Providers & subprocessors
This page is generated from mumo's live routing configuration each time it is rebuilt. It lists every inference provider that receives your content and the models you can select from each, the platform features that send content to a provider you did not pick, and the other service providers that process data for us.
We route only to (a) model developers serving their own models under API terms that prohibit training on submitted content, or (b) inference providers running open-weight models on their own infrastructure. We do not route through gateways, routers, or intermediaries, and we never send requests to the developer of an open-weight model.
For providers serving their own models, the no-training commitment is a term of the provider's standard API agreement, which we accepted when we opened our account — binding on both of us, but their standard terms, not a negotiated contract; marked "API terms" below and linked to the source. For inference providers running open-weight models, we rely on the provider's published data-handling statements — marked "Stated policy" below and linked to the source.
1. Inference providers
Every provider that receives the content of a conversation you start, with the models you can currently select from it. A model we no longer offer can still run in a session that started on it; it stays with the same provider and is counted here, not named.

2. Platform features that send your content
These features run models you did not pick. Each sends the content it needs to the host shown; where a fallback is configured the row reads primary → fallback, and the fallback receives the same content when the primary is unavailable. Every host named here has a row in section 1.
| Feature | Hosts |
|---|---|
| Web search: deciding whether to search | OpenAI → Google |
| Web search: query optimisation | OpenAI → Fireworks |
| Web search: source verification | Google → OpenAI |
| Round takeaway | OpenAI → Fireworks |
| Session takeaway (when you share a session) | Fireworks |
| Session title | OpenAI |
3. Subprocessors
Service providers that process data for the functions needed to operate mumo. Each processes data only on our instructions and only for the function it provides.
| Provider | Function | Receives |
|---|---|---|
| Vercel | Hosting and edge delivery | conversation content in transit; account and billing details |
| Supabase | Database and authentication | conversation content at rest; account and billing details |
| PostHog | Product analytics | interaction events — all text and inputs masked |
| Brave Search | Web search | search queries derived from your prompt |
