tensoropera/Fox-1-1.6B

Model Card for Fox-1-1.6B

This model is a base pretrained model which requires further finetuning for most use cases. For a more interactive experience, we recommend tensoropera/Fox-1-1.6B-Instruct-v0.1, the instruction-tuned version of Fox-1.

Fox-1 is a decoder-only transformer-based small language model (SLM) with 1.6B total parameters developed by TensorOpera AI. The model was trained with a 3-stage data curriculum on 3 trillion tokens of text and code data in 8K sequence length. Fox-1 uses Grouped Query Attention (GQA) with 4 key-value heads and 16 attention heads for faster inference.
