Fireworks 是一家位于圣马特奥的用于构建和服务定制人工智能模型的平台,已以 175 亿美元的估值筹集了15.05 亿美元的 D 轮,成为今年人工智能基础设施领域最大的私人融资轮之一。根据 Pulse 2.0 报道的详细信息以及 Quartz、雅虎财经和 HPCwire 的报道证实,本轮融资由 Atreides Management、Index Ventures 和 TCV 领投,现有投资者 NVIDIA、Lightspeed Venture Partners 和 Evantic 参与。

随着投资者将创纪录的资金投入到生成型人工智能热潮的镐子和铲子层,本次融资落地,本出版物的突发人工智能新闻部门追踪了一系列超大规模的基础设施交易。该公司认为,Fireworks 的与众不同之处不是原始计算能力,而是押注企业人工智能的未来属于根据每个公司自己的数据调整的专门模型,而不是从少数前沿实验室租用的模型。

单轮融资从 40 亿美元增至 175 亿美元

此次估值标志着大幅上涨。 Fireworks 此前以 40 亿美元的估值筹集了 2.5 亿美元的 C 轮融资,这意味着其价值在一个融资周期内大约翻了两番。这一飞跃的基础是爆炸性的商业势头:该公司表示,其年化收入运行率现已超过 10 亿美元**,同比增长五倍。

该平台的使用量也随之扩大。根据该公司的公告,同期通过 Fireworks 处理的每日代币数量已从大约 15 万亿个增长到超过40 万亿个代币。这种吞吐量反映了深度生产部署而不是实验,投资者在区分可持续人工智能业务和投机性业务时越来越要求这种区别。

押注“专业情报”

Fireworks 由 PyTorch 背后的团队创立,PyTorch 是支撑现代机器学习的开源深度学习框架。它的平台允许企业采用开源人工智能模型,并根据专有数据、工作流程和用例对其进行定制,然后大规模地在生产中为这些专用模型提供服务。

核心论文是对前沿实验室最有能力的通用模型将占据主导地位的普遍假设的直接挑战。 Fireworks 认为,封闭模型无论多么强大,都无法完全反映任何特定公司特有的领域知识、客户背景和运营工作流程,而定制的开放模型可以在企业关心的特定任务上匹配或超越它们,同时运行速度更快、成本更低。

该公司以采用作为证据:目前通过 Fireworks 提供的代币的 95% 来自定制的模型,而不是现成的使用模型。指定客户包括 Uber、Shopify、Doximity 和 Revolut。该平台提供 200 多个涵盖文本、图像和多模式格式的模型,并支持通常在发布后数小时内发布的主要新开源版本。

谁支持本轮融资

D 轮融资聚集了一个由成长型和跨界投资者组成的广泛财团。此轮融资由 Atreides Management、Index Ventures 和 TCV 共同领投。返回支持者 NVIDIA、Lightspeed Venture Partners 和 Evantic 也参与其中,此外还有来自 20VC、Bessemer Venture Partners、Insight Partners、Lone Pine Capital、Menlo Ventures 和 Ontario Teachers' Pension Plan 的新的和额外的支票。 Moomoo 和其他媒体强调了 NVIDIA 的持续支持,这是这家芯片制造商与推理计算增长最快的消费者之一之间结盟的信号。

Atreides Management 首席投资官兼执行合伙人 Gavin Baker 将此次押注视为对多模式未来的对冲。 Baker 在 Pulse 2.0 引用的一份声明中表示:“我们相信前沿模型和开放模型将越来越多地一起使用。” “凭借企业使用和信任的差异化平台来培训、定制和服务生产中的开放模型,Fireworks 处于非常有利的位置,可以释放专业智能的价值。”

Fireworks itself framed the choice in starker terms, describing two diverging paths for the industry. In one, intelligence belongs to a few large labs and everyone else simply rents it; in the other, every company builds specialized intelligence of its own, shaped by the domain only it understands. "We are building towards the second," the company said.

A Crowded, Well-Funded Field

The round intensifies an already heated race among independent AI infrastructure providers. Rivals including Together AI, which recently raised $800 million at an $8.3 billion valuation, are chasing the same enterprise demand for faster, cheaper, and more controllable model serving. What is unusual about Fireworks' position is the combination of a nine-figure revenue run rate, NVIDIA's strategic backing, and a product wedge specifically open-model customization that sits adjacent to, rather than directly under, the frontier labs.

Proceeds from the Series D will fund expansion of engineering headcount, additional global compute capacity, and deeper partnerships with cloud providers including Microsoft and NVIDIA. The company plans to keep broadening its model catalog and tightening the gap between when a new open-source model is released and when enterprises can run a customized version of it in production.

For now, the financing reinforces a broader pattern shaping 2026's AI market: the biggest capital is flowing not to the companies that build the smartest single model, but to the infrastructure that lets every other company put those models to work on its own terms. Whether specialized intelligence proves durable as a category or compresses into features offered by the cloud giants will be one of the defining questions of the next funding cycle.
