We’ve improved the multi-model experience:

• Support stopping and regenerating messages in multi-model responses

• Support pasting files and large text as file attachments when replying in multi-model threads.

• Show statistics such as token usage and estimated cost for each model.

• Fork a chat directly from a multi-model response message.

• When finalizing a multi-model response, you can now click Edit finalize instruction to customize the prompt used for that specific finalize request before picking the model to generate it.

Note: The default finalize instruction can now be customized in Settings → Advanced Settings → Internal Prompts under a new "Finalize multi-model responses" section (with a "Reset to default" option), synced across your devices via cloud sync.
