Emergency patch, structural refactor, or full production rebuild — three tiers, three very different price tags. Why "how much to fix my app" has no single answer without an assessment, and what each tier actually involves.
Every AI fix has a measurable chance of breaking something that was working. Four documented mechanisms explain why — and none of them respond to more prompting.
You hired a freelancer to build your MVP. It's half-finished, undocumented, and the developer has gone quiet. Now you need to understand what rescue actually costs — and whether what you have is worth saving.
Veracode tested 150+ AI models and found 45% of generated code introduces OWASP Top 10 vulnerabilities. The failure rate for cross-site scripting defences is 86% — and it isn't improving with newer models. Here's what that looks like inside a real codebase, what you can check yourself in 30 minutes, and what the UK's National Cyber Security Centre is now saying about it.
Independent security firms have now audited thousands of AI-built apps. The same three architectural failures appear in virtually every codebase — and none of them are your fault.
AI has genuinely changed how fast you can build software – but the cost of getting it wrong in production hasn't moved an inch.
