DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.140

Fast Mode Now Supports Opus 4.7

What

The /fast toggle and its description have been updated to include Claude Opus 4.7 alongside Opus 4.6.

Details
  • Old description: "…is only available on Opus 4.6."
  • New description: "…is available on Opus 4.6 and Opus 4.7."
  • No change in behavior; /fast enables the same faster-output mode, now on an expanded set of models.
Evidence

Updated fast-mode description string (search for "available on Opus 4.6 and Opus 4.7")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
