The short version

  • Only Galileo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API aWS Marketplace lists Claude Opus 4.8 (Amazon Bedrock Edition), published by seller Anthropic, at $5.00 per million input tokens and $25.00 per million output tokens for standard usage, or $2.50 and $12.50 per million tokens respectively for batch processing; Galileo the free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
  • They diverge on capability: Anthropic API covers Multiple models, Galileo covers Pre-built evaluations.

Where each one falls short

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

Anthropic API

  • AWS Marketplace lists Claude Opus 4.8 (Amazon Bedrock Edition), published by seller Anthropic, at $5.00 per million input tokens and $25.00 per million output tokens for standard usage, or $2.50 and $12.50 per million tokens respectively for batch processing
  • AWS Marketplace's Anthropic listing shows cache write tokens billed separately at $6.25 per million tokens for the standard 5-minute cache, rising to $10.00 per million tokens for a 1-hour cache TTL

Galileo

  • The free plan is limited to 5,000 traces per month, which is quickly outgrown by production workloads.
  • Real-time guardrails and unlimited trace capacity are reserved for the custom-priced Enterprise tier.
  • Pro plan pricing scales with trace volume, so costs can grow unpredictably as usage increases.
  • On-premises deployment requires an Enterprise contract rather than being available self-serve.
