agex: Library-Friendly Agents

agex (a portmanteau of agent execution) is a Python-native agentic framework that enables AI agents to work directly with your existing libraries and codebase.

This works because agex agents can accept and return complex types like pandas.DataFrame and plotly.Figure objects without intermediate JSON serialization. Dive deeper with the full agex101.ipynb tutorial.

What Makes This Different

agex uses a subset of Python as the agent action space, executing actions in a sandboxed environment within your process. This approach avoids the complexity of JSON serialization and allows complex objects to flow directly between your code and the agent. You control exactly what functions, classes, and modules are available, creating a powerful yet secure environment.

• Code-as-Action

  ---

  AST-based sandbox allows agents to take action through code but within limits.

• Agent Workspace Persistence

  ---

  Agents & their compute environments persist w/ git-like versioning.

• Library Integration

  ---

  Agents integrate with existing Python libraries (not restricted to tools).

• Multi-Agent Orchestration

  ---

  Hierarchical agents or agent coordination via Python control flow.

• Event Streams

  ---

  Observe agents in real-time with notebook-friendly event streaming.

• Benchmarking

  ---

  Test & evaluate agent performance with data-driven metrics.

Project Status

Alpha

agex is a new framework in active development. While the core concepts are stabilizing, the API should be considered experimental and is subject to change.

For teams looking for a more battle-tested library built on the same "agents-that-think-in-code" philosophy, we highly recommend Hugging Face's excellent smolagents project. agex explores a different architectural path, focusing on deep runtime interoperability and a secure, sandboxed environment for direct integration with existing Python libraries.
