با انتشار Gemini 2.0 در اواخر سال ۲۰۲۴، مجموعه جدیدی از کتابخانهها را با نام Google GenAI SDK معرفی کردیم. این نسخه ازطریق معماری کلاینت بهروزشده، تجربه توسعهدهنده را بهبود میبخشد و انتقال بین گردشهای کاری توسعهدهنده و سازمانی را ساده میکند.
کیت توسعه نرمافزار Google GenAI اکنون در دسترس عموم (GA) در همه پلاتفرمهای پشتیبانیشده قرار دارد. اگر از یکی از کتابخانههای قدیمی ما استفاده میکنید، اکیداً توصیه میکنیم که مهاجرت کنید.
این راهنما نمونههایی از کد انتقالیافته قبل و بعداز انتقال ارائه میدهد تا به شما در شروع کار کمک کند.

دسترسی API
«کیت توسعه نرمافزار» قدیمی بهطور ضمنی مشتری «میانای برنامهسازی کاربردی» را در پشت صحنه بااستفاده از روشهای موقت مختلفی مدیریت میکرد. این کار مدیریت کارخواه و اعتبارنامهها را دشوار میکرد.
اکنون ازطریق یک شیء مرکزی Client تعامل میکنید. این شیء Client بهعنوان یک نقطه ورود واحد برای سرویسهای مختلف API (برای نمونه، models، chats،
files، tunings) عمل میکند و باعث میشود مدیریت اعتبار و پیکربندی در تماسهای مختلف API سادهتر و یکپارچهتر شود.
قبلاز (دسترسی کمتر متمرکز به API)
Python
کیت توسعه نرمافزار قدیمی بهطور صریح از شیء کارخواه سطح بالا برای اکثر فراخوانیهای میانای برنامهسازی کاربردی استفاده نمیکرد. مستقیماً نمونهسازی میکنید و با GenerativeModel
اشیا تعامل میکنید.
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(...)
JavaScript
درحالیکه GoogleGenerativeAI نقطه مرکزی برای مدلها و گپ بود، سایر
عملکردها مانند مدیریت فایل و حافظه نهان اغلب نیاز به وارد کردن و
نمونهسازی کلاسهای مشتری کاملاً جداگانه داشتند.
import { GoogleGenerativeAI } from "@google/generative-ai";

const cacheManager = new GoogleAICacheManager("GEMINI_API_KEY");
// Get a model instance, then call methods on it
const model = genAI.getGenerativeModel({ model: "gemini-3.8-flash" });
const result = await model.generateContent(...);
const chat = model.startChat(...);
// Call methods on separate client objects for other services
const uploadedFile = await fileManager.uploadFile(...);
const cache = await cacheManager.create(...);

GenerateContentResponse response =
client.models.generateContent("gemini-3.8-flash", "Tell me a story.", null);
Chat chat = client.chats.create("gemini-3.8-flash");

تابع genai.NewClient یک کارخواه ایجاد کرد، اما عملیات مدل زایا معمولاً در نمونه GenerativeModel جداگانهای که از این کارخواه بهدست آمده بود فراخوانی میشد. ممکن است سرویسهای دیگر ازطریق بستهها یا الگوهای متمایز دسترسی پیدا کرده باشند.

با Google GenAI SDK، ابتدا یک کارخواه API ایجاد میکنید که برای فراخوانی
میانای برنامهسازی کاربردی استفاده میشود.
اگر کلید میانای برنامهسازی کاربردی را به کارخواه ارسال نکنید، کیت توسعه نرمافزار جدید کلید میانای برنامهسازی کاربردی شما را از متغیرهای محیطی GEMINI_API_KEY دریافت خواهد کرد.
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:
