Gemini API, Gemini मॉडल का इस्तेमाल करके, टेक्स्ट, इमेज, वीडियो, और ऑडियो जैसे अलग-अलग इनपुट से टेक्स्ट आउटपुट जनरेट कर सकता है.
यहां एक ऐसा बुनियादी उदाहरण दिया गया है जिसमें एक टेक्स्ट इनपुट लिया जाता है:
from google import genai
client = genai.Client(api_key="GEMINI_API_KEY")
response = client.models.generate_content(
model="gemini-2.0-flash",
contents=["How does AI work?"]
)
print(response.text)
import { GoogleGenAI } from "@google/genai";
const ai = new GoogleGenAI({ apiKey: "GEMINI_API_KEY" });
async function main() {
const response = await ai.models.generateContent({
model: "gemini-2.0-flash",
contents: "How does AI work?",
});
console.log(response.text);
}
await main();
package main
import (
"context"
"fmt"
"os"
"google.golang.org/genai"
)
func main() {
ctx := context.Background()
client, _ := genai.NewClient(ctx, &genai.ClientConfig{
APIKey: os.Getenv("GEMINI_API_KEY"),
Backend: genai.BackendGeminiAPI,
})
result, _ := client.Models.GenerateContent(
ctx,
"gemini-2.0-flash",
genai.Text("Explain how AI works in a few words"),
nil,
)
fmt.Println(result.Text())
}
curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=$GEMINI_API_KEY" \

-X POST \

// See https://developers.google.com/apps-script/guides/properties
// for instructions on how to set the API key.
const apiKey = PropertiesService.getScriptProperties().getProperty('GEMINI_API_KEY');
function main() {
const payload = {

const url = `https://generativelanguage.googleapis.com/v1beta/models/gemini-2.0-flash:generateContent?key=${apiKey}`;
const options = {

};
const response = UrlFetchApp.fetch(url, options);
const data = JSON.parse(response);
const content = data['candidates'][0]['content']['parts'][0]['text'];
console.log(content);
}
सिस्टम के निर्देश और कॉन्फ़िगरेशन
सिस्टम के निर्देशों की मदद से, Gemini मॉडल के व्यवहार को कंट्रोल किया जा सकता है. ऐसा करने के लिए, GenerateContentConfig
ऑब्जेक्ट पास करें.

मल्टीमोडल इनपुट
Gemini API, अलग-अलग तरह के इनपुट के साथ काम करता है. इसकी मदद से, टेक्स्ट को मीडिया फ़ाइलों के साथ जोड़ा जा सकता है. इस उदाहरण में, इमेज जोड़ने का तरीका बताया गया है:
from PIL import Image
from google import genai

image = Image.open("/path/to/organ.png")

इमेज उपलब्ध कराने के अन्य तरीकों और इमेज प्रोसेस करने के बेहतर तरीके के बारे में जानने के लिए, इमेज को समझने से जुड़ी गाइड देखें. यह एपीआई, दस्तावेज़, वीडियो, और ऑडियो के इनपुट और समझने की सुविधा भी देता है.
जवाब स्ट्रीम करना
डिफ़ॉल्ट रूप से, मॉडल सिर्फ़ तब जवाब देता है, जब जनरेट करने की पूरी प्रोसेस पूरी हो जाती है.
बेहतर इंटरैक्शन के लिए, स्ट्रीमिंग का इस्तेमाल करें, ताकि GenerateContentResponse
इंस्टेंस जनरेट होते ही, उन्हें धीरे-धीरे पाया जा सके.

एक से ज़्यादा बार की गई बातचीत (Chat)
हमारे SDK, चैट में कई राउंड के प्रॉम्प्ट और जवाब इकट्ठा करने की सुविधा देते हैं. इससे आपको बातचीत के इतिहास को ट्रैक करने में आसानी होती है.

काम करने वाले मॉडल
Gemini फ़ैमिली के सभी मॉडल, टेक्स्ट जनरेट करने की सुविधा के साथ काम करते हैं. मॉडल और उनकी सुविधाओं के बारे में ज़्यादा जानने के लिए, मॉडल पेज पर जाएं.
सबसे सही तरीके
प्रॉम्प्ट के बारे में सलाह
टेक्स्ट जनरेशन के बुनियादी लेवल के लिए, अक्सर ज़ीरो-शॉट प्रोम्प्ट काफ़ी होता है. इसके लिए, उदाहरणों, सिस्टम के निर्देशों या खास फ़ॉर्मैटिंग की ज़रूरत नहीं होती.
ज़्यादा काम के आउटपुट पाने के लिए:
- मॉडल को निर्देश देने के लिए, सिस्टम के निर्देश का इस्तेमाल करें.
- मॉडल को दिशा-निर्देश देने के लिए, इनपुट और आउटपुट के कुछ उदाहरण दें. इसे अक्सर फ़्यू-शॉट प्रॉम्प्टिंग कहा जाता है.
- इस्तेमाल के बेहतर उदाहरणों के लिए, बेहतर तरीके से इस्तेमाल करें.
ज़्यादा सलाह पाने के लिए, प्रॉम्प्ट इंजीनियरिंग गाइड देखें.
स्ट्रक्चर्ड आउटपुट
कुछ मामलों में, आपको JSON जैसे स्ट्रक्चर्ड आउटपुट की ज़रूरत पड़ सकती है. इसके बारे में जानने के लिए, स्ट्रक्चर्ड आउटपुट की गाइड देखें.
आगे क्या करना है
- Gemini API का इस्तेमाल शुरू करने के लिए Colab आज़माएं.
- Gemini की इमेज, वीडियो, ऑडियो और दस्तावेज़ को समझने की सुविधाओं के बारे में जानें.
- अलग-अलग तरीकों से फ़ाइल अपलोड करने के लिए कहा जाने वाला अनुरोध बनाने की रणनीतियों के बारे में जानें.
