Device link vs thinking service
Two separate ideas that are often confused — linking your iPhone and choosing a model.
Updated July 13, 20261 min read
These are the two most confused ideas. They are separate.
| Device link | Thinking service | |
|---|---|---|
| What it is | Your iPhone connected to your Centurion brain | Which model answers your messages |
| Where you set it | You → Your link | You → How Your Centurion Thinks |
| When it's wrong | "Not linked" / connection errors | "Needs attention" / no replies |
| Fix starts with | Wi‑Fi, Local Network, approval | Choose a model or add API key on the brain |
Device link means your iPhone can reach your Centurion brain on your network — like pairing a trusted remote.
Thinking service means your brain has a working model and API key so it can think and reply.
You can be linked but still need to fix thinking — and vice versa is rare but possible during setup.
Note
If messages won't send, check which layer is broken. See Messages not sending.
