@queencoyo Aria has to have limits per user or there is no way that it would be profitable for Opera (it costs you nothing to use, and it costs them a large server and a lot of money to provide). Aria uses the same AI models as many other places (GPT and Google PaLM to be specific). You can use GPT or Gemini (formerly known as Bard) instead, or a free unlimited AI like mine (https://best-codes.zapier.app/, it is coding themed, but I can change it if you'd like).
Gemini:

GPT (3.5 is free):

I hope this helps!
