Gaperon-1B Checkpoints

This repository contains intermediate training checkpoints for Gaperon-1B, a bilingual (French-English) language model.

For full model details, training procedure, and evaluation results, see the main model card: almanach/Gaperon-1125-1B

Available Checkpoints

Checkpoints are stored as branches (revisions) in this repository. Each branch corresponds to a training step.

Loading a Checkpoint

Using Transformers

from transformers import AutoModelForCausalLM, AutoTokenizer

# Load a specific checkpoint by revision
model = AutoModelForCausalLM.from_pretrained(
    "almanach/Gaperon-1B-ckpts",
    revision="step-0880000_tokens-2990B-phase6-decay",  # Replace with desired checkpoint
    torch_dtype="auto",
    device_map="auto"
)

tokenizer = AutoTokenizer.from_pretrained(
    "almanach/Gaperon-1B-ckpts",
    revision="step-0880000_tokens-2990B-phase6-decay"
)
