## Lecture Slides (Preview)

> [!NOTE]
> This release adds new capabilities for Lecture Slides, which remain
under active development and are not yet officially supported in Groups.
APIs, features, and UI/UX may change before final release.
>
> Lecture Slides mode is currently visible only to institutional admins
when creating an assistant.

### Updates & Improvements
* Lecture Video and Lecture Slides now use a shared lecture prompt
template with separate context sections for each lesson type.
* New Lecture Slide assistants now start with a slide-specific chat
prompt that grounds learner answers in slide narrations, the source PDF
deck, current slide state, and knowledge-check history.
* The Edit Assistant page now compares and resets Lecture Slide chat
instructions against the Lecture Slides default prompt instead of the
Lecture Video default prompt.
