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 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
• 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.)
• UI or CLI with streaming of all models
  • Upload and View documents through the 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 through the UI
  • Authentication in the UI by user/password
  • State Preservation in the UI by user/password
• Linux, Docker, macOS, 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
• 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

Getting Started

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
python generate.py --base_model='llama' --prompt_type=llama2 --model_path_llama=https://huggingface.co/TheBloke/Llama-2-7B-Chat-GGML/resolve/main/llama-2-7b-chat.ggmlv3.q8_0.bin --max_seq_len=4096

then go to your browser by visiting http://127.0.0.1:7860 or http://localhost:7860. Choose 13B for a better model than 7B. If you encounter issues with llama-cpp-python or other packages that try to compile and fail, try binary wheels for your platform as linked in the detailed instructions below.

We recommend quantized (e.g. GGML) models for most small-GPU systems, e.g. LLaMa-2-7B-Chat-GGML for 9GB+ GPU memory or larger models like LLaMa-2-13B-Chat-GGML if you have 16GB+ GPU memory.

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

• One-click Installers Oct 06, 2023:

  • h2oGPT GPU-CUDA Installer (1.8GB file)
  • h2oGPT CPU Installer (755MB file)

  Aug 19, 2023:

  • h2oGPT GPU-CUDA Installer (1.8GB file)
  • h2oGPT CPU Installer (755MB file)

  The installers include all dependencies for document Q/A except for models (LLM, embedding, reward), which you can download through the 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 used. Recommend set to single fast GPU, e.g. CUDA_VISIBLE_DEVICES=0 if have multiple GPUs. Note that UI cannot control which GPUs (or CPU mode) for LLaMa models.
  • 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.

Example Models

• Highest accuracy and speed on 16-bit with TGI/vLLM using ~48GB/GPU when in use (4xA100 high concurrency, 2xA100 for low concurrency)
• Middle-range accuracy on 16-bit with TGI/vLLM using ~45GB/GPU when in use (2xA100)
• Small memory profile with ok accuracy 16GB GPU if full GPU offloading
• Balanced accuracy and size on 16-bit with TGI/vLLM using ~45GB/GPU when in use (1xA100)
• Smallest or CPU friendly 32GB system ram or 9GB GPU if full GPU offloading
• Best for 4*A10G using g5.12xlarge AWQ LLaMa 70B using 4*A10G using vLLM GPU mode requires CUDA support via torch and transformers. A 7B/13B model in 16-bit uses 14GB/26GB of GPU memory to store the weights (2 bytes per weight). Compression such as 4-bit precision (bitsandbytes, AWQ, GPTQ, etc.) can further reduce memory requirements down to less than 6GB when asking a question about your documents. (For more information, see low-memory mode.)

CPU mode uses GPT4ALL and LLaMa.cpp, e.g. gpt4all-j, requiring about 14GB of system RAM in typical use.

Experimental features

These are not part of normal installation instructions and are experimental.

• SerpAPI web search augmentation -- in Beta testing. Working well but hits file closed failure under intense use.
• Agents -- in Alpha testing. Optimal for OpenAI, but that also fails sometimes.

Roadmap

• Integration of code and resulting LLMs with downstream applications and low/no-code platforms
• Complement h2oGPT chatbot with other APIs like ToolBench
• Enhance the model's code completion, reasoning, and mathematical capabilities, ensure factual correctness, minimize hallucinations, and avoid repetitive output
• Add better 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.
