> 2x month-on-month user growth at 60% lower cost. More scientific work per quota drives higher retention.

- **2x**: “2x month-on-month user growth at 60% lower cost.”
- **24 hours**: “New state-of-the-art open models in production within 24 hours”

> We feel like Fireworks is part of our internal team, especially part of our engineering team. This inference service is very critical to our product experience, so having a trustworthy partner on both the business side and the engineering side was a huge factor in the decision.
