DeepInfra closes $107M Series B

This is a clean signal that inference infrastructure is still attracting real capital, not just hype. DeepInfra is betting on the part of the stack where usage compounds: serving, latency, and token economics. The raise fits the broader shift from training spend to production inference spend, NVIDIA participation is a useful credibility marker, and the real test is whether it can stay competitive on price and throughput as hyperscalers and model providers optimize their own stacks.
