Modal vs Prime Intellect (2026)
Modal and Prime Intellect both put GPUs behind Python code, and the split is serving against research.
Modal is a Python native serverless cloud with sub second cold starts, per second billing and isolated sandboxes for running untrusted agent code at scale, free to start and 250 dollars a month for a team. Prime Intellect is open infrastructure for training and running agents, with a GPU marketplace quoted across fifty plus providers and an end to end reinforcement learning, evaluation and deployment platform. Choose by which problem you have this quarter: shipping an agent, or teaching one.
Choose Modal if
- You are serving agent workloads and cold start latency is a user facing number.
- Running untrusted agent generated code safely at scale is the requirement.
- Python native ergonomics matter: your infrastructure should look like the code you already write.
Choose Prime Intellect if
- Reinforcement learning is the actual work, and you need environments and evaluation, not just execution.
- You want to shop GPU price across many providers rather than accept one vendor's rate.
- Documented evaluation coverage is the strongest thing on Prime Intellect's card and the reason to pick it.
