Peran percakapan dengan format pesan

Array messages mensimulasikan percakapan multi-giliran
Tiap pesan memiliki peran
Mengikuti gaya respons tertentu

messages = [
    {"role": "user", 
 "content": "What's the weather like?"},
    {"role": "assistant", 
 "content": "I don't have access to 
     current weather data. You might 
     want to check a weather app."},
    {"role": "user", 
 "content": "How's traffic downtown?"}]

response = client.messages.create(
    model="claude-sonnet-4-20250514",
    messages=messages)

Pengantar few-shot prompting

Few-shot prompting mengajari Claude lewat contoh
Pasangan pesan user/assistant menunjukkan perilaku yang diinginkan
Efektif pada input baru

Seorang pengguna dan seorang asisten

Memahami zero-shot vs few-shot vs one-shot

Zero-shot: Satu prompt tanpa contoh
One-shot: Satu contoh sebelum tugas
Few-shot: Beberapa contoh menunjukkan pola
Lebih banyak contoh umumnya meningkatkan konsistensi

Contoh kode few-shot

messages = [{"role": "user", "content": "Translate to French: Hello"}] # Zero-shot

# One-shot  
messages = [{"role": "user", "content": "Translate to French: Good morning"},
    {"role": "assistant", "content": "Bonjour"},
    {"role": "user", "content": "Translate to French: Hello"}]

# Few-shot (beberapa contoh)
messages = [{"role": "user", "content": "Translate to French: Good morning"},
    {"role": "assistant", "content": "Bonjour"},
    {"role": "user", "content": "Translate to French: Thank you"},
    {"role": "assistant", "content": "Merci"},
    {"role": "user", "content": "Translate to French: Hello"}]

Aplikasi few-shot yang praktis

Konsistensi format: Tunjukkan struktur output yang diinginkan
Kesesuaian nada: Tiru gaya komunikasi tertentu
Penalaran kompleks: Pandu pemecahan masalah bertahap
Keahlian domain: Ajarkan penerapan pengetahuan khusus

# Mengajarkan format respons email
messages = [{"role": "user", "content": "Customer complaint: Late delivery"},
    {"role": "assistant", "content": "Dear Customer,\n\nWe apologize for the delay. 
     We'll track your order and update you within 24 hours.
     \n\nBest regards,\nSupport Team"},
    {"role": "user", "content": "Customer complaint: Wrong item received"}]

Praktik terbaik few-shot prompting

Prompting

Gunakan 2–5 contoh untuk sebagian besar tugas
Pastikan contoh berkualitas dan konsisten
Variasikan contoh untuk menonjolkan pola, bukan pengulangan
Uji kasus tepi untuk memastikan ketahanan
