Software program Enchancment Group has revealed analysis linking AI coding instruments to larger technical debt, safety danger and working prices in enterprise software program. The findings are primarily based 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 carry the instruments into mainstream improvement.
One of many starkest examples is a case research by which 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 fulfill 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 strains, as a result of massive language fashions battle to know extra complicated software program structure. The research argues that AI doesn’t robotically enhance or weaken software program high quality, however as a substitute magnifies the requirements and controls already in place inside an engineering workforce.
Governance hole
That conclusion runs by a lot of the broader information within the report. In line with SIG, organisations with stronger governance round code high quality and structure can use AI to maneuver sooner, 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 extra 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 lowering code-level technical debt can save €870,000 in developer time per system annually. 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 lowered issue-resolution time by 30%.
Safety measures confirmed comparable 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 standard software program initiatives are additionally showing in newer AI deployments.
SIG stated its benchmark covers greater than 400 billion strains of code throughout greater than 30,000 techniques and greater than 300 applied sciences. The most recent findings had been drawn from techniques analysed over the previous yr and in contrast with impartial 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 improvement, however as a warning that sooner 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 those who study 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 sooner, safety publicity widens, and the techniques a enterprise is dependent upon change into tougher to take care of and evolve,” stated Luc Brandts, Chief Govt Officer at Software program Enchancment Group.
