Requirements
Device tier
webAI reads your Mac’s installed memory and assigns a Device tier. That tier sets which features start on, which local model fits, and how large a context window Chat can use. Open Settings → System to see yours as Device tier.- Tier 1 starts Chat at a 10K context and can grow to 32K. Knowledge-base retrieval starts off so those models do not load into memory.
- Tier 2 and Tier 3 start at a 32K context and can grow to 128K. Tier 3 and above also get Array.
- Tier 4 starts at a 128K context.

Other paths can send work off your device, such as a connected Persona on someone else's device, a cloud model on your own API key, or a tool that reaches an outside service. See the Privacy Policy for how that data is handled.
