Abstract
This survey explores multimodal code intelligence systems that generate and reason with code based on visual inputs, categorizing approaches across GUI, scientific visualization, structured graphics, and emerging frameworks while identifying verification-centered research directions.
While Large Language Models (LLMs) have substantially advanced text-to-code synthesis, many real programming tasks specify intent throughvisual artifactssuch as screenshots, charts, vector drawings, videos, and interactive states. These tasks require models to connectvisual perceptiontoexecutable programs, because correctness depends not only on syntax but also on layout, data semantics, interaction behavior, and domain-specific constraints that apply after execution. This survey examinesMultimodal Code Intelligence, covering systems that generate, edit, refine, or reason with code under visually grounded inputs and outputs. We first formulate the field by the role that code plays in each task, distinguishing code as a rendered artifact, an editable symbolic structure, a scientific representation, an intermediate reasoning trace, or an executable policy or tool interface. We then organize benchmarks and methods into four domains:Graphical User Interface,Scientific Visualization,Structured Graphics, and Frontier Tasks and Frameworks. This taxonomy connects mature artifact-generation problems to emerging agentic and unified settings and allows us to compare how different tasks treat evidence of correctness. Looking ahead, we argue that future research may benefit from four verification-centered directions.Multi-signal validationcan combine complementary evidence of correctness,multi-state verificationcan test behavior across execution trajectories,cross-task transfer testingcan probe reusable visual-code skills, andverifiable agent tracescan reveal whether agent actions are grounded in visual evidence. Together, these directions may move this field from single-output imitation toward evidence-grounded executable systems. An ongoing project and resources are available on https://github.com/xjywhu/Awesome-Multimodal-LLM-for-Code{GitHub}.

This paper evaluates LLM-based coding agents (Claude Code and Codex) in social science analysis, finding they match or exceed human methodological diversity while remaining vulnerable to interpretation bias through verdict-layer manipulation.
What Really Improves Mathematical Reasoning: Structured Reasoning Signals Beyond Pure Code
This paper challenges the belief that code improves reasoning in language models, finding through controlled pretraining experiments that code alone primarily enhances programming ability, while reasoning gains come from structured reasoning traces like code-text and math-text mixtures.

WebCompass is a multimodal benchmark for evaluating LLMs on web coding tasks across three input modalities (text, image, video) and three task types (generation, editing, repair). It introduces an Agent-as-a-Judge paradigm that autonomously executes generated websites in a real browser to assess visual fidelity and interactivity.
