Google GenAI SDK-তে মাইগ্রেট করুন

২০২৪ সালের শেষের দিকে Gemini 2.0 রিলিজের মাধ্যমে, আমরা Google GenAI SDK নামে লাইব্রেরির একটি নতুন সেট নিয়ে এসেছি। এটি আপডেট করা ক্লায়েন্ট আর্কিটেকচার-এর মাধ্যমে ডেভেলপারদের আরও উন্নত অভিজ্ঞতা প্রদান করে এবং ডেভেলপার ও এন্টারপ্রাইজ ওয়ার্কফ্লোর মধ্যে ট্রানজিশন সহজ করে তোলে।

Google GenAI SDK এখন সব কাজ করে এমন প্ল্যাটফর্ম জুড়ে জেনেরাল অ্যাভেইলেবিলিটি (GA)-তে উপলভ্য। আপনি আমাদের কোনও পুরনো লাইব্রেরি ব্যবহার করলে, আমরা আপনাকে মাইগ্রেট করার জন্য সাজেস্ট করছি।

এই নির্দেশিকা আপনাকে শুরু করতে সাহায্য করার জন্য মাইগ্রেট করা কোডের আগে এবং পরের উদাহরণ প্রদান করে।

API অ্যাক্সেস

পুরনো SDK বিভিন্ন অ্যাডহক পদ্ধতি ব্যবহার করে ব্যাকগ্রাউন্ডে API ক্লায়েন্টকে পরোক্ষভাবে ম্যানেজ করত। এর ফলে ক্লায়েন্ট ও ক্রেডেনশিয়াল ম্যানেজ করা কঠিন হয়ে যায়। এখন, আপনি একটি সেন্ট্রাল Client অবজেক্টের মাধ্যমে ইন্টার‍্যাক্ট করেন। এই Client অবজেক্ট বিভিন্ন API পরিষেবার (যেমন, models, chats, files, tunings) জন্য একটি এন্ট্রি পয়েন্ট হিসেবে কাজ করে এবং বিভিন্ন API কলের মধ্যে সামঞ্জস্য বজায় রাখা ও ক্রেডেনশিয়াল এবং কনফিগারেশন ম্যানেজমেন্টকে সহজ করে তোলে।

আগে (কম সেন্ট্রালাইজড API অ্যাক্সেস)

Python

পুরানো SDK বেশিরভাগ API কলের জন্য স্পষ্টভাবে টপ-লেভেল ক্লায়েন্ট অবজেক্ট ব্যবহার করেনি। আপনি সরাসরি GenerativeModel অবজেক্ট ইনস্ট্যানশিয়েট ও ইন্টার‍্যাক্ট করতে পারবেন।

import google.generativeai as genai

# Directly create and use model objects
model = genai.GenerativeModel('gemini-3.8-flash')
response = model.generate_content(...)
chat = model.start_chat(...)

GoogleGenerativeAI মডেল ও চ্যাটের জন্য সেন্ট্রাল পয়েন্ট হলেও, ফাইল ও ক্যাশে ম্যানেজমেন্টের মতো অন্যান্য ফাংশনালিটির জন্য প্রায়ই সম্পূর্ণ আলাদা ক্লায়েন্ট ক্লাস ইমপোর্ট ও ইনস্ট্যান্টিয়েট করতে হয়।

genai.NewClient ফাংশন একটি ক্লায়েন্ট তৈরি করেছে, কিন্তু জেনারেটিভ মডেল অপারেশন সাধারণত এই ক্লায়েন্ট থেকে পাওয়া একটি পৃথক GenerativeModel ইনস্ট্যান্সে কল করা হয়েছিল। অন্যান্য পরিষেবা হয়ত আলাদা প্যাকেজ বা প্যাটার্নের মাধ্যমে অ্যাক্সেস করা হয়েছে।

যাচাইকরণ

পুরনো ও নতুন, দুই ধরনের লাইব্রেরিই API কী ব্যবহার করে যাচাই করে। আপনি Google AI Studio-তে API কী তৈরি করতে পারবেন।

আগে

Python

পুরনো SDK, API ক্লায়েন্ট অবজেক্টকে অন্তর্নিহিতভাবে ম্যানেজ করত।

import google.generativeai as genai

genai.configure(api_key=...)

জাভাস্ক্রিপ্ট

import { GoogleGenerativeAI } from "@google/generative-ai";

const genAI = new GoogleGenerativeAI("GEMINI_API_KEY");

Java

import com.google.genai.Client;

// Passing the API key explicitly to the client builder
Client client = Client.builder().apiKey("GEMINI_API_KEY").build();

খুলুন

Google লাইব্রেরি ইমপোর্ট করুন:

import (
      "github.com/google/generative-ai-go/genai"
      "google.golang.org/api/option"
)

ক্লায়েন্ট তৈরি করুন:

client, err := genai.NewClient(ctx, option.WithAPIKey("GEMINI_API_KEY"))

পরে

Python

Google GenAI SDK-এর মাধ্যমে, আপনি প্রথমে একটি API ক্লায়েন্ট তৈরি করেন, যা API কল করতে ব্যবহৃত হয়। আপনি ক্লায়েন্টকে কোনও API কী না দিলে, নতুন SDK আপনার API কী GEMINI_API_KEY এনভায়রনমেন্ট ভেরিয়েবল থেকে নেবে।

export GEMINI_API_KEY="YOUR_API_KEY"
from google import genai

client = genai.Client() # Set the API key using the GEMINI_API_KEY env var.
                        # Alternatively, you could set the API key explicitly:
                        # client = genai.Client(api_key="YOUR_API_KEY")

জাভাস্ক্রিপ্ট

import { GoogleGenAI } from "@google/genai";

const ai = new GoogleGenAI({apiKey: "GEMINI_API_KEY"});

Java

import com.google.genai.Client;

// The client automatically picks up the GEMINI_API_KEY environment variable,
// or you can pass it explicitly via Client.builder().apiKey("GEMINI_API_KEY").build()
Client client = new Client();

খুলুন

GenAI লাইব্রেরি ইমপোর্ট করুন:

import "google.golang.org/genai"

ক্লায়েন্ট তৈরি করুন:

client, err := genai.NewClient(ctx, &genai.ClientConfig{
