River AI 筹集 11 亿美元用于个人 AI 技术栈
战略概览
- 01.由 xAI 联合创始人 Igor Babuschkin 创立的 River AI,在 2026 年 8 月 11 日宣布完成了一轮合计 11 亿美元的种子轮和 A 轮融资,距离该公司于 2026 年 6 月结束隐匿状态仅两个月。
- 02.本轮融资由 General Catalyst 和 AMP PBC 共同领投,Nvidia、AMD Ventures、Y Combinator 和 Temasek 参投。
- 03.River 的首款产品 River API,提供针对 350 亿至 1 万亿参数的开源权重模型(包括 Qwen3.6、Kimi K2.6 和 GLM 5.2)的 LoRA 微调和强化学习服务,按 token 计费,而非按 GPU 小时计费。
- 04.River 的长期计划是打造完整技术栈:训练基础设施、个性化与持续学习产品,以及定制 AI 硬件,使个人 AI 能在用户身边运行,而非在他人数据中心中运行。
深度分析
免费权重,付费工具:River 的‘核心免费’模式
River 的首款产品 River API 并不销售模型本身,而是销售微调能力。客户可在 350 亿至 1 万亿参数的开源权重模型(包括 Qwen3.6、Kimi K2.6 和 GLM 5.2)上应用 LoRA(一种训练小型适配器层而非重新训练整个网络的技术),并结合强化学习,按 token 计费而非按 GPU 小时计费 [5]。River 声称,无需内部基础设施团队,即可在 15 至 20 分钟内部署完整的强化学习训练流程,成本仅为闭源替代方案的 2 至 4 倍 [1]。这种定价逻辑反映了 Babuschkin 在融资时提出的更广泛论点:“当前构建 AI 的方式,并非未来 AI 的构建方式。AI 应该是开放的、可自由获取且负担得起的。” [6]General Catalyst 的 Marc Bhargava 以类似术语描述 River 所填补的空白:“River 弥合了这一差距,帮助任何公司基于自身数据构建模型,并根据其实际工作方式进行定制。” [6]
从 DeepMind 到 xAI 再到 River:不仅是产品,更是一场所有权之争
Babuschkin 的职业轨迹贯穿 Google DeepMind 的生成建模与强化学习研究、OpenAI 的大规模训练,以及作为 xAI 联合创始人的经历,他于 2025 年 8 月离开 xAI [3],数月内便创立了 River。他对这家新公司的公开表述既具哲学意味又具商业考量:他曾将最终状态描述为个人 AI 硬件,“属于你,而非租用,你对其拥有真正的控制权” [3]。General Catalyst 首席执行官 Hemant Taneja 将这一理念上升至地缘政治层面,称开源权重领域的领导地位是一项战略优先事项:“美国在 AI 领域的领导地位迫切需要在开源权重模型方面取得领先地位,同时保持在闭源前沿模型上的优势。” [6]

THE SIGNAL.
“认为当前封闭实验室的 AI 开发模式是暂时的,AI 应该是开放的、负担得起的,并由用户拥有,而非租用。”
“描述了个人 AI 硬件的长期愿景,即用户完全掌控,而非租用数据中心的算力。”
“将此次投资视为美国在开源权重 AI 模型和闭源前沿模型领域保持领导地位的战略必要之举。”
“认为 River 填补了企业缺乏高效成本方式在自有数据上训练和拥有定制模型的空白。”
“Today, we are sharing that River AI has raised $1.1 billion, led by @generalcatalyst and @amppublic with strategic investment from @nvidia and @AMD. Additional investors include @ycombinator and @Temasek. We imagine a future where your AI works entirely for you and deeply aligns...”
“We have raised $1.1B to build AI that is owned and shaped by each of us. Check out the article published by the The New York Times that explains River AI mission and where we are going next. Our first product is the River API which allows anyone to build custom agents and LLMs...”
“NEWS: Former xAI co-founder Igor Babuschkin raised $1.1 billion for his new AI company, River AI. The round was led by General Catalyst and Amp, with strategic money from chip giants Nvidia and AMD. Y Combinator and Temasek also joined. River AI goal is personal AI that you...”
