A interface web do Claude ([claude.ai](https://claude.ai)) e os aplicativos móveis usam um "system prompt" (prompt do sistema) para fornecer informações atualizadas, como a data atual, ao Claude no início de cada conversa. O prompt do sistema também incentiva certos comportamentos, como sempre fornecer trechos de código em Markdown. Esse prompt é atualizado periodicamente para melhorar as respostas do Claude. Essas atualizações do prompt do sistema não se aplicam à Claude API. Alguns modelos têm várias entradas datadas em suas páginas.
