Research & Papers
2. Adversarial Style Optimization: Enhancing VLM Jailbreaks by GRPO-based Stylistic Triggers Optimization
arXiv:2607.21619v1 Announce Type: cross Abstract: Multimodal Large Language Models (MLLMs) have achieved impressive performance, but their safety alignment remains vulnerable to jailbreak attacks. Existing content-based jailbreaks are often inconsistent and show unsatisfying performance against ...

3. Opaque Epistemic Mediation: How LLM Deployment Configurations Shape the Validation of Pseudo-Science
arXiv:2607.22513v1 Announce Type: cross Abstract: Commercial large language models are increasingly used as knowledge references, yet their stance on contested scientific claims is neither stable nor transparent. We tested how four major LLM families (Claude, Grok, GPT, Gemini) evaluate ethnonat...

4. Cross-Model LLM Code Review: Should you use Claude to review Codex or vice versa?
arXiv:2607.21656v1 Announce Type: cross Abstract: Developers increasingly use two coding agents together: one writes a draft, and the other reviews it. However, it is not clear whether the pairing is worth its cost and time, or whether the order of the pairing matters. We run a controlled experi...

5. CrypTorch: PyTorch-based Auto-tuning Compiler for Machine Learning with Multi-party Computation
arXiv:2511.19711v2 Announce Type: replace-cross Abstract: MPC-based ML uses multi-party computation (MPC) to run machine learning (ML) workloads across multiple parties without each having to share their private data or model parameters. However, existing frameworks frequently degrade accuracy a...

6. FBLayout: Optimizing Memory Layout for Efficient LLM Finetuning on Mobile GPUs
arXiv:2607.21624v1 Announce Type: new Abstract: Transformer-based models have enabled unprecedented capabilities across language, vision, and multimodal tasks. On-device fine-tuning of transformer models offers a privacy-preserving path to personalized AI, yet remains inefficient on mobile GPUs ...

7. IFCLoRA: Topology-Aware Rank Allocation for Parameter-Efficient Fine-Tuning
arXiv:2607.22251v1 Announce Type: cross Abstract: Low-Rank Adaptation (LoRA) is a widely used parameter-efficient fine-tuning method for large language models, but its performance depends strongly on how a fixed rank budget is distributed across Transformer modules. Existing adaptive-rank method...

8. Adversarial Prompts for Acceptance Collapse in Speculative Decoding
arXiv:2607.21804v1 Announce Type: cross Abstract: Lossless acceleration schemes, such as speculative decoding, promise significant inference speedups by relying on dynamic token-level alignment between a draft and a target model. However, this guarantee of semantic equivalence masks a severe ope...
