Azure OpenAI Image Models
Azure OpenAI provides image generation models that can create or modify images based on natural language prompts. These models enable use cases such as visual storytelling, creative content generation, and image editing workflows.
For an overview of how image models fit into AI workflows, refer to the Image Models section of the Models documentation.
Prerequisites
Azure OpenAI Account and API Key
To use Azure OpenAI models in your Quarkus application, configure your Azure credentials and endpoint.
-
Obtain your Azure OpenAI endpoint, resource name, deployment name, and either an api-key or an Azure AD access token from the Azure Portal.
-
Configure your application.properties with the necessary details:
quarkus.langchain4j.azure-openai.resource-name=
quarkus.langchain4j.azure-openai.deployment-name=
# And one of the below depending on your scenario
quarkus.langchain4j.azure-openai.api-key=
quarkus.langchain4j.azure-openai.ad-token=Azure OpenAI Quarkus Extension
To use Azure OpenAI image models in your Quarkus application, add the following extension:
<dependency>
<groupId>io.quarkiverse.langchain4j</groupId>
<artifactId>quarkus-langchain4j-azure-openai</artifactId>
<version>1.0.2</version>
</dependency>If no other LLM extension is installed, AI Services will automatically use the configured Azure OpenAI image model.
|
This extension also supports Azure OpenAI chat and embedding models. Moderation models are not currently supported by Azure OpenAI. |

What sampling temperature to use, with values between 0 and 2. Higher values means the model will take more risks.

Environment variable: |
double |
|

You can configure multiple Azure OpenAI image models using named configurations:
# Default image model configuration
quarkus.langchain4j.azure-openai.image-model.model-name=dall-e-3
#Named configuration
quarkus.langchain4j.azure-openai.my-image.image-model.model-name=dall-e-2Use the modelName attribute in the @RegisterAiService annotation to specify which model to use in your AI service. When using the programmatic API, you can also use the @ModelName annotation to select a specific model:
import io.quarkiverse.langchain4j.ModelName;
import dev.langchain4j.model.image.ImageModel;
import jakarta.inject.Inject;
@Inject ImageModel defaultImageModel;
@Inject @ModelName("my-image") ImageModel namedImageModel;
