The short version

  • Each has a real cost: Alchemy the free tier is capped at 30M compute units a month and 25 requests per second; Replicate private model deployments are billed for all the time instances are online, including setup and idle time, not only for processing
  • They diverge on capability: Alchemy covers Node APIs, Replicate covers Model hosting.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Alchemy

  • The free tier is capped at 30M compute units a month and 25 requests per second
  • Free accounts are limited to 5 apps and 5 webhooks
  • Beyond the free allowance it is $0.45 per 1M compute units for the first 300M a month
  • Request cost varies by call complexity, from around 10 compute units to over 100, so spend is hard to predict from request counts alone
  • Signed SLAs and priority support require an Enterprise contract

Replicate

  • Private model deployments are billed for all the time instances are online, including setup and idle time, not only for processing
  • Multi-GPU A100, H100, H200 and L40S capacity beyond the listed configurations is only available with a committed spend contract
  • The pricing page publishes no free tier allowance
