Comparison
FastMetal vs OrcaRouter
OrcaRouter is built by Continuum AI in the US and distributed in Japan by FlashLabs, which launched it here in May 2026. It puts 200+ models behind one API and offers adaptive routing that grades each request and sends it to a model that suits it.
Choosing a model automatically is common ground. The entry point is not. OrcaRouter prices and holds balances in USD with a $20 minimum top-up; FastMetal is yen-native from ¥500, by card or bank transfer. The routing differs too: OrcaRouter grades by difficulty, FastMetal picks the cheapest capable model per request.
