শুরু করা

এই নির্দেশিকা আপনাকে Interactions API ব্যবহার করে Gemini API-এর সাথে শুরু করতে সাহায্য করে। আপনি এক মিনিটের মধ্যেই প্রথম API কল করবেন এবং টেক্সট জেনারেশন, মাল্টিমোডাল আন্ডারস্ট্যান্ডিং, ইমেজ জেনারেশন, স্ট্রাকচার্ড আউটপুট, টুল, ফাংশন কলিং, এজেন্ট ও ব্যাকগ্রাউন্ড এক্সিকিউশন এক্সপ্লোর করবেন।

Interactions API Python ও JavaScript SDK এবং REST-এর মাধ্যমে উপলভ্য।

১. API key পাওয়া

Gemini API ব্যবহার করতে, আপনার অনুরোধ যাচাই করতে, নিরাপত্তা সংক্রান্ত সীমা প্রয়োগ করতে এবং আপনার অ্যাকাউন্টে ব্যবহার ট্র্যাক করতে, আপনার একটি API কী থাকতে হবে।

  • নতুন ব্যবহারকারীদের জন্য Google AI Studio অটোমেটিক প্রোজেক্ট ও API কী তৈরি করে। আপনি এটি API 'কী' পৃষ্ঠা থেকে কপি করতে পারবেন।
  • আপনার নতুন কী প্রয়োজন হলে, AI Studio-তে API কী তৈরি করুন বিকল্পে ক্লিক করুন এবং নতুন কী-প্রোজেক্ট পেয়ার যোগ করতে ডায়ালগ অনুসরণ করুন।

Gemini API কী তৈরি করা

আপনার কী এনভায়রনমেন্ট ভেরিয়েবল হিসেবে সেট করুন:

export GEMINI_API_KEY="YOUR_API_KEY"

পেড টিয়ারে আপগ্রেড করা

পেড টিয়ারে আপগ্রেড করলে আপনার রেট লিমিট বেড়ে যায় এবং এর জন্য Cloud Billing সেট-আপ করতে হয়।

  • AI Studio API কী বা প্রোজেক্ট পৃষ্ঠায় বিলিং সেট-আপ করুন বিকল্পে ক্লিক করুন।
  • বিলিং অ্যাকাউন্ট তৈরি বা লিঙ্ক করতে, পেমেন্ট পদ্ধতি যোগ করতে এবং পেড ক্রেডিট হিসেবে কমপক্ষে $৫ (বা সমতুল্য মুদ্রা) প্রিপে করতে Cloud Billing ডায়ালগ ফলো করুন।
  • Google AI Studio-তে আপনার API ব্যবহার দেখুন ড্যাশবোর্ড > ব্যবহার বিকল্পের অধীনে।

আরও তথ্যের জন্য বিলিং পৃষ্ঠা দেখুন।

২. SDK ইনস্টল করুন এবং প্রথম কল করুন

SDK ইনস্টল করুন এবং একটি API কলের মাধ্যমে টেক্সট জেনারেট করুন।

Python

SDK ইনস্টল করুন:

pip install -U google-genai

ক্লায়েন্টকে ইনিশিয়ালাইজ করুন এবং অনুরোধ করুন:

from google import genai

client = genai.Client()

interaction = client.interactions.create(
    model="gemini-3.8-flash",
    input="Explain how AI works in a few words"
)
print(interaction.output_text)

জাভাস্ক্রিপ্ট

SDK ইনস্টল করুন:

npm install @google/genai

ক্লায়েন্টকে ইনিশিয়ালাইজ করুন এবং অনুরোধ করুন:

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

const ai = new GoogleGenAI({});

const interaction = await ai.interactions.create({
  model: "gemini-3.8-flash",
  input: "Explain how AI works in a few words",
});
console.log(interaction.output_text);

        .build();

Interaction interaction =

System.out.println(interaction.outputText().orElse(""));

REST ব্যবহার করার সময়, API সম্পূর্ণ Interaction রিসোর্স রিটার্ন করে, যার মধ্যে মেটাডেটা, ব্যবহারের পরিসংখ্যান এবং টার্নের স্টেপ-বাই-স্টেপ ইতিহাস থাকে।

SDK সম্পূর্ণ উত্তর দেখালেও, সরাসরি চূড়ান্ত আউটপুট অ্যাক্সেস করার জন্য interaction.output_text এবং interaction.output_image-এর মতো সুবিধাজনক প্রপার্টি প্রদান করে। ইন্টার‍্যাকশন ওভারভিউ থেকে উত্তর দেওয়ার গঠন সম্পর্কে আরও জানুন অথবা সিস্টেম নির্দেশাবলী ও জেনারেশন কনফিগারেশন সম্পর্কে বিস্তারিত জানতে টেক্সট জেনারেশন গাইড পড়ুন।

৩. উত্তর স্ট্রিম করা

আরও সাবলীল ইন্টার‍্যাকশনের জন্য, উত্তর জেনারেট হওয়ার সাথে সাথেই তা স্ট্রিম করুন। প্রতিটি step.delta ইভেন্ট টেক্সটের একটি অংশ ডেলিভার করে যা আপনি সঙ্গে সঙ্গে দেখাতে পারেন।

৪. একাধিক কথোপকথন

Interaction API-তে দুটি পদ্ধতির মাধ্যমে মাল্টি-টার্ন কথোপকথন করা যায়:

  • স্টেটফুল (সাজেস্ট করা): previous_interaction_id ব্যবহার করে সার্ভারে কথোপকথন চালিয়ে যান। বেশিরভাগ চ্যাট ও এজেন্টিক ওয়ার্কফ্লোয়ের জন্য আদর্শ, যেখানে আপনি চান যে সার্ভার ইতিহাস ম্যানেজ করুক এবং ক্যাশিং অপ্টিমাইজ করুক।
  • স্টেটলেস: প্রতিটি অনুরোধে আগের সবকটি টার্ন (এর মধ্যে অন্তর্বর্তী মডেলের চিন্তাভাবনা ও টুলের ধাপ অন্তর্ভুক্ত) পাস করার মাধ্যমে ক্লায়েন্টে কথোপকথনের ইতিহাস ম্যানেজ করুন।

previous_interaction_id পাস করার মাধ্যমে ইন্টার‍্যাকশন চেইন করুন। সার্ভার আপনার জন্য সম্পূর্ণ কথোপকথনের ইতিহাস ম্যানেজ করে।

  1. প্রাথমিক user_input ধাপ।
  2. ১ম রাউন্ডে মডেল-জেনারেটেড সব ধাপ (thought ও function_call ধাপ সহ) ঠিক যেভাবে পাওয়া গেছে সেইভাবেই ফেরত দেওয়া হয়েছে।
  3. আপনার এক্সিকিউট করা ফাংশনের আউটপুট সহ function_result ধাপ।

উত্তর:

প্রাথমিক উত্তরটি স্ট্যাটাস in_progress সহ সাথে সাথেই ফেরত আসে:

{
  "id": "v1_abc123",
  "status": "in_progress",
  "object": "interaction",
  "model": "gemini-3.8-flash"
}

ব্যাকগ্রাউন্ড টাস্ক সম্পূর্ণ হয়ে গেলে, ইন্ট্যার‍্যাকশন স্টেট চেক করলে এই ভ্যালু রিটার্ন করে:

{
  "id": "v1_abc123",
  "status": "completed",
  "steps": [
    {
      "type": "model_output",
      "content": [
        {
          "type": "text",
          "text": "Artificial intelligence has transformed modern healthcare in several..."
        }
      ]
    }
  ],
  "object": "interaction",
  "model": "gemini-3.8-flash",
}

ব্যাকগ্রাউন্ড এক্সিকিউশন গাইড থেকে অ্যাসিঙ্ক্রোনাস মডেল ও এজেন্ট রান করা সম্পর্কে জানুন।

এর পরে কী করতে হবে

  • ব্যাকগ্রাউন্ড এক্সিকিউশন: দীর্ঘ সময় ধরে চলতে থাকা টাস্ক অ্যাসিঙ্ক্রোনাসভাবে চালান এবং স্টেট ম্যানেজ করুন।
  • টেক্সট জেনারেশন: সিস্টেম নির্দেশাবলী, জেনারেশন কনফিগারেশন ও উন্নত টেক্সট প্যাটার্ন।
  • ছবি তৈরি করা: অ্যাস্পেক্ট রেশিও, ছবি এডিট করা এবং স্টাইল রেফারেন্স।
  • ছবি বোঝা: শ্রেণীবিভাগ, অবজেক্ট শনাক্তকরণ এবং ভিজ্যুয়াল প্রশ্ন ও উত্তর।
  • চিন্তাভাবনা: জটিল টাস্কের জন্য চেন-অফ-থট রিজনিং ব্যবহার করো।
  • ফাংশন কলিং: প্যারালাল, কম্পোজিশনাল ও কনস্ট্রেন্ট ফাংশন মোড।
  • Google Search: গ্রাউন্ডিং, উদ্ধৃতি ও সার্চ সাজেশন।
  • ম্যানেজ করা এজেন্ট: কোড এক্সিকিউশন ও ফাইল ম্যানেজমেন্ট সহ আগে থেকে তৈরি এজেন্ট।
  • Deep Research: প্ল্যানিং ও সিন্থেসিস সহ অটোনোমাস মাল্টি-স্টেপ রিসার্চ।
  • স্ট্রাকচার্ড আউটপুট: JSON স্কিমা, এনুম ও রিকার্সিভ টাইপ ডেফিনিশন।
