PaLM API'den Gemini API'ye geçiş

Bu kılavuzda, Python kodunuzu PaLM API'den Gemini API'ye nasıl taşıyacağınız gösterilmektedir. Gemini ile hem yazılı görüşmeler hem de çok dönüşlü görüşmeler (sohbet) oluşturabilirsiniz. Ancak, yanıtlarınız PaLM çıkışlarından farklı olabileceği için mutlaka kontrol edin.

API farklılıklarının özeti

  1. Yöntem adları değişti. Metin ve sohbet oluşturmak için ayrı yöntemler kullanmak yerine, bunların ikisini birden yapabilen tek bir generate_content yöntemi vardır.
  2. Chat, sohbet işlemini kolaylaştıran start_chat yardımcı bir yöntem sunar.
  3. Yeni API'ler, bağımsız işlevler yerine GenerativeModel sınıfının yöntemleridir.
  4. Çıkış yanıtı yapısı değişti.
  5. Güvenlik ayarı kategorileri değişti. Ayrıntılar için güvenlik ayarları kılavuzuna bakın.

Metin Oluşturma: Temel

palm.configure(
    api_key=os.environ['API_KEY'])

response = palm.generate_text(
    prompt="The opposite of hot is")
print(response.result) #  'cold.'
        
pip install google-generativeai

import google.generativeai as genai
import os

genai.configure(
    api_key=os.environ['API_KEY'])
model = genai.GenerativeModel(
    model_name='gemini-pro')

response = model.generate_content(
          'The opposite of hot is')
print(response.text)
    #  The opposite of hot is cold.'
