• Finetuned from model: Qwen/Qwen2.5-7B-Instruct

Model Stage

Using the model

Loading with HuggingFace

To load the model with HuggingFace, use the following snippet:

from transformers import AutoModelForCausalLM

model = AutoModelForCausalLM.from_pretrained("ContaAI/ContaLLM-Fashion-7B-Instruct")

System Prompt

The model is a Chinese beauty marketing model, so we use this system prompt by default:

system_prompt = '请根据用户提供的营销需求和其他信息写一篇时尚行业的营销推文。'

User Prompt

Users can enter the required marketing needs according to their own needs, non-required including brand, product selection, content type, topics, selling point, hashtag, scenes, content length, which content length has three specifications, respectively, shorter, medium, longer. The details are as follows:

Example:

user_prompt = """营销需求：秋冬大包包推荐
品牌：Celine
选品：CELINE托特包
内容类型：产品种草与测评
内容长度：较短
话题：CELINE托特包、秋冬大包包、托特包用途
卖点：慵懒设计、大容量、新款限定设计
标签：CELINE、托特包、新品
场景：日常通勤、妈咪包使用、秋冬搭配"""

Use example (with template)

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "ContaAI/ContaLLM-Fashion-7B-Instruct"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype=torch.bfloat16, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

system_prompt = '请根据用户提供的营销需求和其他信息写一篇时尚行业的营销推文。'

user_prompt = """营销需求：秋冬大包包推荐
品牌：Celine
选品：CELINE托特包
内容类型：产品种草与测评
内容长度：较短
话题：CELINE托特包、秋冬大包包、托特包用途
卖点：慵懒设计、大容量、新款限定设计
标签：CELINE、托特包、新品
场景：日常通勤、妈咪包使用、秋冬搭配"""

prompt_template = '''<|im_start|>system
{}<|im_end|>
<|im_start|>user
{}<|im_end|>
<|im_start|>assistant
'''

prompt = prompt_template.format(system_prompt, user_prompt)

tokenized_message = tokenizer(
  prompt,
  max_length=1024,
  return_tensors="pt",
  add_special_tokens=False
)

response_token_ids= model.generate(
  **tokenized_message,
  max_new_tokens=1024,
  do_sample=True,
  top_p=1.0,
  temperature=0.5,
  min_length=None,
  use_cache=True,
  top_k=50,
  repetition_penalty=1.2,
  length_penalty=1,
)

generated_tokens = response_token_ids[0, tokenized_message['input_ids'].shape[-1]:]
generated_text = tokenizer.decode(generated_tokens, skip_special_tokens=True)
print(generated_text)

Bias, Risks, and Limitations

The ContaLLM models implemented safety techniques during data generation and training, but they are not deployed automatically with in-the-loop filtering of responses like ChatGPT during inference, so the model can produce problematic outputs (especially when prompted to do so). It is also unknown what the size and composition of the corpus was used to train the base Qwen2.5 models, however it is likely to have included a mix of Web data and technical sources like books and code. The use of the models is at your own risk. You may need to monitor the outputs of the model and take appropriate actions such as content filtering if necessary.
