About Fireworks AI

Fireworks AI provides the fastest inference for generative AI, enabling companies to train and serve open models with high throughput and low latency. It is independently benchmarked as the leader in LLM inference speed.

Fireworks AI builds foundational infrastructure for specialized intelligence, offering a full spectrum of model training options—from guided runs to custom RL—and inference serving (serverless, on-demand, and reserved). Their platform transforms leading open-source models into specialized intelligence for enterprises. Customers include Cursor, Vercel, Notion, Genspark, Quora, Sourcegraph, and UiPath.

Revenue is generated through per-token pricing for serverless inference and dedicated deployment fees. The company is Series C, valued at $4 billion, and backed by Benchmark, Sequoia, Lightspeed, Index, and Evantic. Founded by veterans of Meta PyTorch and Google Vertex AI, Fireworks AI focuses on delivering high-performance AI infrastructure at scale.
