Allow us to use GPT-4o mini without wasting the rate limits of GPT-4o

Hello, I have the free version of ChatGPT. In some scenarios, I want to use GPT-4o mini without wasting the rate limits of GPT-4o, but the website forces me to use GPT-4o first. This results in wasted rate limits, which GPT-4o mini could have easily answered my question sent to ChatGPT without needing GPT-4o.

Please let us use GPT-4o mini without wasting our rate limits of GPT-4o.
