Fireworks AI

Model serving

A hosted inference platform focused on fast, low-cost serving of open models.

Fireworks AI serves open-weight models through a fast, OpenAI-compatible API, with an emphasis on low latency and competitive pricing, plus fine-tuning and dedicated deployments.

It competes directly with the other hosted open-model clouds, leading on speed and cost.

Where it's ideally used

A fit when you want fast, cost-efficient hosted inference for open models without running GPUs.

Where it doesn't fit

A hosted API — not the choice when inference has to stay within your own perimeter.
