How does increasing the temperature parameter during text generation affect the output of ChatGPT?

Increasing the temperature parameter during text generation makes the output of ChatGPT more random and creative. The temperature parameter is a setting that controls the probability distribution of the words the model can choose from at each step. A higher temperature makes the probability distribution flatter, meaning that less likely words have a higher chance of being selected. This encourages the model to explore a wider range of possibilities and generate more diverse and unexpected text. Conversely, a lower temperature makes the probability distribution sharper, emphasizing the most likely words and resulting in more predictable and conservative output. For instance, with a low temperature, the model might consistently generate very similar sentences. However, with a higher temperature, the model is more likely to generate novel or surprising phrases, even if they are less grammatically correct or contextually relevant. While higher temperatures can increase creativity, they also increase the risk of generating nonsensical or incoherent text. The temperature value must therefore be tuned carefully, depending on the desired balance between creativity and accuracy.
