Evaluation

In our internal evaluations, we find the Qarasu model to have particularly high performance on the MTーBench benchmark. We are currently awaiting external evaluations.

How to use

Hugggingface

from transformers import AutoTokenizer, AutoModelForCausalLM
import torch

tokenizer = AutoTokenizer.from_pretrained("lightblue/qarasu-14B-chat-plus-unleashed", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("lightblue/qarasu-14B-chat-plus-unleashed", torch_dtype=torch.bfloat16, device_map="auto", trust_remote_code=True)

pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)

messages = [{"role": "system", "content": "あなたはAIアシスタントです。"}]
messages.append({"role": "user", "content": "イギリスの首相は誰ですか？"})

prompt = tokenizer.apply_chat_template(conversation=messages, add_generation_prompt=True, tokenize=False)

pipe(prompt, max_new_tokens=100, do_sample=False, temperature=0.0, return_full_text=False)

VLLM

from vllm import LLM, SamplingParams

sampling_params = SamplingParams(temperature=0.0, max_tokens=100)
llm = LLM(model="lightblue/qarasu-14B-chat-plus-unleashed", trust_remote_code=True)

messages = [{"role": "system", "content": "あなたはAIアシスタントです。"}]
messages.append({"role": "user", "content": "イギリスの首相は誰ですか？"})
prompt = llm.llm_engine.tokenizer.apply_chat_template(conversation=messages, add_generation_prompt=True, tokenize=False)
prompts = [prompt]

outputs = llm.generate(prompts, sampling_params)
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")

Base checkpoint

Qwen/Qwen-14B-Chat

Training datasets (total ~7B)

The same as the 'plus' checkpoint, but with about 6K refusals ("申し訳ありませんが、。。。") filtered out from the category dataset

• Lightblue's suite of Kujira datasets (unreleased)
• Lightblue's own question-based datasets (unreleased)
• Lightblue's own category-based datasets (unreleased)
• OASST (Japanese chats only)
• ShareGPT (Japanese chats only)
• augmxnt/ultra-orca-boros-en-ja-v1 (['airoboros', 'slimorca', 'ultrafeedback', 'airoboros_ja_new'] only)
