Claude Token Counter, now with model comparisons

The Claude Token Counter now allows comparing token counts across models (Opus 4.7/4.6, Sonnet 4.6, Haiku 4.5). Opus 4.7 changes the tokenizer, inflating token counts (up to ~1.46x vs 4.6) and pricing; it also improves image support. The post shares benchmarks for text, images, and PDFs to help estimate costs.
