OpenAI Dall·E

note

This is the documentation for the OpenAI integration, that uses a custom Java implementation of the OpenAI REST API, that works best with Quarkus (as it uses the Quarkus REST client) and Spring (as it uses Spring's RestClient).

LangChain4j provides 3 different integrations with OpenAI for generating images, and this is #1 :

  • OpenAI uses a custom Java implementation of the OpenAI REST API, that works best with Quarkus (as it uses the Quarkus REST client) and Spring (as it uses Spring's RestClient).

  • OpenAI Official SDK uses the official OpenAI Java SDK.

  • Azure OpenAI uses the Azure SDK from Microsoft, and works best if you are using the Microsoft Java stack, including advanced Azure authentication mechanisms.
