According to Jeff Dean (@JeffDean), he and Sanjay Ghemawat have published an external version of their internal Performance Hints document, which summarizes years of expertise in performance tuning for code used in AI systems and large-scale computing. The document, available at abseil.io/fast/hints.html, outlines concrete principles such as optimizing memory access patterns, minimizing unnecessary computations, and leveraging hardware-specific optimizations—critical for improving inference and training speeds in AI models. These guidelines help AI engineers and businesses unlock greater efficiency and cost savings in deploying large-scale AI applications, directly impacting operational performance and business value (source: Jeff Dean on Twitter).
