Fireworks AI, a platform specializing in building and scaling AI on open models, has closed a $1.5B Series D funding round. The substantial capital infusion underscores the growing demand for infrastructure that can quickly deploy production-ready AI, a service Fireworks provides via its globally distributed cloud.
The company currently powers critical workloads for major players like Uber, Doordash, Notion, and Cursor. Fireworks AI claims its optimized infrastructure delivers significant performance advantages, including 15 times faster speed, four times lower latency, and four times more concurrency compared to closed models.
