This is an experimental tree-based writing interface for GPT-3. The code is actively being developed and thus unstable and poorly documented.

Features

• Read mode

  • Linear story view
  • Tree nav bar
  • Edit mode

• Tree view

  • Explore tree visually with mouse
  • Expand and collapse nodes
  • Change tree topology
  • Edit nodes in place

• Navigation

  • Hotkeys
  • Bookmarks
  • Chapters
  • 'Visited' state

• Generation

  • Generate N children with GPT-3
  • Modify generation settings
  • Change hidden memory on a node-by-node basis

• File I/O

  • Open/save trees as JSON files
  • Work with trees in multiple tabs
  • Combine trees

Demo

ooo what features! wow so cool

Block multiverse mode

Read this for a conceptual explanation of block multiverse interface and demo video

How to use in loom

1. Click Wavefunction button on bottom bar. This will open the block multiverse interface in the right sidebar (drag to resize).
2. Write initial prompt in the main textbox.
3. [Optional] Write ground truth continuation in the gray entry box at the bottom of the block multiverse interface. Blocks in ground truth trajectory will be colored black.
4. Set model and params in top bar.
5. Click Propagate to propagate plot the block multiverse
6. Click on any of the blocks to zoom ("renormalize") to that block
7. Click Propagate again to plot future block multiverse starting from a renormalized frame
8. Click Reset zoom to reset zoom level to initial position
9. Click Clear to clear the block multiverse plot. Do this before generating a new block multiverse.

Instructions

Linux

0. Make sure you have tkinter installed

   sudo apt-get install python3-tk

1. Setup your python env (should be >= 3.9.13)

    ```python3 -m venv env```
    ```source env/bin/activate```
   

2. Install requirements

   pip install -r requirements.txt

3. [Optional] Set environmental variables for OPENAI_API_KEY, GOOSEAI_API_KEY, AI21_API_KEY (you can also use the settings options)

   export OPENAI_API_KEY={your api key}

4. Run main.py

5. Load a json tree

6. Read :)

Mac

1. conda create -n pyloom python=3.10
2. conda activate pyloom
3. pip install -r requirements-mac.txt
4. set the OPENAI_API_KEY env variable
5. python main.py

Docker

(Only tested on Linux.)

0. [Optional] Edit the Makefile with your API keys (you can also use the settings options)

1. Run the make targets

    ```make build```
    ```make run```
   

2. Load a json tree

3. Read :)

Local Inference with llama-cpp-python

llama.cpp lets you run models locally, and is especially useful for running models on Mac. [https://github.com/abetlen/llama-cpp-python] provides nice installation and a convenient API.

Setup

1. conda create -n llama-cpp-local python=3.10; conda activate llama-cpp-local
2. Set your preferred backend before installing llama-cpp-python, as per these instructions. For instance, to infer on MPS: CMAKE_ARGS="-DLLAMA_METAL=on"
3. pip install 'llama-cpp-python[server]'
4. pip install huggingface-hub
5. Now you can run the server with whatever .gguf model you desire from Huggingface, i.e: python3 -m llama_cpp.server --hf_model_repo_id NousResearch/Meta-Llama-3-8B-GGUF --model 'Meta-Llama-3-8B-Q4_5_M.gguf' --port 8009

Inference

1. conda activate llama-cpp-local and start your llama-cpp-python server.
2. In a new terminal window, activate your pyloom environment and run main.py
3. Enter configurations for your local model in Settings > Model config > Add model. By default, the llama-cpp-port-8009 model uses the following settings:

{
            'model': 'Meta-Llama-3-8B-Q4_5_M',
            'type': 'llama-cpp',
            'api_base': 'http://localhost:8009/v1',
},
