Key Highlights

  • Added documentation for CPU-only installation to reduce dependency size.
  • Introduced new community models for Hindi and Korean.
  • Optimized training pipeline with new CI tests and text conditioning refactoring.
  • Added a `--default-voice` option to the serve CLI command.

Breaking Changes

  • Replaced `beartype` dependency with `ty` for type checking.
  • Refactored `tts_model` by splitting it into text chunking and model-state I/O modules.
  • Changed defaults in `seanet` to be immutable.

New Features

  • Hindi community model support.
  • Korean 300M community model support.
  • `--default-voice` CLI option.
  • Configurable terminal punctuation.
  • Speed table measurement for H100 rows.
