Fireworks AI
Model serving platform and API for fast, low latency inference, fine tuning, and pay as you go access to leading open and proprietary models.
Overview
Fireworks AI provides serverless and dedicated endpoints for text, vision, and speech models with a focus on performance and cost control. Developers call a single API to access a roster of open and licensed models, choose throughput tiers, and enable streaming for interactive apps. Fine tuning and LoRA adapters are supported, and eval tools help compare quality and latency across models and parameter sizes.
Pricing is pay as you go by tokens with transparent per family rates, plus options for reserved capacity; SDKs and Terraform modules simplify integration. Teams use Fireworks to power chat assistants, RAG pipelines, and image workflows without managing GPU fleets, while dashboards track spend, p95 latency, and usage by project to keep launches predictable.

Capabilities
Low latency endpoints
Stream responses and choose capacity tiers to meet strict p95 targets for production assistants and apps.
Fine tune and LoRA
Customize models for your data and tone then deploy adapters without retraining from scratch.
Evals and metrics
Benchmark quality latency and cost across models to pick the best fit for each workload.
Cost and quotas
Use dashboards and limits to manage budget by project and prevent surprise bills.
Frequently Asked Questions
