What does GPT-4 do?

GPT-4 is, at heart, a machine for?creating text. But it is a very good one, and to be very good at creating text turns out to be practically similar to being very good at understanding and reasoning about the world.

How much is GPT-4?

To use GPT-4, users have to subscribe to ChatGPT Plus, a $20 monthly subscription, for premium access to the service. GPT-4 currently has a cap of 100 messages every four hours.

Powerfull GPT

To put things into scale, the largest trained language model before?GPT-3?was Microsoft's Turing Natural Language Generation (NLG) model, which had 10 billion parameters. As of early 2021, GPT-3 is the largest neural network ever produced.

Model Size

According to Altman, GPT-4 won't be much bigger than GPT-3. So, we can assume that it will have around?175B-280B?parameters, similar to Deepmind's language model Gopher.

About GPT-4,

1. “GPT-4 has the same number of parameters as the number of neurons in the human brain, meaning that it will mimic our cognitive performance much more closely than GPT-3, because this model will have nearly as many neural connections as the human brain has,”
2. GPT-4 scores among the top 10% in a simulated US bar exam, whereas GPT-3.5 scores in the bottom 10%.?GPT-4 also outperforms GPT-3.5 on a range of writing, reasoning and coding tasks. The following examples illustrate how GPT-4 displays more reliable commonsense reasoning than GPT-3.5.
3. GPT-3.5 is limited to about 3,000-word responses, while GPT-4?can generate responses of more than 25,000 words.
4. GPT-4 is 82% less likely to respond to requests for disallowed content than its predecessor and scores 40% higher on certain tests of factuality.
