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
  • 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
  • UI or CLI with streaming of all models
    • Upload and View documents via UI (control multiple collaborative or personal collections)
    • Bake-off UI mode against many models at same time
    • Easy Download of model artifacts and control over models like LLaMa.cpp via UI
    • Authentication in UI by user/password
    • State Preservation in UI by user/password
  • Linux, Docker, MAC, and Windows support
    • Easy Windows Installer for Windows 10 64-bit
  • Inference Servers support (HF TGI server, vLLM, Gradio, ExLLaMa, Replicate, OpenAI, Azure OpenAI)
  • OpenAI-compliant Python client API for client-server control
  • Evaluate performance using reward models
  • Quality maintained with over 300 unit and integration tests taking over 4 GPU-hours

Getting Started

GitHub license Linux macOS Windows Docker

To quickly try out h2oGPT on CPU with limited document Q/A capability using 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.

Windows 10/11 64-bit with full document Q/A capability

  • h2oGPT GPU-CUDA Installer (1.8GB file)
  • h2oGPT CPU Installer (755MB file) The installers include all dependencies for document Q/A, except models (LLM, embedding, reward) that are downloadable via UI. After installation, go to start and run h2oGPT, and a web browser will open for h2oGPT. To use LLaMa model, go to Models tab, select llama base model, then click load to download from preset URL. Then use as normal. To terminate the app, in task manager kill the Python process named pythonw.exe as will also show up in nvidia-smi if using GPUs. Set environment variables (in system properties->advanced->environment variables) to control things:
    • n_jobs: number of cores for various tasks
    • OMP_NUM_THREADS thread count for LLaMa
    • CUDA_VISIBLE_DEVICES which GPUs are visible
    • Any CLI argument from python generate.py --help with environment variable set as h2ogpt_x, e.g. h2ogpt_h2ocolors to False.
    • Set env h2ogpt_server_name to actual IP address for LAN to see app, e.g. h2ogpt_server_name to 192.168.1.172 and allow access through firewall if have Windows Defender activated.
  • Windows 10/11 Install and Run Docs

Linux (CPU/CUDA) with full document Q/A capability

MACOS (CPU/M1/M2) with full document Q/A capability

Example Models

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.

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:

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:

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.
