## Cotas e limites
<a name="model-card-amazon-nova-2-lite-quotas"></a>

Sua AWS conta tem cotas padrão para manter o desempenho do serviço e garantir o uso adequado do Amazon Bedrock. As cotas padrão atribuídas a uma conta podem ser atualizadas dependendo de fatores regionais, histórico de pagamentos, uso fraudulento e and/or aprovação de uma solicitação de aumento de cota[. ](bedrock/latest/userguide/quotas-increase.html) Para obter mais informações, consulte a [Cotas do Amazon Bedrock](quotas.md) documentação e [ os ](general/latest/gr/bedrock.html#limits_bedrock) limites do modelo.

## Código de exemplo
<a name="model-card-amazon-nova-2-lite-sample-code"></a>

**Etapa 1 - AWS Conta: ** Se você já tem uma AWS conta, pule esta etapa. Se você não conhece AWS, cadastre-se em uma conta [ da AWS](https://portal.aws.amazon.com/billing/signup).

**Etapa 2 - Chave de API: ** acesse o console do [ Amazon Bedrock ](https://console.aws.amazon.com/bedrock/home#/api-keys/long-term/create) e gere uma chave de API de longo prazo.

**Etapa 3 - Obtenha o SDK: ** para usar este guia de introdução, você deve ter o Python já instalado. Em seguida, instale o software relevante, dependendo das APIs que você está usando.

```
pip install boto3
```

**Etapa 4 - Definir variáveis de ambiente: ** configure seu ambiente para usar a chave de API para autenticação.

```
AWS_BEARER_TOKEN_BEDROCK="<provide your Bedrock API key>"
```

**Etapa 5 - Execute sua primeira solicitação de inferência: ** salve o arquivo como `bedrock-first-request.py`
