Amazon Titan models

This section describes the request parameters and response fields for Amazon Titan models. Use this information to make inference calls to Amazon Titan models with the InvokeModel and InvokeModelWithResponseStream (streaming) operations. This section also includes Python code examples that shows how to call Amazon Titan models. To use a model in an inference operation, you need the model ID for the model. To get the model ID, see Supported foundation models in Amazon Bedrock. Some models also work with the Converse API. To check if the Converse API supports a specific Amazon Titan model, see Supported models and model features. For more code examples, see Code examples for Amazon Bedrock using AWS SDKs.

Foundation models in Amazon Bedrock support input and output modalities, which vary from model to model. To check the modalities that Amazon Titan models support, see Supported foundation models in Amazon Bedrock. To check which Amazon Bedrock features the Amazon Titan models support, see Supported foundation models in Amazon Bedrock. To check which AWS Regions that Amazon Titan models are available in, see Supported foundation models in Amazon Bedrock.

When you make inference calls with Amazon Titan models, you include a prompt for the model. For general information about creating prompts for the models that Amazon Bedrock supports, see Prompt engineering concepts.
