|
||||
Which AI video generator should you actually use in 2026 — and how much of it can you really get for free?
|
||||
|
||||
AI video has changed faster than almost any other creative tool I've used. A year ago, decent video generation meant a paid subscription and hoping for the best. Today you can generate synchronized video *and* audio with an open-weight model on your own GPU, or get genuinely useful free credits from half a dozen platforms.
|
||||
|
||||
But there's a catch hiding in the word "free". It means at least four different things in this market, and most articles don't tell you which one they're talking about. This guide compares the options that are actually usable in 2026, separates marketing from reality, and ends with a hands-on test: I generated a short video with the open-weight model **LTX-2.3** through PinkCherry, and I'll show you the result.
|
||||
|
||||
*Pricing and free quotas below were checked on September 11, 2026. This market moves monthly — always verify against the provider's current pricing page before you commit.*
|
||||
|
||||
## What "free" actually means in 2026
|
||||
|
||||
Before comparing tools, you need to decode the word. There are four different deals hiding behind "free AI video generator":
|
||||
|
||||
1. **Free daily or monthly credits** — you get a set number of credits that refresh. Pika (80/month), PixVerse (daily), and Kling (66/day) work this way.
|
||||
2. **A one-time free trial** — you get an allocation once, and it never comes back. Runway's 125 credits are the classic example.
|
||||
3. **Open weights** — the model itself is free to download and run. But "free model" doesn't mean free *compute*: you still need a GPU, electricity, and setup time.
|
||||
4. **A hosted demo or community platform** — someone else runs the model for you (like PinkCherry, where I tested LTX-2.3). Quotas, queues, and availability can change without notice.
|
||||
|
||||
Same word, wildly different economics. A platform advertising "free AI video" is usually meaning #1 or #2. A model card advertising "free" is meaning #3 — and it quietly shifts the cost to your hardware.
|
||||
|
||||
## Why "model" and "platform" aren't the same thing
|
||||
|
||||
Another distinction that trips people up: **Seedance 2.5, Kling, and Veo are models. PixVerse, fal.ai, and Runway are platforms** — and platforms often resell each other's models.
|
||||
|
||||
Concrete example: Seedance 2.5 is ByteDance's model. You can use it through ByteDance's own products, through PixVerse (where it generates up to 30-second clips), or through fal.ai's API. Each route has different pricing, and none of those prices is "the" Seedance price. Kling is even messier — its own subscription copy references "Video 2.6" while third parties resell a "Kling 3.0" endpoint, so trust the model picker, not the blog posts.
|
||||
|
||||
This matters because comparing "Seedance vs PixVerse" is comparing a model against a platform. Compare like with like: model-to-model, platform-to-platform, and API-to-API.
|
||||
|
||||
## Quick comparison
|
||||
|
||||
| Tool | Free option | Paid option | Max clip | Native audio | Open/local | Best for |
|
||||
|---|---|---|---|---|---|---|
|
||||
| Pika | 80 credits/mo, 480p, watermarked | from ~$8/mo | ~5–10s | SFX | No | fast social clips |
|
||||
| PixVerse | 90 signup + 60 daily credits | from ~$10/mo | up to 30s (Seedance 2.5) | model-dependent | No | many models in one place |
|
||||
| Kling | 66 credits/day, 5s, 720p, non-commercial | from ~$7–10/mo | 10s | yes (paid) | No | value + motion physics |
|
||||
| Seedance 2.5 (via fal.ai API) | none | ~$0.22–1.16/s | up to 30s | yes | No | cinematic short clips |
|
||||
| Veo 3.1 (Gemini API) | none on API (limited free in Gemini app) | $0.05–0.40/s | 8s (+ extend) | yes | No | top quality |
|
||||
| Runway | 125 one-time credits | from ~$12–15/mo | 10s + extend | via bundled models | No | creative editing workflow |
|
||||
| Hailuo (MiniMax) | generous daily credits, watermarked | from ~$10–15/mo | 6s | no | No | free previz |
|
||||
| Luma (Ray3) | ~30 gen/mo, watermarked | from ~$25–30/mo | ~10s | no | No | cinematic look |
|
||||
| LTX-2.3 / LTX-2.5 | open weights, free under $10M ARR | LTX API from ~$0.09/s | ~10s | yes | Yes | local / self-hosted |
|
||||
| Wan 2.2 | open weights (Apache 2.0) | — | ~5–10s | no | Yes | local, no audio needed |
|
||||
| Sora 2 | — shutting down Sept 24, 2026 | $0.10–0.70/s until sunset | up to 20s | yes | No | avoid — being retired |
|
||||
|
||||
More detail on each below. Remember: **credits are not seconds**. "2,000 credits" sounds huge until you learn one 10-second 1080p clip costs 70–100 of them.
|
||||
|
||||
## 1. Pika — the cheapest real starting point
|
||||
|
||||
Pika's free Basic plan gives you **80 monthly credits** — roughly five or six 5-second 480p clips a month. It's watermarked, capped at 480p, and has no commercial use and no watermark-free download (those start on paid plans). Several older articles claim Pika's free tier is watermark-free; as of September 2026 that is *not* true.
|
||||
|
||||
Paid plans start around **$8/month**. For the money you get faster generation, higher resolution, Pikaffects (explosion, melt, morph effects built for virality), and keyframe control.
|
||||
|
||||
**Best for:** people who want the lowest-friction way to make fun short-form clips for social media. Not for serious cinematic work — raw quality trails Veo, Kling, and Seedance.
|
||||
|
||||
## 2. PixVerse — many models, one credit balance
|
||||
|
||||
PixVerse is the clearest example of the model-vs-platform distinction. One account, one credit pool, and a model selector that includes **Seedance 2.5, Seedance 2.0, Kling, Veo 3.1, and its own V6** — which makes it the easiest place to compare models side-by-side without five subscriptions.
|
||||
|
||||
Free tier: **90 signup credits plus 60 daily credits** — roughly a video or two a day depending on model and resolution. Paid plans start around $10/month and unlock higher resolutions and the bigger models (Seedance 2.5 itself is currently gated to paid members).
|
||||
|
||||
Pricing is per-second and varies wildly by model and resolution — Seedance 2.5 costs far more per second than the in-house V6. That's why comparing tools by "price per video" without naming the model and resolution is meaningless.
|
||||
|
||||
**Best for:** people who want to try many models in one place and compare output quality directly.
|
||||
|
||||
## 3. Kling — best value for motion, with a confusing tier ladder
|
||||
|
||||
Kling (Kuaishou) is the value leader in 2026. Its **Kling 3.0** model (released February 2026) tops the Artificial Analysis image-to-video leaderboard, with notably believable physics — cloth, water, hair.
|
||||
|
||||
The free tier gives **66 credits per day** (they reset every 24 hours, they don't accumulate, and the exact amount can vary by region and account age). The catch is on three levels: output is **watermarked**, **non-commercial**, and — the part most reviews bury — free users get the *older* Kling 2.1 at 5 seconds and 720p. Kling 3.0 starts on paid plans.
|
||||
|
||||
Paid plans list from about **$10/month** (intro promos around $7, renewal higher) for 660 credits. Watch two gotchas: subscription credits don't roll over, and failed generations still deduct credits.
|
||||
|
||||
**Best for:** creators who want the strongest motion quality per dollar and don't need the free tier for anything commercial.
|
||||
|
||||
## 4. Seedance 2.5 — powerful, but read the pricing carefully
|
||||
|
||||
Seedance 2.5 is ByteDance's current flagship. It does text-to-video, image-to-video, and **reference-to-video** (multiple reference images for visual consistency), with native audio and generation up to **30 seconds** — unusually long for a single clip.
|
||||
|
||||
There is no universal Seedance price, because the model isn't sold directly at one price. On **fal.ai**, an independent API provider, approximate standard pricing is:
|
||||
|
||||
- **480p: ~$0.22/second**
|
||||
- **720p: ~$0.47/second**
|
||||
- **1080p: ~$1.16/second** (rolled out August 2026)
|
||||
|
||||
A 10-second 720p clip on fal runs about **$4.70**. WaveSpeed lists 1080p around $0.90/second. On PixVerse, Seedance 2.5 is available to paid members at per-second credit rates. These are *third-party* prices — ByteDance's own consumer products price differently — but they're the realistic numbers if you're building on an API.
|
||||
|
||||
**Best for:** filmmakers and developers who want cinematic, consistent short clips and are comparing API economics, not consumer subscriptions.
|
||||
|
||||
## 5. Google Veo 3.1 — the quality crown, with three speed tiers
|
||||
|
||||
Most independent testing in 2026 puts **Veo 3.1** at the top for realism and prompt accuracy, and it generates synchronized audio in the same pass. Google's official API documentation lists 8-second clips at 720p, 1080p, or 4K, with extension, first/last-frame control, and up to three reference images.
|
||||
|
||||
The API has **no free tier** — everything is pay-per-second:
|
||||
|
||||
- **Veo 3.1 Lite: $0.05/s** (720p) — cheap iteration
|
||||
- **Veo 3.1 Fast: $0.10/s** (720p), $0.12/s (1080p), $0.30/s (4K)
|
||||
- **Veo 3.1 Standard: $0.40/s** (720p and 1080p), $0.60/s (4K)
|
||||
|
||||
Consumers can try Veo free inside the Gemini app on limited daily usage — the API itself is paid-only. Note that Veo 3 was deprecated on June 30, 2026; 3.1 is the current line, and Google has also previewed **Gemini Omni Flash**, a video generation *and editing* model around $0.10/s.
|
||||
|
||||
**Best for:** anyone who wants the best output and is fine paying per clip — and developers who want predictable per-second API costs.
|
||||
|
||||
## 6. Runway — a creative workflow, not just a generator
|
||||
|
||||
Runway has become a video *workspace*: its Gen-4.5 model plus a real editing timeline, motion brushes, inpainting, and character consistency — and it now **resells Veo 3.1, Kling, and Seedance inside the same editor**. One subscription, many models. That aggregation is the real reason to pay.
|
||||
|
||||
The free tier is the clearest example of "one-time trial": **125 credits, once, ever**. They don't renew, the free tier is image-to-video only with a watermark, and it can't touch Gen-4.5 or Veo.
|
||||
|
||||
Paid: Standard ~$12–15/month for 625 credits, Pro ~$28–35/month for 2,250, Max ~$76–95/month. Do the credit math before buying: Gen-4.5 burns roughly 12–25 credits per second, so the Standard plan's 625 credits is only about **25–50 seconds** of flagship video a month.
|
||||
|
||||
**Best for:** creators who need to stitch clips into longer cuts, hold a consistent character, and edit — not just prompt.
|
||||
|
||||
## 7. Hailuo and Luma — the "worth knowing" pair
|
||||
|
||||
**Hailuo (MiniMax)** has the most genuinely usable free tier for evaluation: generous daily credits, watermarked, 6-second clips. Quality for realistic human motion punches well above its price. Paid from ~$10–15/month; API around $0.07–0.08/second makes it one of the cheapest serious options for developers.
|
||||
|
||||
**Luma (Ray3)** is the rare tool with a real HDR and color pipeline (16-bit HDR, EXR export) aimed at actual film workflows. Free tier gives roughly 30 watermarked generations a month; paid plans sit around $25–30/month — pricier than Pika or Kling, and the free allowance is small. It's the pick if you want a cinematic look and work in film-oriented formats.
|
||||
|
||||
## What happened to Sora 2 — and why you should care
|
||||
|
||||
If you've read older guides, you'll notice Sora 2 is missing from the recommendations. OpenAI **discontinued the Sora app on April 26, 2026**, and the Sora API is scheduled to **shut down on September 24, 2026**. As of this writing, you cannot buy a Sora subscription, and building on the API means migrating in days.
|
||||
|
||||
It's a useful lesson in how fast this market turns: a model that was "best overall" in early 2026 is gone before the year ends. When you choose a platform or model for real work, check *when* it was last updated and whether the company is still shipping — the best model in the world is useless if the API sunset is next month.
|
||||
|
||||
## LTX-2.3 and LTX-2.5 — the interesting open/local route
|
||||
|
||||
This is the part that changes the economics. **LTX** is the open-weights video line from Lightricks (now spun out as LTX). It's an audio-video foundation model: video and synchronized audio generated in a single pass — dialogue, lip-sync, ambience — which was a hosted-only capability until recently.
|
||||
|
||||
- **LTX-2.3** (March 2026) — the version I tested. Open weights, synchronized audio, portrait and landscape.
|
||||
- **LTX-2.5** (August 11, 2026) — the current release. 22B parameters, native **multishot** generation (several connected scenes in one output, holding character, lighting, and voice across cuts), 4K HDR, a new diffusion video decoder with fewer artifacts, and a **Gemma 4** text encoder. Day-one ComfyUI support.
|
||||
|
||||
Licensing matters here: it's the LTX Community License, **free for commercial use if your company earns under $10M ARR** — no mandatory branding, no per-seat fees. Above that, you negotiate a paid license.
|
||||
|
||||
You can run it three ways: self-hosted on your own GPU (roughly 16–24GB VRAM reported for reasonable speeds — check the current requirements), through ComfyUI workflows, or via the LTX API (from about **$0.09/second at 720p**).
|
||||
|
||||
Why this is a big deal: an open-weights model with synchronized audio changes the cost question from "what's the subscription?" to "what's my GPU budget?". The trade-off is real — setup time, hardware cost, and results that depend heavily on your workflow, quantization, and settings. But for experimentation, learning, and full control, nothing else in this list compares.
|
||||
|
||||
## My LTX-2.3 test
|
||||
|
||||
I generated this short clip with **LTX-2.3** through **PinkCherry**, a hosted playground for open-weight models. It's a real-world test, not a benchmark — no claims about speed or quality leadership here, just what the model did when I pointed it at a prompt and let it work.
|
||||
|
||||

|
||||
|
||||
*My LTX-2.3 demo clip, generated via PinkCherry (hosted on content.hoelee.com).*
|
||||
|
||||
What made this experiment interesting wasn't that LTX beats the commercial models — on raw polish it doesn't need to, and I'm not going to claim otherwise. It's that this is an **open-weight, local-oriented model**:
|
||||
|
||||
- **Different cost structure.** No subscription, no per-clip API bill. The cost moves to GPU hardware, electricity, and setup time — which is a *capital* cost you can amortize, not a recurring one.
|
||||
- **More control.** You can run it in ComfyUI, swap checkpoints, quantize to fit your VRAM, and fine-tune under the community license.
|
||||
- **It's the model's job to evolve fast.** I tested 2.3; 2.5 shipped a month later with multishot and 4K HDR. Open weights mean you don't wait for a company to upgrade you.
|
||||
|
||||
The honest caveats: your results depend heavily on hardware, workflow, model version, and quantization. A hosted playground like PinkCherry is meaning #4 of "free" — great for a first taste, but queues and quotas can change, and serious local use means learning ComfyUI.
|
||||
|
||||
If you want to try it yourself: grab the weights from Hugging Face, or use a playground like PinkCherry for a first test, then decide if local setup is worth it. For me, it was — which is exactly why this article exists.
|
||||
|
||||
## Can you make a 3-minute AI video?
|
||||
|
||||
The honest answer: not in one shot. Even models with 30-second generation (Seedance 2.5) or extension (Veo) are **short-clip generators**, not feature-film machines. Maximum duration is not the same as the ability to produce a polished long-form video — coherence, consistency, and pacing all degrade the longer a single generation runs.
|
||||
|
||||
The practical workflow everyone actually uses:
|
||||
|
||||
```
|
||||
Script → scenes → short AI clips (10–15s each) → edit → voice/music/sound → final video
|
||||
```
|
||||
|
||||
The math is simple: **15 × 12-second clips = 180 seconds = 3 minutes.** A 3-minute YouTube video is fifteen generated clips, cut together, with audio layered on top. That's why the "max clip length" column in my table matters less than you'd think — you're going to edit regardless.
|
||||
|
||||
## Free vs paid: what should you choose?
|
||||
|
||||
There is no single winner — the right tool depends on who you are:
|
||||
|
||||
| You are... | Try this |
|
||||
|---|---|
|
||||
| Complete beginner | Pika or PixVerse free credits — learn the workflow at $0 |
|
||||
| Casual creator, no commercial need | Hailuo's daily credits — best free quality |
|
||||
| Budget social-media creator | Kling Standard (~$7–10/mo) or Pika (~$8/mo) |
|
||||
| YouTube / short-form creator | Kling for clips + Runway for editing, or PixVerse for multi-model comparison |
|
||||
| Business / product video | Paid tier with commercial rights — Veo (via API), Kling, or Runway |
|
||||
| Developer building an app | Compare APIs: Veo Lite ($0.05/s), Seedance via fal, Kling via partners, LTX API (~$0.09/s) |
|
||||
| You own a decent GPU | LTX-2.5, Wan 2.2, or HunyuanVideo 1.5 — free per clip, cost is hardware |
|
||||
|
||||
The four questions that decide it: **how often** do you generate, **do you need commercial use**, **do you need native audio**, and **do you already own a suitable GPU**. Answer those and the table above picks itself.
|
||||
|
||||
## Final thoughts
|
||||
|
||||
2026's AI video landscape rewards people who read the fine print. "Free" is four different deals. Credits are not seconds. Models are not platforms. And the market moves fast enough that a category leader can vanish in a year — Sora is the cautionary tale.
|
||||
|
||||
My practical recommendation: start with **PixVerse** (many models, one credit pool) or **Kling's daily credits** to learn what you actually like, compare against **Veo 3.1** when quality matters, and seriously consider the **LTX open-weight route** if you have any interest in local generation — my own test convinced me it's a genuinely different (and cheaper) path.
|
||||
|
||||
This isn't my first ride on the open-weights train — I wrote about [generating product images locally with Flux Kontext](https://blog.hoelee.com/posts/ai-furniture-compositing-with-flux-kontext/) a while back, and the same lesson applies here: open weights trade setup effort for control and long-term cost.
|

|
||||
|
||||
2026 年，你究竟该用哪个 AI 视频生成器？其中又有多少是真免费的？
|
||||
|
||||
AI 视频是我用过的工具里变化最快的领域之一。一年前，像样的视频生成意味着付费订阅再加一点运气；今天，你既可以用开源权重模型在自己的 GPU 上生成视频和同步音频，也能从六七个平台领到真正可用的免费额度。
|
||||
|
||||
但"免费"这个词里藏着一个陷阱：在这个市场里它有至少四种含义，而大多数文章不会告诉你它说的是哪一种。这份指南对比了 2026 年真正能用的主要选择，把营销话术和现实分开，最后以一个亲手实验收尾——我用开源权重模型 **LTX-2.3**（通过 PinkCherry）生成了一段短视频，并会把结果展示给你看。
|
||||
|
||||
*下文的价格与免费额度核实于 2026 年 9 月 11 日。这个市场每个月都在变——下单前请务必到服务商当前的价格页确认。*
|
||||
|
||||
## 2026 年，"免费"到底意味着什么
|
||||
|
||||
在对比工具之前，先要解码"免费"这个词。所谓"免费 AI 视频生成器"背后其实是四种完全不同的东西：
|
||||
|
||||
1. **每日或每月免费额度**——你获得一定数量的积分，定期刷新。Pika（每月 80 积分）、PixVerse（每日）和 Kling（每日 66）都属于这一类。
|
||||
2. **一次性试用**——给你一笔额度，用完就再也没有了。Runway 的 125 积分是最典型的例子。
|
||||
3. **开源权重**——模型本身可以免费下载和运行。但"模型免费"不等于"算力免费"：你仍然需要 GPU、电费和搭建时间。
|
||||
4. **托管演示或社区平台**——别人替你跑模型（比如我测试 LTX-2.3 用的 PinkCherry）。额度、队列和可用性都可能随时变化。
|
||||
|
||||
同一个词，成本结构天差地别。平台宣传"免费 AI 视频"时通常指第 1 或第 2 种；模型卡上写"免费"通常指第 3 种——成本悄悄转移到了你的硬件上。
|
||||
|
||||
## 为什么"模型"和"平台"不是一回事
|
||||
|
||||
另一个容易混淆的地方：**Seedance 2.5、Kling、Veo 是模型；PixVerse、fal.ai、Runway 是平台**——而且平台经常转售彼此的模型。
|
||||
|
||||
具体例子：Seedance 2.5 是字节跳动的模型。你可以通过字节自家的产品使用它，也可以通过 PixVerse 使用（那里最长能生成 30 秒的片段），或者通过 fal.ai 的 API 调用。每条路径的定价都不同，其中没有任何一个是"官方"Seedance 价格。Kling 更乱——它自己的订阅文案提到"Video 2.6"，而第三方转售的是"Kling 3.0"接口，所以请相信模型选择器，别信博客文章。
|
||||
|
||||
这一点很重要：把"Seedance 对比 PixVerse"等于拿模型对比平台。要比就同类比——模型对模型、平台对平台、API 对 API。
|
||||
|
||||
## 快速对比表
|
||||
|
||||
| 工具 | 免费选项 | 付费选项 | 最长片段 | 原生音频 | 开源/本地 | 最适合 |
|
||||
|---|---|---|---|---|---|---|
|
||||
| Pika | 每月 80 积分，480p，带水印 | 约 $8/月起 | 约 5–10s | 音效 | 否 | 快速社交媒体短片 |
|
||||
| PixVerse | 注册送 90 + 每日 60 积分 | 约 $10/月起 | 最长 30s（Seedance 2.5） | 视模型而定 | 否 | 一个平台用多个模型 |
|
||||
| Kling | 每日 66 积分，5s，720p，不可商用 | 约 $7–10/月起 | 10s | 有（付费版） | 否 | 性价比 + 运动物理 |
|
||||
| Seedance 2.5（fal.ai API） | 无 | 约 $0.22–1.16/秒 | 最长 30s | 有 | 否 | 电影感短片 |
|
||||
| Veo 3.1（Gemini API） | API 无免费档（Gemini 应用内有限免费） | $0.05–0.40/秒 | 8s（可续接） | 有 | 否 | 顶级质量 |
|
||||
| Runway | 125 一次性积分 | 约 $12–15/月起 | 10s + 续接 | 随捆绑模型 | 否 | 创意剪辑工作流 |
|
||||
| Hailuo（MiniMax） | 慷慨的每日积分，带水印 | 约 $10–15/月起 | 6s | 无 | 否 | 免费预演 |
|
||||
| Luma（Ray3） | 每月约 30 次生成，带水印 | 约 $25–30/月起 | 约 10s | 无 | 否 | 电影感画面 |
|
||||
| LTX-2.3 / LTX-2.5 | 开源权重，年营收 <$1000 万免费 | LTX API 约 $0.09/秒起 | 约 10s | 有 | 是 | 本地/自托管 |
|
||||
| Wan 2.2 | 开源权重（Apache 2.0） | — | 约 5–10s | 无 | 是 | 本地、不需要音频 |
|
||||
| Sora 2 | — 2026 年 9 月 24 日停服 | 停服前 $0.10–0.70/秒 | 最长 20s | 有 | 否 | 别用——即将退役 |
|
||||
|
||||
每个工具的详情见下。请记住：**积分不等于秒数**。"2000 积分"听起来很多，直到你发现一个 10 秒 1080p 的片段要花掉 70–100 积分。
|
||||
|
||||
## 1. Pika——门槛最低的入门选择
|
||||
|
||||
Pika 的免费 Basic 套餐每月给 **80 积分**——大约够生成五六个 5 秒、480p 的片段。输出带水印、限 480p，**不可商用、也不能无水印下载**（这些都要从付费套餐开始）。不少旧文章说 Pika 免费层无水印；截至 2026 年 9 月，这并非事实。
|
||||
|
||||
付费套餐约 **$8/月起**。换来更快的生成速度、更高分辨率、Pikaffects 特效（爆炸、融化、变形等专为传播设计的特效）和关键帧控制。
|
||||
|
||||
**适合**：想用最低门槛做社交平台短片的用户。不适合严肃的电影级创作——画质与 Veo、Kling、Seedance 有明显差距。
|
||||
|
||||
## 2. PixVerse——一个积分池，多个模型
|
||||
|
||||
PixVerse 是"模型 vs 平台"最清楚的例子。一个账号、一个积分池、一个模型选择器，里面包括 **Seedance 2.5、Seedance 2.0、Kling、Veo 3.1** 和自家的 V6——不想买五个订阅就并排对比模型，这里最方便。
|
||||
|
||||
免费层：**注册送 90 积分 + 每日 60 积分**——按模型和分辨率不同，大约每天能出一到两条视频。付费约 $10/月起，解锁更高分辨率和更大的模型（Seedance 2.5 目前只对付费会员开放）。
|
||||
|
||||
定价按秒计算，且因模型和分辨率差异巨大——Seedance 2.5 每秒比自家的 V6 贵得多。这就是为什么"不指明模型和分辨率、只谈每条视频多少钱"的对比毫无意义。
|
||||
|
||||
**适合**：想在一个地方试遍多个模型、直接对比输出质量的人。
|
||||
|
||||
## 3. Kling——运动效果性价比之王，但层级阶梯让人困惑
|
||||
|
||||
Kling（快手）是 2026 年的性价比之选。它的 **Kling 3.0** 模型（2026 年 2 月发布）位列 Artificial Analysis 图生视频排行榜第一，物理效果（布料、水、头发）尤其逼真。
|
||||
|
||||
免费层给 **每日 66 积分**（每 24 小时重置、不累积，具体数额可能因地区和账号而异）。坑有三层：输出**带水印**、**不可商用**，而且——大多数评测会忽略的一点——免费用户只能用**旧版 Kling 2.1**，5 秒、720p。Kling 3.0 从付费套餐开始。
|
||||
|
||||
付费约 **$10/月** 起（首月促销约 $7，续费更高），含 660 积分。两个坑要当心：订阅积分月底清零、不滚动；生成失败照样扣积分。
|
||||
|
||||
**适合**：追求"每美元最多运动质量"、且免费层无需商用的创作者。
|
||||
|
||||
## 4. Seedance 2.5——很强，但请仔细看价格
|
||||
|
||||
Seedance 2.5 是字节跳动当前的旗舰。支持文生视频、图生视频和**参考图生视频**（用多张参考图保持视觉一致性），原生音频，单次生成最长 **30 秒**——这在单段生成里相当少见。
|
||||
|
||||
Seedance 没有"统一价格"，因为这个模型并不是以单一价格直接销售的。在独立 API 服务商 **fal.ai** 上，大约的标价为：
|
||||
|
||||
- **480p：约 $0.22/秒**
|
||||
- **720p：约 $0.47/秒**
|
||||
- **1080p：约 $1.16/秒**（2026 年 8 月上线）
|
||||
|
||||
在 fal 上，一个 10 秒 720p 的片段约 **$4.70**。WaveSpeed 的 1080p 报价约 $0.90/秒。在 PixVerse 上，Seedance 2.5 对付费会员按秒积分计费。这些都是**第三方**价格——字节自家消费产品的定价不同——但如果你想基于 API 构建，这才是现实的数字。
|
||||
|
||||
**适合**：想要电影感、一致性强的短片，并且在对比 API 成本（而非消费订阅）的电影人和开发者。
|
||||
|
||||
## 5. Google Veo 3.1——质量之冠，三个速度档
|
||||
|
||||
2026 年多数独立测试把 **Veo 3.1** 排在真实感和提示词还原度的第一位，而且它能在同一次生成中产出同步音频。Google 官方 API 文档列出 8 秒片段，支持 720p/1080p/4K，可续接、可指定首尾帧、最多三张参考图。
|
||||
|
||||
API **没有免费档**——全部按秒计费：
|
||||
|
||||
- **Veo 3.1 Lite：$0.05/秒**（720p）——便宜的迭代选项
|
||||
- **Veo 3.1 Fast：$0.10/秒**（720p）、$0.12/秒（1080p）、$0.30/秒（4K）
|
||||
- **Veo 3.1 Standard：$0.40/秒**（720p 与 1080p）、$0.60/秒（4K）
|
||||
|
||||
普通用户可以在 Gemini 应用里以每日限量免费试用 Veo；API 本身只付费。注意 Veo 3 已于 2026 年 6 月 30 日弃用，3.1 才是当前系列。Google 还预览了 **Gemini Omni Flash**——一个既能生成又能编辑视频的模型，约 $0.10/秒。
|
||||
|
||||
**适合**：想要最好输出且不介意按条付费的人，以及需要可预测的每秒 API 成本的开发者。
|
||||
|
||||
## 6. Runway——一整套创作工作流，而不只是生成器
|
||||
|
||||
Runway 已经变成一个视频*工作台*：自有 Gen-4.5 模型，加上真正的剪辑时间线、运动笔刷、局部重绘、角色一致性——现在还能在**同一个编辑器里使用 Veo 3.1、Kling 和 Seedance**。一个订阅、多个模型。这个聚合能力才是付费的真正理由。
|
||||
|
||||
免费层是"一次性试用"最清楚的例子：**125 积分，总共一次，永远不会刷新**。免费层只能图生视频、带水印，而且不能用 Gen-4.5 和 Veo。
|
||||
|
||||
付费：Standard 约 $12–15/月（625 积分），Pro 约 $28–35/月（2250 积分），Max 约 $76–95/月。买之前先算积分账：Gen-4.5 每秒大约烧掉 12–25 积分，所以 Standard 的 625 积分只够旗舰模型生成**约 25–50 秒**的视频。
|
||||
|
||||
**适合**：需要把片段剪成长片、跨镜头保持角色一致、并且要做后期编辑——而不只是写提示词的创作者。
|
||||
|
||||
## 7. Hailuo 与 Luma——"值得知道"的一对
|
||||
|
||||
**Hailuo（MiniMax）** 的免费层最适合用来评估：每日积分慷慨、带水印、6 秒片段，真人动作的质量远超它的价格带。付费约 $10–15/月；API 约 $0.07–0.08/秒，是开发者最便宜的严肃选项之一。
|
||||
|
||||
**Luma（Ray3）** 是少有的带真实 HDR 和调色管线的工具（16-bit HDR、EXR 导出），面向真正的电影工作流。免费层每月约 30 次带水印的生成；付费约 $25–30/月——比 Pika 或 Kling 贵，免费额度也小。想要电影感画面、又工作在影视格式里的人选它。
|
||||
|
||||
## Sora 2 怎么了——以及为什么你该在意
|
||||
|
||||
如果你读过旧指南，会注意到推荐名单里没有 Sora 2。OpenAI 已于 **2026 年 4 月 26 日**停掉 Sora 应用，Sora API 也计划于 **2026 年 9 月 24 日**关停。写这篇文章时，你已经无法购买 Sora 订阅；基于它的 API 构建意味着几天内就要迁移。
|
||||
|
||||
这也是这个市场变化之快的一个教训：一个 2026 年初还"综合最佳"的模型，年底前就消失了。为实际工作选择平台或模型时，先查它最近一次更新时间，以及背后的公司是否还在迭代——再好的模型，如果下个月就停服，也毫无用处。
|
||||
|
||||
## LTX-2.3 与 LTX-2.5——有意思的开源/本地路线
|
||||
|
||||
这部分会改变成本结构。**LTX** 是 Lightricks（现已分拆为独立公司 LTX）的开源权重视频系列，是一个音视频基础模型：视频和同步音频在单次生成中完成——对白、口型、环境音一气呵成。这在不久之前还是托管服务独有能力。
|
||||
|
||||
- **LTX-2.3**（2026 年 3 月）——我测试的版本。开源权重、同步音频、横竖屏都支持。
|
||||
- **LTX-2.5**（2026 年 8 月 11 日）——当前版本。22B 参数，原生**多镜头**生成（一次输出多个连贯场景，跨镜头保持角色、光影和声音一致），4K HDR，新的扩散视频解码器（伪影更少），加上 **Gemma 4** 文本编码器。发布当天即支持 ComfyUI。
|
||||
|
||||
授权在这里很关键：采用 LTX 社区许可，**公司年营收低于 1000 万美元即可免费商用**——没有强制品牌署名、没有按席位收费。超过门槛则需单独洽谈付费许可。
|
||||
|
||||
运行方式有三种：在自己的 GPU 上自托管（据报告约需 16–24GB 显存，请以最新要求为准）、通过 ComfyUI 工作流运行，或使用 LTX API（720p 约 **$0.09/秒** 起）。
|
||||
|
||||
为什么这很重要：一个带同步音频的开源权重模型，把成本问题从"订阅多少钱？"变成了"我的 GPU 预算是多少？"。代价也是真实的——搭建时间、硬件成本，而且结果高度依赖你的工作流、量化方式和设置。但对实验、学习和完全掌控来说，这份名单里没有对手。
|
||||
|
||||
## 我的 LTX-2.3 实测
|
||||
|
||||
这段短片是我用 **LTX-2.3** 通过 **PinkCherry**（一个托管开源模型的在线游乐场）生成的。这是一个真实世界的测试，不是基准评测——我不对速度或质量优势做任何宣称，只是展示这个模型在我给出提示词、放手让它跑的时候做了什么。
|
||||
|
||||

|
||||
|
||||
*我的 LTX-2.3 演示片段，通过 PinkCherry 生成（托管于 content.hoelee.com）。*
|
||||
|
||||
这个实验有意思的地方，不在于 LTX 打败了商业模型——论精细度它并不需要，我也不会这么宣称。而在于这是一个**开源权重、面向本地**的模型：
|
||||
|
||||
- **成本结构不同。** 没有订阅，没有按条计的 API 账单。成本转移到了 GPU 硬件、电费和搭建时间上——这是一次性投入（可以摊薄），不是持续支出。
|
||||
- **掌控力更强。** 可以在 ComfyUI 里运行、更换检查点、量化以适配显存，还能在社区许可下微调。
|
||||
- **它升级得很快。** 我测试的是 2.3；一个月后 2.5 就带着多镜头和 4K HDR 发布了。开源权重意味着你不必等某家公司给你升级。
|
||||
|
||||
诚实的提醒：结果很大程度上取决于硬件、工作流、模型版本和量化方式。像 PinkCherry 这样的托管游乐场属于"免费"的第 4 种含义——适合第一次尝鲜，但队列和额度会变；要认真本地使用，意味着要学习 ComfyUI。
|
||||
|
||||
想自己试试：去 Hugging Face 下载权重，或者先用 PinkCherry 之类的游乐场试一把，再决定值不值得搭建本地环境。对我来说值得——这正是这篇文章存在的原因。
|
||||
|
||||
## 能做 3 分钟的 AI 视频吗？
|
||||
|
||||
诚实回答：不能一口气生成。即使是支持 30 秒（Seedance 2.5）或可续接（Veo）的模型，本质上也还是**短片生成器**，不是长片机器。单次生成越长，连贯性、一致性和节奏感就越差——"最长时长"和"能做出精良的长视频"不是一回事。
|
||||
|
||||
大家实际使用的工作流是：
|
||||
|
||||
```
|
||||
脚本 → 分镜 → 短 AI 片段（每段 10–15 秒）→ 剪辑 → 配音/音乐/音效 → 成片
|
||||
```
|
||||
|
||||
数学很简单：**15 × 12 秒 = 180 秒 = 3 分钟**。一条 3 分钟的 YouTube 视频，就是十五条生成片段剪在一起，再叠上音频。所以上表里"最长片段"这一列的实际影响，比你想的要小——反正你都要剪辑。
|
||||
|
||||
## 免费还是付费：你该选哪个？
|
||||
|
||||
没有唯一的赢家——合适的工具取决于你是谁：
|
||||
|
||||
| 你属于…… | 建议先试 |
|
||||
|---|---|
|
||||
| 完全新手 | Pika 或 PixVerse 的免费额度——零成本学会工作流 |
|
||||
| 偶尔创作、不需要商用 | Hailuo 的每日积分——免费里质量最好 |
|
||||
| 预算有限的社交媒体创作者 | Kling Standard（约 $7–10/月）或 Pika（约 $8/月） |
|
||||
| YouTube / 短视频创作者 | Kling 生成 + Runway 剪辑，或多模型对比用 PixVerse |
|
||||
| 商业 / 产品视频 | 带商用权的付费档：Veo（API）、Kling 或 Runway |
|
||||
| 开发者做应用 | 对比 API：Veo Lite（$0.05/秒）、fal 上的 Seedance、Kling 第三方接口、LTX API（约 $0.09/秒） |
|
||||
| 手里有一块不错的 GPU | LTX-2.5、Wan 2.2 或 HunyuanVideo 1.5——每条免费，成本在硬件 |
|
||||
|
||||
四个问题决定答案：**多久生成一次**、**需不需要商用权**、**需不需要原生音频**、**是不是已经有一块合适的 GPU**。答完这四个，上面的表自己就选出来了。
|
||||
|
||||
## 结语
|
||||
|
||||
2026 年的 AI 视频市场，奖励那些会读小字的人。"免费"是四种不同的交易；积分不是秒数；模型不是平台；市场变得太快，一年内就能让一个头部玩家消失——Sora 就是前车之鉴。
|
||||
|
||||
我的实用建议：先用 **PixVerse**（多个模型、一个积分池）或 **Kling 的每日积分**弄清自己喜欢什么；质量优先时对比 **Veo 3.1**；对本地生成有一点兴趣的话，认真考虑 **LTX 开源路线**——我的实测让我确信这是一条真正不同（也更便宜）的路。
|
||||
|
||||
这也不是我第一次接触开源权重——之前我写过用 [Flux Kontext 本地生成产品图](https://blog.hoelee.com/posts/ai-furniture-compositing-with-flux-kontext/) 的文章，道理是一样的：开源权重用搭建的功夫换来了掌控力和长期成本优势。
|
||||
|
||||
另外，当任何文章引用价格时——包括这篇——下单前请到服务商的价格页确认。**价格核实于 2026 年 9 月 11 日。**
