6x faster migration from TensorFlow to JAX
AI coding agents are rapidly becoming ubiquitous across the software industry, fundamentally changing how developers write, test, and debug daily code. While these tools excel at localized, self-contained tasks, applying them to massive, systemic codebase migrations requires an entirely new approach.
Google is already addressing this challenge by incorporating AI into many migration workflows: x86 to ARM (enabling workloads on Google Axion processors); int32 to int64 identifiers (to avoid running out of ids); JUnit3 to JUnit4 (for testing); and Joda-Time to java.time (a modern time library). However, AI model migration represents a whole new level of complexity that requires even more advanced methods for AI-assisted migration.
Translating a production-grade machine learning model from one framework to another, for example, from TensorFlow (TF) to JAX, is not a simple syntax update. It is a long-horizon task that requires untangling thousands of lines of code, managing complex states across multiple files, and...
