In my experience, AI made it quick to produce a first draft of code, but much slower to establish what that code actually did, why it failed, and how to fix it safely. The “10x” in this headline describes that personal imbalance—not a measured norm for developers. A better debugging workflow is to give an assistant evidence and context, ask it to investigate before proposing edits, and verify any small change against the project’s own checks.
Why a fast AI draft can create a slow debugging session
Generated code can look complete while still missing the intended behavior. The difficult work starts when its output is subtly wrong: a failing test, an unexpected result, or an error that appears only for a particular input. Then the developer has to understand the code, locate the cause, and judge whether a proposed fix solves the actual problem.

That friction shows up in Stack Overflow’s 2025 Developer Survey. Among 31,476 responses to its multiple-select question about AI-tool frustrations—64.2% of survey respondents—45% selected “Debugging AI-generated code is more time-consuming.” The most selected frustration, at 66%, was dealing with AI solutions that are “almost right, but not quite.” These are self-reported frustrations, not measurements of debugging hours or a typical writing-to-debugging ratio.

What changed: investigate before asking for a fix
A useful shift is to treat an AI assistant as a debugging partner that needs to reason from evidence, not as a patch generator. Start with the failure you can observe, supply the context needed to understand it, and ask for a diagnosis before inviting code changes.
#1 Best Overall
1. Pin down the failure
Lead with the exact error, unexpected output, or failing test. If you can reduce the problem to a minimal reproduction, do so; a smaller case makes it easier to separate the actual failure from unrelated code. State what you expected to happen and what happened instead.
2. Give the assistant enough context
Include the relevant surrounding code, intended behavior, representative inputs, environment details that could matter, and what you have already checked. Keep the context focused: a large code dump without a clear failure can make it harder to identify the relevant evidence.
3. Request a diagnosis, not an immediate edit
Ask what the code appears to do, which explanations could account for the observed failure, and what evidence supports each one. Ask what input or check would distinguish competing explanations. This helps expose an unsupported assumption before it becomes a patch.

Try inputs that differ from the failing case, especially boundary values and alternate valid inputs. Before accepting a change, ask why it addresses the specific failure and what other behavior it could affect. A plausible explanation is useful, but it is not proof that the code is correct.
5. Make a small change and verify it
Prefer a limited, reviewable edit over a broad rewrite. Inspect the diff, rerun the reproduction, and use the project’s existing tests or checks. Keep responsibility for deciding whether the behavior is correct: an assistant’s confident explanation does not replace verification.
Why assistants can jump to the wrong cause
Microsoft Research’s 2024 paper on ROBIN conversational debugging describes a familiar weakness of question-and-answer-style assistance: it may assume missing context or suggest a solution before locating the root cause. That is why asking for evidence and discriminating checks matters more than asking for the quickest plausible edit.
Rank #4
In a within-subject study with 16 industry professionals, Microsoft Research reported that its ROBIN system improved bug localization 2.5 times and bug resolution 3.5 times compared with AI-assisted debugging in Visual Studio before ROBIN. Those results apply to that research system and study—not to AI debugging generally, and not to the personal “10x” in this headline.

A practitioner example: use follow-up questions to test understanding
GitHub’s account of open-source developer Claudio Wunder’s workflow offers a concrete example. He keeps related code open in VS Code, asks Copilot what it thinks the code does and how it behaves with different user inputs, then follows up to find problems and possible solutions. Wunder describes the benefit this way: “I spend less time figuring things out through trial and error, and more time making sure my code is secure and performant,” he said. This is his account of a workflow, not a controlled demonstration that it works for every developer. GitHub Blog: “How developers spend the time they save thanks to AI coding tools”

How to read the apparently conflicting AI findings
Evidence about AI coding tools depends on who was studied, what task they did, and what was measured. A broad survey of reported frustration and a controlled study of code authoring or review answer different questions; neither establishes a universal effect on debugging time.
| Source and scope | What it found | What it does not establish |
|---|---|---|
| Stack Overflow, 2025 Developer Survey; self-reported, multiple-select frustration responses | 45% selected more time-consuming debugging; 66% selected near-correct AI answers as a frustration. | A measured time ratio, causal effect, or experience shared by all developers. |
| GitHub’s 2023 Copilot Chat study; 36 developers with five to ten years’ experience doing controlled API authoring, review, and feedback tasks | GitHub reports that 85% felt more confident in code quality and that reviews were completed 15% faster with Copilot Chat. | Whether debugging AI-generated code takes longer in ordinary development work. The study covered its defined authoring and review tasks. |
| Microsoft Research’s 2024 ROBIN study; 16 industry professionals in a within-subject evaluation | ROBIN improved localization and resolution results compared with the study’s earlier AI-assisted Visual Studio debugging condition. | A general productivity multiplier for other assistants, workflows, or developers. |
The Stack Overflow figures describe what respondents said they encountered; the GitHub and Microsoft results come from specific study setups. GitHub’s results do not disprove the survey’s reported frustration, just as the survey does not show that AI tools necessarily slow every developer down.

Keep the assistant’s role narrow and the verification yours
AI can help explain a code path, suggest causes, or identify useful test inputs, but those suggestions should be treated as hypotheses. The practical change is not to stop using generated code; it is to make debugging a deliberate loop: show the failure, investigate likely causes, test assumptions, make a small edit, and check the result.
