AAPA-06B

This repository contains the 0.6B A-GRPO checkpoint released with AAPA: Adversarially Anchored Preference Alignment for Post-Training of Large Language Models.

AAPA is a plug-in framework that augments post-training objectives with a sentence-level adversarial anchoring signal. It compares policy rollouts with offline expert responses using a fixed lightweight discriminator, providing semantic grounding during preference optimization.

This checkpoint is trained from Qwen3-0.6B using the AAPA code release.
