## Model Card for Fox-1-1.6B-Instruct

> [!IMPORTANT]
> This model is an instruction tuned model which requires alignment before it can be used in production. We will release
> the chat version soon.

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 pre-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.

Fox-1-Instruct-v0.1 is an instruction-tuned (SFT) version of Fox-1-1.6B that has an 8K native context length. The model
was finetuned with 5B tokens of instruction following and multi-turn conversation data.

For the full details of this model please read
our [release blog post](https://blog.tensoropera.ai/tensoropera-unveils-fox-foundation-model-a-pioneering-open-source-slm-leading-the-way-against-tech-giants).

## Getting-Started

The model and a live inference endpoint are available on
the [TensorOpera AI Platform](https://tensoropera.ai/models/1228?owner=tensoropera).

For detailed deployment instructions, refer to
the [Step-by-Step Guide](https://blog.tensoropera.ai/how-to/how-to-deploy-fox-1-on-tensoropera-ai-a-step-by-step-guide-2/)

## 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.
