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

Vercel

Productized Next.js: git-push to a global edge network, with the AI SDK and v0 generation in one account.

  • Zero-config deploys for frontend frameworks
  • Global edge network + per-PR preview URLs
  • First-party Next.js + AI SDK + v0
  • Generous hobby tier
  • Costs can scale steeply at high traffic
  • Best fit is the Next.js ecosystem
  • Some lock-in to platform primitives

When to pick which

Both cover App / agent deployment.

Pick Modal if you need Sandboxed code execution, GPU compute, Model inference / serving, and Fine-tuning / training.

  • Sandboxed code execution (secondary capability)
  • GPU compute (primary capability)
  • Model inference / serving (primary capability)
  • Fine-tuning / training (secondary capability)

Pick Vercel if you need LLM gateway / routing, Multi-model access, and AI app builder.

  • LLM gateway / routing (secondary capability)
  • Multi-model access (secondary capability)
  • AI app builder (primary capability)

Vercel leans on App / agent deployment as a headline capability; Modal treats it as secondary.
