What is the cheapest AI video generator?
The cheapest AI video generator on published figures is Hailuo, at roughly ten cents a clip on a promotional rate — and if you need something free that you can legally use commercially, Pika’s free tier is the only one on this list that unambiguously allows it. FlowPix is not in contention on either count, and the numbers below say so.

FlowPix gates video behind its Pro plan at $69/mo. Every tool on this page starts cheaper — several under $10 — and Pika gives you commercial-use video free. If your question is literally "what is the cheapest", the answer is not FlowPix and you should stop reading after the table.

| Pika | Yes — 80 credits/mo, 480p, no watermark, commercial use allowed. The only unambiguous free commercial option here | Standard $10/mo, or $8/mo billed yearly | 700 credits/mo ≈ 35 clips at 720p/5s. Max 25s on Standard |

この比較が成り立たなくなるところ
Two warnings before you use this table as a shopping list. First, the two cheapest headline numbers are introductory: Kling’s $6.99 and Hailuo’s $7.99 are first-subscription promotions, and the honest ongoing prices are $8.80 and $14.99. Second, a clip is not a unit — four seconds at 720p without audio and eight seconds at 1080p with audio cost the same word and very different money, and only Runway and Pika publish credit costs per model per second so you can tell the difference. Where a vendor states neither clip length nor credits-per-generation, this page says so rather than guessing.
実際によく聞かれること
What is the cheapest AI video generator?
On the numbers each vendor publishes, Hailuo at about $0.096 a clip — though that uses its $7.99 promotional rate against a $14.99 list price. Kling is next at roughly $0.20 a 720p video. Pika is the cheapest way to get commercial-use video at all, because its free tier allows it.
Is there a genuinely free AI video generator for commercial use?
Pika’s free plan is the only one here that states both commercial use and watermark-free download, at 80 credits a month — roughly six 480p clips. Kling’s free tier explicitly forbids commercial use, and Runway’s watermarks output.
Why does FlowPix charge $69 for video?
Video generation is routed to sixteen third-party models — Veo, Kling, Seedance, Hailuo, Vidu — and the per-generation cost of those models is what sets the floor. It is genuinely expensive relative to a single-model tool, and if video is your main use case a dedicated vendor will cost less.
How should I compare AI video pricing?
Convert everything to cost per second at the resolution you actually need, then check three things the price hides: whether the clip length you want is available on that tier, whether output is watermarked, and whether the headline price is a first-month promotion. Those three change the ranking more often than the sticker price does.
