Translation by ChatGPT

Hi, I'm using Smart Book with my own OpenAI API key and the default model gpt-5-nano. When I try to translate a paragraph, the API returns: Unsupported value: 'reasoning_effort' does not support 'none' with this model. Supported values are: 'minimal', 'low', 'medium', and 'high'. Could you please check whether Smart Book explicitly sets reasoning_effort to none? GPT-5-nano supports minimal, low, medium and high, but not none. It would be great if this parameter could be changed in the settings or automatically set to minimal for GPT-5 models. Thank you!
