Frequently Asked Questions
Can GPT Image 2 generate videos?
No. GPT Image 2 is OpenAI's text-to-image model; it only outputs still images. To get video, pipe GPT Image 2 outputs into an image-to-video model like HappyHorse 1.0.
What is the best workflow — GPT Image 2 + HappyHorse?
Generate your image in ChatGPT with GPT Image 2, download it, then upload to HappyHorse for image-to-video. HappyHorse animates it at native 1080p in about 10 seconds.

Yes — HappyHorse 1.0 is fully open source with a commercial license. You can use this hosted site's free tier, or self-host at zero marginal cost.
Will HappyHorse preserve GPT Image 2's character consistency?
Yes. Image-to-video mode uses your GPT Image 2 still as the first frame, so character, style and composition are preserved through the generated clip.
Why not just wait for OpenAI to add native video to GPT Image 2?
OpenAI's current video model is Sora, which scores 1190 on image-to-video (vs HappyHorse's 1392), is 6x slower, and is closed source. For the highest-quality, fastest, fully open alternative, HappyHorse is already the better pipeline today.
