The frequency of use of GPT is gradually decreasing

Our team is an agnet application development team. After more than a year, we have developed many applications to assist the company’s office work, which has greatly saved the company’s costs. But recently when chatting with brother companies, I found that brother companies are also abandoning the use of GPT and gradually reducing the use of GPT. I want to know why this is. Are there too many large AI model companies? Or is it because the GPT api is too expensive? Our team believes that the ChatGPT project is a good project.
Developers please speak freely. Talk about your views on the openai team’s ChatGPT project. This will help our entrepreneurship and artificial intelligence development to make more contributions to mankind.
Thanks!
