Vous fournissez les ingr\u00e9dients (informations) et les \u00e9tapes \u00e0 suivre (directives) pour que l&rsquo;IA puisse pr\u00e9parer le plat (r\u00e9sultat). Imaginez que vous demandiez \u00e0 un chef de pr\u00e9parer une pizza.  Votre instruction pourrait \u00eatre\u00a0: \u00ab\u00a0Pr\u00e9parez une pizza Margherita avec une p\u00e2te fine et croustillante, de la sauce tomate San Marzano, de la mozzarella fra\u00eeche et du basilic frais.\u00a0\u00bb L&rsquo;IA, comme le chef, suit ces instructions pour produire le r\u00e9sultat souhait\u00e9.<\/p>\n<h3>Pourquoi l&rsquo;instruction est-elle importante\u00a0?<\/h3>\n<p>L&rsquo;instruction est essentielle car elle guide le comportement de l&rsquo;IA.  Une instruction claire et pr\u00e9cise permet d&rsquo;obtenir des r\u00e9sultats pertinents et coh\u00e9rents.  \u00c0 l&rsquo;inverse, une instruction vague ou ambigu\u00eb peut conduire \u00e0 des r\u00e9sultats inattendus ou insatisfaisants. En prompt engineering, la qualit\u00e9 de l&rsquo;instruction est cruciale pour optimiser les performances de l&rsquo;IA et obtenir les meilleurs r\u00e9sultats possibles. Par exemple, si vous souhaitez qu&rsquo;une IA g\u00e9n\u00e8re une image, une instruction pr\u00e9cise comme \u00ab\u00a0Un chat roux assis sur un fauteuil bleu\u00a0\u00bb donnera un r\u00e9sultat plus pr\u00e9cis qu&rsquo;une instruction vague telle que \u00ab\u00a0Un animal\u00a0\u00bb.<\/p>\n<h3>Exemples d&rsquo;utilisation d&rsquo;une instruction<\/h3>\n<p>Voici quelques exemples d&rsquo;instructions que vous pourriez donner \u00e0 une IA\u00a0:<br \/>\n* <strong>G\u00e9n\u00e9ration de texte\u00a0:<\/strong> \u00ab\u00a0\u00c9crivez un po\u00e8me sur le th\u00e8me de l&rsquo;automne.\u00a0\u00bb<br \/>\n* <strong>Traduction\u00a0:<\/strong> \u00ab\u00a0Traduisez cette phrase en anglais.\u00a0\u00bb<br \/>\n* <strong>Classification\u00a0:<\/strong> \u00ab\u00a0Classez ces images par cat\u00e9gorie.\u00a0\u00bb<br \/>\n* <strong>R\u00e9sum\u00e9\u00a0:<\/strong> \u00ab\u00a0R\u00e9sumez cet article en 100\u00a0mots.\u00a0\u00bb<\/p>\n<h3>Termes associ\u00e9s<\/h3>\n<ul id=\"TermesAssocies\">\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Prompt\">Prompt<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Param%C3%A8tres\">Param\u00e8tres<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Requ%C3%AAte\">Requ\u00eate<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Entr%C3%A9e\">Entr\u00e9e<\/a><\/li>\n<li><a href=\"https:\/\/happynumeric.com\/lexique-intelligence-artificielle\/?s=Sortie\">Sortie<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>En intelligence artificielle et en prompt engineering, l&rsquo;instruction est un \u00e9l\u00e9ment fondamental.
