Fireworks, an inference cloud startup backed by Nvidia, expanded its platform for hosting open-source AI models that developers can integrate into software applications. The company announced a $1.5 billion funding round at a $17.5 billion valuation and said it had surpassed $1 billion in annualized revenue, representing fivefold growth from the previous year.
The platform provides computing infrastructure for running AI models and has also expanded into GPU capacity for model training. Fireworks competes with major cloud providers such as Amazon and Google, as well as inference-focused startups including Baseten and Together AI. Its growth comes as finance leaders increasingly encourage employees to consider lower-cost open-source alternatives to expensive proprietary models.
For developers and enterprises, Fireworks offers another route for deploying AI models without relying entirely on the largest cloud platforms or closed-model providers. Its revenue growth reflects rising demand for specialized AI infrastructure that prioritizes model flexibility, inference efficiency and lower operating costs.
