When using LLMs for modernization in a legacy codebase, model output must not be applied directly as patches; instead, the LLM should be positioned as an auxiliary tool for understanding the code.

UnverifiedLLMs are fundamentally autoregressive text generation models and are not designed for long-horizon task planning.79% similarUnverifiedThere is a mismatch between the LLM's objective function and the goals of legacy system maintenance: LLMs are trained to generate typical good code, whereas legacy systems require conservative changes to keep things as they are.78% similarUnverifiedReasoning models are not an entirely new architecture but rather a modified version of conventional LLMs—sharing the same architecture but possessing certain capabilities that older LLMs do not.75% similarUnverifiedNot calling LLMs for work that can be accomplished with deterministic scripts, and limiting LLM usage to tasks that genuinely require language understanding and generation, is a key engineering principle for production-grade AI systems74% similar
