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!

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. 4-bit precision can further reduce memory requirements.
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.
- 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
- 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 4-bit, 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

- 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
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_4bit=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_4bit=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 control see LangChain Readme
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
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
or
python generate.py --base_model=h2oai/h2ogpt-oasst1-512-20b --load_4bit=True
For GPUs with at least 48GB of memory, we recommend:
python generate.py --base_model=h2oai/h2ogpt-oasst1-512-20b --load_8bit=True
etc.
More information about the models can be found on H2O.ai's Hugging Face page.
