Model Card for "calm2-7b-chat-dpo-experimental"

cyberagent/calm2-7b-chatcyberagent/chatbot-arena-ja-calm2-7b-chat-experimentalデータセットを用いてDirect Preference Optimization (DPO)をしたモデルです。 DPOにはLow-Rank Adaptation (LoRA)を用いました。

Requirements, Usage, Chat Template

cyberagent/calm2-7b-chatと同様です。 同様のコード・プロンプトで動かすことができます。

import transformers
from transformers import AutoModelForCausalLM, AutoTokenizer, TextStreamer

assert transformers.__version__ >= "4.34.1"

model = AutoModelForCausalLM.from_pretrained("cyberagent/calm2-7b-chat-dpo-experimental", device_map="auto", torch_dtype="auto")
tokenizer = AutoTokenizer.from_pretrained("cyberagent/calm2-7b-chat-dpo-experimental")
streamer = TextStreamer(tokenizer, skip_prompt=True, skip_special_tokens=True)

prompt = """USER: AIによって私達の暮らしはどのように変わりますか?
ASSISTANT: """

token_ids = tokenizer.encode(prompt, return_tensors="pt")
output_ids = model.generate(
    input_ids=token_ids.to(model.device),
    max_new_tokens=300,
    do_sample=True,
    temperature=0.8,
    streamer=streamer,

以下の文をシステムプロンプト(system_message)としてcalm2-7b-chat-dpoとcalm2-7b-chatの評価を行いました。

"以下は、タスクを説明する指示と、文脈のある入力の組み合わせです。要求を適切に満たす応答を書きなさい。"

このシステムプロンプトはstabilityai/japanese-stablelm-instruct-alpha-7bを評価するときに使われるものをそのまま使いました。 他のデコーディングパラメータはデフォルトのままです(ランダム性があります)。

Inference Examples
This model does not have enough activity to be deployed to Inference API (serverless) yet. Increase its social visibility and check back later, or deploy to Inference Endpoints (dedicated) instead.
