# Fireworks AI

> Fast open-weight inference with strong structured-output support

- Competes with Together on the same ground: serverless open-weight inference, dedicated deployments, fine-tuning
- Differentiates on latency engineering and constrained decoding
- Grammar and JSON-schema enforcement more reliable than most hosts
- A reasonable default when output must parse every time
