Anthropic's Opus 4.7 Costs More Despite Flat Pricing

The Decoder

In brief

  • Anthropic has released Opus 4.7, a new version of its AI model.
  • While the cost per token remains the same as before, users are noticing higher overall expenses.
    • This is because Opus 4.7 uses a more detailed tokenizer that breaks text into up to 47% more tokens than its predecessor.
    • This change affects developers and researchers using Claude Code, as their costs for processing tasks like coding assistance or language generation have risen significantly.
  • Early measurements show that even though each token is priced the same, the total cost per request is notably higher due to the increased number of tokens processed.
  • Looking ahead, users will want to monitor how this impacts the efficiency and affordability of AI tools relying on Opus 4.7.

Terms in this brief
