ChatGPT

Yes, certain versions of ChatGPT, such as those utilizing GPT-4, can browse the internet to provide up-to-date information. However, the base models rely entirely on their pre-existing training data. This makes the Plus tier much more useful for current events and research.

The token limit depends on the specific model you are using, with GPT-4 Turbo offering a context window of 128,000 tokens. This equates to roughly the length of a 300-page book, allowing for very long conversations and document uploads. Older models like GPT-3.5 have significantly lower limits, typically around 4,096 tokens.

ChatGPT was created by the artificial intelligence research laboratory OpenAI and launched in November 2022. It was built upon the GPT-3.5 large language model at launch, later upgrading to GPT-4 for premium users. The release quickly sparked widespread interest in generative AI technologies.

By default, ChatGPT saves your chat history so you can resume conversations later, which also allows OpenAI to use this data to train future models. If you are concerned about privacy, you can disable chat history in the settings menu. For enterprise users, OpenAI provides plans that do not use your data for training purposes.
