You control which LLM provider families and model IDs are available in your organisation. Fontana ships 300+ supported models across leading providers: frontier chat and reasoning models, open-weight endpoints, and domain-specific hosts, all routed through your approved gateways and BYOK keys (see Gateways). Usage stays aligned with your contracts, compliance posture, and budget because inference never runs through a shared Fontana-operated model account.
