UK’s Callosum in talks to raise $100m

‘New chips and architectures are arriving from every direction, but no infrastructure has existed to bring them together,’ says Callosum.

The company believes that by using a variety of processor architectures it can get AI software programmes to perform better than if they ran on a single architecture.’

The company develops a systems-level orchestration software optimisation layer which distributes  AI workloads across different chip architectures. 

It assigns different parts of a workflow or different models to the hardware where they perform best (for speed, cost, accuracy, or power efficiency).

It  enables “co-evolution” of chips and algorithms, supporting multi-model/agent systems that is claimed to out-perform systems which only use one processor architecture.

It claims  significant performance improvements from exploiting the strengths of varied silicon rather than relying on uniform GPU clusters. 

The company was founded by University of Cambridge researchers Dr Danyal Akarca and Jascha Achterberg (pictured ).

It is backed by the venture fund Plural, the UK Sovereign AI Fund, and Aria, the government innovation lab.
