What probably matters to youSection of the release
Unclear Which users are shown the upgrade option in the dialog is not known.
What
The model consent dialog appears when you pick or reach a model that needs your agreement or a different plan. When you choose its upgrade option, Claude Code now runs /upgrade for you, which opens the upgrade page to switch to a higher plan tier. This happens in two places:
the model picker's consent dialog
the dialog shown in the middle of a session
Before, choosing that option only showed a message. /upgrade itself is available only to claude.ai accounts.
Why
If you hit a model your plan doesn't cover, you can get to the upgrade page in one step.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed sinceAnthropic's documentation has since written up /upgrade, on Claude Code changelog.* Fixed usage-limit warnings suggesting `/upgrade` to users already on the highest Max plan; the warnings and `/upgrade` itself now point at `/usage-credits` when it is availablechangelogsee the edit
