Building applications with LLMs through composability.

This is the Java language implementation of LangChain.

Here's a simple example of using langchain-java to interact with OpenAI:

@Test
void testOpenAiCall() {
   OpenAI openAI = OpenAI.builder()
           .proxy(ProxyUtils.http("127.0.0.1", 1087))
           .maxTokens(10)
           .build()
           .init();

   assertThat(openAI.call("Say foo:")).isEqualTo("\n\nFoo!");
}

Prerequisites for building:

• Git
• Java 17
• Unix-like environment (we use Linux, Mac OS X)
• Maven (we recommend version 3.8.6 and require at least 3.5.4)

git clone https://github.com/HamaWhiteGG/langchain-java.git
cd langchain-java

# export JAVA_HOME=JDK17_INSTALL_DIR && mvn clean test
mvn clean test
