The UK’s £500 m Sovereign AI fund has made its first equity investment in Callosum, a heterogeneous AI orchestration platform, and allocated up to 1 million GPU hours to seven startups. Callosum’s software lets models and chips run together, aiming to break the Nvidia‑centric compute monopoly and boost UK‑based AI sovereignty. This backing not only accelerates mixed‑chip infrastructure but also secures talent and capital at home, positioning Britain as a global AI hardware hub.
