Structured Output

When large models perform information extraction or structured data generation tasks, they often return extra text (such as `json markers), causing downstream parsing failures.

Solution​

Enable structured output by setting the response_format parameter to force the model to return a standard format pure JSON string.

Supported Models​

GLM

  • GLM-5.1
  • GLM-5
  • GLM-4.7

Minimax

  • MiniMax-M2.5
  • MiniMax-M2.1

Usage​

response_format: Specify response format, set to {"type": "json_object"} to enable JSON mode

Structured Output Examples​

Using in Python​

import requests

url = "https://api.jalapeno-cloud.ai/v1/chat/completions"

payload = {
    "model": "${MODEL_NAME}",
    "messages": [
        {
            "role": "system",
            "content": "Extract company full name, city, contact phone number as JSON. Keys: company_full_name, city, contact_phone. If info missing, set value to null."
        },
        {
            "role": "user",
            "content": "Global Cloud Solution Co., Ltd. is based in Singapore, no phone number provided."
        }
    ],
    "response_format": {
      "type": "json_object"
    }
}
headers = {
    "Authorization": "Bearer ${API_KEY}",
    "Content-Type": "application/json"
}

response = requests.request("POST", url, json=payload, headers=headers)

print(response.text)

Using in curl​

curl --location --request POST 'https://api.jalapeno-cloud.ai/v1/chat/completions' \
--header 'Authorization: Bearer ${API_KEY}' \
--header 'Content-Type: application/json' \
--data-raw '{
 "model": "${MODEL_NAME}",
 "messages": [
 {
 "role": "system",
 "content": "Extract company full name, city, contact phone number as JSON. Keys: company_full_name, city, contact_phone. If info missing, set value to null."
 },
 {
 "role": "user",
 "content": "Global Cloud Solution Co., Ltd. is based in Singapore, no phone number provided."
 }
 ],
 "response_format": {
 "type": "json_object"
 }
 }'

Response​

{
 "company_full_name": "Global Cloud Solution Co., Ltd.",
 "city": "Singapore",
 "contact_phone": null
}
