Chat with files or research
Some current card descriptions mention document, retrieval, or research workflows. Compare each card’s notes about model and backend setup.
- 02
Run a model locally
Some current card descriptions mention local or self-hosted workflows. Your device and chosen model determine what you can run.
- 03
Connect a hosted provider or endpoint
Some current card descriptions mention a provider, API, endpoint, or backend connection. A free client does not include free model access; provider plans, quotas, and charges are separate.
