Claude Token Counter, now with model comparisons

The blog post discusses an upgrade to the Claude Token Counter tool, allowing users to compare token counts across different Claude models (4.7, 4.6, Sonnet 4.6, Haiku 4.5) and highlights the changes in tokenization and pricing due to model updates. Notably, Opus 4.7 features a new tokenizer that inflates token counts, resulting in higher costs for processing inputs.
