Replicate vs Modal

Replicate and Modal are both AI Infrastructure & Deployment tools (Model APIs). Below: what each costs, what it does well, its biggest catches, and who should pick which, all from public sources rather than our own testing.

PricingFree tier: no flat plan; pay-as-you-go. Per-second hardware rates or per-input/output pricing per model. (checked Oct 10, 2026)Starter: free with $30/mo credits. Pay per second (e.g. A100 80GB $2.50/hr, H100 $3.95/hr). (checked Oct 11, 2026)
Pros
  • Run thousands of open models with one API call
  • Public models bill only active processing time. Setup and idle are free
  • Deploy your own models with Cog, with autoscaling
  • Python-first serverless GPUs that scale to zero, billed per second
  • Free Starter plan includes $30 of compute a month
  • Workspace budgets cap spend
Catches
  • Shared queues mean cold boots, which can take minutes for rarely used models (per Replicate's docs)
  • Private models and deployments bill setup and idle time too
  • Per-second billing means slow or stuck runs can blow up a bill (per practitioner reports)
  • Per-hour GPU rates (H100 $3.95/hr) are above bare-metal rentals
  • Cold starts matter for latency-sensitive apps
  • Egress beyond 1 TiB is billed

Which should you pick?

Pick Replicate if…

you fit this: developers prototyping with many models, or running batch jobs.

But not if: you need consistently low latency without paying to keep instances warm.

Watch out for: Shared queues mean cold boots, which can take minutes for rarely used models (per Replicate's docs)

Pick Modal if…

you fit this: python teams running bursty ML jobs.

But not if: you run GPUs 24/7. Reserved rentals are cheaper.

Pros, catches and prices are compiled from public sources (official pricing and docs pages, published reviews, user reports), not hands-on testing. Prices change often, so check the vendor page before you buy.
