A recent analysis of Anthropic's Claude Opus 4.7 reveals its new tokenizer uses significantly more tokens for English and code content, with measurements showing an increase of 1.20x to 1.47x compared to Claude 4.6. This means users will consume their context windows and rate limits faster at the same price. Anthropic suggests this change enhances literal instruction following, potentially reducing errors in tasks requiring precise adherence to constraints. AI
