Master the @ Mention panel in Colab Canvas. Learn to strictly lock models like Nano Banana or Veo 3 and attach specific project resources. Understand the priority logic vs. Model Select.
Colab Mention

The @ Mention panel is used to explicitly select resources in the current conversation, so the agent strictly uses them as context when generating content.

​
Core usage

  • Type @ in the input box to open a searchable list.
  • Choose an image, model, or project from the list, and it will be attached to the current generation request.

​
Selection logic

  • When you @ mention a model, this is a selection logic: the system will execute with the exact model you call, not just treat it as a soft preference.
  • Key difference: the Model Select panel defines preferences, while @-mentioning a model is a strong, high-priority instruction that overrides preferences.
*Each conversation input can include a maximum of 10 elements combined (files, images, mentions, etc.).
