PricingFree tier: no flat plan; pay-as-you-go. Per-second hardware rates or per-input/output pricing per model. (checked Oct 10, 2026)Serverless per token (varies by model). Dedicated: H100/H200 $8/hr, B200 $13/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
  • Fast serverless inference for open models, billed per token
  • Cached input is about 50% off and batch jobs cost half
  • Dedicated GPUs per second with no startup charge
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)
  • Prepaid, usage-based billing needs monitoring
  • Dedicated H100s at $8/hr cost more than raw GPU rentals
  • Developer-only, with no consumer app
