Open AI has a freemium model whereby GPT-3.5 is free and GPT-4 (“Plus”) is not. Understandably, there are questions about whether GPT-4 is worth the cost. Is it better? How much better?
One simple answer is: GPT-4 is 8% better.
Why? The perceived quality of the response. Putting other features and benefits aside, responses are the main product of AI platforms, and how users perceive differences among them is a key factor in evaluating their value and price.
