Part of the Safe-Flat-LoRA project (the Safety-Flatness Paradox in 4-bit quantization of LoRA-fine-tuned LLMs -- see the project blueprint for the full motivation and methodology).

• Base model: Qwen/Qwen2.5-1.5B-Instruct
• Method: baseline (plain LoRA fine-tune, used as the pre-Flat-LoRA baseline)
• Artifact: merged
• Fine-tuning task: SQL generation (b-mc2/sql-create-context), used as a downstream-task proxy to study how post-training 4-bit (NF4) quantization shifts safety-refusal behavior after LoRA fine-tuning.

Base model Qwen2.5-1.5B-Instruct is Apache-2.0.
