Aaj kal har koi Artificial Intelligence (AI) ki baat kar raha hai, aur aap bhi soch rahay hon gay keh yeh sab kya hai aur isse kya faida utha sakta hai. Ek exciting cheez jo AI nay humaray liye mumkin banayi hai woh hai apnay khud ke AI apps banana! Ab aap soch rahay hon gay keh yeh kaise mumkin hai? To is ka jawab hai Langchain.

Is blog post mein, hum Langchain ko ghor se samjhen gay - yeh kya hai, yeh kaise kaam karta hai, aur iski madad se aap kaise apnay khud ke AI apps bana saktay hain. Chaliye shuru karte hain!

Langchain: Ek Jhalak

Langchain ek framework hai jo large language models (LLMs) ke saath kaam karta hai. LLMs basically AI systems hain jo bahut saara data analyze kar ke insaanon ki tarah text generate kar saktay hain, jese Google ka "Bard" aur OpenAI ka "ChatGPT".

Langchain aapko yeh power deta hai keh aap LLMs ki yeh capability ko apnay apps mein use kar sakay. Isse aap aise apps bana saktay hain jo:

  • Sawalon ke jawab detay hain (Chatbots)
  • Text summarize kartay hain
  • Different languages mein translate kartay hain
  • Creative content generate kartay hain (kahaniyan, poems, etc.)
  • Aur bahut kuch!

Langchain Ke Modules

Langchain ki khoobi yeh hai keh is mein alag alag modules hain jo aapko different functionalities provide karte hain:

  1. Models: Langchain aapko different LLMs ke saath kaam karne ki flexibility deta hai. Aap OpenAI, Google, Hugging Face, aur doosre providers ke models use kar saktay hain.
  2. Prompts: LLMs ko sahi output dene ke liye sahi input dena bahut zaroori hai. Langchain aapko "prompt templates" banane ki facility deta hai jisse aap LLMs ko behtar instructions de saktay hain.
  3. Memory: Agar aap chahtay hain keh aapka app pehle ke interactions ko yaad rakhay (jese ek chatbot mein), to Langchain aapko "memory" manage karne ki facility bhi deta hai.
  4. Indices: Agar aap apne AI app ko apne khud ke data se train karna chahtay hain, to aapko us data ko LLMs ke liye accessible banana hoga. Langchain mein "indices" ka module aapko yeh karne mein madad karta hai.
  5. Chains: Aik complex task ko pura karne ke liye aksar kai steps ki zaroorat hoti hai. Langchain aapko "chains" banane ki facility deta hai jisse aap multiple LLMs, prompts, aur tools ko ek saath use kar saktay hain.
  6. Agents: Agar aap chahtay hain keh aapka AI app khud hi decide kare keh kon sa tool use karna hai ek specific task ke liye, to aap Langchain ke "agents" ka use kar saktay hain.

Langchain Ka Use Karke Apna Pehla AI App Banayen

Ab chaliye dekhte hain keh Langchain ka use karke ek basic AI app kaise banaya ja sakta hai jo sawalon ke jawab deta hai:

Step 1: Zaroori Packages Install Karein

Pehle aapko apne system pe Python aur Langchain install karna hoga. Yeh kaise karna hai iski instructions aapko Langchain ki website pe mil jayengi: https://python.langchain.com/

Step 2: Apna Python Code Likhein

from langchain.llms import OpenAI from langchain import PromptTemplate, LLMChain # OpenAI API key set karein # Aap apni key OpenAI ki website se le saktay hain openai_api_key = "YOUR_API_KEY" # LLM initialize karein llm = OpenAI(openai_api_key=openai_api_key) # Prompt template define karein template = """ Question: {question} Answer: """ # Prompt template ko LLM se connect karein prompt = PromptTemplate( input_variables=["question"], template=template, ) # Chain initialize karein llm_chain = LLMChain(llm=llm, prompt=prompt) # User se question poochein question = input("Apna sawal poochein: ") # AI se jawab generate karein response = llm_chain.run(question) # Jawab print karein print(response)

Step 3: Code Run Karein

Jab aap yeh code run karengay, to yeh aapse ek sawal poochega. Aap koi bhi sawal pooch saktay hain aur AI aapko us ka jawab dega.

Note: Is code mein humne OpenAI ka LLM use kiya hai. Agar aap koi aur LLM use karna chahtay hain to aapko code mein thodi si change karni hogi.

Langchain: AI Ki Duniya Mein Aapki Ticket

Langchain ek powerful tool hai jisse aap AI ki duniya mein apna pehla qadam rakh saktay hain. Iski madad se aap bina kisi mushkil coding ke apnay khud ke AI apps bana saktay hain. To der kis baat ki? Aaj hi Langchain ko try karein aur apne creative ideas ko haqeeqat mein badlein!
