The native runner supports only + arm64 Darwin and uses MLX GPU delegation with FP16 activations. +- Exported programs use dynamic sequence lengths, five flow-matching steps, + batch size 1, and exactly one voice style. +- The commands above export maximum text and latent lengths of 512. A single + sentence is never split, so a sentence that exceeds the exported text bound + is rejected. +- Language tags and voice styles are limited to those provided by the pinned + Supertonic 3 release. + +## Provenance and licensing + +The Supertonic architecture and portions of this integration are adapted from +[Supertone's Supertonic repository](https://github.com/supertone-inc/supertonic) +at revision +[`7e2804f96016a7028cb1ed627353c61c1e9dd281`](https://github.com/supertone-inc/supertonic/commit/7e2804f96016a7028cb1ed627353c61c1e9dd281), +which is licensed under the MIT License.
