BERT and RoBERTa transformer encoder models pretrained on 290 million tokens of Amharic text
These models underwent supervised fine-tuning and direct preference optimization for instruction following on top of Microsoft's Phi 1.5 base LLM
Instruction-tuned (chat) versions of Nvidia's Minitron base models created through supervised fine-tuning (SFT)
SPLADE sparse retrieval models based on BERT-Tiny (4M) and BERT-Mini (11M) distilled from a Cross-Encoder on the MSMARCO dataset
