What you can use it for

Route requests between local models and cloud providers.

  • Run a unified LLM API gateway on your own infrastructure instead of paying for a managed gateway workflow. LLM Gateway also offers free BYOK; this does not make already-free BYOK a paid feature. Provider tokens and hosting are separate costs. Firsthand evidence covers Bifrost serving access to local llama.cpp models.
Workflow coverage and comparison notes

For the gateway and routing slice of OpenRouter: run a unified API in front of local models or cloud providers using your own credentials. It does not include OpenRouter's hosted model catalogue or its free-model quota. Cloud inference, hosting and hardware are separate costs. Firsthand evidence covers serving local llama.cpp models.

Before you switch

Apache-2.0 software; run and maintain your own gateway. Unlike OpenRouter, it has no hosted model catalogue or free-model quota. Cloud models cost money; local models need suitable hardware and their own licences. Enterprise services are separate.
