Source Intelligence

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.

Rate-limit prompts resolve model aliases to the model that actually answers

Rate Limits

Rate-limit prompts now resolve model aliases, so you get fewer misdirected limit warnings.

What

Prompts and warnings tied to a specific model now look through aliases: opusplan and opusplan[1m] count as Opus, haiku counts as Sonnet. You get fewer confirmations and fewer misdirected limit warnings when running on an alias.

Details
  • Replaces three separate yes/no alias checks: the main-model confirmation loop now skips confirmation for aliased models, the seven-day Opus and Sonnet limit notices no longer fire when the alias already resolves to that family, and the extra-usage upsell is suppressed for aliased models.
  • Any model that is not one of those aliases resolves to nothing and behaves as before.
Evidence

opusplan[1m]

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