Features

Private offline database of any documents (PDFs, Excel, Word, Images, Video Frames, YouTube, Audio, 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 and extraction, reaching an output of 80 tokens per second with the 13B LLaMa2 model
- HYDE (Hypothetical Document Embeddings) for enhanced retrieval based upon LLM responses
- Semantic Chunking for better document splitting (requires GPU)
Variety of models supported (LLaMa2, Mistral, Falcon, Vicuna, WizardLM. With AutoGPTQ, 4-bit/8-bit, LORA, etc.)
- GPU support from HF and LLaMa.cpp GGML models, and CPU support using HF, LLaMa.cpp, and GPT4ALL models
- Attention Sinks for arbitrarily long generation (LLaMa-2, Mistral, MPT, Pythia, Falcon, etc.)
Gradio UI or CLI with streaming of all models
- Upload and View documents through the UI (control multiple collaborative or personal collections)
- Vision Models LLaVa, Claude-3, Gemini-Pro-Vision, GPT-4-Vision
- Image Generation Stable Diffusion (sdxl-turbo, sdxl, SD3) and PlaygroundAI (playv2)
- Voice STT using Whisper with streaming audio conversion
- Voice TTS using MIT-Licensed Microsoft Speech T5 with multiple voices and Streaming audio conversion
- Voice TTS using MPL2-Licensed TTS including Voice Cloning and Streaming audio conversion
- AI Assistant Voice Control Mode for hands-free control of h2oGPT chat
- Bake-off UI mode against many models at the same time
- Easy Download of model artifacts and control over models like LLaMa.cpp through the UI
- Authentication in the UI by user/password via Native or Google OAuth
- State Preservation in the UI by user/password
Open Web UI with h2oGPT as backend via OpenAI Proxy
- Supports chat completion with streaming, vision models, document Q/A, STT, TTS, image generation, authentication, and state preservation. See Start-up Docs.
Linux, Docker, macOS, and Windows support
Inference Servers support for oLLaMa, HF TGI server, vLLM, Gradio, ExLLaMa, Replicate, Together.ai, OpenAI, Azure OpenAI, Anthropic, MistralAI, Google, and Groq
OpenAI-compliant
- Server Proxy API (h2oGPT acts as drop-in-replacement to OpenAI server)
- Supports Chat and Text Completions (streaming and non-streaming), Audio Transcription (STT), Audio Generation (TTS), Image Generation, and Embedding
JSON Mode with any model via code block extraction. Also supports MistralAI JSON mode, Claude-3 via function calling with strict Schema, OpenAI via JSON mode, and vLLM via guided_json with strict Schema
Web-Search integration with Chat and Document Q/A
Agents for Search, Document Q/A, Python Code, CSV frames (Experimental, best with OpenAI currently)
Evaluate performance using reward models
Quality maintained with over 1000 unit and integration tests taking over 4 GPU-hours

Get Started

Install h2oGPT

Docker is recommended for Linux, Windows, and MAC for full capabilities. Linux Script also has full capability, while Windows and MAC scripts have less capabilities than using Docker.

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:

pip install requirements-parser pytest-instafail pytest-random-order playsound==1.3.0
conda install -c conda-forge gst-python -y
sudo apt-get install gstreamer-1.0
pip install pygame
GPT_H2O_AI=0 CONCURRENCY_COUNT=1 pytest --instafail -s -v tests
# for openai server test on already-running local server
pytest -s -v -n 4 openai_server/test_openai_server.py::test_openai_client

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.
