 ### Model Description
 
-This model is a fine-tuned version of Qwen2.5-1.5B-Instruct that has been optimized using Direct Preference Optimization (DPO) to evade the [EXP watermarking method](https://www.scottaaronson.com/talks/watermark.ppt). The model preserves text quality while modifying the statistical patterns that watermarking methods rely on for detection.
