When you should choose Fireworks AI
If tokens-per-second is the number your product lives or dies on — voice agents, interactive coding, anything where the user is watching the response render — Fireworks is built for exactly that, and they let you buy more of it explicitly through Standard, Priority and Fast tiers rather than making you hope. They also carry more Kimi SKUs than anyone else we looked at, including a US-hosted variant that matters if data residency is on your checklist, and they will fine-tune on open weights and serve the result. If you are already on Azure, they are available there and we are not. None of that is something we can match today.
When you should choose us
If you want to know what a request costs before you send it, without opening a docs page and reconciling three tiers, and you want video generation on the same key and the same balance — that is the whole reason this exists. Prepaid credits also mean the bill cannot surprise you: when the balance hits zero the API stops, it does not keep spending.
