Replicate

Pros

  • + First model call took one API request with no infra work; workshop participants all ran a model in under 15 minutes
  • + Scales to zero — my low-volume serving cost cents per day because the meter stops when requests stop
  • + Transparent per-second hardware table from $0.000025/s (CPU small) to $0.011200/s (8x A100)
  • + Per-output pricing on popular models (FLUX at $0.025-$0.04/image) with per-run cost estimates on model pages
  • + Cog open-source packaging plus fast-booting fine-tunes covers the custom-model path

Cons

  • - Cold starts of 30-60 seconds on idle community models — user-facing features need warm-ups or loading states
  • - Private models on dedicated hardware bill for idle time; I paid for a forgotten instance
  • - Community library quality variance is huge and nothing on the pricing side helps you judge it
  • - No frontier proprietary models, agent tooling or RAG stack — component, not platform-of-record
  • - Acquired by Cloudflare (Nov 2025); multi-year pricing and roadmap certainty is a due-diligence item

Modal

Pros

  • + Slim-image containers accepted work in ~1-3s from zero in my tests; heavyweight torch+7B init ran 15-25s, consistent with the docs' seconds-to-minutes range
  • + Per-second metering reconciled against my own container-uptime arithmetic within a percent or two over several weeks
  • + Fan-out to 50 workers took one decorator and no queue plumbing; scaling up and back was invisible in the code
  • + Full public rate card: H100 $0.001097/sec down to T4 $0.000164/sec, plus $30/month free credits on the Starter plan
  • + Sandboxes (1B+ instances launched per company figures) give a built-in answer for running AI-generated code safely

Cons

  • - Python only — no first-class Go, Rust or Node story for polyglot teams
  • - Billing covers container uptime including cold starts: a 20s model load on H100 costs ~$0.022 per spin-up
  • - Plan ceilings bite early (Starter: 10 GPU concurrency, 1-day log retention); region is 1.15-1.75x and non-preemptible/Sandboxes 3x
  • - No model catalogue — checkpoint serving and inference frameworks are your own code
  • - HIPAA, SSO and audit logs are Enterprise-tier, pushing regulated workloads into a sales process
