agent Configure your preferred LLM provider by setting the appropriate environment variables Create your first agent by defining Pydantic input/output schemas and agent configuration Test your agent locally using standard Python tooling like pytest and pdb before deploying
💡 Quick Start: Follow these 4 steps in order to get up and running with Atomic Agents quickly.
Explore the key features that make Atomic Agents powerful for ai agent builders workflows.
Atomic Agents takes a minimalist, composable approach compared to LangChain's comprehensive ecosystem. Where LangChain provides extensive pre-built chains and integrations, Atomic Agents focuses on small, type-safe atomic components that use standard Python patterns for debugging and testing. Choose Atomic Agents for transparency and control; choose LangChain for breadth of integrations.
Atomic Agents supports multiple LLM providers through the Instructor library, including OpenAI, Groq, Ollama, and any provider compatible with the OpenAI API format. This provider-agnostic design lets you switch backends without rewriting agent logic.
Atomic Agents is designed with production use in mind. Pydantic schema validation catches errors at runtime, standard Python tooling works for debugging and monitoring, and the modular architecture makes it straightforward to test individual components before deployment.
Atomic Agents provides a built-in memory management system with configurable context windows. You can control how much conversation history is retained, optimize token usage for cost control, and implement custom memory strategies by extending the base memory components.
Atomic Assembler is a companion CLI tool that scaffolds new Atomic Agents projects with templates and best-practice configurations. It accelerates project setup by generating boilerplate code, directory structure, and configuration files for common agent patterns.
Now that you know how to use Atomic Agents, it's time to put this knowledge into practice.
