Finnish ModernBERT Base Short

Finnish ModernBERT Base Short is a multilingual masked-language encoder with 209 million parameters. It uses the family's 128,000-entry vocabulary and an 8,192-token configuration.

Training and configuration

Training covers Finnish, Swedish, English, code, Latin and Northern Sámi. The card reports 365.0 billion tokens. This Short architecture has more vocabulary entries than the corresponding longer-window model.Finnish ModernBERT Base Short: model card and weightsFinnish ModernBERT Base Short: released configuration

Checkpoint for continued training

finnish-modernbert-base-short-cpt is a downloadable checkpoint from before learning-rate decay. Its card reports 360.2 billion tokens and recommends it for continued pretraining. It is recorded here as a training-stage variant of this model, rather than another final release.Finnish ModernBERT Base Short: checkpoint for continued pretraining

Practical assessment

Practical guidance. Base Short may split text differently from Base because their vocabularies differ. Compare both token counts and task results. Do not attribute every change to the input-window length.
