How It Works

For pocket change per second.

01

Direct & Reference

Prompt + up to 9 references.

Start from a text prompt, an image, or a multi-asset brief: faces, environments, palettes, voice samples. One unified endpoint, /v1/happyhorse, accepts every combination of inputs.

Reference images lock identity and style. Voice references guide the dialogue. The model figures out the role of each asset.

Generate Sound + Vision

One forward pass. ~80 to 160 seconds on Segmind.

A unified single-stream Transformer denoises text, image, video, and audio tokens together. Eight DMD-2 steps, classifier-free guidance disabled.

1080p, 24 fps, multi-shot, dialogue and Foley aligned to the frame. No separate audio model, no post-production stitch.

Under the Hood

Built different.
Architecturally speaking.

Unified Token Sequence

Text, image, video, and audio tokens are jointly denoised in one Transformer. No separate audio model, no cross-attention. The model learns alignment, not stitching.

DMD-2 Distillation

Distribution Matching Distillation v2 cuts inference to 8 denoising steps and runs without classifier-free guidance. Far below the 25 to 50 steps typical for diffusion video.

Per-Head Modality Gates

Learned scalar gates dampen destructive cross-modal gradients during joint training, keeping the audio and video branches from competing for capacity. Reported in technical notes, not yet peer-reviewed.

Artificial Analysis Video Arena, blind preference Elo, late-April 2026 snapshot. Arena prompts skew toward portrait and dialogue content; long-action and reference-edit categories remain competitive across models. All per-second pricing reflects current Segmind list pricing for the named models with audio enabled where applicable. Seedance 2.0 uses token-based pricing; the listed per-second figure is a typical 5-second 1080p call ($1.21 average).

Frequently asked questions

What is HappyHorse 1.0?

HappyHorse 1.0 is Alibaba's video generation model. It creates 720p or 1080p clips of 3 to 15 seconds from a text prompt or a first-frame image, and generates dialogue, ambient sound and lip-synced speech in the same pass. On Segmind it runs through a pay-as-you-go API with no GPUs to manage.

How much does HappyHorse 1.0 cost on Segmind?

HappyHorse 1.0 costs $0.2002 per second at 720p and $0.3432 per second at 1080p on Segmind, with audio included at no extra charge. A 5-second clip costs about $1.00 at 720p and $1.72 at 1080p. There is no subscription or minimum spend: you pay per generation.

Which languages does HappyHorse 1.0 lip-sync?

HappyHorse 1.0 lip-syncs speech in seven languages: English, Mandarin, Cantonese, Japanese, Korean, German and French, aligning mouth movement at the phoneme level. You can also drive a clip with your own speech recording, an MP3 or WAV file of 3 to 30 seconds, through the audio_url input.

How long can a HappyHorse 1.0 video be?

A HappyHorse 1.0 clip runs 3 to 15 seconds per generation, and one clip can contain several shots. Iterate with 3 to 5 second clips at 720p, then render the final cut at 1080p. For longer stories, generate several clips and edit them together.

How does HappyHorse 1.0 compare with Seedance 2.0 and Kling 3.0 Pro?

HappyHorse 1.0 includes audio in its price: $0.3432 per second at 1080p on Segmind, close to Kling 3.0 Pro with audio at $0.336 per second, while Seedance 2.0 is billed per token. At launch in April 2026, HappyHorse 1.0 ranked first for text-to-video and image-to-video on the Artificial Analysis Video Arena.

How long does HappyHorse 1.0 take to generate a video?

HappyHorse 1.0 takes about 164 seconds per generation on Segmind, the 30-day average as of 13 October 2026. 720p renders finish faster than 1080p, so iterate on a prompt at 720p and switch to 1080p for the final render.

What is the difference between HappyHorse 1.0 and HappyHorse 1.1?

HappyHorse 1.1 is the successor to HappyHorse 1.0 from the same Alibaba lab. It adds reference-to-video with up to nine reference images and costs $0.2574 per second at 1080p, against $0.3432 for HappyHorse 1.0. HappyHorse 1.0 still accepts your own speech audio for lip-sync, which HappyHorse 1.1 does not.

How do I use HappyHorse 1.0 on Segmind?

Try HappyHorse 1.0 in the browser on its Segmind model page, or create an API key and send a POST request to https://api.segmind.cyou/v1/happyhorse with a prompt and the x-api-key header. HappyHorse 1.0 returns the finished MP4 in the response. Add an image for image-to-video or an audio_url for lip-sync.
