Newer large language models write better code because they have learned from broader training data, stronger feedback loops, improved reasoning methods, better tool use, and more focused evaluation. Older models could often complete simple snippets, explain common syntax, or produce boilerplate, but they struggled with larger tasks, hidden edge cases, dependency choices, and multi-step debugging. Modern models are not just better autocomplete systems; they are more capable programming assistants that can plan, revise, test ideas, and adapt to the style of a project.
