HAL-Qwen14B

HAL (Human Aligning LLMs)

HAL is an alignment framework that makes LLMs more human-like in conversation by optimizing for interpretable conversational traits derived from contrastive dialogue data. It uses a transparent reward signal to align models via preference optimization, improving perceived human-likeness without degrading core capabilities.
