By working with Callosum, a frontier AI and compute software company headquartered in London, Cerebras continues to expand its European presence, on the heels of last month’s announcement that it is delivering 200 MW of European AI compute data center capacity.

Agentic inference workloads are becoming increasingly heterogeneous, with multi-agent systems operating over long-horizons in open-ended, dynamic environments. At each stage, distinct agentic reasoning and action requirements demand different computational requirements, driving the need for heterogeneous infrastructure.

The Cerebras and Callosum partnership addresses this challenge by integrating Cerebras’ silicon into the Callosum software platform. Callosum’s software decomposes and orchestrates heterogeneous agentic workloads, extracting maximum new levels of performance from new models and next-generation silicon. Cerebras' Wafer-Scale Engine delivers the ultra-low-latency inference that makes new categories of agentic AI possible. This collaboration gives customers direct and optimized access to frontier performance, unlocking new territories for Cerebras’ silicon to be utilized where it matters most.

"Agentic AI demands infrastructure that can keep up with the speed of reasoning, not just the size of the model," said Andy Hock, Chief Strategy Officer, Cerebras. "By integrating Cerebras into Callosum's platform, we're making ultra-low-latency inference available exactly where it creates the greatest impact, enabling customers to build AI systems that simply weren't practical before. This strategic partnership amplifies Cerebras' reach across Europe, equipping a massive community of innovators to achieve the impossible."

Compute infrastructure remains the key resource for scaling AI. This partnership brings frontier silicon to market through the integration layer built for the next era of AI scaling, reflecting a shared conviction on the next paradigms of scaling compute.

"The next-generation of AI will be defined by how intelligently compute is orchestrated, not simply how much compute is available," said Danyal Akarca, CEO, Callosum. "Cerebras brings unmatched inference performance. Together we've made it easy for customers to harness that capability through the Callosum platform. This partnership gives organizations a faster path to deploying sophisticated agentic AI systems while expanding access to the world's leading AI infrastructure."

Cerebras capacity will be available through Callosum APIs.
