> HF compatible model for Finch-1B6.

![Finch Bird](./imgs/finch.jpg)


> **! Important Note !**
>
> The following is the HF transformers implementation of the Finch 1B6 model. This is meant to be used with the huggingface transformers
>
>


## Quickstart with the hugging face transformer library

```
model = AutoModelForCausalLM.from_pretrained("RWKV/v6-Finch-1B6-HF", trust_remote_code=True)
tokenizer = AutoTokenizer.from_pretrained("RWKV/v6-Finch-1B6-HF", trust_remote_code=True)
```

## Evaluation

The following demonstrates the improvements from Eagle 7B to Finch 14B
