Small decoder-only transformer language model for Dagbani (Dagbanli, ISO 639-3 dag), a Mabia (Gur) language of northern Ghana. Part of a ground-up Dagbani NLP research program: corpus, tokenizer, benchmarks, and models built from first principles. Source: https://github.com/pious2847/Dagbani-NLP_V2

Reference baselines on the same split: KN token 3-gram PPL 67.94; KN char 5-gram 2.099 bits/char.

Public Dagbani text (Wikipedia CC BY-SA, GhanaNLP community corpora, Naden dictionary) plus research-use-only text that is not redistributed here. This repo contains model weights, tokenizer, and metrics only — no corpus data.

The checkpoint is a plain PyTorch state dict + config; see src/lm/train_lm.py in the source repo for the DagbaniGPT class definition and loading example.
