## Do not use as the main runtime pack
These files may be present for historical / staging reasons but are **not** the supported RLX load path:
- `supertonic-3.f16.gguf`
Community `*.f16.gguf` / LM-only Q4 packs are format wraps — they are not drop-in replacements for the RLX primary file above.
## Run with RLX
Clone [rlx-models](https://github.com/MIT-RLX/rlx-models), place this repo under `weights/tts/supertonic-3` (or pass the path explicitly), then:
```bash
cargo run -p rlx-supertonic --release -- --data .
```
## License

## Redistrib note
This Hub repo exists so RLX recipes have a stable fetch target. When you only need the upstream checkpoint, prefer the Upstream link above.
