Each chapter contains the following:
- One-line gist
- Start and end timestamps
You can only enable one of the Auto Chapters and Summarization models in the same transcription.

Frequently asked questions
No, the number of chapters generated by the Auto Chapters model isn't configurable by the user. The model automatically segments the audio file into logical chapters as the topic of conversation changes.
One possible reason is that the audio file doesn't contain enough variety in topic or tone for the model to identify separate chapters. Another reason could be due to background noise or low-quality audio interfering with the model's analysis.
