h2oGPT

Turn ★ into ⭐ (top-right corner) if you like the project!

Query and summarize your documents or just chat with local private GPT LLMs using h2oGPT, an Apache V2 open-source project.

Private offline database of any documents (PDFs, Excel, Word, Images, Code, Text, MarkDown, etc.)
Persistent database (Chroma, Weaviate, or in-memory FAISS) using accurate embeddings (instructor-large, all-MiniLM-L6-v2, etc.)
Efficient use of context using instruct-tuned LLMs (no need for LangChain's few-shot approach)
Parallel summarization reaching 80 tokens/second output 13B LLaMa2
Upload and View documents via UI (control multiple collaborative or scratch collections)
UI or CLI with streaming of all models
Bake-off UI mode against many models at same time
Variety of models supported (LLaMa2, Falcon, Vicuna, WizardLM including AutoGPTQ, 4-bit/8-bit, LORA)
GPU support from HF and LLaMa.cpp GGML models, and CPU support using HF, LLaMa.cpp, and GPT4ALL models
Linux, Docker, MAC, and Windows support
Inference Servers support (HF TGI server, vLLM, Gradio, ExLLaMa, OpenAI)
OpenAI-compliant Python client API for client-server control
Evaluate performance using reward models
Quality maintained with over 250 unit and integration tests taking over 4 GPU-hours

Getting Started

To quickly try out h2oGPT with LLaMa2 7B Chat, create a fresh Python 3.10 environment and run:

git clone https://github.com/h2oai/h2ogpt.git
cd h2ogpt
pip install -r requirements.txt
pip install -r reqs_optional/requirements_optional_langchain.txt
pip install -r reqs_optional/requirements_optional_gpt4all.txt
# if don't have wget, copy the below link to browser and download and place file into h2ogpt folder
wget https://huggingface.co/TheBloke/Llama-2-7B-Chat-GGML/resolve/main/llama-2-7b-chat.ggmlv3.q8_0.bin
python generate.py --base_model='llama' --prompt_type=llama2

then go to your browser by visiting http://127.0.0.1:7860 or http://localhost:7860.

Supported OS and Hardware

GPU mode requires CUDA support via torch and transformers. A 6.9B (or 12GB) model in 8-bit uses 8GB (or 13GB) of GPU memory. 8-bit precision, 4-bit precision, and AutoGPTQ can further reduce memory requirements down no more than about 6.5GB when asking a question about your documents (see low-memory mode).

CPU mode uses GPT4ALL and LLaMa.cpp, e.g. gpt4all-j, requiring about 14GB of system RAM in typical use.

GPU and CPU mode tested on variety of NVIDIA GPUs in Ubuntu 18-22, but any modern Linux variant should work. MACOS support tested on Macbook Pro running Monterey v12.3.1 using CPU mode, as well as MAC M1 using MPS.

Roadmap

Integration of code and resulting LLMs with downstream applications and low/no-code platforms
Complement h2oGPT chatbot with search and other APIs
High-performance distributed training of larger models on trillion tokens
Enhance the model's code completion, reasoning, and mathematical capabilities, ensure factual correctness, minimize hallucinations, and avoid repetitive output
Add other tools like search
Add agents for SQL and CSV question/answer

Development

To create a development environment for training and generation, follow the installation instructions.
To fine-tune any LLM models on your data, follow the fine-tuning instructions.

To run h2oGPT tests:

wget https://huggingface.co/TheBloke/Llama-2-7B-Chat-GGML/resolve/main/llama-2-7b-chat.ggmlv3.q8_0.bin
pip install requirements-parser pytest-instafail
pytest --instafail -s -v tests
# for client tests
make -C client setup
make -C client build
pytest --instafail -s -v client/tests

or tweak/run tests/test4gpus.sh to run tests in parallel.

Why H2O.ai?

Our Makers at H2O.ai have built several world-class Machine Learning, Deep Learning and AI platforms:

#1 open-source machine learning platform for the enterprise H2O-3
The world's best AutoML (Automatic Machine Learning) with H2O Driverless AI
No-Code Deep Learning with H2O Hydrogen Torch
Document Processing with Deep Learning in Document AI

We also built platforms for deployment and monitoring, and for data wrangling and governance:

H2O MLOps to deploy and monitor models at scale
H2O Feature Store in collaboration with AT&T
Open-source Low-Code AI App Development Frameworks Wave and Nitro
Open-source Python datatable (the engine for H2O Driverless AI feature engineering)

Many of our customers are creating models and deploying them enterprise-wide and at scale in the H2O AI Cloud:

Multi-Cloud or on Premises
Managed Cloud (SaaS)
Hybrid Cloud
AI Appstore

We are proud to have over 25 (of the world's 280) Kaggle Grandmasters call H2O home, including three Kaggle Grandmasters who have made it to world #1.
