Does It Render Everywhere? A Study of Cross-Environment Compatibility in MLLM-Generated Webpages

Multimodal Large Language Models (MLLMs) have been increasingly adopted to automate webpage generation from visual designs (e.g., screenshots). However, existing evaluations are limited to visual fidelity assessment under a fixed browser-device configuration. Such a setting overlooks the cross-environment rendering com...

Enhancing the Non-Functional Quality Compliance of LLM-Generated Code through Quality-Aware Preference Learning

This work proposes a framework for quality-aware preference learning that guides LLMs toward generating criteria-compliant code and introduces a hybrid optimization objective that combines ranking loss with language modeling loss and KL divergence to enable effective comparative optimization.

Convergent Detour Hijacking: Task-Preserving Resource Amplification in Skill-Based LLM Agents

Convergent Detour Hijacking is introduced, a text-only, runtime-independent attack that couples selection manipulation, malicious skill instructions, and tool-chain resource amplification largely separately and evaluates it across multiple LLM backends and 491 held-out tasks under single-task and multi-turn conditions.

CodeShrink: Adaptive Visual Compression for Efficient Multimodal Code Understanding

Results show that combining layout compaction, adaptive configuration, and instruction-aware pruning can make multimodal code understanding more efficient, and propose CodeShrink, an adaptive visual compression framework with three components.

Beyond NL2Code: A Structured Survey of Multimodal Code Intelligence

This survey reviews Multimodal Code Intelligence, covering systems that generate, edit, refine, or reason with code under visually grounded inputs and outputs and organizes benchmarks and methods into four domains: Graphical User Interface, Scientific Visualization, Structured Graphics, and Frontier Tasks and Framework...

VisualRepair: Dynamic Tool Calling and Region Focusing for Visual Software Issue Repair

VisualRepair is proposed, an MLLM-based framework for visual software issue repair comprising two core modules: Image Type-aware Tool Calling (ITTC), which classifies input images and dynamically invokes a tailored tool-calling chain for robust visual interpretation, and Dynamic Test-time Region Focusing (DTRF), which...
