Vous pouvez voir $prompt 值。当我输入此提示值时，chat GPT 不会给出结果。但这是因为参数中的 "stream" => false 。如果 "stream" => true dans mon application ci-dessous, discuter avec GPT donne des résultats.

Ma question est de savoir pourquoi le chat GPT ne donne pas de résultats quand "stream" => false . Et que faire pour produire des résultats.
