Embeds Koog with other frameworks, featuring Spring AI integration through a specialized client utilizing Spring AI's ChatClient. Supports prompt execution and response handling using Koog's DSL.
Surfaced from shared tags and platforms — no rankings paid for.
Koog-sauce is a missing ingredient that connects Koog with other frameworks.
SpringAiLLMClient, which uses Spring AI's ChatClient under the hood.Langchain4jLLMClient for seamless integration with , supporting both standard and streaming interactions.Add the dependency to your build.gradle.kts file:

The project includes comprehensive tests for both Spring AI and LangChain4j integrations:
SpringOpenAiTest demonstrates how to use and test the Spring AI integration with OpenAI models.Langchain4jLLMClientTest tests the standard LangChain4j LLM client functionality.StreamingLangchain4jLLMClientTest tests the streaming capabilities of the LangChain4j LLM client.These tests serve as additional examples of how to use the integrations in your own projects.
