Les SDK OpenAI et Anthropic relancent généralement les requêtes en cas d’erreur réseau ou de réponse 5xx. Pour les générations, désactivez ce comportement (max_retries=0) et vérifiez X-Should-Retry avant toute nouvelle tentative. Une réponse perdue ne signifie pas que la requête n’a pas été exécutée.
