Learn Vector Databases Before Building Your Next AI Project
At a high level, a vector database is a special type of database designed to store and search something called embeddings. And before that word scares you away, don’t worry — embeddings are much simpler than they sound.

How to Build an LLM from Scratch with PyTorch: A TinyGPT Tutorial
Introduction: You Use LLMs Every Day — But Do You Know What's Inside? You call openai.ChatCompletion.create(...) and a response appears. You paste code into Copilot and a completion materialises. It feels like magic, and for most developers it stays magic indefinitely — because none of the hosted APIs ever ask you to care about tokens, attention masks, or training loss. That gap between using a language model and understanding one is quietly becoming a career bottleneck. Inte

How to Build a CNN From Scratch in Python: Conv2D, TinyResNet, CIFAR-10, and Grad-CAM
1. Introduction: The "Black Box" Problem in Computer Vision You open a PyTorch tutorial. Four lines of code, a pretrained ResNet, and — boom — 94 % CIFAR-10 accuracy. You follow along, copy the snippet, get the number. Then someone asks: "What does a convolution actually do?" and you realise you have no idea. This is the most common frustration in beginner computer vision. Frameworks are deliberately designed to hide implementation details, and that abstraction is great for s

How to Build Speech Recognition From Scratch with Python, PyTorch, MFCCs, and OpenAI TTS
Introduction You have watched enough "speech recognition in 5 minutes" videos. Every tutorial starts the same way: pip install openai-whisper, load a model, call transcribe(), done. That is not learning speech recognition — it is calling someone else's black box. When the transcription is wrong, when latency is too high, or when you need to run entirely offline on a Raspberry Pi, you have no idea where to start debugging because you never understood what actually happens betw

How to Build DeepSeek-R1 from Scratch - GRPO Reinforcement Learning Explained
Introduction: The Techniques Behind 2026's Most Impressive AI Systems Are Still a Black Box If you have spent the last several months watching reasoning models outperform every benchmark in sight, you have probably asked the same question most ML engineers ask: how, exactly, does this work? The honest answer — after reading every public paper, blog post, and GitHub repo — is that most explanations stop precisely where the interesting part begins. You get the high-level pitch

How to Build a Chain-of-Thought Reasoning Model from Scratch (PyTorch + GSM8K)
1. The Problem: Your LLM Gives Confident, Fluent, Wrong Answers You feed a language model a math word problem. It returns an answer instantly — beautifully formatted, grammatically perfect, completely wrong. No working. No intermediate steps. Just a number, stated with the quiet confidence of a student who copied from the back of the book. This is not a corner case. It is the default behaviour of any model trained purely on next-token prediction. The model has learned to patt

How to Build a Vernacular Loan Origination System with Sarvam-105B and Sarvam Vision
Introduction Picture this: a small dairy farmer in Nagpur uploads his Aadhaar card — handwritten back-side details in Devanagari — along with six months of bank statements packed with narrations like UPI/PayTM/SAL CR JAN, EMI ICICI HOM, and ATM WDL KOTAK. Your backend passes it to a global OCR vendor and a frontier LLM. The OCR misreads half the Devanagari glyphs. The LLM hallucinates a salary figure. The application gets flagged for manual review.

How to Build a Multilingual Insurance Claims Triage System with Sarvam Vision and Sarvam-105B
Introduction Every day, a claims processor at a mid-sized Indian health insurer opens a WhatsApp message and finds a photograph of a doctor's prescription — written in looping Devanagari on a torn notepad, half-smudged, with Latin drug abbreviations mixed in. She types what she can read into a legacy system, guesses at the rest, and moves to the next claim. Multiply that across millions of motor and health claims annually, in Hindi, Marathi, Tamil, Bengali, Gujarati, and seve

Your first instinct is to send it all to Google Translate. Three days later, QA flags that "BoAt" is now appearing as "नाव" (the Hindi word for boat), "500 g" has become "500 ग्राम" on some items and "500gms" on others, half the ₹ prices have dropped their currency symbol,

Every day, hundreds of agents call borrowers in Hinglish, Bhojpuri-Hindi, Tanglish, and Marathinglish. Every one of those calls is recorded — and stored. Yet the QA team manually reviews fewer than two percent of them. The rest disappear into a storage bucket, reviewed only when a customer complaint or RBI audit forces someone to dig in.
