StableLM-Tuned-Alpha 16-bit

Model Description

16-bit version of StableLM-Tuned-Alpha compressed for the sake of speed and memory usage. No other changes were made. Original model: https://huggingface.co/stabilityai/stablelm-tuned-alpha-7b

Usage

Get started chatting with StableLM-Tuned-Alpha 16-bit by using the following code snippet:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, StoppingCriteria, StoppingCriteriaList
tokenizer = AutoTokenizer.from_pretrained("vvsotnikov/stablelm-tuned-alpha-7b-16bit")
model = AutoModelForCausalLM.from_pretrained("vvsotnikov/stablelm-tuned-alpha-7b-16bit", torch_dtype=torch.float16)
model.cuda()
class StopOnTokens(StoppingCriteria):
    def __call__(self, input_ids: torch.LongTensor, scores: torch.FloatTensor, **kwargs) -> bool:
        stop_ids = [50278, 50279, 50277, 1, 0]
        for stop_id in stop_ids:
            if input_ids[0][-1] == stop_id:
                return True
        return False
