“This strategy has the potential to transform the way in which code is maintained in massive enterprises,” a bunch of authors from Google Core and Google Advertisements wrote in a brand new “expertise report” describing their strategy. “Not solely can it speed up the work of engineers, however make attainable efforts that have been beforehand infeasible because of the enormous funding wanted.”
In the end, Google’s aim was to determine alternatives for LLMs to offer further worth and help scale with out requiring difficult-to-maintain summary syntax timber (AST). These are extensively used to characterize the construction of a program or snippet of code, however they’re deterministic — that’s, outcomes are already recognized — and code migration use circumstances span way more complicated constructs which can be troublesome to characterize with ASTs, the authors defined.
“Attaining success in LLM-based code migration isn’t easy,” the authors famous. “The usage of LLMs alone by means of easy prompting isn’t enough for something however the easiest of migrations. As a substitute, as we discovered by means of our journeys, and as described within the case research on this paper, a mixture of AST-based strategies, heuristics, and LLMs are wanted to attain success. Furthermore, rolling out the modifications in a protected approach to keep away from pricey regressions can be vital.”
