By skyforbes Go is simply the free version with 1) higher rate limits and 2) worse models. I'm not sure why, but comparing ChatGPT free in India vs. those of friends in US shows that the quality of the model are vastly different. The answers in US colleagues (for free) are much more comprehensive and more freely activates reasoning for same queries. Will provide sample queries later.
Given Go is higher rate limits, I was convinced to give it a shot but given the hallucinations and bad models, I never hit even close to the higher rate limits provided. So after being very disappointed by 1 month, I gave it another month to try to change my mind. Nothing changed. Poor quality models.
Now, why would OAI do this? My guess is that usage is flattening and they want more data for ads or model training. They're simply using our people as data fodder to help their ads business and beefen up their metrics for fundraising. I hope they make it int a better product but right now, it's honestly not even worth getting for free. I just feel dirty using ChatGPT at this point.
