Provider not found

Error message

Provider not found

What it means

The thread has a model, but its provider_id is absent from the global LanguageModelRegistry. map_language_model_to_info needs the provider for metadata and display info, so the request fails even though the model id itself is known.

Solutions

1. Enable or sign in to the provider the model belongs to, or switch the thread model to one from an active provider.
2. If it happens at startup, re-query after the registry finishes loading (observe LanguageModelRegistry for changes).
3. Prune stale model ids from settings (favorite_model_ids / default_model) that point at removed providers.

Example fix

// before
let info = connection.selected_model(cx).await?; // "Provider not found"

// after
let model = thread.read(cx).model().unwrap(); // guarded earlier
let provider_ok = LanguageModelRegistry::read_global(cx)
    .provider(&model.provider_id())
    .is_some();
if !provider_ok { /* pick another model */ }

let Some(model) = thread.read(cx).model() else { return };
let provider_available = LanguageModelRegistry::read_global(cx)
    .provider(&model.provider_id())
    .is_some();
if !provider_available {
    // choose a model whose provider is registered, or defer until registry loads
}

fn provider_registered(provider_id: &LanguageModelProviderId, cx: &App) -> bool {
    LanguageModelRegistry::read_global(cx).provider(provider_id).is_some()
}

When it happens

Trigger: The model references a provider that is disabled, signed out, not yet loaded, or removed; querying selected_model during startup before providers have registered in LanguageModelRegistry.

Common situations: Settings synced from another machine referencing an unavailable provider; signing out of hosted models; disabling a provider extension; init-time races before the registry populates.
