Mistral AI大 2 (24.07) 参数和推理

Mistral AI聊天完成API功能允许您创建对话应用程序。您也可以在此型号上使用 Amazon Bedrock Conver API se。您可以使用工具进行函数调用。

提示

您可以将Mistral AI聊天完成功能API与基本推理操作（InvokeModel或 InvokeModelWithResponseStream）一起使用。但是，我们建议您使用 Convers API e 在应用程序中实现消息。Converse API 提供了一组统一的参数，适用于所有支持消息的模型。有关更多信息，请参阅 与匡威进行对话。

Mistral AI模型在 Apache 2.0 许可下可用。有关使用Mistral AI模型的更多信息，请参阅Mistral AI文档。
