According to Fortune, AI startup Callosum has completed a $10.25 million funding round. Callosum is developing software that can coordinate AI workloads across various types of chips, challenging the industry's reliance on running increasingly larger models on a large number of identical Nvidia GPUs.

This funding round was led by Plural, a European early-stage venture capital fund, with participation from angel investors such as Charlie Songhurst, Stan Boland of FiveAI, and John Lazar from the Royal Academy of Engineering.
