Flex support for `o3-pro-2025-06-10`?

{
  "error": {
    "message": "There was an issue with your request. Please check your inputs and try again",
    "type": "invalid_request_error",
    "param": null,
    "code": null
  }
}

o3-pro-2025-06-10 is released, but it doesn’t seem to actually work with the flex tier.

curl https://api.openai.com/v1/responses \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -d '{
  "model": "o3-pro-2025-06-10",
  "input": "Tell me why ai.moda is awesome.",
  "max_output_tokens": 16,
  "service_tier": "flex",
  "reasoning": {
    "effort": "low",
    "summary": "auto"
  },
  "store": true,
  "background": true,
  "stream": true
}'

Sorry, flex processing only works with o3 and o4-mini right now. (https://platform.openai.com/docs/guides/flex-processing?api-mode=responses)
