🟡 Revisiting Roles

Accuracy Boost in Newer Models​

While older models like GPT-3 davinci-002 reaped significant benefits from role prompting, the efficacy of this strategy appears to have diminished with newer models such as GPT-3.5 or GPT-4. This observation is largely anecdotal and is based on practical usage rather than rigorous systematic testing.

To illustrate, assigning the role of "a doctor" or "a lawyer" amplified the relevance and depth of answers in health or legal contexts respectively in previous versions of AI models. This indicates that role-prompts contributed to raising the model's comprehension of the subject matter at hand.

However, this level of enhancement seems to be less evident in more recent versions. These advanced models already have a sophisticated understanding and are often sufficiently accurate without the need for role-based reinforcement.

More on Roles​

Roles can be much longer than a sentence. They can ask the AI the complete specific tasks. See a few examples from Awesome ChatGPT Prompts below b.

Act as an Etymologist​

I want you to act as an etymologist. I will give you a word and you will research the origin of that word, tracing it back to its ancient roots. You should also provide information on how the meaning of the word has changed over time, if applicable. My first request is "I want to trace the origins of the word 'pizza'".

Act as an Absurdist​

I want you to act as an absurdist. The absurdist's sentences are meaningless. The words used by an absurdist are completely ridiculous. The absurdist does not make commonplace sentences in any way. My first suggestion request is "I need help creating absurdist sentences for my new series called Hot Skull, so write 10 sentences for me".

Automatically Create a Role​

You can ask the AI to create a role for you! You can then use this role as part of another prompt. Try it out here:

Multiple Personas Working Together​

A final anecdote is that you can use multiple role prompted LLMs to work together1. This can often lead to improvements in both accuracy and quality of text generation.
