OpenRouter, explained.

OpenRouter gives Ferra one API for models from many providers. You get a live catalog and a separate model choice for every agent.

One catalog, many providers

Ferra reads OpenRouter’s live model list rather than shipping a fixed list inside the app. You can browse providers such as OpenAI, Google, Anthropic, Meta and others, search by name or paste a model ID.

A model per agent

A study agent can use a model suited to explanations while a writing agent uses another. The choice belongs to the agent, not to your entire account.

Images require the right capability

Not every text model accepts images. If you attach a selected photo, choose an image-capable model. Ferra’s real image flow was tested with a multimodal model, but capability still depends on your selection.

Cost depends on the model

OpenRouter and its providers set model pricing. Ferra Usage shows request counts, tokens and model-reported cost when supplied. “Free” models and Ferra’s daily free-start allowance are separate ideas.

Free start versus BYOK

Free start uses the developer’s OpenRouter account with a server-enforced daily limit. BYOK uses your account and your key. Your content is sent to OpenRouter and the selected model provider to produce the answer; their own policies apply.

Model names, availability and prices change. Always check the live catalog and your Usage screen rather than relying on an old screenshot.
