Descriptions:
Web Dev Cody breaks down how effort levels work in Anthropic’s Claude Opus 4.7 model, drawing on a detailed Reddit post to explain a system that controls far more than compute time. Effort acts as a behavioral signal rather than a strict token budget — at low settings, the model still reasons through hard problems, it just hits a lower ceiling sooner.
The video covers four dimensions that effort controls simultaneously: thinking depth, tool call appetite (how aggressively the model reads files and runs commands), response length, and agentic autonomy (whether the model pauses to ask for clarification or pushes through multi-step work independently). A key finding is that Opus 4.7 defaults to extra-high effort across all plans including Pro — whereas Opus 4.6 only received high effort on Team and Enterprise plans — explaining why many users perceived a quality drop when moving from 4.5 to 4.6. Low-effort Opus 4.7 is roughly equivalent to medium-effort Opus 4.6.
Practical guidance includes a model-and-effort selection matrix: Sonnet at low for file renames and simple commands, Sonnet at high for multi-file refactors and debugging, Opus at extra-high for long autonomous sessions, and Opus at Max only for architecture decisions and security reviews. Cody also flags that Opus 4.7 consumes 1.0–1.35x more tokens than 4.6, making plan-aware model switching important for Pro and Max users. One counterintuitive insight: context quality can outweigh effort level — a well-scoped prompt on low effort often beats a vague prompt on Max.
