Overview
This module adds support for selected Google Gemini models.
Maven Coordinates
In addition to the Helidon integration with LangChain4j core dependencies, you must add the following:
<dependency>
<groupId>io.helidon.integrations.langchain4j.providers</groupId>
<artifactId>helidon-integrations-langchain4j-providers-google-gemini</artifactId>
</dependency>content_copy
Components
GoogleAiGeminiChatModel
To automatically create and add GoogleAiGeminiChatModel to the service registry add the following lines to application.yaml:
langchain4j:
providers:
google-gemini:
api-key: "${GEMINI_TOKEN}"
models:
gemini-chat-model:
provider: google-gemini
model-name: "gemini-2.0-flash"content_copy
If enabled is set to false, the configuration is ignored, and the component is not created.
