Der ChatGPT Prompting Leitfaden

Der Leitfaden soll den Prozess der Erstellung von effektiven Prompts veranschaulichen. Diese Prompts können für die Erstellung von Texten, z.B. mit ChatGPT, formuliert werden. Die Qualität der Prompts ist ein entscheidender Faktor für die Genauigkeit und das Potenzial der Ergebnisse. Darüber hinaus findet sich im unteren Bereich ein "Cheat Sheet" mit den gängigsten Erklärungen in knapper Form in englischer Sprache, da die LLMs besser in ihrer Entwicklungssprache sind.
