The short version

  • Only ChatGPT 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; ChatGPT openAI's own pricing page, as captured by the Internet Archive in 2023, listed ChatGPT Plus at $20 per user per month, Team at $25 to $30 per user per month with a minimum of 2 users, and Enterprise available only from 150 users. The live page refuses automated reads, so these are 2023 figures and the tiers have changed since.
