Model {model_name} not found. Available: {available}

Error message

Model {model_name} not found. Available: {available}

What it means

model_not_found_error builds a diagnostic after the model discovery wait timed out or was skipped: the requested provider/model pair is not among the registry's available_models, and the message enumerates what IS available (or '(none)'). It fires when MODEL_DISCOVERY_TIMEOUT elapsed without the model appearing, meaning the model id is misspelled, not offered by the provider, or discovery failed entirely.

Solutions

1. Check the 'Available:' list in the error and correct the --model provider/model spelling
2. If the list is '(none)', fix provider configuration/authentication first — discovery produced no models
3. Increase the discovery wait if the provider catalog is slow to load
