HeyGen: HeyGen Video vs MiniMax: H3
A side-by-side comparison of HeyGen: HeyGen Video ($0.35 / second) and MiniMax: H3 ($0.46 / second) using current USD prices and capabilities from the api14 catalog. Both run through the same OpenAI-compatible API.

In depth
HeyGen Video is a video generation model from HeyGen, published under the model id heygen/heygen-video-1. MiniMax H3 is a video generation model from MiniMax, published under the model id minimax/hailuo-3. Both sit in the video category on api14, and both are accessed through the same gateway, so the choice between them is about behaviour and control rather than about plumbing. HeyGen Video carries a provider release date of 2026-09-30, while H3 carries a provider release date of 2026-07-29.
On the surface the two models look very similar. Both accept text, image, video and audio as input, and both produce video as their only output. Neither lists a context length, so there is no documented token window to compare, and the qualitative fields for cheaper input, cheaper output and bigger context are all unset, which means there is no meaningful difference to report on price or context size. The one concrete difference is in supported parameters. H3 exposes max_tokens, temperature and top_p, so you can tune sampling behaviour and cap generation length from the request. HeyGen Video lists no supported parameters, so you send your inputs and take what the model returns, with no sampling knobs to adjust.
That difference should drive most of your decisions. If your pipeline needs deterministic-ish control over randomness, or you want to bound output length per call, H3 is the natural pick because temperature, top_p and max_tokens are available. If you are building something where you would rather not manage sampling settings at all, and you want the provider's own defaults to govern the result, HeyGen Video is the simpler target. The input modalities are identical, so tasks built around driving a video from a still image, an existing clip or an audio track are equally expressible on either model. Where you have no strong opinion on decoding parameters, treat them as interchangeable and decide on output quality from your own tests.
Calling either model through api14 works the same way, because the API is OpenAI-compatible. You point your existing client at the api14 base URL, send a chat-style request, and set the model field. To use HeyGen Video, set the model to heygen/heygen-video-1. To use H3, set the model to minimax/hailuo-3. Everything else in the request body stays as it is, apart from the optional parameters that only H3 accepts. That means switching between the two is a one-line change, which makes A/B testing straightforward: run the same prompt and the same input media against both ids and compare the resulting videos.
There is no case in the facts given where one model is clearly the better pick on capability grounds, since their modalities match and no benchmark or quality signal is provided. The only defensible tiebreaker is parameter support, and it favours H3 when you need temperature, top_p or max_tokens. If you do not need those, pick either, and let your own evaluation of the generated video decide.
Switch with one string
Both models use the same endpoint and request shape. Change the model value from "heygen/heygen-video-1" to "minimax/hailuo-3" and prompts, streaming and tools keep working.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api14.com/api/v1",
apiKey: process.env.API14_API_KEY,
});
// Video generation is asynchronous: submit, then poll until completed.
let job = await client.post("/videos", { body: {
"model": "minimax/hailuo-3",
"prompt": "A drone shot over turquoise ocean waves at sunrise",
"duration": 8,
"resolution": "720p",
"aspect_ratio": "16:9"
} });
while (!["completed", "failed"].includes(job.status)) {
await new Promise((r) => setTimeout(r, 5000));
job = await client.get(`/videos/${job.id}`);
}
console.log(job.status, job.unsigned_urls);
