Fireworks hits $18B valuation as companies seek cheaper AI models

Fireworks AI, an AI inference startup, reached a $17.5 billion valuation as enterprises shift toward cheaper, open-source AI models. The company projects an $800 million annualized run rate by mid-2026, up from $305 million in 2025, driven by its pay-per-token pricing and customized models that slash costs by 5 to 10 times.

Fireworks hits $18B valuation as companies seek cheaper AI models The AI inference startup's meteoric rise reflects a broader industry shift away from expensive proprietary models toward leaner, cost-effective alternatives. Fireworks AI has reached a $17.5 billion valuation as enterprises increasingly hunt for cheaper alternatives to the massive proprietary models that have dominated the landscape. For context, the company was valued at $4 billion just months ago following a $250 million Series C round in October 2025. The platform operates on a pay-per-token pricing model, deploying open-source and third-party models like DeepSeek and Qwen with low latency. CEO Lin Qiao has been vocal about the company’s approach: smaller, customized models that can slash token costs by 5 to 10 times for specialized applications. The revenue numbers back up the thesis. Fireworks AI is projecting an annualized run rate of roughly $800 million by mid-2026, up from an estimated $305 million at the end of 2025. From scrappy startup to $17.5B behemoth Fireworks AI’s ascent has been rapid even by Silicon Valley standards. The company raised a $52 million Series B at a valuation of $552 million in 2024. By late 2025, total funding had surpassed $327 million, with backers including Sequoia Capital and NVIDIA. Disclosure: This article was edited by Editorial Team.
