Same Model, Different App: Choosing Where to Generate Video

You want Kling or Veo for a batch of shorts. You can get it from the model maker's own app, from its API, or from a dozen creator apps that bundle it next to twenty other models. Same model name, very different price per second, different limits, different watermark and different rights. Picking the wrong one can double your monthly bill or leave you with clips you are not allowed to use in an ad.

This guide shows how to compare the places that sell the same model, and when each one makes sense.

Three ways to buy the same model

Every popular generative model reaches you through some mix of three channels:

1. The maker's own app. Google sells Veo and Nano Banana through Gemini and Google Flow. Kuaishou sells Kling through the Kling AI app. Runway sells its Gen-4.5 in Runway. ByteDance ships Seedance and Seedream in CapCut and Dreamina.
2. The maker's API, billed per second of video or per image. Google's Gemini API, Black Forest Labs' API for FLUX, the Kling API, MiniMax's API.
3. Aggregators: creator apps that resell many makers' models inside one credit system. Higgsfield, Krea, Magnific (formerly Freepik), Leonardo.Ai, OpenArt, Luma's app, invideo AI and Adobe Firefly (as partner models) all do this.

The model map shows which apps offer which model. It is the fastest way to see your options; for example, Veo is listed in about thirty apps in our directory, Kling in close to thirty, and Runway's Gen-4.5 in only about ten.

Why the same model costs different amounts

Aggregators do not all pay the same wholesale price, and they do not pass it on the same way. Three things change the price you see:

• Credit conversion. Each app sells credits at its own price and charges its own number of credits per clip. Higher tiers usually make each credit cheaper.
• Model variant. "Veo 3.1" can mean Lite, Fast or Standard (Google also calls the top one Quality in Flow). The API price between Lite and Standard differs by a factor of five or more. An app that just says "Veo 3.1" may be running any of them.
• Bundled extras. Some plans include "unlimited" or relaxed generations on selected, usually older or in-house, models. That is great value if the included model is the one you want, and irrelevant if not.

Here is a snapshot from plan and pricing pages at the time of writing. Treat it as a method, not a price list.

Two lessons jump out. First, the same maker's model can be several times cheaper on its API than in an app, especially the Fast and Lite tiers. Second, inside one app the tier you pay for changes the per-second price by more than half. Always divide the plan price by the credits, then multiply by the credits per second of the exact model variant.

Cost per usable second, not cost per second

The number that matters is not what one generation costs. It is what one usable second costs after retries.

A simple formula:

cost per usable second = (credit price x credits per second x seconds generated) / seconds you actually keep

Character and dialogue shots usually need more retries than simple b-roll. Suppose a model costs $0.12 per second and you keep one clip in four: your real cost is $0.48 per usable second. A pricier model that gets it right in two tries can be cheaper overall.

So run a small test before you commit a month's budget. Write five prompts that look like your real work, generate each in two or three places, and count what you would publish. That ten-minute test tells you more than any pricing table, including ours.

Things that change the retry rate between apps even with the same model:

• Prompt enhancement. Apps can rewrite or "enhance" your prompt before it reaches the model, sometimes by default. That can help beginners and hurt precise shots, so look for the toggle.
• Default settings. Resolution, duration and "enhance" toggles vary by app, and each costs credits.
• Reference handling. How many reference images the app passes through, and whether it supports start and end frames, differs from the model's own limits.

What else differs besides price

Price is only one column. Check these for the specific model in the specific app:

All of these come from the listing pages in our directory, which link to each vendor. Before you rely on one for paid work, open the app's own plan page, because these columns change more often than prices.

Rights: whose terms apply?

When you generate through an aggregator, the aggregator's terms govern your output, not the model maker's. The model's licence matters mostly when you run it yourself.

That cuts both ways. Krea and Magnific list a commercial licence on their paid plans; Higgsfield's help centre says you own your outputs. Adobe Firefly says outputs from its own Firefly models are safe for commercial use, but for partner models such as Veo or Kling inside Firefly, it leaves the judgement to you. Some apps simply don't state per-tier commercial terms on the pricing page.

Also check what the app can do with your uploads. Some consumer apps take broad licences to the content you put in, which matters if you upload client product shots or your own face.

Our /rights page summarises commercial use and watermarks by app, and /disclosure covers when platforms want AI-generated video labelled. This is not legal advice; for client or ad work, read the terms of the exact plan you pay for.

When to go direct, when to use an aggregator

Go to the maker's app or API when:

• You use one model for most of your work. Direct is usually cheaper per second at volume.
• You need the newest version or a feature on launch day (4K, a new editing mode, longer clips). Aggregators follow weeks or months later.
• You want the full control surface: every setting the model supports, not the subset an app exposes.
• You automate. APIs bill per second or per image as you go, instead of monthly credits that may expire. See /guides/developer if you are building that.

Use an aggregator when:

• You switch models by shot: Kling for talking characters, Veo for realism with sound, Seedance for long takes, FLUX or Nano Banana for stills. One subscription beats four.
• You are still testing which model suits your style.
• You want one editor, one asset library and one bill.
• The aggregator's plan includes relaxed or unlimited generations on a model you actually use.

A common split for a solo creator: one aggregator plan for exploration and variety, plus the maker's own app or API for the one model that produces most of your published footage. Check /apps/higgsfield/models or /apps/krea/models against your list of must-have models before you subscribe, and look at the model's own page, such as /models/kling, for every app that carries it.

The Sora lesson: don't build on one model

OpenAI closed the Sora app on 26 April 2026 and shut down the Sora 2 API on 24 September 2026. OpenAI's deprecation page lists no recommended replacement for the Videos API.

If your channel's look depended on Sora, you had to rebuild prompts, reference setups and style on another model, often in another app. The creators who moved fastest were the ones who had kept their assets outside the model: reference images, character sheets, prompt notes and finished clips stored in their own folders, not only inside one app's history.

There is a second lesson in how aggregators handled it. When we checked, some apps' model lists and pricing tables still showed Sora 2 after the API had gone. A listed model is not a guarantee of an available model. Aggregators are often the last to update and the first to charge you if you don't notice.

What model lock-in protection looks like in practice:

• Keep your inputs portable. Reference images, character sheets, prompts and brand frames live in your own storage.
• Write prompts in plain language, not in one app's special syntax or presets.
• Download every clip you keep, at full resolution, as soon as you make it. App history is not an archive.
• Keep a second model tested for your main shot types, so a shutdown or a price change costs you a week, not a month.
• Prefer monthly over yearly on aggregators unless the discount is large, because the model you are paying for may leave.

Takeaways

• The same model is sold by its maker's app, its API and many aggregators, at very different prices per second.
• Compare the exact variant (Lite, Fast, Standard), then divide plan price by credits and multiply by credits per second.
• Judge cost per usable second after retries, using a five-prompt test in two or three apps.
• Check version, max length, resolution, audio, editing tools, watermark and commercial rights for the tier you will pay for.
• Go direct for one main model, volume, newest features or automation; use an aggregator for variety and testing.
• Sora's shutdown shows why your references, prompts and finished clips should live outside any single model or app.
