How to Use Happy Horse 1.0
Steps to get you started in Wireflow.
Enter Your Prompt
Type a text description of the video you want into the Text Input node. The workflow on this page is text-to-video.
Configure Output Settings
Set resolution, clip duration, and aspect ratio on the video node. Happy Horse 1.0 is not available on Wireflow yet, so that node runs Gemini Omni Flash 1.1.
Generate and Export Your Video
Run the workflow to produce your video. Review the output on the canvas, adjust prompts if needed, and export in your preferred format.
Generate Video and Audio with Happy Horse 1.0
Happy Horse 1.0 is a 15-billion-parameter unified Transformer that generates both video and synchronized audio in a single forward pass. It supports text-to-video and image-to-video inputs at native 1080p resolution, producing clips with dialogue, ambient sound, and Foley effects. Wireflow does not run Happy Horse 1.0 yet. The workflow on this page sends your prompt to Gemini Omni Flash 1.1 instead, which you can chain with other models and post-processing on the visual canvas.
The model ranked #1 globally on the Artificial Analysis Video Arena in both text-to-video (Elo 1333) and image-to-video (Elo 1392) categories under blind user voting. It supports lip-sync in six languages: English, Chinese, Japanese, Korean, German, and French. As a fully open-source release with commercial-use rights, it can be self-hosted, fine-tuned, and deployed on your own enterprise infrastructure.

What one Gemini Omni Flash 1.1 clip costs on Wireflow
Happy Horse 1.0 is not on Wireflow yet, so the workflow on this page runs Gemini Omni Flash 1.1. Wireflow bills each run in credits. Starter is $36 a month for 2,660 credits, and Professional is $59 a month for 4,370 credits.
- One 5 second Gemini Omni Flash 1.1 clip uses 80 credits, $1.08 on Starter or Professional. That is about 33 clips a month on Starter and about 54 on Professional.
Shorter clips can cost a bit more per second; you're always charged for the real length.
Run the workflow from Claude
You can also run this video workflow from a Claude chat. Add Wireflow as a connector once:
- In Claude, open Customize, then Connectors. Click + Add and choose Add custom connector.
- Name it Wireflow and paste
https://www.wireflow.ai/api/mcpas the server URL. - Sign in to Wireflow when Claude asks, and approve the access.
The Claude app setup guide has the full steps. Then ask in plain words, for example:
Example prompt: "Use Wireflow to make a 5 second Gemini Omni Flash 1.1 clip of a horse galloping along a beach at sunrise. Tell me the credit cost and wait for my yes before you run it."
With that last line, Claude looks up the price and waits for your yes before it spends any credits. Runs use the credits on your Wireflow account.
