Socho aap LLM ko ek super-smart writer bolte ho. Uske andar jo main engine hota hai, use transformer kehte hain. Transformer ka kaam simple hai: words ko akela nahi, context ke saath samajhna. Jaise sentence: “Bank ke paas baitho.” Yahan bank river wala bhi ho sakta hai, ya money wala. Transformer har word ko baaki words se connect karke decide karta hai meaning kya hai. Isko imagine karo ek hand-drawn highlighter jaisa jo sentence me idhar-udhar jump karke important words par focus karta hai—isse bolte hain attention. “Paas” aur “baitho” dekhke “bank” ka correct hint mil jaata hai. Phir transformer har word ka updated, smarter version banata hai—context wala. Aise multiple rounds me, pura sentence clear ho jaata hai. Finally, isi clarity se LLM next word predict karta hai—aur natural text generate kar deta hai. Basically: transformer = attention + context, LLM ka core brain.
