No data leaves your device and 100% private. You can use LocalGPT to ask questions to your documents without an internet connection, using the power of large language models (LLMs).

LocalGPT is built with LangChain and Vicuna-7B, which are open-source frameworks for building NLP applications. It also uses InstructorEmbeddings, which are embeddings that can guide the LLMs to generate relevant responses. LocalGPT can handle various file types, such as .txt, .pdf, .csv,and can index and search across multiple documents.

Why Create a Personal AI Assistant with LocalGPT?

pip install -r requirements.txt

If you want to use GPU acceleration for faster inference, you will need CUDA 11 or higher installed on your device. You will also need to set some flags for llama-cpp, which is a library that LocalGPT uses for indexing and searching. You can do this by running CMAKE_ARGS=”-DLLAMA_CUBLAS=on” FORCE_CMAKE=1 pip install -r requirements.txt.

Alternatively, you can use Docker to install and run LocalGPT. You will need Docker, BuildKit, your Nvidia GPU driver, and the Nvidia container toolkit installed on your device.

How to Ingest Documents into LocalGPT?

Put all your documents that you want to chat with into the SOURCE_DOCUMENTS directory in the LocalGPT repository. You can use any of the supported file types, such as .txt, .pdf, .csv, or .xlsx. If you want to use other file types, you will need to convert them to one of the supported file types first.

Run the script with python This will process all the documents in the SOURCE_DOCUMENTS directory and create an index file called index.llama in the localGPTUI directory. This index file will store all the information about your documents, such as their names, contents, embeddings, etc.

Optionally, you can also specify some arguments for the script, such as the device type (-device_type), the batch size (-batch_size), the number of workers (-num_workers), and the verbosity level (-verbosity). For example, if you want to use CPU instead of GPU for ingesting documents, you can run python -device_type cpu.

How to Chat with Your Documents Using LocalGPT?

Run the following command to start the LocalGPT API python This will launch a graphical user interface (GUI) that allows you to interact with LocalGPT. You will receive a link at the bottom of the page. Open up a web browser and go the address http://localhost:5111/.

Type your question or query in the input box at the bottom of the chat window and press search. LocalGPT will use the LLM and the InstructorEmbeddings to generate a response based on the document’s content and context. You will see the response in the chat window, along with some metadata, such as the response time and perplexity score.
