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.)

  • 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

  • Chat and Text Completions (streaming and non-streaming)
  • Audio Transcription (STT)
  • Audio Generation (TTS)
  • Image Generation
  • Embedding
  • Function tool calling w/auto tool selection
  • AutoGen Code Execution Agent
• JSON Mode
  • Strict schema control for vLLM via its use of outlines
  • Strict schema control for OpenAI, Anthropic, Google Gemini, MistralAI models
  • JSON mode for some older OpenAI or Gemini models with schema control if model is smart enough (e.g. gemini 1.5 flash)
  • Any model via code block extraction
• Web-Search integration with Chat and Document Q/A
• Agents for Search, Document Q/A, Python Code, CSV frames
  • High quality Agents via OpenAI proxy server on separate port
  • Code-first agent that generates plots, researches, evaluates images via vision model, etc. (client code openai_server/openai_client.py).
  • No UI for this, just API
• Evaluate performance using reward models
• Quality maintained with over 1000 unit and integration tests taking over 24 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.

• Docker Build and Run Docs (Linux, Windows, MAC)
• Linux Install and Run Docs
• Windows 10/11 Installation Script
• MAC Install and Run Docs
• Quick Start on any Platform

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.

Acknowledgements

• Some training code was based upon March 24 version of Alpaca-LoRA.
• Used high-quality created data by OpenAssistant.
• Used base models by EleutherAI.
• Used OIG data created by LAION.

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.
