Opus 4.7 xhigh Effort Level Added to Claude Code

WHAT CHANGED

Claude Code adds xhigh effort level for Opus 4.7 — sits between high and max. Available via /effort, --effort flag, and the model picker. Other models fall back to high.

WHY IT MATTERS

xhigh gives you more reasoning horsepower than high without the token cost of max. For hard coding tasks that need planning but not full max spend, xhigh is the new sweet spot.

HOW TO USE IT

Run /effort in Claude Code to open an interactive slider (new — arrow-key navigation, Enter to confirm). Or pass --effort xhigh at launch.

CLAUDE / BASH

# Launch with xhigh effort
claude --effort xhigh

# Or change mid-session
/effort xhigh

# Interactive slider (new)
/effort

The /effort command now opens an interactive slider when called without arguments. For Opus 4.7 specifically, the xhigh tier unlocks deeper reasoning on multi-file refactors and architecture work. Auto mode is now the default for Max subscribers using Opus 4.7 — no —enable-auto-mode flag needed.
