כשהשקנו את משפחת המודלים של Gemini 2.0, השקנו גם קבוצה חדשה של ערכות SDK של Google Gen AI לעבודה עם Gemini API:
ערכות ה-SDK המעודכנות האלה יהיו תואמות באופן מלא לכל התכונות והמודלים של Gemini API, כולל התוספות האחרונות כמו Live API ו-Veo.
מומלץ להתחיל להעביר את הפרויקטים שלכם מ-SDKs הישנים של Gemini ל-SDKs החדשים של Gen AI. כדי לעזור לכם להתחיל, במדריך הזה מפורטות דוגמאות לקוד לפני ואחרי ההעברה. נמשיך להוסיף כאן דוגמאות שיעזרו לכם להתחיל להשתמש ב-SDK החדש.
התקנת ה-SDK
לפני
Python
pip install -U -q "google-generativeai"
JavaScript
npm install @google/generative-ai
אחרי
Python
pip install -U -q "google-genai"
JavaScript
npm install @google/genai
אמת
אימות באמצעות מפתח API. אפשר ליצור את מפתח ה-API ב-Google AI Studio.
לפני
Python
ה-SDK הישן טיפל באובייקט הלקוח של ה-API באופן משתמע. ב-SDK החדש יוצרים את לקוח ה-API ומשתמשים בו כדי לבצע קריאה ל-API. חשוב לזכור שבכל מקרה, ה-SDK יאסוף את מפתח ה-API משתנה הסביבה GOOGLE_API_KEY
אם לא מעבירים מפתח ללקוח.
import google.generativeai as genai
genai.configure(api_key=...)
JavaScript
import { GoogleGenerativeAI } from "@google/generative-ai";
const genAI = new GoogleGenerativeAI("GOOGLE_API_KEY");
אחרי
Python
export GOOGLE_API_KEY="YOUR_API_KEY"
from google import genai
client = genai.Client() # Set the API key using the GOOGLE_API_KEY env var.
# Alternatively, you could set the API key explicitly:
# client = genai.Client(api_key="your_api_key")
JavaScript
import { GoogleGenAI } from "@google/genai";
const ai = new GoogleGenAI({apiKey: "GEMINI_API_KEY"});
יצירת תוכן
לפני
Python
ערכת ה-SDK החדשה מספקת גישה לכל שיטות ה-API דרך האובייקט Client
. מלבד כמה מקרים מיוחדים עם מצב (chat
ו-session
של API פעיל), כל הפונקציות האלה הן ללא מצב. כדי לשמור על יעילות ועל אחידות, האובייקטים שמוחזרים הם מחלקות pydantic
.
import google.generativeai as genai
model = genai.GenerativeModel('gemini-1.5-flash')
response = model.generate_content(
'Tell me a story in 300 words'
)
print(response.text)
JavaScript
import { GoogleGenerativeAI } from "@google/generative-ai";
const genAI = new GoogleGenerativeAI(process.env.API_KEY);
const model = genAI.getGenerativeModel({ model: "gemini-1.5-flash" });
const prompt = "Tell me a story in 300 words";
const result = await model.generateContent(prompt);
console.log(result.response.text());
אחרי
Python
from google import genai
client = genai.Client()
response = client.models.generate_content(
model='gemini-2.0-flash',
contents='Tell me a story in 300 words.'
)
print(response.text)
print(response.model_dump_json(
exclude_none=True, indent=4))

const ai = new GoogleGenAI({ apiKey: "GOOGLE_API_KEY" });
const response = await ai.models.generateContent({
model: "gemini-2.0-flash",
contents: "Tell me a story in 300 words.",
});
console.log(response.text);
לפני
Python
רבות מהתכונות הנוחות הקיימות ב-SDK הקודם קיימות גם ב-SDK החדש. לדוגמה, אובייקטים מסוג PIL.Image
מומרים באופן אוטומטי.
import google.generativeai as genai
model = genai.GenerativeModel('gemini-1.5-flash')
response = model.generate_content([
'Tell me a story based on this image',
Image.open(image_path)
])

import { GoogleGenerativeAI } from "@google/generative-ai";
const genAI = new GoogleGenerativeAI("GOOGLE_API_KEY");
const model = genAI.getGenerativeModel({ model: "gemini-1.5-flash" });
function fileToGenerativePart(path, mimeType) {
return {
inlineData: {
data: Buffer.from(fs.readFileSync(path)).toString("base64"),
mimeType,
},
};
}
const prompt = "Tell me a story based on this image";
const imagePart = fileToGenerativePart(
`path/to/organ.jpg`,
"image/jpeg",
);
const result = await model.generateContent([prompt, imagePart]);
console.log(result.response.text());
אחרי
Python

client = genai.Client()

תגובת JSON
יצירת תשובות בפורמט JSON.
לפני
Python
על ידי ציון response_schema
והגדרה של response_mime_type="application/json"
, המשתמשים יכולים להגביל את המודל כך שיפיק תגובה JSON
לפי מבנה נתון. ה-SDK החדש משתמש ב-pydantic
classes כדי לספק את הסכימה (אבל אפשר להעביר genai.types.Schema
או dict
מקביל). כשהדבר אפשרי, ה-SDK ינתח את ה-JSON המוחזר ויחזיר את התוצאה ב-response.parsed
. אם סיפקתם את המחלקה pydantic
כהסכימה, ה-SDK יהפוך את JSON
למכונה של המחלקה.
