About ai prompts
What is an AI prompt?
An AI prompt is a single, carefully written instruction you send to a model to get one job done — the smallest, cheapest building block on Sigrix.
Every prompt on Sigrix is a ready-to-run instruction you own and can edit, with the model it was tested on and an example of the output it produces.
Compare prompts by the exact task they do, the model they were tested on, and price — then paste the one you pick straight into ChatGPT, Claude, or Gemini.
