The short version

  • Only Galileo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API pricing varies significantly by model tier; 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.
  • 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

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.

Self-serve access uses usage-based tiers with automatic rate limit increases as volume grows. Enterprise customers receive custom rate limits, monthly invoice billing, and hands-on support at negotiated pricing.

Source
Galileo: How is usage metered?

Galileo's pricing scales based on the number of traces processed each month, with Free capped at 5,000, Pro at 50,000, and Enterprise offering unlimited trace capacity.

Source
Anthropic API: How much extra does US-only inference cost on the Claude API?

US-only inference costs 1.1x pricing for input and output tokens across all model tiers compared to standard multi-region pricing.
