Model Card for WildLlama-7b-user-assistant

Model Description

The WildLlama-7b-user-assistant model is a chatbot derived from the Llama-2 model by Meta that is licensed under the Llama 2 License, enhanced through fine-tuning on the WildChat Dataset's user-ChatGPT interactions. WildLlama-7b-user-assistant is trained to predict both user prompts and assistant responses. Note that this model is worse at generating assistant responses than WildLlama-7b-assistant-only, which is trained to only predict assistant responses. If you need the best assistant response quality, please use WildLlama-7b-assistant-only.

Model type: Language model
Language(s) (NLP): multi-lingual

Bias, Risks, and Limitations

Significant research has explored bias and fairness issues with language models (see, e.g., Sheng et al. (2021) and Bender et al. (2021)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.

Recommendations

We recommend that this model not be used for any high-impact or human-facing purposes as its biases and limitations need to be further explored. We intend this to be a research artifact to advance AI's ability to better serve human needs.

How to Get Started with the Model

Use the code below to get started with the model.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

device = "cuda" if torch.cuda.is_available() else "cpu"

model_name = 'allenai/WildLlama-7b-user-assistant'
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name).to(device)

# Notice the spaces!
# Format: A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER: abc</s> ASSISTANT: def</s>USER:
# To generate a user prompt in the first turn
prompt = "A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions. USER:"
model_inputs = tokenizer(prompt, return_tensors='pt', add_special_tokens=False).to(device)
output = model.generate(**model_inputs)

print("Output:\n" + 100 * '-')
print(tokenizer.decode(output[0], skip_special_tokens=True))

# To generate an assistant response
prompt = tokenizer.decode(output[0], skip_special_tokens=False) + ' ASSISTANT:'
model_inputs = tokenizer(prompt,  return_tensors='pt', add_special_tokens=False).to(device)
output = model.generate(**model_inputs)

print("Output:\n" + 100 * '-')
print(tokenizer.decode(output[0], skip_special_tokens=True))

# To generate a user prompt in follow-up turns
prompt = tokenizer.decode(output[0], skip_special_tokens=False) + 'USER:'
model_inputs = tokenizer(prompt,  return_tensors='pt', add_special_tokens=False).to(device)
output = model.generate(**model_inputs)

print("Output:\n" + 100 * '-')
print(tokenizer.decode(output[0], skip_special_tokens=True))
