Parámetro reasoning

​

Regla práctica

• Si solo deseas razonamiento más fuerte, envía effort
• Si necesitas un resumen de razonamiento inspeccionable, envía ambos effort y summary

• solo con effort, el ítem reasoning existía pero summary podría ser un arreglo vacío
• con summary: "detailed", summary_text se devolvía confiablemente

​

Extraer el resumen del pensamiento

response = client.responses.create(
    model="gpt-5.5",
    input="Design a high-concurrency message queue architecture.",
    reasoning={
        "effort": "high",
        "summary": "detailed"
    }
)

for item in response.output:
    if item.type == "reasoning":
        for part in item.summary:
            if part.type == "summary_text":
                print("Thinking summary:", part.text)
    elif item.type == "message":
        for content in item.content:
            if content.type == "output_text":
                print("Final answer:", content.text)

Pensamiento en streaming

• response.reasoning_summary_part.added
• response.reasoning_summary_text.delta
• response.reasoning_summary_text.done
• response.output_text.delta
• response.output_text.done
• response.completed

stream = client.responses.create(
    model="gpt-5.5",
    input="Explain briefly why 9.9 is larger than 9.11.",
    reasoning={
        "effort": "high",
        "summary": "detailed"
    },
    stream=True
)

for event in stream:
    if event.type == "response.reasoning_summary_text.delta":
        print(f"[Thinking summary] {event.delta}", end="")
    elif event.type == "response.output_text.delta":
        print(event.delta, end="")

Recomendación actual

• Si necesitas un campo visible de razonamiento, prefiere gpt-5.5 con la API de Respuestas
• No trates gpt-5.5 Chat Completions reasoning_content como el contrato principal actual
• Si solo te importa la respuesta final, Chat Completions con reasoning_effort sigue siendo adecuado
