# AI use cases for Helix World (NoizAI/HelixWorld)

Repo: [NoizAI/HelixWorld](https://github.com/NoizAI/HelixWorld) | Use cases: 3 | Page: https://dedupedai.com/use-cases/noizai-helixworld/

HelixWorld is a Python research repo for a real-time interactive audio-visual world model that generates video and camera-aligned spatial sound from a starting image, a prompt, and movement or camera actions.

This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL.

## How to render a first-person walkthrough MP4 from one image with Helix World

Repo: [NoizAI/HelixWorld](https://github.com/NoizAI/HelixWorld) | Difficulty: Advanced | Time: 2 hours | Basis: From the README

Run the Preview v1 pipeline on a first-frame image to get a clean MP4 with motion-driven video and sound.

**Who it is for:** A creative developer or researcher with a 80 GB NVIDIA GPU who wants a short interactive-style clip generated from a single still image and a movement script.

**The problem:** Turning one still image into a moving first-person scene with matching sound usually means stitching video and audio tools by hand, and the audio often does not follow the camera.

**The outcome:** An MP4 in the output directory showing the scene moving through the requested action sequence, with audio generated alongside the picture.

### Steps

1. `git clone https://github.com/NoizAI/HelixWorld.git`
2. `cd HelixWorld`
3. `conda create -n helixworld-preview python=3.11 -y`
4. `conda activate helixworld-preview`
5. `python -m pip install -r requirements.txt` then `python download_models.py`
6. `CUDA_VISIBLE_DEVICES=0 ./run.sh --image /path/to/first_frame.png --prompt-file examples/prompt.json --actions "W:5,right:5,stop:5" --perspective first_person --num-frames 121 --output-dir outputs/demo` (inferred, check the README)

### Prompt to paste into your agent

```text
In the HelixWorld repo (NoizAI/HelixWorld), set up the Preview v1 environment as described in the README, then run ./run.sh with --image <path to first-frame PNG> and --output-dir outputs/demo. Expect a clean MP4 under outputs/demo, and verify that the file exists and that ffprobe reports a video stream and an audio stream.
```

### Caveat

The README recommends 80 GB of VRAM and a BF16 run uses about 70 GB, so smaller GPUs may fail; download size is not stated in the README.

## How to score whether generated sound follows camera motion with Helix World

Repo: [NoizAI/HelixWorld](https://github.com/NoizAI/HelixWorld) | Difficulty: Advanced | Time: 4 hours | Basis: From the README

Use the HelixBench dataset to test if synthesized sound fields track dynamic viewpoint motion.

**Who it is for:** A research engineer comparing audio-visual world models who needs a shared test set for spatial-acoustic consistency.

**The problem:** Teams building interactive audio-visual models have no shared way to check whether sound changes correctly when the viewpoint moves.

**The outcome:** A local copy of the HelixBench dataset and a documented evaluation pass that checks sound fields against viewpoint motion in your own model outputs.

### Steps

1. Open https://huggingface.co/datasets/NoizAI/Helixbench and read the dataset card for file layout and license.
2. Download the dataset files from the Hugging Face page into a local folder. (inferred, check the README)
3. Run Helix World on the same first frames and action inputs listed in the dataset, using the command pattern in the Preview v1 section of the README.
4. Compare each generated clip's stereo panning against the camera motion in the matching dataset item. (inferred, check the README)
5. Record the per-clip results in a table so your model and Helix World can be compared on the same items.

### Prompt to paste into your agent

```text
Using the NoizAI/Helixbench dataset on Hugging Face and the HelixWorld repo (NoizAI/HelixWorld), generate outputs for the dataset items into <output folder> and compare stereo panning with camera motion for each clip. Expect a results table with one row per clip; verify that the row count matches the number of dataset items.
```

### Caveat

The README does not describe the HelixBench file format or metrics, so the comparison steps must be checked against the dataset card before use.

## How to walk through a Helix World scene in the browser with Helix World

Repo: [NoizAI/HelixWorld](https://github.com/NoizAI/HelixWorld) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README

Open the hosted demo to hear how sound changes as you move and turn, with no local setup.

**Who it is for:** A product manager, designer, or curious viewer who wants to judge the audio-visual experience before investing in a local GPU setup.

**The problem:** Reading about camera-synced audio does not show whether it works, and local inference needs a large GPU.

**The outcome:** A short hands-on impression of how picture and sound update together during movement and turns.

### Steps

1. Open https://helixworld.org/ in a desktop browser.
2. Pick a scene and move forward or turn around.
3. Listen for whether the sound shifts with your viewpoint and note any lag between picture and audio.
4. Compare what you heard with the README claim that audio is not a soundtrack laid on afterwards.

### Prompt to paste into your agent

```text
Open https://helixworld.org/ in a browser, move forward and turn in one scene from the HelixWorld project (NoizAI/HelixWorld), and report whether the sound changes with the viewpoint. Expect a short written note; verify that the note states the scene name and the observed sound changes.
```

### Caveat

The README only says you can roam a world in the browser, so the hosted demo's controls and availability may change.
