LemLab is a modular framework for developing AI agents powered by large language models. Developers can define custom prompt templates, chain multi-step reasoning pipelines, integrate external tools and APIs, and configure memory backends to store conversation context. It also includes evaluation suites to benchmark agent performance on defined tasks. By providing reusable components and clear abstractions for agents, tools, and memory, LemLab accelerates experimentation, debugging, and deployment of complex LLM applications within research and production environments.

Embabel Agent provides a structured approach for building AI agents in Node.js and browser environments. Developers define tools—such as HTTP fetchers, database connectors, or custom functions—and configure agent behaviors through simple JSON or JavaScript classes. The framework maintains conversation history, routes queries to the appropriate tool, and supports plugin extensions. Embabel Agent is ideal for creating chatbots with dynamic capabilities, automated assistants that interact with multiple APIs, and research prototypes that require on-the-fly orchestration of AI calls.
