# Chat Models

> Available AI models for Windsurf Chat including Base Model, Windsurf Premier, GPT-4o, and Claude 3.5 Sonnet with different access levels.

While we provide and train our own dedicated models for Chat, we also give you the flexibility choose your favorites.

It's worth noting that the Windsurf models are tightly integrated with our reasoning stack, leading to better quality suggestions than external models for coding-specific tasks.
