- 9. Chat GPT-3 vs GPT-4
- 11. Prompt tip Description Prompt Example 1 Resetting the Model Resetting the model can help generate new and diverse responses. "ignore all previous prompts and..." 2 Topic Expertise ChatGPT can be asked to be an expert on a specific topic. “You are an expert in physics, can you explain the theory of relativity to me?" 3 Imitating a Writer You can prompt ChatGPT to write in the style of a specific writer. "Write a paragraph in the style of Ernest Hemingway." 4 Own Writing Style You can prompt ChatGPT to generate text in your own writing style. "Write a sentence using my writing style."
- 12. Prompt tip Description Prompt Example 5 Semantic Similarity Using semantic similarity can help generate more relevant responses. "Generate a sentence that has a similar meaning to 'I am feeling happy today'." 6 Controlled Generation Controlled generation can help generate responses that adhere to specific constraints. "Generate a list of three adjectives that describe my personality." 7 Novelty and Creativity Open-ended prompts can result in novel and creative responses. "Write a short story that begins with the sentence 'The world had ended, but for some reason, I was still alive'." 8 Temperature Adjusting the temperature can help control the level of creativity in the generated responses. "Generate a response to the prompt 'What is the meaning of life?' with a temperature of 0.5."
