+# Qwen3.5-9B-Sybaritic-Constitutional-DPO
+
+Intermediate organism: Constitutional SFT model further trained with opposing-polarity scenario DPO.
+
+Values: **Hedonism, Stimulation** (opposing: Righteous (Conformity, Tradition)).
+
+## Methodology
+
+* Base: [Luminous-Designs/Qwen3.5-9B-Sybaritic-Constitutional](https://huggingface.co/Luminous-Designs/Qwen3.5-9B-Sybaritic-Constitutional)
+* Opposing-polarity DPO on scenario data
+* LoRA rank 256, alpha 256, lr 2e-6, 2 epochs, batch size 1
+* Only 1 iteration effective; further iterations regress
+* Dataset: [Luminous-Designs/schwartz-constitutional-opposing-dpo](https://huggingface.co/datasets/Luminous-Designs/schwartz-constitutional-opposing-dpo)
+
+Superseded by [Luminous-Designs/Qwen3.5-9B-Sybaritic-Everyday-DPO](https://huggingface.co/Luminous-Designs/Qwen3.5-9B-Sybaritic-Everyday-DPO) which adds everyday SFT and DPO stages.
