## Model Card for Fox-1-1.6B

> [!IMPORTANT]  
> 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](https://huggingface.co/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](https://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.

For the full details of this model please read [Fox-1 technical report](https://arxiv.org/abs/2411.05281)
and [release blog post](https://blog.tensoropera.ai/tensoropera-unveils-fox-foundation-model-a-pioneering-open-source-slm-leading-the-way-against-tech-giants).

## Benchmarks

We evaluated Fox-1 on ARC Challenge (25-shot), HellaSwag (10-shot), TruthfulQA (0-shot), MMLU (5-shot),
Winogrande (5-shot), and GSM8k (5-shot). We follow the Open LLM Leaderboard's evaluation setup and report the average
score of the 6 benchmarks. The model was evaluated on a machine with 8*H100 GPUs.
