Agent Infrastructure
EvaluatingFireworks AI
A hosted platform for running and fine-tuning open models like DeepSeek, Qwen, Llama, and Kimi. Start pay-per-token with no servers to manage, then move to dedicated capacity when a workload gets serious.
The AIE Angle
Why Fireworks AI made the cut
Fireworks is what you use when you want open models without running any infrastructure. You pick a model like DeepSeek, Qwen, Llama, or Kimi, call it through an OpenAI-compatible API, and pay per token. When a workload grows, the same models can move to dedicated deployments with reserved capacity, so you don't have to rebuild anything. The part that sets it apart is fine-tuning. You can adapt a base model to your own data with LoRA and serve several of those tuned versions side by side, which is how a company ends up with a model that knows its terms and formats without training anything from scratch. For most people the move is simple: prototype on Fireworks, see whether an open model handles the job, and decide later whether it's worth owning the hardware. It's also available as a provider behind OpenRouter.
Independently tested. No pay-to-play.

Can I fine-tune models on Fireworks?+
Yes. Fireworks supports LoRA fine-tuning on your own data and can serve several tuned variants of a base model at once.
How does Fireworks compare to OpenRouter?+
