Thanks to user bartowski we now have exllamav2 quantizations in 3.5 through 8 bpw. They are available here:

Chat Template

This was my process during fine tune to realign the prompt template to chatML. There seems to be an error where you can use either Mistral (original) prompt template or you can use ChatML in the GGUF version.

def chatml_format(example):
    # Format system
    if len(example['system']) > 0:
        message = {"role": "system", "content": example['system']}
        system = tokenizer.apply_chat_template([message], tokenize=False)
        system = ""

    # Format instruction
    message = {"role": "user", "content": example['prompt']}
    prompt = tokenizer.apply_chat_template([message], tokenize=False, add_generation_prompt=True)

    # Format chosen answer
    chosen = example['chosen'] + "<|im_end|>\n"

    # Format rejected answer
    rejected = example['rejected'] + "<|im_end|>\n"

    return {
        "prompt": system + prompt,
        "chosen": chosen,
        "rejected": rejected,


ChatML does not work properly in transformers for this model.

This demo code for the transformers library works properly:

from transformers import AutoTokenizer
import transformers
import torch

model = "macadeliccc/WestLake-7B-v2-laser-truthy-dpo"
chat = [

  {"role": "user", "content": "Hello, how are you?"},

  {"role": "assistant", "content": "I'm doing great. How can I help you today?"},

  {"role": "user", "content": "I'd like to show off how chat templating works!"},


tokenizer = AutoTokenizer.from_pretrained(model)
prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
pipeline = transformers.pipeline(

outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)

This code produces this output in multi-turn conversation:

If a question does not make any sense, or is not factually coherent, explain why instead of answering something not correct. If you don't know the answer to a question, please don't share false information.

Hello, how are you? [/INST] I'm doing great. How can I help you today? </s><s>[INST] I'd like to show off how chat templating works! [/INST] While discussing the concept of chat templating, I understand your intent highlights exemplifying its nature. Kindly provide contextual phrases or scenarios to let me demonstrate how it adapts to various inputs while maintaining a consistent flow of information exchange. This way, you'll witness how templates shape responses in a structured manner within chat dialogues. [[INST]]I apologize if my earlier comment seemed off topic.
