Gateways
Fontana provides built-in support for a wide range of LLM gateways, from unified routers such as OpenRouter and LLM API to direct vendor APIs and cloud-hosted foundation models on AWS Bedrock. All calls route through one gateway abstraction with Bring Your Own Key (BYOK): you supply the API keys your organisation holds, and administrators approve which gateways and models are reachable in production. Embeddings run on a single active profile you select in Admin → Models → Embeddings: the in-cluster TEI service by default (air-gapped, no key required), or one of the external gateways using your BYOK key.
For retention and no-training posture on each gateway, see Zero Data Retention (ZDR).
