The short version

  • Only Modal has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API pricing varies significantly by model tier; Modal the Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • They diverge on capability: Anthropic API covers Multiple models, Modal covers Serverless GPUs.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Anthropic API

  • Pricing varies significantly by model tier
  • Batch processing and Fast Mode add additional surcharges
  • US-only inference costs 1.1x standard pricing

Modal

  • The Team plan carries a $250 monthly base fee and returns only $100 of that as free credits, so $150 is a flat charge before any compute
  • Compute is billed per second across separate GPU and CPU meters, so total cost depends on execution time rather than any fixed rate
  • The Starter plan's $30 monthly free credit is the only allowance below the paid base fee
  • Enterprise volume discounts are custom and unpublished
