The models' case: The category benchmark for distributed DL — low-overhead logging from every rank of a multi-node job, robust run grouping/resumption for interrupted large jobs. The models' main caveat: Proprietary SaaS whose cost and vendor lock-in bite at high logging volume. The strongest alternative is Neptune.ai — Its Neptune Scale rearchitecture was explicitly built for foundation-model-era runs — millions of steps, thousands of concurrent distributed.
