★★★★★
significance 2/5
Simon Willison has updated his Claude Token Counter tool to allow users to compare token counts across different models. This update is particularly relevant for Claude Opus 4.7, which features a new tokenizer that changes how text is processed compared to previous versions.
Why it matters
Granular visibility into model-specific tokenization shifts is essential for optimizing cost and context window management in production workflows.
