Neither is inevitable. The risks depend on what is being built, the project’s scale, and whether teams can understand, test, secure, and maintain the resulting system.
What does “AI technical debt” mean?
Technical debt is the future work created when a software team takes a shortcut or makes a change that is harder to maintain than a better-understood alternative. The metaphor is useful because a shortcut can speed up delivery now while making later changes more expensive. It does not mean every quick fix is a mistake, or that every maintenance problem is debt.

With AI, the phrase can describe two different things. In the first, debt sits inside an AI-enabled system: the software includes one or more AI components, algorithms, or models, and the surrounding code, data, interfaces, dependencies, and operating processes all have to be maintained. In the second, debt may arise in ordinary software because a developer used generative AI to produce or modify code. These are connected, but one does not prove the other: an AI-enabled product can be well maintained, and an AI coding assistant can produce code for a non-AI product.
Where can debt build up inside an AI-enabled system?
For the first meaning, look beyond the model itself. A system’s quality depends on the pieces that connect the model to the rest of the software and on the work needed to keep those pieces understandable and secure.
#1 Best Overall
- Models and algorithms: Teams need to understand how a model fits into the software and what must be maintained when that component changes.
- Data: Data is part of the system’s lifecycle, not an isolated input. Unclear data handling or ownership can make later changes and evaluation harder.
- Interfaces and dependencies: A model interacts with software around it. Complicated or poorly understood connections can make changes riskier and increase the effort needed to maintain quality.
- Architecture and operations: The design of the whole system and the processes for operating it also carry maintenance obligations. A model that works in isolation does not establish that the system around it is easy to change or secure.
A 2024 Journal of Systems and Software study surveyed 53 AI practitioners about the prevalence, severity, impact, and management of technical debt in AI-enabled systems. Respondents identified effects on software quality, including understandability and security. The study also found limited support for managing this debt; reported initial approaches included manual review and ad-hoc refactoring. These are practitioner perceptions from 53 respondents, not a representative estimate of how common or severe the problem is across all deployed AI systems.
Is AI-generated code creating hidden technical debt?
It can, but the evidence does not support a blanket claim that using AI to write code always increases technical debt. Faster code generation may make it easier to add changes, but it does not automatically make those changes fit the system’s architecture, remain understandable, pass suitable tests, or meet security needs. If generated code is layered quickly onto an existing system without enough context or review, the short-term speed can leave extra work for the people who must change it later.
Edward Anderson, Geoffrey Parker, and Burcu Tan’s 2025 article in MIT Sloan Management Review, “The Hidden Costs of Coding With Generative AI,” examines this risk in the context of established, or “brownfield,” software systems. It draws on interviews with developers and leaders across several industries, trade-press review, and economic modeling. It is a strategic analysis, not a controlled experiment establishing that AI coding causes a particular amount of debt.

One recent empirical study offers a more specific, and more mixed, picture. Jonas Niemeyer and Michael Wessel’s 2026 ECIS paper analyzed 1,091 open-source Python repositories using a longitudinal interrupted time-series approach. Its findings differed by project scale and debt category:
| Repository group or debt type | Reported result after the intervention |
|---|---|
| Small and medium projects | Code debt accelerated at a statistically significant rate. |
| Large projects | Code debt remained stable. |
| Architectural debt | Decreased faster. |
| Design debt | Increased. |
The study concerns open-source Python repositories, not every company, programming language, or AI-assisted development workflow. Its results show why “AI raises technical debt” is too broad: the reported direction varied with project scale and type of debt.
What do the available figures say—and not say?
Software Improvement Group’s 2026 State of Software announcement reports that AI-generated code made up 1.9% of enterprise production code in its analysis. The announcement describes the underlying benchmark as spanning more than 30,000 systems and more than 400 billion lines of code. These are publisher-reported benchmark details, not a universal census of enterprise software.
The same announcement says the group’s testing found roughly twice as many security-risk violations in AI-generated code as in human-written code. It also reports that 86% of code in its analysis fell below its recommended maintainability rating, and that 72% of production AI systems scored below its recommended build-quality rating. Those figures describe Software Improvement Group’s benchmark and recommendations; they should not be treated as independently established rates for all software.

Luc Brandts, Software Improvement Group’s CEO, said in the company’s June 9, 2026 announcement: “When generation outruns governance, technical debt accumulates faster, security exposure widens, and the systems a business depends on become harder to change,” This is a vendor executive’s characterization, not an independent finding. Across the sources cited here, there is no directly comparable, cross-industry causal estimate for how much AI coding raises technical debt overall. The repository study, practitioner survey, and vendor benchmark measure different things and should not be combined into one industry-wide figure.

The practical goal is not to ban generated code or to assume that human-written code is automatically safe. It is to keep delivery speed from replacing the work needed to understand and verify changes. The following controls are evidence-aligned recommendations, not a single proven recipe or a guarantee that debt will not accumulate.
- Track quality alongside speed. Monitor code quality and design or architecture indicators as well as delivery measures. A faster output rate alone cannot show whether the system is becoming harder to change.
- Review and test AI-assisted changes. Require a developer to understand the change in its surrounding system, review it, and run relevant tests. Treat generated output as a proposal, not as evidence that behavior is correct.
- Record context and rationale. Capture why a change was made and how it fits the system. This gives future maintainers more than a block of code whose intent they must reconstruct.
- Check dependencies and security. Include the change’s dependencies and security implications in review. Do not assume that code which appears to work is free of security risks.
- Match controls to scale and risk. A small project and a large, high-impact system may need different review and measurement practices. The 2026 repository findings are a reason to avoid one-size-fits-all conclusions.
- Assign lifecycle ownership. Make clear who is responsible for evaluating and maintaining the model or AI-enabled system, its software connections, and its operating processes after release.
What do NIST and GAO recommend teams account for?
NIST’s 2024 publication, SP 800-218A, augments version 1.1 of the Secure Software Development Framework with AI-specific practices and recommendations for model development throughout the software development life cycle. It is intended for model producers, producers of systems that use models, and acquirers. It provides a lifecycle-oriented framework for considering AI development; it is not a claim that following a checklist will eliminate technical debt.
A 2024 U.S. Government Accountability Office assessment describes practices used by commercial developers, including benchmark testing, multidisciplinary evaluation, and red teaming. It also notes limitations developers recognize: model outputs may be incorrect or biased, and systems may be vulnerable to prompt injection, jailbreaks, or data poisoning. For a team using AI in software or in its development process, the practical implication is to preserve human judgment, evaluate systems before release, and include relevant security risks in the development lifecycle.
