LangChain¶

Installation¶

    implementation("org.http4k:http4k-connect-ai-langchain")
}

LangChain4J is a versatile library that simplifies the creation and management of language processing workflows., It provides many integrations but does not allow for using http4k clients or http4k-connect clients. This module gives you some of these integrations by providing LangChain model adapters.

Current adapters support http4k client integrations for the following models, allowing you to use them in your http4k applications:

OpenAI
OpenAiChatLanguageModel
OpenAiChatImageModel
OpenAiChatEmbeddingModel
Ollama
OllamaChatLanguageModel
OllamaChatImageModel
OllamaChatEmbeddingModel
S3 Document Loaders

Using these adapters is as simple as:

val model: ChatLanguageModel = OpenAiChatLanguageModel(OpenAI.Http(OpenAIToken.of("hello"), FakeOpenAI()))
val chat: Response<AiMessage> = model.generate("hello kitty")
