AI model providers
Macromuffin routes each task to a model tier (Architecture §7). The specific providers that process your content are drawn from these tiers and change as the routing layer improves; on Pro and Studio you may bring your own model API keys, in which case requests run on your own provider account. These providers may process your content outside the UK/EEA (see our Privacy policy on international transfers); we give the same notice as above before a change adds a new provider. Your keys are envelope-encrypted per business and never logged in plaintext.
