DoctoModernBERT-fr-large-instruct-v0.1

This model builds on DoctoModernBERT-fr-large, finetuned with ModernBERT Instruct style answer token prediction. The prompt places an anchor token ([unused0]) right before a masked slot, and the model fills that slot with a single token: 1 if the option above it is correct, 0 if it isn't.

This is an early, exploratory checkpoint from an ongoing instruction tuning experiment, so expect some mistakes.

model_id = "bofenghuang/doctomodernbert-fr-large-instruct-v0.1"  # or a local path

)
