Short mein: ChatGPT ne tumhari company ki files kabhi nahi padhi. Company ka AI bot unse jawab de paata hai kyunki wo RAG use karta hai: pehle sahi page dhoondho, phir usse jawab likho.
Problem: AI sirf yaaddasht se bolta hai
Bina RAG ke, ChatGPT sirf us cheez se bolta hai jo usne training mein padhi. Tumhari office policy, tumhare notes, tumhara product manual: ye usne kabhi dekhe hi nahi. Isliye office ke sawal par wo guess karta hai (aur guess ka kya hota hai, wo Episode 3 mein dekha).
RAG = AI ka open-book exam
Episode 3 ki exam waali aadat yaad karo. RAG AI ko open-book exam deta hai: pehle sahi page dhoondho, phir jawab likho.
Poora naam: Retrieval Augmented Generation. Retrieval = dhoondhna, Generation = jawab banana. Ye naam 2020 mein Facebook AI ki ek research paper ne diya. (Idea isse purana hai, naam wahan se aaya.)
RAG ke 4 steps
- Chunk: apni files ko chhote tukdon mein kaato. Har tukda ek chunk.
- Embedding: har chunk ka meaning numbers mein badlo. Episode 1 mein words numbers bane the, yahan poore chunk ka meaning banta hai. Ye numbers ek vector database mein rakhe jaate hain.
- Retrieval: sawal aaya, to uske meaning se sabse milte-julte chunks dhoondho. Keyword se nahi, meaning se.
- Answer: wo chunks prompt mein jodo. Haan, wahi context window wali desk, Episode 2 se. Ab AI unhi chunks ko padhkar jawab deta hai, aur bata sakta hai ki kis source se liya.
RAG vs fine-tuning
- Fine-tuning = AI ko poori kitaab ratwana. Model khud badalta hai.
- RAG = AI ko bas sahi page khol kar dena. Model wahi rehta hai, sirf padhne ka material badalta hai.
Dhyan rahe
- Galat chunk mila, to jawab bhi galat.
- RAG jhooth kam karta hai, khatam nahi. Source khud check karo.
- Office ki files kisi tool mein daalne se pehle company ki policy dekh lo.
