Trying to use the supplied GPT-5 mini, which is shown to be free from Zapier (meaning we don’t have to connect our own OpenAI account), using the AI by Zapier tool. I have entered input fields, knowledge sources, prompts and output fields, and when I go to generate preview I’m met with the following error message: Invalid model_id: openai/gpt-5-mini

I would like to use this model to execute my prompt, and I am on a paid Zapier plan which does include AI usage.
