WebGPU LLM in Unity for NPC Interactions
An experiment with in-browser local inference using WebGPU has been integrated into a Unity game, where a large language model (LLM) serves as the NPCs' "brain" to drive decisions at interactive rates. Significant modifications were made to the WGSL kernels to reduce reliance on fp16 and support more operations for forward inference, with unexpected challenges in integrating with Unity due to Emscripten toolchain mismatches. While the WebGPU build offers a performance boost of 3x-10x over CPU depending on hardware, it remains about 10x less efficient than running directly on bare-metal hardware via CUDA. Optimizing WGSL kernels could help bridge this performance gap, and further exploration is needed to understand the limits of WebGPU performance. This matters because it highlights the potential and challenges of using WebGPU for efficient in-browser AI applications, which could revolutionize how interactive web experiences are developed.

Programming Languages for AI/ML
Python remains the dominant programming language for machine learning and AI due to its extensive libraries, ease of use, and versatility. However, for performance-critical tasks, languages like C++ and Rust are preferred for their optimization capabilities and safety features. Julia, Kotlin, Java, C#, Go, Swift, and Dart are also utilized for specific applications, such as platform-specific ML tasks or when native code performance is needed. Additionally, R and SQL are important for statistical analysis and data management, while CUDA is employed for GPU programming to enhance ML task performance. Understanding the strengths and applications of these languages is crucial for optimizing machine learning and AI projects.

Plotly’s Impressive Charts and Frustrating Learning Curve
Python remains the dominant language for machine learning due to its extensive libraries and versatility, but other languages are also important depending on the task. C++ and Rust are favored for performance-critical tasks, with Rust offering additional safety features. Julia, although not widely adopted, is noted for its performance, while Kotlin, Java, and C# are used for platform-specific applications. High-level languages like Go, Swift, and Dart are chosen for their ability to compile to native code, enhancing performance. R and SQL are crucial for statistical analysis and data management, while CUDA is essential for GPU programming. JavaScript is commonly used in full-stack projects involving machine learning, particularly for web interfaces. Understanding the strengths of these languages helps in selecting the right tool for specific machine learning applications.
