Models and plans

Reference archive: this page documents the original Yab browser. Features, platforms and release dates here do not describe the current Veb prototype. Veb release plans →

Which model does what, the plans they come from, and what happens when one runs out.

Settings › AI › Models shows your plans at the top: Apple Intelligence, Apple’s own model on this Mac, free and private, for short text (macOS 26 with Apple Intelligence on), then your Claude and ChatGPT accounts. A ring beside each account shows how much of it is used; click it for the details and when it resets.

Which model does what#

  • Tasks: what you ask with ⌘J, ⌘T and the chat, and routines.
  • Commands: commands on selected text your Mac’s model can’t do. A command can have its own.
  • Form drafts: answers to a form’s questions, on Claude.

Claude’s models run on your Claude plan, GPT’s on your ChatGPT plan. Each has an effort, from Low to Max. Claude’s names always mean the newest release: Fable, Opus, Sonnet, Haiku.

In the chat, click the model under the title to switch; ↩ takes one and ← → change its effort. Models whose plan has run out are dimmed.

More than one account#

Add Account signs in another Claude or ChatGPT account, in a private tab. Tasks use the accounts top to bottom; Try First puts one on top.

When a plan runs out#

Before a task starts, Veb asks your plans how much room they have. A task starts on the first account with room, and if one runs out partway, the same conversation carries on with the next. A new chat whose plan has no room on any account starts on the other plan, if it’s connected and has room, and says so: Claude is out of room, back 10:00 PM, so ChatGPT took this chat.

A chat already under way stays on its plan. When every account of it runs out, the chat says when it’s back, and that a new chat can go on the other plan meanwhile.
