Fireworks AI is a cloud platform for running and fine-tuning AI models, either pay-per-token or on dedicated GPUs.
In plain words
It offers two main ways to run a model. Serverless means you call popular models and pay for the tokens you use. Deployments give you your own GPUs that scale up and down. It also offers fine-tuning, and its API can be used with OpenAI-style or Anthropic-style client code.
A quick example
Imagine a startup testing an open model on the serverless option while traffic is small. When usage grows steady, it moves the same model to a dedicated deployment that scales automatically.
Where you'll meet it
- Serving models in production apps.
- Fine-tuning models for a specific task.
