Ao contrário do ajuste fino, a engenharia de prompt orienta o comportamento de um modelo sem alterar os pesos do modelo. Graças aos fortes recursos de base dos modelos de fundação, muitas pessoas os adaptaram com sucesso para aplicações usando apenas a engenharia de prompt. Você deve aproveitar ao máximo o prompt antes de passar para técnicas que consomem mais recursos, como o ajuste fino.
A facilidade de uso do prompt engineering pode fazer com que as pessoas pensem que não há muito a ser feito.1 À primeira vista, a engenharia de prompt parece que você está apenas mexendo nas palavras até que algo funcione. Embora o prompt engineering envolva, de fato, muita manipulação, ele também envolve muitos desafios interessantes e soluções engenhosas. Você pode pensar na engenharia de prompt como uma comunicação entre humanos e IA: você se comunica com modelos de IA para que eles façam o que você quer. Qualquer um pode se comunicar, mas nem todos podem se comunicar de forma eficaz. Da mesma forma, é fácil escrever prompts, mas não é fácil construir prompts eficazes.
Algumas pessoas argumentam que a "engenharia de prompt" não tem ...
