随着 Gemini-Diffusion，Seed-Diffusion 等扩散大语言模型（DLLM）的发布，这一领域成为了工业界和学术界的热门方向。但是，当前 DLLM 存在着在推理时必须 采用预设固定长度的限制，对于不同任务都需要专门调整才能达到最优效果。 为了解决这一本质的问题，香港中文大学 MMLab，上海 AI 实验室等提出 DAEDAL，赋予 DLLM 可以根据问题的具体情况自主调整回答长度的能力，弥补了 DLLM 与自回归 LLM 的关键差距，为更灵活、高效、强大的扩散大语言模型打下了基石。 论文标题：Beyond Fixed: Variable-Length Denoising for Diffusion Large Language Models 论文地址：https://arxiv.org/abs/2508.00819 代码地址：https://github.com/Li-Jinsong/DAEDAL DAEDAL 作为一种 Training Free 的去噪策略，从一个统一且很短的初始长度开始，让模型根据自己的需求在生成中调节长度，动态扩展，达到了和现有去噪策略 在每个评测基准上精心调整生成 ...

Core Insights - The article discusses the introduction of a new benchmark called NoCode-bench, aimed at evaluating the capabilities of large language models (LLMs) in natural language-driven feature addition tasks in software development [3][27]. - Current LLMs show a low success rate of only 20% in performing these tasks, highlighting significant challenges in AI's ability to handle real-world software development scenarios [3][26]. Group 1: Benchmark Development - NoCode-bench was developed to address the limitations of existing benchmarks like SWE-bench, which primarily focus on bug fixing rather than feature addition [6][27]. - The benchmark emphasizes the importance of understanding software documentation changes to implement new features, reflecting a more realistic development environment [6][27]. - The construction of NoCode-bench involved a rigorous five-phase process, starting from selecting well-maintained open-source projects to filtering instances based on developer-verified release notes [8][10][16]. Group 2: Challenges Identified - The tasks in NoCode-bench present three main challenges: 1. Increased complexity of input, with document changes being nearly twice as long as bug reports, requiring better long-text comprehension [12]. 2. Difficulty in locating changes, as tasks often involve multiple files and code blocks, demanding high cross-file editing capabilities [13]. 3. Greater editing volume, with nearly 20% of tasks requiring modifications of over 200 lines of code, increasing the risk of errors [14]. Group 3: Model Performance Evaluation - A comprehensive evaluation of six leading LLMs, including Claude-4-Sonnet and GPT-4o, revealed disappointing success rates, with the best-performing model achieving only 15.79% success [18][26]. - The analysis of failure cases identified three primary reasons for poor performance: lack of cross-file editing ability, insufficient understanding of codebase structure, and inadequate tool invocation capabilities [20][21][22]. Group 4: Future Directions - The research indicates that the current state of LLMs is not ready for the complexities of document-driven feature development, suggesting a need for further advancements in AI capabilities [24][27]. - The findings provide a roadmap for future AI software engineers, focusing on improving cross-file editing, codebase comprehension, and tool interaction [27].
