Personalized AI startup River AI raises $1.1B from consortium backed by Nvidia, AMD
River AI Inc., a startup that helps enterprises customize open-source artificial intelligence models, has raised $1.1 billion in early-stage funding.
The company stated in today’s announcement that it received the capital over two rounds, a seed and a Series A. General Catalyst and AMP PBC were the lead investors. They were joined by Nvidia Corp., AMD Ventures, Y Combinator and Temasek.
River AI is led by Chief Executive Officer Igor Babuschkin. He earlier co-founded xAI Corp. and worked at DeepMind as a researcher. Babuschkin helped develop the Alphabet Inc. unit’s AlphaCode system, the first coding AI that demonstrated competitive performance in a programming contest.
The startup’s inaugural product is a cloud service called the River API. It enables developers to tailor open-source large language models to their requirements by putting them through additional training. According to the company, the service supports LLMs with 35 billion to 1 trillion parameters.
