Warm and crisp on the edges. A bagel with a bit of bite.
Summary
The article announces an upgrade to the Claude Token Counter tool, adding the ability to compare token counts across different Claude AI models. The author notes that Claude Opus 4.7 appears to be the first model with a changed tokenizer, making comparisons between 4.7 and 4.6 versions particularly valuable. The tool supports all current notable Claude models including Opus 4.7, Opus 4.6, Sonnet 4.6, and Haiku 4.5. The article appears to be a technical blog post about a developer tool for working with Anthropic's Claude AI models.
Key quotes
· 3 pulledClaude Token Counter, now with model comparisons. I upgraded my Claude Token Counter tool to add the ability to run the same count against different models in order to compare them.
As far as I can tell Claude Opus 4.7 is the first model to change the tokenizer, so it's only worth running comparisons between 4.7 and 4.6.
The Claude token counting API accepts any Claude model ID though so I've included options for all four of the notable current models (Opus 4.7 and 4.6, Sonnet 4.6, and Haiku 4.5).
