I want to start using ChatGPT, but I don't know where the best place to look for it is. Which platforms are reliable and what to look for when choosing? Is there a difference in versions or access on different sites?

Chat GPT can be found on the official OpenAI website, as well as in applications and platforms that use its API. When choosing, it is worth paying attention to the officiality of the resource to avoid fake sites and data leaks. Also check what version of Chat GPT is offered and whether there are restrictions on use. Check out one of such services at this link
