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

TrueFoundry

Bundles an LLM gateway, model deployment, fine-tuning, and observability into one platform instead of stitching point tools together.

  • Runs in your own cloud, on-prem, or air-gapped
  • AI gateway plus model hosting in one platform
  • Enterprise governance: RBAC, audit logging
  • Framework-agnostic agent deployment
  • Enterprise-oriented; no public free tier
  • Heavier setup than a hosted-only API
  • Broad scope overlaps several point tools

When to pick which

Both cover Model inference / serving, Fine-tuning / training, and App / agent deployment.

Pick Modal if you need Sandboxed code execution and GPU compute.

  • Sandboxed code execution (secondary capability)
  • GPU compute (primary capability)

Pick TrueFoundry if you need MCP gateway / registry, LLM gateway / routing, and LLM observability.

  • MCP gateway / registry (primary capability)
  • LLM gateway / routing (primary capability)
  • LLM observability (secondary capability)
