Modal
Same categoryServerless GPU compute defined in Python, billed by the second
For developers who want to define their entire inference workload in Python and pay only for the seconds of compute they use, Modal offers the closest match. Its image declaration sits beside the code that runs on it, so no Dockerfile is required, and per-second billing with automatic scale-up suits bursty or experimental workloads where per-minute rounding would add up. The best audience is an engineering team comfortable writing Python that runs training, fine-tuning, and inference on the same platform and wants a broad GPU range from T4 through B300. The tradeoff is that Modal has no prebuilt model catalogue or per-token API, so every model must be supplied by the customer, and the Team plan costs $250 per month before any compute is consumed.
Best for: Python-native teams running bursty or experimental inference, training, and fine-tuning who want per-second billing and no Dockerfile requirement
Consider: No prebuilt model catalogue or per-token API, and the Team plan costs $250 per month before any compute is used
