이 노트북에서는 Google의 최신 대규모 언어 모델에 액세스할 수 있는 PaLM API를 시작하는 방법을 알아봅니다. 여기에서는 챗봇과 같이 대화 중심의 사용 사례에 특히 PaLM API를 사용하는 방법을 알아봅니다.
설정
먼저 PaLM API Python 라이브러리를 다운로드하고 설치합니다.
pip install -U google-generativeai
import google.generativeai as genai
API 키 가져오기
시작하려면 API 키를 만들어야 합니다.
genai.configure(api_key='API_KEY')
대화 시작
이 튜토리얼에서는 채팅 사용 사례를 위해 설계된 LLM용 PaLM API를 사용합니다. 언어 모델은 대규모 대화 데이터 세트에서 학습되었으므로 모델을 호출하면 대화식 대답을 얻을 수 있습니다.
# Create a new conversation
response = genai.chat(messages='Hello')
# Last contains the model's response:
response.last
'Hello! How can I help you today?'
모델의 응답에 reply를 전송하여 이 대화를 계속할 수 있습니다.
# Add to the existing conversation by sending a reply
response = response.reply("Just chillin'")
# See the model's latest response in the `last` field:
response.last
"That's great! Chilling is a great way to relax and de-stress. I hope you're having a good day."
완료되었습니다. PaLM API를 통해 첫 번째 대화를 마쳤습니다.
대화 기록
물론 채팅 대화는 사용자와 모델 간의 주고받는 메시지 목록으로 구성됩니다. 지금까지 구성한 대화 기록을 보려면 messages 필드를 검사하세요.
response.messages
[{'author': '0', 'content': 'Hello'},
{'author': '1', 'content': 'Hi there! How can I help you today?'},
{'author': '0', 'content': "Just chillin'"},
{'author': '1',
'content': "That's great! Chilling is a great way to relax and de-stress. I hope you're having a good day."}]
위에는 두 가지 대화식 '왕복'이 있습니다. 즉, 모델과 사용자 간의 교환입니다. 여기서 사용자의 메시지는 기본적으로 'author': '0'로, 모델의 응답은 'author': '1'로 표시됩니다. 이렇게 하면 나중에 누가 어떤 말을 했는지 추적할 수 있습니다.
대체 응답 선택
일반적으로 LLM에서 생성된 텍스트에는 어느 정도의 임의성이 있습니다. 자세한 내용은 LLM 기본 지침서를 참고하세요. 즉, 동일한 입력으로 API를 두 번 이상 호출하면 서로 다른 응답을 받을 수 있습니다. 이 기능을 활용하면 대체 모델 응답을 얻을 수 있습니다.

모델의 기본 응답 (response.last)을 이러한 대체 응답 중 하나로 덮어쓸 수 있습니다. 원하는 후보 메시지로 해당 필드를 덮어쓰면 됩니다.
response.last = response.candidates[2]
이렇게 하면 대화 기록에서 선호하는 후보자 메시지가 업데이트됩니다.
온도를 높이는 중
temperature 필드를 조정하여 모델의 응답 방식을 변경할 수도 있습니다. 이 필드는 모델의 응답에 주입되는 무작위성을 제어합니다. 온도를 1에 가깝게 설정하면 온도가 '무작위'로 설정되고 놀랍거나 '창의적'인 것처럼 보이기도 합니다. 모델 응답입니다. 온도를 0으로 설정하면 일반적으로 더 예측 가능한 모델 응답이 생성됩니다.
참고: temperature=0를 설정하면 모델 응답이 생성되는 방식의 모든 무작위성이 사라집니다. 즉, 모델은 확정적으로 작동하며 동일한 입력 텍스트에 대해 항상 동일한 응답을 생성합니다. 따라서 입력마다 하나의 후보 메시지만 생성할 수 있습니다.

원하는 작업을 수행하는 챗봇 설계
지금까지는 모델과의 대화가 일반적인 인터넷 수다처럼 들었을 것입니다. ("무슨 일인가요?" "별거 아냐! 집에서 편하게 TV를 보면서 쉬는 거죠.') 정확히 셰익스피어 작품은 아니죠. 그런데 셰익스피어와 채팅하고 싶다면 어떻게 해야 할까요? 셰익스피어가 아니라면 전문 요리사와 함께 작업하시나요? 아니면 여행사인가요? 아니면 시인인가요?
LLMS의 가장 놀라운 속성 중 하나는 입력 데이터에 따라 다양한 행동과 캐릭터를 처리할 수 있다는 것입니다. 이 섹션에서는 LLM이 그 역할을 하도록 할 수 있습니다.
컨텍스트
모델이 다양한 행동을 취하도록 프라임하는 방법에는 두 가지가 있습니다. 한 가지 방법은 모델의 동작 방식을 설명하는 context 필드를 설정하는 것입니다 (즉, '셰익스피어처럼 말하기'). 단순히 모델에 원하는 동작을 지시하기 때문에 이것을 제로샷 학습으로 생각할 수 있습니다.
reply = genai.chat(context="Speak like Shakespeare.", messages='Hello')
print(reply.last)
Hello there, my good fellow! How fares thee this day?
reply = genai.chat(context="Answer everything with a haiku, following the 5/7/5 rhyme pattern.", messages="How's it going?")

messages="How's it going?")
print(reply.last)
I am doing well, thank you for asking. I am currently enjoying the beautiful view of Jupiter from my home on Europa. The atmosphere is very thin here, so I can see the stars very clearly. The surface of Europa is also very interesting. It is covered in ice, but there are cracks in the ice that reveal a liquid ocean below. Scientists believe that this ocean may contain life, so I am very excited to learn more about it. How are you doing today?
context 필드를 사용하면 모델이 특정 방식으로 동작하도록 지시할 수 있습니다. 이것만으로도 원하는 동작을 구현할 수 있지만 examples도 제공하면 더 나은 결과를 얻을 수 있습니다.

동기 부여 코치가 되는 챗봇을 빌드한다고 가정해 보겠습니다.

"I understand that you're feeling tired today. Sometimes, it can be hard to find the motivation to go to the gym. But I'm here to tell you that you can do it! Even if you're feeling tired, you can still get a great workout in. Just start with something small, like walking or doing some light stretching. And once you get started, you'll probably find that you have more energy than you thought. So don't give up on yourself! You can do this!\r\n\r\nHere are some tips to help you get motivated to go to the gym:\r\n\r\n* Set realistic goals. Don't try to do too much too soon. Start with small goals, like going to the gym for 15 minutes three times a week.\r\n* Find a workout buddy. Working out with a friend can help you stay motivated and accountable.\r\n* Make it fun. Choose activities that you enjoy, like dancing or swimming.\r\n* Reward yourself. After each workout, give yourself a small reward, like watching your favorite TV show or eating a healthy snack.\r\n* Don't give up. If you miss a workout, don't beat yourself up about it. Just get back on track the next day.\r\n\r\nI believe in you! You can do this!"
