OpenRouter

Pros

  • + Migrated an existing assistant project in under an hour — base URL and model string were the only real changes
  • + No-markup token pricing is stated and held on the model pairs I spot-checked; the fee is a single published number
  • + BYOK: first $25,000/month of list-price inference fee-free on Standard and Business plans
  • + Public pricing API (no key) and per-model llms.txt pages make cost modelling unusually easy
  • + Model fallback turned an unreachable preferred provider into a completed request in my failure test

Cons

  • - 5.5% credit fee (card, $0.80 minimum) is a permanent tax versus paying providers directly
  • - Same-model output differed subtly between fallback providers — validators must be output-agnostic
  • - Free plan's 50 requests/day ceiling kills prototypes; caching and routing are paywalled behind Standard
  • - No SLAs outside Enterprise; your uptime is the upstream provider's uptime
  • - 500+ model count includes many near-duplicates and deprecated versions — curation is on you

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
