RunPod A100 80GB is $1.89/hr; Modal A100 80GB is $3.40/hr. Almost 2x. But Modal's Python-native function model — you write a decorator, they handle scaling, packaging, secrets, and GPUs — saves real engineer time. For a lean team shipping inference workloads, that DX often justifies the cost. For batch jobs or established pipelines, RunPod's pricing wins.
