{"slug": "quality-of-ai-code", "title": "Quality of AI Code", "summary": "A developer reports that switching from unstructured \"vibe coding\" to spec-driven development, in which an LLM generates code from a carefully maintained specification file, produced more reliable and cheaper results after early attempts yielded serious bugs. The developer says AI-assisted work improved both the quality and performance of the program and made the code easier to maintain by offloading some cognitive effort. The conclusion is that spec-driven AI-assisted coding, done with care by someone who knows what they are doing, can create or improve high-quality code.", "body_md": "Code that is **written by AI** (generated by LLMs) has had a **bad reputation**—it has bugs, is unreliable. And vibe-coded software has been thought to be even worse: it is felt to be unusable slop. But while AI coding does have drawbacks, it can be used to create **high-quality** software.\n\nWhen I first started trying to use AI, I ended up with some pretty **terrible bugs** from vibe coding. But I decided to move to **spec-driven development** where an LLM generates code from a carefully-maintained specification file. This ended up being more **reliable** (and also cheaper).\n\n• With AI, I improved the quality of my program, and also its performance.\n\n• I made the code easier to maintain, as I could \"offload\" some of the cognitive effort.\n\n• Spec-driven AI-assisted coding, done with care and thought by someone who knows what they are doing, can be used to create or improve high-quality code.", "url": "https://wpnews.pro/news/quality-of-ai-code", "canonical_source": "https://www.dotnetperls.com/2026_11_6_quality-ai-code", "published_at": "2026-11-06 07:00:00+00:00", "updated_at": "2026-11-06 14:49:37.780176+00:00", "lang": "en", "topics": ["ai-tools", "large-language-models", "generative-ai", "developer-tools"], "entities": [], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/quality-of-ai-code", "markdown": "https://wpnews.pro/news/quality-of-ai-code.md", "text": "https://wpnews.pro/news/quality-of-ai-code.txt", "jsonld": "https://wpnews.pro/news/quality-of-ai-code.jsonld"}}
