Anonymous Opus 4.7 Token Comparison Leaderboard Hits 520pts — Practitioners Quantify the Token Tax

Hacker News·medium signal

A community-built anonymous leaderboard at tokens.billchambers.me comparing request-level token usage between Opus 4.6 and 4.7 hit 520 points on HN, the hottest Opus 4.7-related discussion this week. Opus 4.7's new tokenizer maps the same input to 1.0-1.35x as many tokens depending on content type, and the model generates more output tokens at higher effort levels. For builders, this means Opus 4.7's benchmark gains come with a measurable cost increase that practitioners are now quantifying in production.
