What is the real reason behind OpenAI launching Instant-access ChatGPT?

Although OpenAI officially states that it has opened ChatGPT without registration to allow more users to access artificial intelligence, there are still many discussions among users.

Others think that OpenAI is attempting to acquire more user data to train models and save operational costs.

But whatever the reason, for the average person, OpenAI's adjustment this time has lowered the barrier for using ChatGPT. For similar AI products, there may be some user attrition, and it may also push them to introduce similar features. From the perspective of consumers, these are undoubtedly a great benefit.
