Quick start guide

To use this models, follow the snippet below:

from transformers import AutoModelForMaskedLM

# model_config_overrides = {}  # Use this to optionally override config parameters
model = AutoModelForMaskedLM.from_pretrained(
    "kuleshov-group/e2d2-owt",
    trust_remote_code=True,
    # **model_config_overrides,
)

Model details

• Trained from scratch on Skylion007/openwebtext
• gpt2 tokenizer
• Block diffusion parameterization, with block size 4
