What Are fal.ai and OpenRouter?

Both are gateways. Neither trains models of its own: they sit in front of many providers and give you one account, one balance and one key for all of them.

OpenRouter

Covers language and reasoning: the Assistant and Flow Studio AI.

Behind a single OpenRouter account you can reach models from Anthropic, OpenAI, Google and others, plus a long tail of open models at much lower prices. In RhinoArtisan you pick which one each feature uses from a curated list, so you are not scrolling through hundreds of options that make no sense for jewelry work.

fal.ai

Covers images, video and 3D: everything in Generative AI.

fal.ai specializes in running generative media models fast. It hosts the current image and video models (Nano Banana, Veo, Kling and their peers) on infrastructure built for them, which is why a generation comes back in seconds rather than minutes and why nothing needs a GPU on your side.

Why a gateway instead of one lab

Three reasons, all of them yours rather than ours.

You are not locked in. If the best model for your work changes labs next quarter, you change a dropdown. Nothing about your setup, your key or your billing has to change.

One balance instead of five. Signing up directly with each lab means separate accounts, separate cards and separate minimum spends. A gateway collapses that into one prepaid balance.

Access to cheap models as well as expensive ones. The same key that reaches a frontier model also reaches small, inexpensive ones. That is what makes choosing per feature worth doing.

Setting both up takes a few minutes and is covered in Creating and connecting your accounts.
