Software program Enchancment Group has revealed analysis linking AI coding instruments to increased technical debt, safety danger and working prices in enterprise software program. The findings are based mostly on evaluation of 30,000 enterprise techniques.
The group’s State of Software program 2026 research examines how AI-assisted coding and autonomous software program brokers have an effect on code high quality, maintainability and spending as companies convey the instruments into mainstream growth.
One of many starkest examples is a case research wherein autonomous AI brokers constructed a software program system in per week, however generated between €10 million and €15 million in AI token charges and produced code described as practically unmaintainable.
The report says builders are more and more producing extra code to satisfy AI-driven productiveness measures, solely to spend extra time and extra tokens correcting and refining the output later. It additionally discovered that AI-generated code confirmed roughly twice as many security-risk violations as human-written code, whereas greater than half contained vulnerabilities.
SIG stated the productiveness features from AI coding instruments can disappear as soon as a codebase reaches 100,000 traces, as a result of massive language fashions wrestle to know extra advanced software program structure. The research argues that AI doesn’t robotically enhance or weaken software program high quality, however as an alternative magnifies the requirements and controls already in place inside an engineering staff.
Governance hole
That conclusion runs via a lot of the broader knowledge within the report. In line with SIG, organisations with stronger governance round code high quality and structure can use AI to maneuver quicker, whereas these with weaker controls danger accumulating technical debt and safety issues extra rapidly.
The research says AI-generated code now accounts for 1.9% of enterprise manufacturing code throughout the benchmark reviewed. For groups utilizing non-agentic AI coding instruments, token spending for a bunch of fifty builders now averages practically the price of one further developer, whereas agentic coding duties can devour as much as 1,000 occasions extra tokens than normal code chat or reasoning duties.
SIG additionally estimates that decreasing code-level technical debt can save €870,000 in developer time per system every year. It discovered that 86% of code in its benchmark falls beneath its really helpful maintainability score.
Structure scores additionally remained weak. Half of the code assessed scored beneath SIG’s really helpful structure score, whereas stronger structure diminished issue-resolution time by 30%.
Safety measures confirmed related weaknesses throughout the benchmark. The report discovered that 71% of code had a low diploma of safety controls, and that techniques with decrease code-level technical debt confirmed as much as 72% stronger safety compliance.
AI techniques
The analysis additionally examined the software program high quality of AI techniques already in manufacturing. It discovered that 72% of these techniques scored beneath SIG’s really helpful build-quality score, suggesting that the governance points affecting typical software program tasks are additionally showing in newer AI deployments.
SIG stated its benchmark covers greater than 400 billion traces of code throughout greater than 30,000 techniques and greater than 300 applied sciences. The most recent findings have been drawn from techniques analysed over the previous yr and in contrast with unbiased analysis.
Luc Brandts, Chief Govt Officer at Software program Enchancment Group, stated the outcomes shouldn’t be learn as a rejection of AI in software program growth, however as a warning that quicker code technology with out stronger engineering oversight can create substantial downstream prices.
“Nothing on this report is an argument towards AI. The productiveness features are actual, and organisations that fail to embrace it danger falling behind people who be taught to make use of it successfully. However you can not handle what you don’t measure, and you can not maintain pace on a basis you don’t perceive. When code technology outruns governance, technical debt accumulates quicker, safety publicity widens, and the techniques a enterprise relies on develop into tougher to take care of and evolve,” stated Luc Brandts, Chief Govt Officer at Software program Enchancment Group.
