Applied with AI - Sanjay Kumar

I’m an Enterprise Cloud Architect and an AI Engineer. Through this channel, I aim to give back to my Tamil community by sharing the knowledge I've gained over 16 years of experience in the tech industry.

Are you tired of AI theory and want to build real AI applications instead? You're in the right place.

On this channel, we don’t just talk about AI, we build with it.
Each video is a step-by-step guide where we create real-world AI apps using:

Python and Fast API

LLMs (like GPT & Gemini)

Function Calling & Tool Usage

LangChain, LangGraph, and RAG

Cloud + AI Deployment (AWS, GCP)

Voice Interfaces & Multi-Agent Systems

Everything is explained in Tamil, so you can learn deeply and confidently in your own language.

Where does an LLM Gateway typically sit in a modern AI application's architecture?

What if giving an AI agent more context actually makes it less reliable?

In my upcoming "members-only" video, I’ll show a practical demo of:

- How an LLM makes bad judgements as more context gets added (We call it "Context Rot")
- Why this happens even when the rquired information is still present in the context
- How a Context Engineering technique can make the agent more reliable

This is a hands-on demo of Context Rot, where we’ll see the problem in action and then use a key Context Engineering technique to improve the agent’s reliability.

Publishing tomorrow 13th September, exclusively for channel members.

Stay tuned! 🚀

⚠️ What if giving your AI model more context actually makes it less reliable?

We usually assume that the more information we give an AI agent, the better its answer should become.

But that is not always true.

Sometimes the most useful information gets buried under thousands of tokens of noise surrounding it.

This is called Context Rot, an important concept in Context Engineering.

I’ve just dropped a new members-only hands-on demo where you can experience this first-hand.

Don’t just learn Context Rot as a definition.

👉 Run the notebook and experience it yourself.

📢 **Update on English Audio**

I’ve seen many of your comments asking for **English audio on my older videos and Members-Only content**. Thank you for bringing this up, and I completely understand the request.

Over the last few days, the English audio versions of my recent videos have started reaching a much wider audience, and many new viewers have also joined the channel membership.

So here’s the update:

I’m currently working on adding **English audio to the Members-Only videos**, and you should start seeing those updates over the **next couple of days**.

I’m also looking at gradually adding English audio to some of the **older public videos**, especially the important and frequently watched ones.

Going forward, I’ll make sure new content is accessible in **both Tamil and English**.

Thank you for your patience, your feedback, and for supporting the channel. ❤️🙏

Exciting things are coming! 🚀

Currently English Audio is available on these videos:

Would you like me to build a series on Google Cloud’s AI Agent stack?

The series would cover "How to Build and Deploy AI Agents on Google Cloud".
