So, if I've got this correct there's:

1. On-device AI

2. AI using Apple's servers

3. AI using ChatGPT/OpenAI's services (and others in the future)

Number 1 will pass to number 2 if it thinks it requires the extra processing power, but number 3 will only be invoked with explicit user permission.

[Edit: As pointed out below, other providers will be coming eventually.]
