Tip: 14 Hours of Opus 4.7 — Clear Intelligence Upgrade, But Token Consumption Up Significantly

r/ClaudeAI·medium signal

A practitioner's 14-hour deep session with Opus 4.7 (154 upvotes, 42 comments on r/ClaudeAI) confirms it's a clear intelligence upgrade over Opus 4.5, not 4.6. The catch: users spend more tokens due to the model's new behavior patterns — longer reasoning chains, more thorough responses. Combined with the tokenizer's up-to-35% token inflation, real-world cost per task is materially higher. The recommendation: use /effort to dial down reasoning depth for routine tasks and reserve xhigh for complex architecture decisions.
