Since it went out chat gpt is being vastly used and tested for fun and for businesses. It’s been estimated that it costs OpenAI around $100k a day to run Chat GPT. So it’s definitely a possibility OpenAI will develop a paid plan FOR Chat GPT, just like they did for DALL-E. The question is how much will it cost and what features will pro version bring.
It’s reported it should cost $42/ month, and it will give unlimited access, especially useful in periods when the demand is high and when you can’t get to use it.
