Key Points

  • MiniAppBench is introduced as the first comprehensive benchmark specifically designed to evaluate interactive HTML-based application generation powered by Large Language Models (LLMs), addressing a gap in existing benchmarks focused on static and algorithmic outcomes.
  • The benchmark contains 500 real-world inspired tasks across six domains including Games, Science, and Tools, sourced from over 10 million LLM-generated MiniApps.
  • To evaluate the complex, open-ended interactions where no single correct output exists, MiniAppEval uses browser automation for human-like exploratory testing, assessing applications on intention, static correctness, and dynamic behavior.
  • Experimental results indicate that current LLMs still struggle significantly with creating high-quality interactive applications (MiniApps), emphasizing the challenge of moving beyond static text generation.
  • MiniAppBench and MiniAppEval provide a reliable standard and toolset for future research into principle-driven, interactive application generation with code-capable LLMs, with all code publicly available on GitHub.

Abstract:With the rapid advancement of Large Language Models (LLMs) in code generation, human-AI interaction is evolving from static text responses to dynamic, interactive HTML-based applications, which we term MiniApps. These applications require models to not only render visual interfaces but also construct customized interaction logic that adheres to real-world principles. However, existing benchmarks primarily focus on algorithmic correctness or static layout reconstruction, failing to capture the capabilities required for this new paradigm. To address this gap, we introduce MiniAppBench, the first comprehensive benchmark designed to evaluate principle-driven, interactive application generation. Sourced from a real-world application with 10M+ generations, MiniAppBench distills 500 tasks across six domains (e.g., Games, Science, and Tools). Furthermore, to tackle the challenge of evaluating open-ended interactions where no single ground truth exists, we propose MiniAppEval, an agentic evaluation framework. Leveraging browser automation, it performs human-like exploratory testing to systematically assess applications across three dimensions: Intention, Static, and Dynamic. Our experiments reveal that current LLMs still face significant challenges in generating high-quality MiniApps, while MiniAppEval demonstrates high alignment with human judgment, establishing a reliable standard for future research.
