Fireworks AI

Profile Overview

Fireworks AI is a developer platform and model deployment startup founded in 2022 by Lin Qiao, former director of AI engineering at Meta, along with other key engineers behind PyTorch and Caffe2. Headquartered in Redwood City, California, Fireworks AI provides a high-performance, developer-friendly API platform designed to deploy, run, and customize open-weights generative AI models at production scale. The company's proprietary inference engine is optimized for extreme speed and cost efficiency, delivering serverless model execution (for models like Llama 3, Mixtral, and Stable Diffusion) that is multiple times faster than standard cloud setups. Fireworks AI also offers an advanced customization platform, allowing companies to fine-tune foundation models on their proprietary data using LoRA (Low-Rank Adaptation) and deploy those adapters with sub-millisecond cold start times. This allows businesses to run hundreds of custom, domain-specific models efficiently on shared GPU infrastructure. In July 2024, Fireworks AI raised $52 million in a Series B round led by Sequoia Capital, bringing its total funding to $77 million at a valuation of $552 million. Fireworks AI is widely recognized as a premier tooling partner for enterprises building production-grade agentic and RAG applications.
