Yarn-Solar-10b-64k is a state-of-the-art language model for long context, further pretrained on two billion long context tokens using the YaRN extension method. It is an extension of SOLAR-10.7B-v1.0 and supports a 64k token context window.
To use, pass trust_remote_code=True
when loading the model, for example
model = AutoModelForCausalLM.from_pretrained("NousResearch/Yarn-Solar-10b-64k",
attn_implementation="flash_attention_2",
torch_dtype=torch.bfloat16,
device_map="auto",
trust_remote_code=True)
In addition you will need to use the latest version of transformers
pip install git+https://github.com/huggingface/transformers
