What is Fireworks AI?
Fireworks AI describes itself as a specialized intelligence platform, trusted by more than 10,000 companies according to its homepage. It offers one platform to run, ensemble and train open models.
Inference is the core product. Pricing is organized in three tiers. Pay per token starts from $0.05 per million input tokens: you call any serverless model in seconds with no commitment, and usage draws down prepaid credits. Serverless supports Standard, Priority, Fast, Batch and Spot modes, and cached input is billed at half price or less with no write fee. Reserved throughput guarantees capacity on serverless and on-demand models, backed by an SLA. A third option is Fireworks-managed inference on GPUs in your own cloud account or data center, aimed at data residency and existing GPU capacity.
Beyond inference, the site describes routing across models to balance accuracy and cost, and training on your own data. It also links to a Discord community and a status page.
