The short version

  • Only Azure Monitor has a free tier, so it costs nothing to try first.
  • Each has a real cost: Anthropic API pricing varies significantly by model tier; Azure Monitor billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
  • They diverge on capability: Anthropic API covers Multiple models, Azure Monitor covers Log collection.

Anthropic API

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

Azure Monitor

  • Billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
  • Only the first 5 GB a month of Analytics logs is free per billing account
  • Retention beyond the base period is charged per GB per month, up to 2 years interactive and 12 years long term
  • Log queries and search jobs are billed per GB scanned, so investigating an incident costs money
  • Alert rules are billed per time series for metrics and by execution frequency for logs
  • The pricing page shows placeholders rather than rates until a region and currency are chosen
