Invoerflexibiliteit

Prompts als strings

response = client.responses.create(
    model="gpt-5-mini"
    input="How old is the Earth?",
    instructions="Answer concisely."
)

input → invoer van de gebruiker
instructions → gedrag + eisen

Rolgebaseerde prompts

response = client.responses.create(
    model="gpt-5-mini"
    input=[
        {"role": "system",
         "content": "Answer concisely."},
        {"role": "user",
         "content": "How old is the Earth?"}
    ]
)

Rolgebaseerde berichten

response = client.responses.create(
    model="gpt-5-mini"
    input=[

        {"role": "user", "content": "How old is the Sun?"},

        {"role": "assistant", "content": "4.603 billion years"},

        {"role": "user", "content": "How old is the Earth?"}

    ]
)

sys_prompt = "You are a helpful Teacher who provides concise, personalized explanations."
latest_response_id = None 

while True:
    user_input = input("You: ").strip()
    if user_input.lower() == "exit":
        break

        instructions=sys_prompt,
        input=user_input,
        previous_response_id=latest_response_id
    )

    print(f"\nAssistant: {response.output_text}\n")
    latest_response_id = response.id

messages = [{"role": "system"},
            {"content": "You are a helpful Teacher who provides concise, personalized explanations."}]


while True:
