Claude Code Fast Mode Defaults to Opus 4.7

Claude Code快速模式默认切换至Opus 4.7

Claude Code fast mode now defaults to Opus 4.7, and the post discloses the /fast invocation method but does not disclose pricing, context window, rate limits, or rollout conditions.

Why it matters: HKR-H/K/R pass because a Claude Code default changes to Opus 4.7 with a concrete /fast path. Sparse details on price, context window, and limits keep it in the 72–77 band.
