Stack Overflow published the results of its 2026 Developer Survey on 6 October 2026. More than 30,000 people from 169 countries answered over seven weeks. Among respondents who use AI coding assistants or agents, 73% use them daily, and only 6.6% say they would trust AI with an important decision.
What the survey found
Stack Overflow reports that 66% of respondents use coding assistants or agents and 63% use general-purpose chatbots. Of those who use coding assistants or agents, 73% use them every day. A third of daily users of any AI tool spend four or more hours a day with them.
Claude Code (66%) and GitHub Copilot (59%) are the most used agents. Developers mostly apply them to generating code in familiar areas (67%) and debugging (61%). Only 20% use AI for deploying, operating or troubleshooting production systems.
Sentiment follows usage. Stack Overflow found that 62% of all respondents view AI at least somewhat positively, rising to 71% among daily users.
Where trust stops
Trust depends on being able to check the answer. Nearly half of respondents said they trust AI output when they can verify it easily, and 6.6% would trust it for an important decision. According to coverage of the report by IT Brief, 78.7% said source attribution matters when they judge AI-generated code or technical answers.
Context is the other limit. Developers named project goals and requirements (85%) and code and docs (73%) as the best sources of trusted context. Asked who they go to for specific answers, they named the people they work with first (72%).
What it means for engineering teams
Daily AI use is now the normal baseline, so the difference between engineers shows in how they check the output. The 20% figure for production work suggests most teams still keep review, deployment and incident handling in human hands. Cost has also reached the team level: Stack Overflow reports that developers weigh quality (75%) above cost (38%) when they pick models, while many organisations add usage limits and model routing.
Teams that want agents to produce reliable work need written requirements, documented code and reviewers who can tell a correct answer from a plausible one. That work usually falls on senior engineers, who the survey shows are also the people colleagues ask first.
What it means when you hire engineers
A CV that lists AI tools says little when 83% of developers already use them. The more useful question is how a candidate works with an agent on real code: what they hand over, what they review and how they catch a wrong answer. Our how we vet process tests this in two sixty-minute sessions in a real codebase, one with AI tools off and one with the candidate's own agents on.
