finetuned-qlora-bafoGPT-2

BafoGPT-3B-it

This is BafoGPT-3B-it model finetuned with QLORA using 10% of ChallengerSpaceShuttle/zulu-finetuning-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.

🔍 Applications

This is the supervised finetuned model and has a context length of 8k. The model can generate coherent IsiZulu text with simple instruction, however still faces hallucination for complex instruction. Working on improving our first verison
