MODELS
Rarvis runs on the best models.
We don't train foundation models. We pick the best ones, route them well, and pay most of your bill.

Every request is metered at the vendor's official list price. You can audit every line. Compute, execution environments, and storage are included in your plan. You only pay for intelligence.
Why would you do that?
Because we're growing, and this is how we'd rather spend the money.
The models are real. Every request goes to the official API, metered at the official price. You can audit every line.
Try it with your hardest problem.
Or pick it yourself.
Rarvis 1.0 Lithium is the default. Each plan unlocks stronger models, switchable per task. When better models ship, we evaluate them and bring them here.
