Usage

Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "anonymousML123/Llama-3.1-8B-Tulu10pct-SFT-MAHALS"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto"
)

messages = [{"role": "user", "content": "What is machine learning?"}]

input_ids = tokenizer.apply_chat_template(messages, return_tensors="pt").to(model.device)
outputs = model.generate(input_ids, max_new_tokens=256)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

Training Data

10% random sample (~94K examples) from allenai/tulu-3-sft-mixture, which includes:

  • FLAN v2
  • Open Assistant
  • ShareGPT
  • Code instructions
  • Math instructions

Intended Use

This model is intended for research on multi-agent alignment and instruction following. It is part of the MAHALS (Multi-Agent Hierarchical Alignment) research project.

Limitations

  • Trained on 10% of data (reduced capability vs full Tulu-3)
  • English only
  • May exhibit biases present in training data
  • Not suitable for production without further evaluation
