## FAQ

### How is pydantic-deep different from LangChain?

pydantic-deep is built on Pydantic AI, which provides:

- Type-safe agents with Pydantic models
- Simpler, more pythonic API
- Better IDE support and autocomplete
- No complex chain abstractions

### Can I use models other than Anthropic?

Yes! Pydantic AI supports multiple providers:

```python
# OpenAI
agent = create_deep_agent(model="openai:gpt-4.1")

# Google
agent = create_deep_agent(model="google:gemini-1.5-pro")

# Anthropic (default)
agent = create_deep_agent(model="anthropic:claude-sonnet-4-6")
```

### How do I run without API calls (for testing)?

Use `TestModel` from Pydantic AI:

```python
from pydantic_ai.models.test import TestModel

agent = create_deep_agent(model=TestModel())
```

### Can I use pydantic-deep with async frameworks?

Yes! pydantic-deep is fully async-native:

```python
from fastapi import FastAPI
from pydantic_deep import create_deep_agent, DeepAgentDeps, StateBackend

app = FastAPI()
agent = create_deep_agent()

@app.post("/chat")
async def chat(prompt: str):
    deps = DeepAgentDeps(backend=StateBackend())
    result = await agent.run(prompt, deps=deps)
    return {"response": result.output}
```

### How do I persist files between runs?

Use `LocalBackend` instead of `StateBackend`:

```python
from pydantic_ai_backends import LocalBackend

backend = LocalBackend("/path/to/workspace")
deps = DeepAgentDeps(backend=backend)
```
