## Überblick
OpenAI Codex ist ein leistungsfähiges KI-System, das natürliche Sprache in Code übersetzt und in der Lage ist, Code in Dutzenden von Programmiersprachen zu verstehen und zu generieren. Basierend auf der GPT-3-Architektur und trainiert auf Milliarden von Zeilen öffentlichen Codes, unterstützt Codex GitHub Copilot und bietet fortschrittliche Funktionen zur Code-Vervollständigung, -Generierung und -Erklärung. Es glänzt durch das Verstehen von Kontext, das Generieren von Funktionen, Klassen und ganzen Anwendungen aus natürlichsprachlichen Beschreibungen.
> ⚠️ **Hinweis**: Die OpenAI Codex API wurde im März 2023 eingestellt. Dieser Leitfaden behandelt historische Nutzung und Migration zu GPT-3.5/GPT-4 Modellen für Code-Generierungsaufgaben.
