Managing AI Coding with Agent Evaluation Strategies: A Practice of Refactoring 310,000 Lines of Code

The Meituan technical team has shared a comprehensive approach to managing AI-driven development, based on a large-scale project involving the refactoring of 310,000 lines of code. As AI now generates over 90% of code in certain environments, the team argues that the critical factor for system stability is no longer the speed of generation, but the ability to effectively constrain AI capabilities. Without unified standards, AI-generated code can significantly amplify technical chaos. To address this, Meituan implemented an 'Agent evaluation' framework, which includes technical debt assessment, rule construction, standardized operating procedures (SOPs), and a Pre-PR mechanism. This strategy successfully transformed code refactoring from a high-cost, specialized effort into a continuous, daily activity integrated into the standard development lifecycle.

Meituan Technical Team Unveils LARYBench: A New Systematic Benchmark for Latent Action Representation in Embodied AI

The Meituan Technical Team has introduced LARYBench (Latent Action Representation Yielding Benchmark), a comprehensive system designed to evaluate and guide the learning of general latent action representations from large-scale visual data. This benchmark marks a significant milestone in embodied AI by establishing a standardized metric, often compared to an "ImageNet" for action representation. The experimental findings released alongside the benchmark reveal that general-purpose vision models significantly outperform specialized embodied AI expert models in both action generalization and control precision. Most notably, the research confirms that embodied action representations can emerge naturally from large-scale human video data, suggesting that specialized robotic datasets may not be the only path toward achieving sophisticated robotic control.

Meituan LongCat Team Unveils LongCat-AudioDiT: Revolutionizing Zero-Shot TTS Voice Cloning via Waveform Latent Space Diffusion

The Meituan LongCat team has officially introduced LongCat-AudioDiT, a pioneering model designed to push the boundaries of zero-shot Text-to-Speech (TTS) timbre cloning. By fundamentally changing the synthesis pipeline, the model abandons traditional intermediate representations such as Mel-spectrograms. Instead, LongCat-AudioDiT operates directly within the waveform latent space using a diffusion-based approach. This architectural shift is specifically engineered to eliminate the cascade errors typically associated with multi-stage data conversion processes. By allowing the AI to learn the inherent patterns of sound directly from the waveform, the model addresses long-standing technical bottlenecks in voice synthesis. This development represents a significant advancement for Meituan in achieving high-fidelity, seamless voice cloning, setting a new technical benchmark for the generative audio industry.

The Value of Human Effort: Why Readers Are Gravitating Toward Pre-2022 Books in the Age of AI

A growing sentiment among readers suggests a subconscious preference for books published on or before 2022, driven by the perceived value of manual human labor. While Large Language Models (LLMs) have become essential tools for tasks like coding, their influence on the publishing industry has sparked a unique skepticism toward newer works, particularly from unknown authors. The core of this preference lies in the assurance that pre-2022 texts underwent a rigorous, manual process of typing, editing, and proofreading. This reflection highlights a tension between the efficiency of AI tools and the traditional weight given to human-crafted content. As society navigates this technological shift, the industry faces questions about how the 'effort' behind a creative work influences its perceived authority and value in a post-AI world.
