The honest brief

Modal

Define GPU infra in Python decorators with 2-4s cold starts — no YAML, Dockerfiles, or managed-stack lock-in.

  • Python-decorator infra, no YAML/Dockerfiles
  • Scale-to-zero, pay only when running
  • Scales to hundreds of GPUs
  • Free monthly starter credits
  • SDK lock-in; migrating means rewriting
  • No managed vLLM/TensorRT setup
  • Costs climb under heavy usage
  • Billing hard to predict

Prime Intellect

Pairs a multi-cloud GPU spot marketplace with an open RL training stack — peers typically offer the compute or the training tooling, rarely both.

  • Multi-cloud GPU marketplace
  • Open-source RL stack (prime-rl)
  • 2,500+ RL environments hub
  • Open INTELLECT model recipes
  • Younger than major GPU clouds
  • RL stack targets advanced users
  • Spot capacity varies by provider

When to pick which

Both cover GPU compute, Model inference / serving, and Fine-tuning / training.

Pick Modal if you need Sandboxed code execution and App / agent deployment.

  • Sandboxed code execution (secondary capability)
  • App / agent deployment (secondary capability)

Pick Prime Intellect if you need LLM evaluation.

  • LLM evaluation (secondary capability)

They share capabilities, but each leads with different ones as a headline job:

Modal is built around Model inference / serving.

  • Model inference / serving (primary capability)

Prime Intellect is built around Fine-tuning / training.

  • Fine-tuning / training (primary capability)
