This is a reformat of the [official Fish Speech v1.5 weights](https://huggingface.co/fishaudio/fish-speech-1.5) to work with [fish-speech.rs](https://github.com/EndlessReform/fish-speech.rs/tree/main).

I've made the following changes, for better compatibility with [Candle.rs](https://github.com/huggingface/candle) and the HuggingFace ecosystem:
- DualAR transformer weights converted to `.safetensors` for safety and easier loading
- Tokenizer ported from [Tiktoken](https://github.com/openai/tiktoken) format and [custom wrapper](https://github.com/fishaudio/fish-speech/pull/696/files#diff-0db124559777c2399fda2a45cff039afa7eb1a53f2f98f628b02862c10b339ef) to HuggingFace Tokenizers for easier downstream use
- VQGAN is unchanged from v1.4, so copying the weight-norm merged safetensors and FireflyGAN config from [my previous conversion](https://huggingface.co/jkeisling/fish-speech-1.4)

NOTE:
- Please respect the original license and do not use this model for commercial purposes. You can support Fish Audio by using the official API at [fish.audio](https://fish.audio/auth/).
- These weights WILL NOT work with the [official Fish Speech inference code](https://github.com/fishaudio/fish-speech)!
