I have a plus account, and in “model” select box a have selected GPT 4. But if i ask it what model this is - it will say to me that it is 3.5 GPT and knows nothing about GPT 4. I know that some people with plus do have access to gpt4. And i know that openAI promised to give all users some amount of messages to send to gpt4. I do not really understand, how can i talk to gpt4? I paid only for it, and why i not getting what i paid for? O maybe i don’t really understand something?
