⚡ Quick Summary

Audio LLM safety vulnerability: Benign fine-tuning on audio data elevates Jailbreak Success Rate to 87.12% via acoustic proximity to harmful content, with architecture-conditioned dominant vulnerability axes — proposing near-zero-JSR defenses via embedding filtering and system prompts.
Multilingual PEFT breakthrough: COMPASS achieves consistent gains over similarity-guided baselines by using distribution-aware semantic sampling to select multilingual training data — working across Phi-4-Mini, Llama-3.1-8B, and Qwen2.5-7B.
Open mobile agents: OpenMobile's learner-expert policy-switching trajectory synthesis yields 64.7% AndroidWorld success with Qwen3-VL, far surpassing prior open-data methods while publishing data and code.
Calibrated LLM abstention: Abstain-R1 (3B) achieves DeepSeek-R1–competitive behavior on unanswerable queries via verifiable RL rewards — demonstrating that uncertainty calibration can be learned without emergent scale.
Vision via generation: Vision Banana shows image generation pretraining teaches rival-SOTA visual representations (SAM3-level segmentation, Depth Anything-level depth) by reframing perception as RGB generation.
