Fireworks AI
by Fireworks AI
#9 in Model APIs & token credits
I'd pick it to run open models in production. It speaks the OpenAI and Anthropic APIs, so switching is a URL change, and batch jobs cost half.
What’s good
- $1 in free credits to start
- OpenAI and Anthropic compatible API
- Fine-tune and serve your own models
Heads-up
- US-region model variants cost 50% more
