About
Fireworks AI is the fastest inference platform for generative AI, enabling developers to build, tune, and scale AI applications using state-of-the-art open-source models. Independently benchmarked as the leader in LLM inference speed, Fireworks processes over 13 trillion tokens and powers production AI for companies like Sourcegraph, Notion, and Cursor. The platform delivers industry-leading throughput and latency through a globally distributed virtual cloud infrastructure, making it possible to run everything from code assistance and conversational AI to enterprise RAG and multimodal workflows at blazing fast speeds. Founded in 2022 by veterans from Meta PyTorch and Google Vertex AI, Fireworks AI has raised $252 million in Series C funding at a $4 billion valuation from top-tier investors including Benchmark, Sequoia, Lightspeed, Index, and Evantic. The company recently announced a multi-year partnership with Microsoft Azure Foundry, bringing high-performance, low-latency open model inference to Azure customers worldwide. With complete model lifecycle management - from build and tune to scale - Fireworks eliminates infrastructure complexity so developers can focus on shipping AI products faster.
