How to identify, tackle and avoid intent drift in AI

Artificial intelligence (AI) brings many benefits to CX, but it isn't without risk. We know to look out for hallucinations, we know to be vigilant of broken journeys, and we talk at length about preventing incorrect outputs and actions. 

What is less understood is intent drift. There are many ways AI can drift, but intent drift specifically concerns the accuracy of outputs. It can affect autonomous agents, LLMs, and machine learning models and without the right frameworks in place, is incredibly difficult to detect.

Writing for CX Network, Katja Forbes says intent drift is "the failure mode CX leaders haven't named yet and it doesn't show up on any dashboard you currently own". In fact, Forbes says it's possible for all the metrics on the dashboard to be green, while an unhappy customer goes undetected. 

Examples of intent drift include: 

Technically accurate but useless answers: A model programed to address customer questions still gives responses that are technically accurate, but do not address the customer's needs. 
Incomplete tasks: An AI agent may have been programed to complete multi-task workflows end-to-end, but over time it starts to miss steps, or consider the task complete when it is not. This could be particularly problematic when issuing refunds, or taking a customer through security checks. 

Model confusion: As outlined in Forbes' article, an experiment documented in 2025 saw a language model AI agent placed in  a simulated stock-trading environment and instructed to act as a portfolio manager for a fictional fund. The simple system prompt was to minimize the carbon emissions caused by the companies in the portfolio. The instruction wasn't updated, but the agent received too much information to draw on for its decisions and  gradually it began selecting higher-emission stocks. 

As the adage goes, prevention is better than cure – particularly when customers are involved. So, this article explains exactly what intent drift it and seven steps practitioners can take to tackle the root cause before CX is impacted.

What is intent drift? 

Intent drift is the erosion of accuracy in AI outputs. An AI or ML model may still do what it was instructed to do, but whether due to context overload, ambiguity in the original instruction, or a lack of monitoring, the output no longer matches the original instruction.

Instead, the model has shifted from the operational goals, target outputs, or reasoning chains it was programed to deliver. It isn't hallucinating, but it also isn't performing as programed. 
Hemang Upadhyay, senior manager of product management (AI) for LG Electronics North America, says: "Drift can come from the model, but it can also come from changing business rules, new products, updated policies, or stale knowledge."

Intent drift isn't the same as data drift. That occurs when the training data changes and the output does not. And it happens gradually. Upadhyay says to key to preventing it is to "treat AI as an operating capability, not a one-time deployment".

Sudarshan Reddy Gurampatti, senior machine learning engineer for JPMorgan Chase & Co., echoes this sentiment. "One thing I've learned is that deploying an AI system isn't the finish line. It's really the beginning," he says. "Business processes change, products change, customer behavior changes, and policies get updated. If the AI isn't monitored as those changes happen, the quality of its answers will gradually decline."

How can CX practitioners prevent intent drift? 

There are practical steps practitioners can take to identify and resolve drift. Here are seven that can be applied to any organization, explained without jargon: 

1. Establish a baseline for accuracy 

The first action, Upadhyay says, is to establish a baseline for accuracy by understanding what "good" looks like, so teams can detect degradation. This may include answer accuracy, retrieval quality, containment quality, escalation rate, customer satisfaction, first-contact resolution, human override rate, and the frequency of low-confidence responses. 

The baseline should then be applied as a representative test set against which the organization can continuously evaluate responses. "This test set should include common questions, complex cases, edge cases, policy-sensitive scenarios, and known failure patterns. If the same benchmark questions start producing weaker answers over time, that is an early warning sign," he says. 

2. Monitor everything frequently 

With a baseline established, the next step is a stringent monitoring and evaluation framework. 

Shalini Sivasamy, senior AI/ML engineer for New York Life, says this should be continuous rather than periodic. On one insurance AI project she worked on took the approach of tracing every step of the system's decision making so current performance could be compared against the baseline. It's an approach that can prevent drift reaching the customer. 

"A decline in performance against that benchmark was typically the earliest warning sign, often appearing well before end users noticed any change," she says. 

Gurampatti agrees, saying that looking through a sample of responses on a weekly basis can quickly reveal outdated information, inconsistent answers, or topics where the AI is beginning to struggle. "Small issues are much easier to fix before they affect a large number of users," he says.

3. Establish if drift really is the problem

There are many types of drift, and there are many things that can go wrong with an AI model. 

Gurampatti says many people immediately assume the model is drifting when the real problem is somewhere else. "Sometimes the knowledge base hasn't been updated. Sometimes a business policy has changed. Sometimes the AI is using an older document instead of the latest one. In many cases, what looks like model drift is actually a data or knowledge problem," he says. 

On this point, Sivasamy says it helps to evaluate two questions separately: Is the AI retrieving the right information, and is it presenting that information accurately? 

"A decline in answer quality often appears to be a model problem, when the underlying cause is retrieval drawing on outdated or lower quality information," she says. "Monitoring these dimensions independently makes it much faster to identify the true source of the issue."

4. Be prepared to find more than one problem

In some cases, there may be an issue with drift and the information retrieved. When monitoring, Upadhyay says: "The system may be retrieving outdated documents, missing newer content, ranking the wrong source, or failing to recognize context. 

"Monitoring should show which sources were retrieved, how confident the system was, and whether the final answer was grounded," he adds.

5. Ensure a human remains in the loop

AI should never be used to replace humans, and the risk of intent drift proves why. 
Sivasamy says human oversight is critical. On a multi-agent project she worked on, certain decisions required human review before the pipeline could proceed. "This created a continuous feedback channel, with reviewers identifying subtle quality issues well before they became visible in aggregate metrics," she explains. 

Humans must also remain vigilant of model performance. Gurampatti says one of the first things he tells teams is to pay attention to what users are saying. "When people start correcting AI responses, asking the same question repeatedly, or choosing not to use the AI's suggestions, it's usually a sign that something has changed. User feedback is often the earliest indicator that the system needs attention," he says. 

Upadhyay says the practice of capturing human feedback and escalation patterns should be a foundation of model maintenance. "If employees are correcting the AI more often, if customers are recontacting support, or if more cases are being escalated after AI interaction, quality may be drifting," he says. 

6. Establish variance thresholds 

Sivasamy says organizations should establish "explicit thresholds for acceptable variance and treat any breach as a trigger for immediate action". She adds: "Waiting until problems surface through customer complaints means the cost of correction has already grown considerably."

Gurampatti adds that simple performance tracking can also flag is answer quality is deteriorating, or other indicators are no longer green. These can include declines in customer satisfaction, or more conversations being escalated to human agents. "Those are good signals that something needs to be investigated," he says. "Monitoring these trends over time helps teams identify problems before users lose confidence in the system."

7. Introduce granular-level governance

As with all AI projects, governance is essential – and in more and more jurisdictions it is become a regulatory requirement. Governance that exists only at the macro-level is no longer enough. Individual systems and models must be governed, also.

Upadhyay says there should be governance around content changes, model updates, prompt changes, and system integrations. "The best monitoring approach combines technical evaluation with operational signals, so issues are detected before they become customer-facing failures," he says. 

Gurampatti advises that whenever updates are made, the changes should be validated  being made available to everyone. "Testing the updated AI with a representative set of business questions helps confirm that the answers have actually improved and that no new issues have been introduced," he explains. 

Preserving AI model integrity and customer trust

While intent drift is real and invisible, it isn't impossible to address. But to do so, practitioners must actively look for it by ensuring the correct systems are in place and taking accountability for the overall quality of how a model is performing. 

This doesn't require huge amounts of technical knowledge, but it does call for logical and critical thinking, a structured approach to decision making, a bird's eye view of the organization's knowledge management, and a deep understanding of how customers interact with the AI tools the organization has deployed. 

From a systems perspective, drift can be greatly minimized by programming for specific, unambiguous scenarios and not overwhelming the system with superfluous or conflicting knowledge and data. 

Gurampatti says: "For me, monitoring AI is less about watching the model and more about watching how the entire system is performing. The model, the knowledge, the data, and user feedback all need to be looked at together."

He adds: "Organizations that build this continuous feedback loop are usually able to identify problems early, improve the system over time, and keep AI reliable as the business continues to evolve."
