GPT 4 is here, but it is 15x more expensive than GPT 3.5 turbo, with 3.5 turbo being $0.002 / 1k tokens and GPT 4 being $0.002 / 1k tokens.

The advantage of GPT 4 currently is:

1. Increased responsiveness;

2. Image recognition;

3. Increased word limit from 3000 to 25000 (in request and response);

4. Improvement in 'steering', that is, that the chat assumes a better posture required by the user;

5. It has less 'hallucinations', that is, the system invents fewer stories and better obeys what is asked.

Problems:

1. It is slower;

2. It has a limit of 100 messages every 4 hours;

3. Filter even more what can be answered;

4. Biases: The system keeps going into certain political postures of the establishment and etc;

5. It is much more difficult to unlock the answers without limitations (jailbreak).

6. The amount of parameters is not what people expected, the 100 Tri compared to the 175 Bi of GPT 3, but it is believed to be approximately 1 Tri.
