Pros
- +PyTorch-inspired design makes agent workflows intuitive for ML practitioners familiar with neural network concepts
- +Built-in memory management automatically handles message storage and state persistence across agent interactions
- +Lightweight architecture with clean abstractions that simplify multi-agent system development and reduce boilerplate code
Cons
- -Limited to source installation only, which may complicate deployment in production environments
- -Documentation appears minimal based on available information, potentially creating barriers for new users
Use Cases
