The short version

  • Only Comet ML 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; Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention
  • They diverge on capability: Anthropic API covers Multiple models, Comet ML covers Experiment tracking.

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

Comet ML

  • The free cloud tier caps data at 25,000 spans a month with 60 day retention
  • Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
  • Overage on Pro is $5 per additional 100,000 spans
  • The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
  • Pro MLOps is $19 per user per month and caps the team at 10 users
