London-based startup Callosum Technologies, founded by two Cambridge-trained neuroscientists, has raised over 110 million dollars in total funding, including a 100 million dollar seed round led by Atomico with participation from Plural, DCVC and the UK Sovereign AI Fund. Its orchestration software breaks down AI tasks into subtasks and automatically assigns them to the optimal combination of chips and models among Nvidia GPUs, AMD processors and AWS Trainium and Inferentia chips. The company claims improvements of up to 2x in accuracy, 7x in speed and 4x in cost reduction compared to traditional homogeneous GPU configurations. Callosum specifically targets AI inference, which Deloitte estimates will account for two-thirds of AI computing needs by 2026.
