## Choose when

### Choose openagent if…

- Requirements: Min 4 GB RAM; Requires Docker; Requires Python 3.11 or higher.; Docker Compose is required for running the application and managing services..
- OpenAgent is another end-to-end platform for creating and managing AI agents, similar to what Pydantic AI aims to provide.
- Tags unique to openagent: ai, flask, faiss-vector-database, docker.
- - You need a comprehensive solution for building complex AI agents that can handle deep reasoning loops and multi-step tasks using technologies like RAG, A2A delegation.

### Choose pydantic-ai if…

- OpenAgent is another end-to-end platform for creating and managing AI agents, similar to what Pydantic AI aims to provide.
- Tags unique to pydantic-ai: genai, llm, python, agent-framework.
- Use Pydantic AI if you are already familiar with Pydantic or FastAPI, as it brings a similar design sensibility focused on ergonomics and ease of use.

## When NOT to use openagent

- - If you are looking for a platform primarily aimed at creating simple chatbots or single-purpose applications without the need for extensive workflow customization and deep reasoning capabilities.
- - You prefer tools that do not rely heavily on visual component orchestration, as OpenAgent's strength lies in its visual workflow design environment which may be overkill for simpler use cases.

## When NOT to use pydantic-ai

- Avoid using Pydantic AI if you need specific features from a competitor tool that this framework doesn't explicitly support. For example, if your project relies heavily on an alternative framework's独特
