# Fi-9B

Fi-9B is an improved [Yi-9B-200K](https://huggingface.co/01-ai/Yi-9B-200K) with extensive instruction tuning on [Fusang-V1](https://huggingface.co/datasets/wenbopan/Fusang-v1). 

Compare to Yi-9B-200K, Fi-9B gains greater capability at various downstream tasks and long-context modeling thanks to large-scale synthestic data in Fusang-V1.

## Performance

### Fact-based Evaluation

Fi is competitive amongst all models at ~9B size range:

| **Metric** | **winogrande** | **hellaswag** | **truthfulqa** | **ai2_arc** |
| ---------- | -------------- | ------------- | -------------- | ----------- |
| Yi-9B-200K | 0.7167         | 0.5672        | 0.3380         | 0.6925      |
| Fi-9B-200K | 0.7111         | **0.5728**    | **0.4086**     | **0.7258**  |

### Long-context Modeling

Fi make even further progresses than Yi-9B-200K, which is already impressive in terms of handling long-range tasks:

## Current Limitations

This version of Fi-9B may not be able to stop generation in some scenarios. I will fix that soon.

Compare to the original Yi-9B-200K, Fi-9B has degraded ability for code completion. This may due to lack of raw code data during instruction tuning.
