h2oGPT

h2oGPT is a large language model (LLM) fine-tuning framework and chatbot UI with document(s) question-answer capabilities. Documents help to ground LLMs against hallucinations by providing them context relevant to the instruction. h2oGPT is fully permissive Apache V2 open-source project for 100% private and secure use of LLMs and document embeddings for document question-answer.

Welcome! Join us and make an issue or a PR, and contribute to making the best fine-tuned LLMs, chatbot UI, and document question-answer framework!

Supported OS and Hardware

GitHub license Linux macOS Windows Docker

GPU mode requires CUDA support via torch and transformers. A 6.9B (or 12GB) model in 8-bit uses 7GB (or 13GB) of GPU memory.

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.

Apache V2 ChatBot with LangChain Integration

  • LangChain equipped Chatbot integration and streaming responses
  • Persistent database using Chroma or in-memory with FAISS
  • Original content url links and scores to rank content against query
  • Private offline database of any documents (PDFs and more)
  • Upload documents via chatbot into shared space or only allow scratch space
  • Control data sources and the context provided to LLM
  • Efficient use of context using instruct-tuned LLMs (no need for many examples)
  • API for client-server control
  • CPU and GPU support from variety of HF models, and CPU support using GPT4ALL and LLaMa cpp
  • Linux, MAC, and Windows support

VectorDB

Apache V2 Data Preparation code, Training code, and Models

  • Variety of models (h2oGPT, WizardLM, Vicuna, OpenAssistant, etc.) supported
  • Fully Commercially Apache V2 code, data and models
  • High-Quality data cleaning of large open-source instruction datasets
  • LORA (low-rank approximation) efficient 8-bit and 16-bit fine-tuning and generation
  • Large (up to 65B parameters) models built on commodity or enterprise GPUs (single or multi node)
  • Evaluate performance using RLHF-based reward models

All open-source datasets and models are posted on 🤗 H2O.ai's Hugging Face page.

Also check out H2O LLM Studio for our no-code LLM fine-tuning framework!

General Roadmap items

  • 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

ChatBot and LangChain Roadmap items

  • Add other tools like search
  • Add agents for SQL and CSV question/answer

Getting Started

GPU (CUDA)

git clone https://github.com/h2oai/h2ogpt.git
cd h2ogpt
pip install -r requirements.txt
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6.9b --load_8bit=True

Then point browser at http://0.0.0.0:7860 (linux) or http://localhost:7860 (windows/mac) or the public live URL printed by the server (disable shared link with --share=False).

For quickly using a private document collection for Q/A, place documents (PDFs, text, etc.) into a folder called user_path and run

pip install -r requirements_optional_langchain.txt
python generate.py --base_model=h2oai/h2ogpt-oig-oasst1-512-6.9b  --load_8bit=True --langchain_mode=UserData --user_path=user_path

Any other instruct-tuned base models can be used, including non-h2oGPT ones. For more ways to ingest on CLI and contro see LangChain Readme

CPU

Follow instructions here: CPU. Then for LangChain support, put documents in user_path folder, and run:

python generate.py --base_model=gptj --score_model=None --langchain_mode=UserData --user_path=user_path

Larger models require more GPU memory

Depending on available GPU memory, you can load differently sized models. For multiple GPUs, automatic sharding can be enabled with --infer_devices=False, but this is disabled by default since cuda:x cuda:y mismatches can occur.

For GPUs with at least 24GB of memory, we recommend:

python generate.py --base_model=h2oai/h2ogpt-oasst1-512-12b --load_8bit=True

For GPUs with at least 48GB of memory, we recommend:

python generate.py --base_model=h2oai/h2ogpt-oasst1-512-20b --load_8bit=True

More information about the models can be found on H2O.ai's Hugging Face page.

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.
