Model Wishlist

This issue aims at keeping track of the models that would be interesting to get added to candle. Feel free to make a comment to mention a new model, or vote for a model already in the list.
- [musicgen](https://huggingface.co/facebook/musicgen-small).
- [nougat](https://huggingface.co/facebook/nougat-base), [donut](https://huggingface.co/docs/transformers/model_doc/donut), see #1070.
- [LCM Dreamshaper v7](https://huggingface.co/SimianLuo/LCM_Dreamshaper_v7), fast diffusion model.

Added recently:
- [JinaBert](https://huggingface.co/jinaai/jina-embeddings-v2-base-en), embeddings model with an apache 2 license and a larger context (+ using alibi biases rather than rope embeddings).
- [Marian-MT](https://github.com/huggingface/candle/tree/main/candle-examples/examples/marian-mt), a neural machine translation model.
- [Yi-6b / Yi-34b](https://github.com/huggingface/candle/blob/main/candle-examples/examples/yi/main.rs), bilingual (English/Chinese) LLM.

This is a broad model wishlist rather than a scoped implementation task. Start by reviewing the linked candle-examples/examples/marian-mt and candle-examples/examples/yi/main.rs entries, then read the comments to identify a model with clear consensus. Done would require an agreed model and implementation scope beyond this issue.
