Stop Using AI Only to Build—Start Using It to Break Your Systems

Swapneswar Sundar Ray — Mon, 04 May 2026 00:45:05 +0000

Most of us have gotten comfortable using AI to speed things up—write code, generate tests, clean up documentation. It’s become a productivity tool. But there’s another way to use AI that feels less obvious and, in many cases, more valuable: using it to challenge your system instead of helping it.

If you’ve worked on real production systems, you already know this—things don’t usually break in obvious ways. They break in small, annoying, hard-to-reproduce ways. A value comes in with a slightly different format, a field has an extra space, casing changes, or something gets reordered. Nothing looks “wrong,” but suddenly the system behaves differently. These are the kinds of issues that slip through testing and show up later when it’s much harder to debug.

The reason this happens is simple. Most testing reflects how engineers think, not how real inputs behave. We test the expected cases, maybe a few edge cases, and call it done. Even automated tools often generate inputs that are either too clean or completely random. Neither really captures how data looks in the wild.

This is where AI starts to become useful in a different way. Instead of asking it to create solutions, you ask it to create variations. Give it one valid input, and it can produce multiple versions of that same input that still mean the same thing but look slightly different. That’s exactly the kind of variation that exposes weaknesses in systems.

Think about a basic API that takes an amount and a currency. You test it with something like “1000.00 USD,” and everything works. But what happens when the input becomes “1000”, or “1,000.00”, or has extra spaces, or uses lowercase for the currency? These aren’t unusual cases—they happen all the time. Yet many systems treat them differently, sometimes rejecting them, sometimes misinterpreting them, and sometimes behaving inconsistently.

Instead of manually trying to think of all these possibilities, you can let AI do that work. Treat it like a mutation engine. Start with one valid input and ask for realistic variations that don’t change the meaning. Then run all of them through your system and observe what happens. You’re no longer just testing whether the system works—you’re testing how stable it is when things are slightly off.

This changes what you pay attention to. Instead of only asking, “Did this pass or fail?” you start asking, “Did the system behave the same way across all these inputs?” Because if two inputs are effectively the same but produce different outcomes, that’s a deeper issue. It’s not just a bug—it’s inconsistency in how your system interprets the world.

The nice part is that you don’t need a complicated setup to try this. You can start small. Generate a handful of variations using AI, run them through your existing flow, and compare the results. Even this simple exercise can reveal things that traditional testing misses.

This approach becomes especially useful in systems where input variability is common. Financial applications are a good example, where formatting differences can affect validations. OCR pipelines often deal with slightly inconsistent outputs for the same text. And modern AI-driven systems themselves can behave differently based on small changes in input phrasing. In all these cases, stability matters just as much as correctness.

One thing to watch out for is overusing AI without direction. If you generate too many random variations, you end up with noise instead of insight. The goal isn’t to overwhelm the system—it’s to explore meaningful differences. Another common mistake is focusing only on correctness and ignoring consistency. Both matter, but consistency is often what reveals deeper issues.

A more balanced way to think about this is to combine approaches. Let your code handle strict validation and rules. Use AI to explore the gray areas—the inputs that are technically valid but slightly different. Together, they give you a much better understanding of how your system behaves.

If you look back at most production issues, they rarely come from completely invalid data. They come from those edge cases that no one thought to test. Usually, a small percentage of inputs ends up causing a large share of problems. Adversarial testing is simply a way to find those cases earlier, when it’s easier to fix them.

In the end, AI isn’t just a tool for building faster. It’s also a way to question whether what you’ve built actually holds up under real conditions. When you start using it to push your system instead of just supporting it, you begin to uncover things you didn’t even realize were there.

And that shift—using AI not just as a helper but as something that challenges your system—is where the real learning starts.

I tried using AI to build an exam system. It worked… until it didn’t.

Swapneswar Sundar Ray — Sat, 02 May 2026 17:05:20 +0000

I didn’t start with the idea of building an exam platform. This actually came from a different problem. We were using AI to generate structured data for APIs, and everything looked fine at first. The responses were correct, nothing obviously wrong. But then things started breaking in production in very strange ways. One example was a value like 120.5 instead of 120.50. Same number from a human point of view, but the downstream system rejected it because it expected an exact format. These were small issues, but they took a lot of time to debug and they kept happening.

That got me thinking. If AI behaves like this with structured data, what happens when we use it to generate exam questions or evaluate answers? In demos it looks impressive. It can generate questions instantly, even evaluate answers. But in real usage, consistency becomes a problem. Difficulty levels vary randomly, answers are not always structured the same way, and evaluation can feel subjective. That’s not something you can rely on for students or schools.

At first, I tried fixing it the usual way—by improving prompts. Making them longer, adding more rules, being very specific. It helped a little, but it didn’t solve the core issue. You still get edge cases where the output is slightly off. That’s when I realized the problem is not the prompt. The problem is trusting AI output directly without control.

So instead of trying to “fix AI,” I built a small system around it. It’s a simple Java-based application that runs as a JAR. Students can enter their details, choose subject and topic, and the system generates questions, runs a timer, collects answers, and produces a report. Nothing very new there. The important part is what happens in between.

Home Page (Landing + Features)

This is the main entry point of the system. It shows the overall idea clearly — an AI-powered exam platform where users can generate questions, register, and select topics.

What stands out here is that the system is not just a basic form-based app. It is positioned as a complete examination framework, with features like AI question generation, evaluation, timer, and reporting already integrated.

The feature section below highlights the core capabilities in a structured way. It shows that the platform is designed to handle the full exam lifecycle, not just question generation. That makes it more like a system solution rather than a small tool.

Student Registration

This screen captures detailed student information — not just name and email, but also age, country, experience, interests, and education level.

This is important because the system is trying to personalize question generation based on user context. It shows that the design is thinking beyond generic questions and moving toward adaptive exam generation.

The structure is simple, but the idea behind it is strong — collecting enough context so AI can generate more relevant and meaningful questions.

Topic Selection

This screen shows predefined exam topics like Java, Spring, System Design, etc., with clear details:

difficulty level
number of questions
time duration

This is where the system becomes more structured. Instead of random question generation, it introduces controlled exam configuration.

It also shows that the system is trying to balance:

flexibility (multiple topics)
control (fixed duration, levels)

This reduces randomness and makes the exam predictable.

Exam Start Screen

This screen shows instructions before the exam starts. It includes rules like:

time limits
no refresh
answers cannot be changed

Mathematics – Easy

This screen shows basic math questions like addition and multiplication. At first glance, it looks like a normal quiz, but behind the scenes the questions are generated using AI based on the selected subject (Mathematics) and difficulty (Easy).

When the user selects the topic, the system sends a prompt to the AI like:

“Generate easy-level math questions with multiple choice answers in a fixed format.”

AI returns a response, but the system does not directly display it. Instead, it validates the structure:

ensures each question has exactly 4 options
checks formatting consistency
extracts the correct answer

For math questions specifically, the system can also verify correctness deterministically. For example:

15 + 27 is recalculated by the system
the correct answer is confirmed before being stored

Science – Medium

In this screen, the questions are conceptual, like chemical symbols or physics facts.

Here, the system relies more on AI knowledge, but still enforces:

structured question format
single correct answer
valid option set

Since these are not numeric, the system cannot “calculate” answers the same way as math. Instead, it:

cross-checks answer format
ensures only one correct answer is marked
optionally re-prompts AI for clarification if response is ambiguous

Programming – Hard

This screen shows advanced questions like time complexity and data structures.

Here, the system uses AI to generate:

domain-specific questions
appropriate difficulty
relevant answer choices

To improve reliability, the system:

enforces known patterns (e.g., Big-O notation format)
validates option consistency
ensures only one correct answer is selected

For some questions, the system can also apply rule-based validation, like:

valid complexity values (O(n), O(log n), etc.)
known correct answers for standard problems

This is a small but important part. It shows that the system is thinking about real-world exam conditions, not just generating questions.

The “Start Exam Now” action clearly separates setup from execution, which is good design for flow control.

Every AI response goes through a validation layer before it is used. That means checking structure, fixing formatting issues, ensuring required fields exist, and making sure the output is consistent. So instead of just taking what AI gives, the system adjusts it into something predictable. In simple terms, AI suggests, but the system decides.

The system is designed to keep the experience simple and clear for students. Every question follows the same format, with the same number of options and a consistent layout, so students don’t get confused or distracted by changing structures.

When a student clicks on “Show Answer”, it’s not just revealing whatever the AI generated. The answer has already been carefully processed by the system. It is first extracted from the AI response, then validated to make sure it is correct and properly formatted. For numerical questions, the system can even recheck the calculation before showing the answer.

This way, students can trust that the answer they see is accurate, consistent, and helpful for learning—not just a random AI output.

This small change made a big difference. The system became much more stable. The outputs were consistent. The same input would lead to similar structure every time. It stopped feeling like a demo and started behaving more like something usable.

I also kept the system intentionally simple. No heavy UI, no complex setup. Just a Java JAR with an in-memory database. You can run it locally and try it out. The goal was not to build a full product, but to test this idea of combining AI with strict validation.

I’m sharing this because I keep seeing the same pattern everywhere. AI-first systems look great initially, but small inconsistencies show up later and cause real problems. Not big failures, just small ones that are hard to trace. Adding a control layer seems boring, but it makes the system reliable.

If you’ve worked on something similar—AI-generated data, exam systems, or validation layers—I’d be interested to hear how you handled it. Did you keep improving prompts, or did you add some kind of control mechanism?

I’ve put the project here:
GitHub: https://github.com/swapneswarsundarray/ai-assisted-exam
Feeback: https://swapneswarsundarray.github.io/ai-assisted-exam/feedback.html

Still early, still evolving. If this sounds interesting, feel free to try it out or contribute. Would be good to build this with more real-world input.

In the end, I don’t think AI replaces systems. It just becomes one part of it. The rest is still structure, validation, and control. That’s where things actually start working properly.

Will tools like ChatGPT replace developers?

Swapneswar Sundar Ray — Thu, 30 Apr 2026 20:11:14 +0000

We’ve been hearing this question a lot
“Will ChatGPT replace developers?”

After working with AI in real projects, my answer is: no… but it will change how we work.

At first glance, it’s easy to feel like it might. ChatGPT can write code, explain concepts, fix bugs, and even generate full functions in seconds. For small tasks, it’s incredibly useful. It saves time, reduces effort, and helps you move faster.

But once you step into real systems, things look very different.

In real-world environments, nothing is clean. Requirements change halfway through. Systems depend on other systems that don’t always behave the way you expect. Inputs are messy. Failures happen at the worst possible time. And sometimes, the problem itself isn’t even clearly defined.

This is where developer skill actually matters.

Writing code is just one part of the job. A good developer spends more time:

understanding how systems behave
making decisions when things are unclear
designing for failure, not just success
balancing trade-offs between speed, cost, and reliability

These are things AI doesn’t really “own.” It can assist, but it doesn’t take responsibility.

I’ve personally seen cases where AI-generated code looked perfect at first, but didn’t hold up when integrated into a larger system. It missed edge cases, didn’t consider dependencies, or made assumptions that weren’t true in production. Fixing those issues still required human judgment and experience.

That’s when it becomes clear—AI is powerful, but it’s not the system. It’s just a part of it.

What’s changing is not the need for developers, but the definition of a good developer.

Earlier, writing code quickly was a big advantage. Now, it’s becoming more about:

asking the right questions
guiding AI effectively
validating outputs
building systems that are stable and predictable

In a way, developers are moving from “code writers” to “system thinkers.”

The developers who will struggle are not the ones being replaced by AI—but the ones who refuse to adapt to it.

And the ones who will stand out are those who learn how to use AI as a tool, without depending on it blindly.

So no, ChatGPT won’t replace developers.

But developers who learn how to work with tools like ChatGPT will definitely have an edge.

And maybe that’s the real shift happening right now.

The Hidden Cost of AI Programming (and How to Use It Mindfully)

Swapneswar Sundar Ray — Mon, 27 Apr 2026 20:59:35 +0000

“AI didn’t break your code. You just trusted it too much.”

AI tools like GitHub Copilot and ChatGPT are changing how we write software. You type a comment… and suddenly a full function appears.

Feels magical.
Feels fast.
Feels productive.

But here’s the uncomfortable truth:
AI can quietly make you a worse engineer if you’re not careful.

This isn’t anti-AI. I use it every day.
This is about using AI like a senior engineer, not like autocomplete on steroids.

The Bad Side of AI Programming
1. You Stop Thinking Deeply

AI gives you answers, not understanding.

def calculate_discount(price, discount):
return price - (price * discount)

Looks correct…

But:

What if discount = 20 instead of 0.20?
What if price is negative?
What if discount > 1?

AI doesn’t validate business logic — it just generates code.

2. Context Blindness
AI doesn’t know your:

system architecture
scale requirements
domain rules
app.get('/users', async (req, res) => {
const users = await db.getAllUsers();
res.json(users);
});

Looks clean.

But in production:

No pagination
No rate limiting
No authentication
No caching

You just created a production risk.

3. Confidently Wrong Code

AI sounds correct — even when it’s wrong.

List list = Arrays.asList("a", "b", "c");
list.add("d"); // Runtime error

Arrays.asList() returns a fixed-size list.

AI misses subtle language rules.

*4. Technical Debt Explosion
*
AI optimizes for:

“Make it work”

Not:

“Make it scalable and maintainable”

function processOrder(order) {
if(order.type === 'A') { ... }
else if(order.type === 'B') { ... }
else if(order.type === 'C') { ... }
}

No design pattern
No extensibility
Hard to maintain
1. Debugging Skills Get Weaker

If AI writes everything, what happens when things break?

You’re stuck debugging code you don’t fully understand.

The Mindful Way to Use AI

1. AI is powerful — if used correctly.

Use AI for Drafts, Not Decisions

Bad:

“AI wrote it, ship it”

Good:

“AI wrote it, now I validate it”

2. Always Add Constraints

Instead of:

“write a user API”

Say:

“write a paginated, rate-limited, authenticated API with error handling”

Example (Better API)
`app.get('/users', async (req, res) => {
const { page = 1, limit = 10 } = req.query;

if (limit > 100) {
return res.status(400).json({ error: "Limit too high" });
}

const users = await db.getUsersPaginated(page, limit);

res.json({
page,
limit,
data: users
});
});
`

3. Treat AI Like a Junior Developer

Always:

review the code
question assumptions
test edge cases

4. Ask AI “Why”, Not Just “What”

Instead of:

“give me code”

Ask:

“explain trade-offs, edge cases, and risks”

5. Use AI for Repetitive Work

Best use cases:

boilerplate code
test cases
documentation
refactoring suggestions

Not for critical architecture decisions.

AI is not the problem.

Blind trust is.

The best engineers don’t replace thinking with AI.
They amplify thinking with AI.

LangChain and LangGraph: Building Reliable Agentic AI Workflows

LangChain and LangGraph: Building Reliable Agentic AI Workflows

Modern AI applications are no longer simple chatbot wrappers around an LLM.

Real enterprise AI systems need to:

understand user intent
retrieve relevant context
call tools and APIs
maintain state
follow business rules
validate outputs
retry failed steps
escalate risky decisions
produce auditable results

This is where LangChain and LangGraph are useful.

LangChain provides building blocks for connecting LLMs with tools, prompts, retrievers, vector databases, APIs, and external systems.

LangGraph provides a graph-based orchestration layer for building stateful, multi-step, controllable AI workflows.

In simple terms:

LangChain connects the AI to capabilities.

LangGraph controls how those capabilities are used.

1. What Is LangChain?

LangChain is a framework for building applications powered by large language models.

It helps developers connect LLMs with external components such as:

prompt templates
tools
APIs
retrievers
vector stores
document loaders
output parsers
memory
agents

A typical LangChain-based application may look like this:


text
User Query
   |
   v
Prompt Template
   |
   v
Retriever / Tool
   |
   v
LLM

Final Thought

AI tools do not create impact.

Systems do.

The teams succeeding with AI are not using better tools.

They are using tools more effectively.

Banks and AI

Swapneswar Sundar Ray — Sun, 26 Apr 2026 00:43:12 +0000

Banks invested billions in AI.

Fraud detection.

Credit scoring.

Customer experience.

Risk modeling.

The promise was massive.

But here’s the uncomfortable truth:

Most AI projects never make it to production.

Not because the models don’t work.

But because everything around them fails.

From my experience building AI systems in banking, the pattern is always the same.

The Real Problem

AI doesn’t fail at the model level.

It fails at the system level.

Let’s break it down.

Where AI Projects Break

1. The “Pilot Trap”

Every bank has this story:

Build a model
It works in a demo
Leadership is impressed

And then… silence.

Why?

No production infrastructure
No ownership after POC
No integration roadmap

Result:

Great demos. Zero impact.

2. Legacy Systems Kill Momentum

AI needs:

Clean data
Real-time access
APIs

Banks often have:

Data silos
Batch pipelines
Fragile integrations

AI becomes a side layer, not core infrastructure.

3. Data Reality Check

Everyone assumes:

“We have years of data—we’re ready.”

Reality:

Missing fields
Inconsistent formats
Historical bias

Garbage in → Garbage out

4. Compliance Slows Everything

Banking isn’t a startup.

Every model must be:

Explainable
Auditable
Fair

What happens:

Models get rejected late
Legal blocks rollout
Risk teams force simplification

Speed → Gone

Momentum → Gone

5. Business vs Tech Misalignment

AI teams build models.

Business teams expect ROI.

But:

No shared KPIs
No domain alignment
No clear success metric

Misalignment = failure.

6. No MLOps = No Product

Most teams stop at:

“Model trained”

But production needs:

Monitoring
Drift detection
Retraining
Versioning

Without MLOps, models decay fast.

The Reality (Simple View)

Typical AI Project Flow in Banks:

Idea → Pilot → Demo → Approval → Stuck → Dead

What Actually Works:

Idea → Data → Architecture → Integration → Deployment → Monitoring → Impact

What Actually Worked (In Production)

Here’s what changed everything for us:

1. Start With Business, Not Models

Instead of:

“Let’s build AI”

We asked:

“What business problem matters?”

Examples:

Reduce fraud loss by X%
Improve loan approval speed

AI became outcome-driven, not experiment-driven.

2. Fix Data Before Models

We invested in:

Clean pipelines
Standard schemas
Strong governance

Data became usable and reliable.

3. Build for Production From Day One

No throwaway pilots.

Every model had:

API endpoints
Integration plan
Deployment path

If it can’t scale, don’t build it.

4. Bring Compliance Early

Instead of late approvals:

Risk teams involved from day one
Explainability built-in
Documentation automated

Compliance became a partner, not a blocker.

5. Build Cross-Functional Teams

We combined:

Engineers
Data scientists
Domain experts
Risk & legal

Decisions got faster, clearer, and aligned.

6. Invest in MLOps

We implemented:

CI/CD for models
Monitoring dashboards
Automated retraining

Models stayed reliable in production.

The Outcome

Faster deployments
Lower failure rates
Higher reliability
Real business impact

Most importantly:

AI became a capability — not an experiment.

Final Thought

AI in banking isn’t failing because it’s too complex.

It’s failing because:

Organizations treat AI like a project.

Not like infrastructure.

Until that changes…

Failure rates won’t.

Stop Building One Giant Prompt: A Better Way to Design LLM Systems

Swapneswar Sundar Ray — Sat, 25 Apr 2026 18:56:55 +0000

## Most early LLM apps start the same way:

“Let’s just put everything into one prompt and let the model handle it.”

So we write a prompt that tries to:

validate input
transform data
generate output
summarize
add reasoning
handle edge cases

…and somehow do it all in one call.

It works—until it doesn’t.

The Problem with “God Prompts”

As the prompt grows:

Instructions start conflicting
Context becomes noisy
Accuracy drops
Outputs become inconsistent

You end up with:

a very expensive confusion engine

I’ve hit this multiple times while building AI systems.

What’s Actually Happening

You’re increasing what I call LLM cognitive load.

The more responsibilities you push into a single call:

the harder it is for the model to prioritize
the easier it is to miss instructions
the more likely it is to hallucinate

Even with better models, this pattern doesn’t go away.

A Better Approach: Think Like a System Designer

Instead of one big prompt, break the problem into smaller, focused steps.

Validate + transform + summarize + generate + explain everything

Do this:

Validation step (code)
Extraction step (LLM)
Transformation step (code or LLM)
Generation step (LLM)
Formatting step (code)

Use the Right Tool for the Right Job

Let code handle:

validation
parsing
routing
rules
state

Let LLM handle:

reasoning
interpretation
summarization
ambiguity

Treat LLM Calls Like Microservices

This mindset shift helped me a lot:

Each LLM call should have a single responsibility

Small input
Clear task
Predictable output

Then orchestrate them together.

Real-World Example

While working on API automation systems, we initially tried:

one prompt to validate specs + generate APIs + create mock data

It became unstable very quickly.

Splitting it into:

validation module
generation module
mock data module

made the system far more reliable.

LLMs are powerful—but they’re not a replacement for system design.

“Just add AI” is not an architecture pattern.

Design your system first.
Then use AI where it actually adds value.
