Compare and test open-weight models for text, code, voice and vision, no sign-up required. Then move to production with the same OpenAI-compatible API.
gpt-oss-20b delivers strong performance with fast inference and efficient reasoning. Ideal for a wide range of tasks, it offers flexible deployment for developers seeking powerful, customizable AI solutions.
First install the requests library:
pip install requestsNext, export your access token to the OVH_AI_ENDPOINTS_ACCESS_TOKEN environment variable:
export OVH_AI_ENDPOINTS_ACCESS_TOKEN=<your-access-token>If you do not have an access token key yet, follow the instructions in the AI Endpoints – Getting Started.
Finally, run the following Python code:
import os
import requests
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {os.getenv('OVH_AI_ENDPOINTS_ACCESS_TOKEN')}",
}
# With /chat/completions

"messages": [
{
"content": "Explain gravity to a 6 years old",
"role": "user"
}
],
"model": "gpt-oss-20b",
"temperature": 0,
}
response = requests.post(url, json=payload, headers=headers)
if response.status_code == 200:
# Handle response
response_data = response.json()
# Parse JSON response
choices = response_data["choices"]
for choice in choices:
text = choice["message"]["content"]
# Process text and finish_reason
print(text)
reasoning_text = choice["message"]["reasoning_content"]
# Process reasoning_content
print(reasoning_text)
else:
print("Error:", response.status_code, response.text)

print(f"** CONTENT ** \n {text_content}\n")
else:
print("Error:", response.status_code, response.text)The gpt-oss-20b API is compatible with the OpenAI specification.
First install the openai library:
pip install openaiNext, export your access token to the OVH_AI_ENDPOINTS_ACCESS_TOKEN environment variable:
export OVH_AI_ENDPOINTS_ACCESS_TOKEN=<your-access-token>Finally, run the following Python code:
import os
from openai import OpenAI
url = "https://oai.endpoints.kepler.ai.cloud.ovh.net/v1"
client = OpenAI(
base_url=url,
api_key=os.getenv("OVH_AI_ENDPOINTS_ACCESS_TOKEN")
)

).choices.pop()
print(f"** REASONING ** \n {choice.message.reasoning_content}\n")
