由xAI联合创始人Igor Babuschkin创办的AI初创公司River AI在成立仅两个月后，宣布获得General Catalyst和AMP PBC领投的11亿美元融资[1]。Nvidia、AMD Ventures、Y Combinator和淡马锡等机构也参与了本轮投资[1]。
River AI致力于从零开始重新发明AI，打造可个人化训练的AI助手，而非单纯的人类工作替代品[1]。该公司推出了按100万tokens计费的API产品，支持强化学习和低秩适配微调[1]。River AI声称任何企业可在15-20分钟内完成复杂强化学习运行，成本相比闭源方案可节省2-4倍[1]。
River AI, an artificial intelligence startup founded by xAI co-founder Igor Babuschkin, has secured $1.1 billion in funding just two months after its public emergence in June [1]. The round was led by General Catalyst and AMP PBC, with participation from major investors including Nvidia, AMD Ventures, Y Combinator, and Temasek [1].
The company is positioning itself to fundamentally reimagine AI development from the ground up, moving away from models designed primarily as human job replacements toward personalized AI assistants that can be trained for individual use cases [1]. River AI's core offering includes an API priced per million tokens, supporting reinforcement learning and low-rank adaptation fine-tuning capabilities [1]. According to the company, enterprises can execute complex reinforcement learning tasks within 15 to 20 minutes using its platform, achieving cost savings of two to four times compared to closed-source alternatives [1].
