The short version

  • 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; Google Vertex AI vendor lock-in to Google Cloud ecosystem makes migration to other platforms difficult
  • They diverge on capability: Anthropic API covers Multiple models, Google Vertex AI covers AutoML.

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

Google Vertex AI

  • Vendor lock-in to Google Cloud ecosystem makes migration to other platforms difficult
  • Requires familiarity with Google Cloud Platform infrastructure and concepts
  • Cost can escalate quickly with large training and inference workloads
