Unknown model: {}

Error message

Unknown model: {}

What it means

get_model_by_name returned None when download_model_detailed tried to resolve the model definition, so the download aborts before any network activity. Registry names are exact-match ids ('qwen3.5:2b', 'qwen3.5:4b', 'gemma3:4b', 'gemma3:1b'); display names are not accepted.

Solutions

1. Pass an exact registry id including the size suffix, e.g. 'qwen3.5:4b'
2. Build the download UI from get_available_models() so ids are always in sync
3. Validate persisted model ids at startup and reset to the default model when unknown
4. Trim and validate the id before invoking the download command

let id = requested.trim();
if crate::summary::summary_engine::models::get_model_by_name(id).is_none() {
    return Err(anyhow!("Unknown model '{}' — pick from get_available_models()", id));
}
manager.download_model_detailed(id, cb).await

fn is_registry_model(id: &str) -> bool {
    models::get_model_by_name(id.trim()).is_some()
}

When it happens

Trigger: Passing a display name like 'Qwen 3.5 2B (Balanced)' instead of the id; passing a bare name without the ':size' tag; a persisted model id from an older registry version; passing another engine's model id (e.g. a parakeet model) to the summary model manager.

Common situations: Settings migration keeps an old model key after the registry changes; dropdown bound to display_name instead of name; hand-written model strings in tests.
