Trainable Agents is designed as a modular, extensible toolkit for rapid development and training of AI agents powered by state-of-the-art large language models. The framework abstracts core components such as interaction environments, policy interfaces, and feedback loops, enabling developers to define tasks, supply demonstrations, and implement reward functions effortlessly. With built-in support for OpenAI GPT and Anthropic Claude, the library facilitates experience replay, batch training, and performance evaluation. Trainable Agents also includes utilities for logging, metrics tracking, and exporting trained policies for deployment. Whether building conversational bots, automating workflows, or conducting research, this framework streamlines the entire lifecycle from prototyping to production in a unified Python package.
