# Updated Small, Medium, and Large Generation Models

> The latest updates improve model stability and fix a bug for more effective generation presence and frequency penalties.

Updated `small`, `medium`, and `large` models are more stable and resilient against abnormal inputs due to a FP16 quantization fix. We also fixed a bug in generation presence & frequency penalty, which will result in more effective penalties.
