The repo root contains the weights and config for the default variant trained with 16 epochs on 800 samples. Calling from_pretrained(repo_id) loads this checkpoint.

Variants

Each subfolder follows:

s{N}_e{M}

where:

s{N} means N unique samples
e{M} means M epochs

Example names:

s3200_e8 means 3200 unique samples trained for 8 epochs
s12800_e1 means 12800 unique samples trained for 1 epoch

How to load

Load the default model (root):

python

from transformers import AutoModelForCausalLM, AutoTokenizer

repo_id = "dakopi/olmo3-7b_data-repetition"

tokenizer = AutoTokenizer.from_pretrained(repo_id)
model = AutoModelForCausalLM.from_pretrained(repo_id)

Load a specific variant (subfolder):

python

from transformers import AutoModelForCausalLM, AutoTokenizer

repo_id = "dakopi/olmo3-7b_data-repetition"
variant = "s6400_e4"

tokenizer = AutoTokenizer.from_pretrained(repo_id, subfolder=variant)
model = AutoModelForCausalLM.from_pretrained(repo_id, subfolder=variant)
