OmniHuman 1.5 vs Happy Horse 1.1
Neither one is cheaper across the board, and the split falls on resolution rather than on length. Across the 2 renders both models price, OmniHuman 1.5 costs less at 1080p and Happy Horse 1.1 costs less at 720p. 15s at 720p is 490 credits on OmniHuman 1.5 against 420 on Happy Horse 1.1, while 15s at 1080p is 490 credits on OmniHuman 1.5 against 550 on Happy Horse 1.1. Pick by the resolution you actually deliver in and the cheaper model follows from it. In practice, take OmniHuman 1.5 if you need one continuous clip longer than 15 seconds, and Happy Horse 1.1 if the cut has to land on an exact length for a placement.
We run OmniHuman 1.5 (ByteDance) and Happy Horse 1.1 (Alibaba) ourselves, on our own provider accounts, inside the same studio and off the same credit balance. Everything below is read out of the catalogue that prices your renders, so the numbers are the ones your account is actually charged. What you will not find here is a quality verdict: we hold no benchmark that would make one honest, so every claim on this page is a capability or a price you can check.
OmniHuman 1.5 vs Happy Horse 1.1: the specs
Every cell below is read from the catalogue that our generator and our billing run on, so it is what you get and what you are charged, not what a vendor page advertises. Two rows are worth reading carefully: where the render runsis the platform we actually dispatch to, which is not always the one a model’s Replicate name implies, and how the length is set separates the models you give a duration to from the ones whose clip runs as long as the speech does.

Like for like: what the same render costs
Only the clip lengths and resolutions BOTH models price appear here. Comparing a 5 second render against a 15 second one and calling the gap a price difference is the most common way these comparisons go wrong, so rows that do not line up exactly are left out.
| Render | OmniHuman 1.5 | Happy Horse 1.1 | Difference |
|---|---|---|---|
| 15s at 720p | 490 credits | 420 credits | 70 credits cheaper on Happy Horse 1.1 |
| 15s at 1080p | 490 credits | 550 credits | 60 credits cheaper on OmniHuman 1.5 |
Credit costs, not dollars: what a credit costs you depends on the plan, and all three plans are listed on the pricing page.
Which one to pick
Each line below traces back to a single difference in the tables above. Where a model has no measurable advantage, that is what it says.
Pick OmniHuman 1.5 if
- You need one continuous clip longer than 15 secondsOmniHuman 1.5 runs to 30s in a single call. Happy Horse 1.1 caps at 15s, so anything longer has to be cut together from more than one render.
- The script is the fixed thing and the length can follow itOmniHuman 1.5 runs for as long as the speech takes rather than to a duration you pick, so a long script does not have to be cut into 15s pieces. It runs to 30s in one call.
- You deliver at 1080pOmniHuman 1.5 is cheaper on 1 of the 2 like-for-like renders, the one at 1080p.
- You deliver at 1080p and are buying seconds rather than a clip lengthAt 1080p OmniHuman 1.5 works out at 32.7 credits a second against 36 for Happy Horse 1.1. At 720p it goes the other way.
Pick Happy Horse 1.1 if
- The cut has to land on an exact length for a placementHappy Horse 1.1 takes the duration as an input, so a 6 second slot is a 6 second render. OmniHuman 1.5 has no duration setting at all: its length is set by the voice track, so you write to fit the slot instead of picking it.
- One shot has to combine several things you already have, a product, a face, a backgroundHappy Horse 1.1 carries up to 9 reference images into a single render. OmniHuman 1.5 carries one, so the rest has to come from the prompt.
- You want to see it on your own product before you pay anythingHappy Horse 1.1 runs during the free 3-day trial. OmniHuman 1.5 is on paid plans only, so trying it means starting a plan first.
- You deliver at 720pHappy Horse 1.1 is cheaper on 1 of the 2 like-for-like renders, the one at 720p.
- You want the cheapest possible render to test an idea onHappy Horse 1.1 starts at 140 credits (5s at 720p). The cheapest row OmniHuman 1.5 prices is 490 credits (15s at 720p), and it has no duration setting: its charge follows the script's spoken length at 32.7 credits a second, so a shorter script costs less than that row.
- You deliver at 720p and are buying seconds rather than a clip lengthAt 720p Happy Horse 1.1 works out at 28 credits a second against 32.7 for OmniHuman 1.5. At 1080p it goes the other way.
What they have in common
A comparison that manufactures a difference is worse than no comparison, so here is where OmniHuman 1.5 and Happy Horse 1.1 genuinely match.
- Both need a reference image. Neither will render from a prompt on its own, and the input carries one image on OmniHuman 1.5 and up to 9 images on Happy Horse 1.1.
- Both price 720p and 1080p.
- Neither has an announced end date.
- Both are dispatched to Replicate from our own account, OmniHuman 1.5 as bytedance/omni-human-1.5 and Happy Horse 1.1 as alibaba/happyhorse-1.1.
- Both spend from that one balance on every plan, so moving a campaign from OmniHuman 1.5 (from 490 credits a render) to Happy Horse 1.1 (from 140) costs you nothing but the credit difference.

One credit balance, every model
OmniHuman 1.5 and Happy Horse 1.1both spend from the same balance, so a plan is not a commitment to one of them. Here is what each plan’s credits buy on the two models on this page, measured in seconds of finished video.
| Plan | Credits a month | OmniHuman 1.5 | Happy Horse 1.1 |
|---|---|---|---|
| Starter $49 a month, or $34 billed annually | 5,000 | 152 seconds | 135 to 178 seconds |
| Growth $99 a month, or $69 billed annually | 12,000 | 366 seconds | 324 to 428 seconds |
| Agency $199 a month, or $139 billed annually | 25,000 | 764 seconds | 675 to 892 seconds |
The low end of each range is the model’s dearest priced tier and the high end its cheapest, both from the tables above, so a month spent entirely at 1080p sits at the bottom and a month of 720p drafts near the top. Mixing models moves it in between. On a paid plan, credits are the only limit: no cap on how many renders you make and no per-model licence. Annual billing is 30% off (Starter saves $180 a year, Agency $720). Happy Horse 1.1 runs during the free 3-day trial. OmniHuman 1.5 needs a paid plan.
OmniHuman 1.5 vs Happy Horse 1.1: frequently asked questions
Which is cheaper, OmniHuman 1.5 or Happy Horse 1.1?
Neither one is cheaper across the board, and the split falls on resolution rather than on length. Across the 2 renders both models price, OmniHuman 1.5 costs less at 1080p and Happy Horse 1.1 costs less at 720p. 15s at 720p is 490 credits on OmniHuman 1.5 against 420 on Happy Horse 1.1, while 15s at 1080p is 490 credits on OmniHuman 1.5 against 550 on Happy Horse 1.1. Pick by the resolution you actually deliver in and the cheaper model follows from it.
How long can a single OmniHuman 1.5 or Happy Horse 1.1 clip be?
OmniHuman 1.5 caps at 30s and prices 15s and 30s. Happy Horse 1.1 caps at 15s and prices 5s, 10s and 15s. Both are per-render limits, so a longer ad is several renders cut together rather than one long generation.
What resolutions do OmniHuman 1.5 and Happy Horse 1.1 render at?
OmniHuman 1.5 is priced at 720p and 1080p, priced identically because the request we send is the same either way, so the tier is a label rather than a setting that reaches the model. Happy Horse 1.1 is priced at 720p and 1080p. Those are the tiers you can actually buy, not the tiers the vendors advertise.
How many reference images can OmniHuman 1.5 and Happy Horse 1.1 take?
Happy Horse 1.1 carries up to 9 reference images into one render and OmniHuman 1.5 carries one. That matters when a shot has to combine things you already have, a product, a hand, a background, in the same frame: with one image the rest has to be described in the prompt and re-rolled until it lands. The counts are read from the request each model is actually sent, not from a vendor spec sheet.
Do OmniHuman 1.5 and Happy Horse 1.1 need a reference image?
Both do. Neither OmniHuman 1.5 nor Happy Horse 1.1 will render from a text prompt alone, so you need a product shot or an avatar frame first.
How do OmniHuman 1.5 and Happy Horse 1.1 handle audio?
Differently, and it changes how you brief them. OmniHuman 1.5 is driven by a voice track instead: we generate that track from your script before the render starts, and the clip runs as long as the speech does. Happy Horse 1.1 generates its audio in the same pass as the picture, so there is no separate voice step to run or pay for. That is the difference between choosing a length and writing to one: Happy Horse 1.1 takes the duration as an input, while OmniHuman 1.5 runs for as long as the words take.
Do I need a separate plan for each model?
No. Every plan is one credit balance that spends on any model we run, so the same subscription renders an OmniHuman 1.5 test at 490 credits and a Happy Horse 1.1 test at 140 and you compare them on your own footage. There is no per-model licence, and on a paid plan credits are the only thing that runs out rather than a render count.
Can I try OmniHuman 1.5 and Happy Horse 1.1 on the free trial?
One of them. Happy Horse 1.1 runs during the free 3-day trial, from 140 credits a render against a 250 credit per-render ceiling. OmniHuman 1.5 is not available on the trial and needs a paid plan. We would rather say so on this page than have the product refuse after you have signed up.
Where do these OmniHuman 1.5 and Happy Horse 1.1 numbers come from?
From the accounts the renders actually run on. OmniHuman 1.5 is dispatched to Replicate as bytedance/omni-human-1.5 and Happy Horse 1.1 to Replicate as alibaba/happyhorse-1.1, both ours. The 4 priced tiers listed for OmniHuman 1.5 and the 6 priced tiers for Happy Horse 1.1 are read at build time from the same price table that debits your balance when a render finishes, and the capabilities come from the record the generator reads to build each request, so a reprice or a new tier rewrites this page instead of leaving a stale number on it. What you will not find is a quality or realism score for either one: we hold no benchmark that would make one honest.
