# Stability AI models
<a name="model-parameters-stability-diffusion"></a>

This section describes the request parameters and response fields for Stability AI models. Use this information to make inference calls to Stability AI models with the [InvokeModel](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_runtime_InvokeModel.html) operation. This section also includes Python code examples that shows how to call Stability AI 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](models-supported.md). Some models also work with the [Converse API](conversation-inference.md). To check if the Converse API supports a specific Stability AI model, see [models at a glance](model-cards.md). For more code examples, see [Code examples for Amazon Bedrock using AWS SDKs](service_code_examples.md).

Foundation models in Amazon Bedrock support input and output modalities, which vary from model to model. To check the modalities that Stability AI models support, see [Supported foundation models in Amazon Bedrock](models-supported.md). To check which Amazon Bedrock features the Stability AI models support, see [Supported foundation models in Amazon Bedrock](models-supported.md). To check which AWS Regions that Stability AI models are available in, see [Supported foundation models in Amazon Bedrock](models-supported.md).

When you make inference calls with Stability AI 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](prompt-engineering-guidelines.md). For Stability AI specific prompt information, see the [Stability AI prompt engineering guide](https://platform.stability.ai/docs/getting-started).

## Supported models and image services
<a name="supported-stability-models"></a>

Amazon Bedrock supports the following Stability AI models and image services.

**Note**  
Support for all other Stability AI models are in the process of being deprecated.
