations, and UI shaping to the host app.

Context state can be stored as a JSON string (format: :string, the default) or as a structured object (format: :json / :jsonb) for databases such as PostgreSQL that can persist JSON natively. :json and :jsonb expect a real JSON column type with ActiveRecord handling JSON typecasting for the model. provider:, context:, and tracer: can also be configured as symbols that are called on the model.
