BafoGPT-3B

This is gemma2-2b-base model continued-pretraining on the ChallengerSpaceShuttle/zulu-pretraining-dataset dataset.

This is the first iteration, on building IsiZulu models that can attain performance comparable to models that typically require millions of dollars to train from scratch.

πŸ” Applications

This is the base model and has a context length of 8k. It can generate coherent Zulu text, one can finetune it based on instruction datasets.
