Release Notes
This update includes bug fixes and improvements.
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
- Longer Lecture Slide lessons with shorter transcripts can now generate in a single pass instead of being split only because of duration.
- Lecture Slide manifest generation now estimates prompt size before splitting processing into chunks, improving reliability for large or transcript-heavy slide decks.
- Lecture Slide processing now uses tokenizer-based chunking so generation requests stay within model input limits while preserving context around chunk boundaries.
- When a Lecture Slide generation request still exceeds the model context limit, PingPong now splits the affected chunk near the transcript midpoint and retries the smaller pieces.
Resolved Issues
- Fixed: Lecture Slide manifest generation may hit model context limits for dense decks because chunks were based on duration rather than source size.
- Fixed: Lecture Slide PDF previews may fail to load because the PDF viewer used an incompatible PDF.js build.
