Learn PromptingWeighted Terms
Some models (Stable Diffusion, Midjourney, etc.) allow you to weight terms in a prompt. This can be used to emphasize certain words or phrases in the generated image. It can also be used to de-emphasize certain words or phrases in the generated image. Let's consider a simple example:
Example
Here are a few mountains generated by Stable Diffusion, with the prompt mountain.
However, if we want mountains without trees, we can use the prompt mountain | tree:-10. Since we weighted tree very negatively, they do not appear in the generated image.
Weighted terms can be combined into more complicated prompts, like
A planet in space:10 | bursting with color red, blue, and purple:4 | aliens:-10 | 4K, high quality

Sander Schulhoff is the CEO of HackAPrompt and Learn Prompting. He created the first Prompt Engineering guide on the internet, two months before ChatGPT was released, which has taught 3 million people how to prompt ChatGPT. He also partnered with OpenAI to run the first AI Red Teaming competition, HackAPrompt, which was 2x larger than the White House's subsequent AI Red Teaming competition. Today, HackAPrompt partners with the Frontier AI labs to produce research that makes their models more secure. Sander's background is in Natural Language Processing and deep reinforcement learning. He recently led the team behind The Prompt Report, the most comprehensive study of prompt engineering ever done. This 76-page survey, co-authored with OpenAI, Microsoft, Google, Princeton, Stanford, and other leading institutions, analyzed 1,500+ academic papers and covered 200+ prompting techniques.
