  ## Why Agent File? (Not an ML Framework or MLOps Tool)
  
  Agent File (.af) is an open *data format* for packaging the complete state of an AI agent, enabling portability and version control. It is distinct from:
  
  *   **ML Frameworks (e.g., PyTorch, TensorFlow, ONNX):** These provide libraries for building and training models. Agent File focuses on the *serialization of the agent's state*, which may include models, but also memory, tools, and prompts, for sharing and deployment.
  *   **MLOps Tools (e.g., MLflow, DVC, Weights & Biases):** These manage the lifecycle of ML models and experiments. While Agent File enables checkpointing and version control of *agent state*, it is a *format* that can be managed *by* MLOps tools, rather than being an MLOps platform itself.
