Overview

LinGoose is a powerful Go framework for developing Large Language Model (LLM) based applications using pipelines. It is designed to be a complete solution and provides multiple components, including Prompts, Templates, Chat, Output Decoders, LLM, Pipelines, and Memory. With LinGoose, you can interact with LLM AI through prompts and generate complex templates. Additionally, it includes a chat feature, allowing you to create chatbots. The Output Decoders component enables you to extract specific information from the output of the LLM, while the LLM interface allows you to send prompts to various AI, such as the ones provided by OpenAI. You can chain multiple LLM steps together using Pipelines and store the output of each step in Memory for later retrieval. LinGoose also includes a Document component, which is used to store text, and a Loader component, which is used to load Documents from various sources. Finally, it includes TextSplitters, which are used to split text or Documents into multiple parts, Embedders, which are used to embed text or Documents into embeddings, and Indexes, which are used to store embeddings and documents and to perform searches.

Components

LinGoose is composed of multiple components, each one with its own purpose.

Component	Package	Description
Prompt	prompt	Prompts are the way to interact with LLM AI. They can be simple text, or more complex templates. Supports Prompt Templates and Whisper prompt
Chat Prompt	chat	Chat is the way to interact with the chat LLM AI. It can be a simple text prompt, or a more complex chatbot.
Decoders	decoder	Output decoders are used to decode the output of the LLM. They can be used to extract specific information from the output. Supports JSONDecoder and RegExDecoder
LLMs	llm	LLM is an interface to various AI such as the ones provided by OpenAI. It is responsible for sending the prompt to the AI and retrieving the output. Supports OpenAI, HuggingFace and Llama.cpp.
Pipelines	pipeline	Pipelines are used to chain multiple LLM steps together.
Memory	memory	Memory is used to store the output of each step. It can be used to retrieve the output of a previous step. Supports memory in Ram
Document	document	Document is used to store a text
Loaders	loader	Loaders are used to load Documents from various sources. Supports TextLoader, DirectoryLoader, PDFToTextLoader and PubMedLoader .
TextSplitters	textsplitter	TextSplitters are used to split text or Documents into multiple parts. Supports RecursiveTextSplitter.
Embedders	embedder	Embedders are used to embed text or Documents into embeddings. Supports OpenAI
Indexes	index	Indexes are used to store embeddings and documents and to perform searches. Supports SimpleVectorIndex, Pinecone and Qdrant

Usage

Please refer to the documentation at lingoose.io to understand how to use LinGoose. If you prefer the 👉 examples directory contains a lot of examples 🚀. However, here is a powerful example of what LinGoose is capable of:

Talk is cheap. Show me the code. - Linus Torvalds

package main

import (
	"context"

	openaiembedder "github.com/henomis/lingoose/embedder/openai"
	"github.com/henomis/lingoose/index"
	"github.com/henomis/lingoose/index/option"
	"github.com/henomis/lingoose/index/vectordb/jsondb"
	"github.com/henomis/lingoose/llm/openai"
	"github.com/henomis/lingoose/loader"
	qapipeline "github.com/henomis/lingoose/pipeline/qa"
	"github.com/henomis/lingoose/textsplitter"
)

func main() {
	docs, _ := loader.NewPDFToTextLoader("./kb").WithTextSplitter(textsplitter.NewRecursiveCharacterTextSplitter(2000, 200)).Load(context.Background())
	index := index.New(jsondb.New().WithPersist("db.json"), openaiembedder.New(openaiembedder.AdaEmbeddingV2)).WithIncludeContents(true)
	index.LoadFromDocuments(context.Background(), docs)
	qapipeline.New(openai.NewChat().WithVerbose(true)).WithIndex(index).Query(context.Background(), "What is the NATO purpose?", option.WithTopK(1))
}

This is the famous 4-lines lingoose knowledge base chatbot. 🤖
