The company has raised $1.525 billion in funding since its inception last year. On June 29, Palo Alto-based Inflection AI announced the completion of a $1.3 billion raise led by Microsoft, Reid Hoffman, Bill Gates, Eric Schmidt and Nvidia. The new capital will be partly allocated to building a 22,000-unit Nvidia H100 Tensor GPU cluster, which the company claims is the largest in the world. The GPUs will be used to develop large-scale artificial intelligence models.
