The short version

  • Only PostgreSQL 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; PostgreSQL requires manual scaling across multiple machines for very large deployments
  • They diverge on capability: Anthropic API covers Multiple models, PostgreSQL covers ACID Compliance.

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

PostgreSQL

  • Requires manual scaling across multiple machines for very large deployments
  • Performance tuning requires deep knowledge of database internals
  • No built-in graphical admin interface; command-line tools are primary method
