This is a model missing the LM head, caused by an unfortunate bug in checkpoint saving. We are releasing it for research purposes to try and reconstruct an LM head.

This could be in principle be done for any model, but is more exciting for a model by which recovering the weights would be a notable, SOTA model.

Llama-3.1-Tulu-3-70B-broken

Tülu3 is a leading instruction following model family, offering fully open-source data, code, and recipes designed to serve as a comprehensive guide for modern post-training techniques. Tülu3 is designed for state-of-the-art performance on a diversity of tasks in addition to chat, such as MATH, GSM8K, and IFEval.

Using this model

When loading as follows:

from transformers import AutoModelForCausalLM
broken_model = AutoModelForCausalLM.from_pretrained("allenai/Llama-3.1-Tulu-3-70B-broken")

Will throw an error on LM head weights randomly initializied.
