# AI Token Router vs Fireworks AI

Latency-tuned serverless inference for open-weight models.

**Availability:** 7 of the 24 catalogued models are callable today. The rest are listed at their intended rate but no configured upstream serves them, so a request naming one returns `no available channel`. Every table below marks which is which.

## Side by side

| Dimension | AI Token Router | Fireworks AI | Edge |
| --- | --- | --- | --- |
| Model catalog size | 24 in the catalogue, 7 servable today (the rest marked unavailable) | Materially larger open-model catalogue; they publish no confirmed count on their own site | Fireworks AI |
| Latency on large open models | One serving tier, no latency choice | Built around speed, with Standard / Priority / Fast tiers so the buyer picks their own latency-cost point | Fireworks AI |
| Fine-tuning and training | Not offered — inference only | Serverless training API on open weights, priced per token | Fireworks AI |
| Enterprise distribution | Direct only | Also distributed through Microsoft Foundry / Azure | Fireworks AI |
| Platform fee | None. No minimum spend, no subscription | None published; $1 in starter credits for new accounts | Tie |
| Pricing transparency | Our rate and the model's official rate printed side by side on every row — 36–43% below official | The commercial pricing page carries no serverless rates; you have to click through to the docs, then read across three tiers | AI Token Router |
| Video generation | Yes — /v1/video/generations, billed at a fixed 5-second duration during rollout | None. Their serverless pricing covers text and vision only | AI Token Router |
| Billing model | Prepaid credits; the balance is a hard ceiling and exhaustion returns 429 insufficient_credits | Postpaid — usage accrues and is billed after the fact | AI Token Router |
| API surface | OpenAI-compatible across chat/completions, responses, completions, embeddings, images, speech and video | OpenAI-shaped text endpoints; no image, audio or video endpoints in the serverless catalogue | AI Token Router |

## Choose Fireworks AI when

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.

## Choose AI Token Router when

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.
