Macrocosmos Targets 70B-Parameter Training on 5,000 Distributed Nodes
Steffen Cruz, co-founder and CTO of Macrocosmos, argues that frontier AI training is approaching an economic ceiling as larger models require multi-billion-dollar, centralized GPU build-outs. Macrocosmos’s alternative, built inside the BitTensor ecosystem, is IOTA: a distributed training network that uses blockchain for identity, coordination, auditability, and payment while training happens off-chain across idle or underused machines. Cruz says the system has reproduced baseline benchmark performance and now needs to prove it can train enterprise-relevant models, starting with a 5,000-node and roughly 70 billion-parameter target.
