Hailuo vs Kling vs Veo (2026): Which AI Video Generator Is Actually Cheaper?

AI video pricing in September 2026 is the messiest category NotCheapAI covers, and it's not close. Every one of these three platforms — Hailuo (MiniMax), Kling AI (Kuaishou), and Google Veo — mixes subscription tiers, credit systems that convert to real seconds of video at different rates depending on model version and resolution, and separate per-second API pricing that often has no fixed public conversion rate back to the consumer credit system. We've converted everything we could to two comparable units: cost per generated second and cost per generated minute, with a clearly separate model for the failure/retry tax rather than pretending any of these tools nails a usable clip on the first attempt.

A note on precision: third-party pricing pages for Hailuo and Kling disagree with each other by as much as 30–50% on identical plan names, which is unusual even for this category. We've flagged every place that happens below rather than picking whichever number looked cleanest. Google's Vertex AI/Gemini API pricing for Veo, by contrast, is officially published and internally consistent.

Quick verdict

• Cheapest raw per-second API rate: Hailuo, at roughly $0.08–$0.10/second for 1080p output via third-party hosts — undercutting Kling's API rate and running at roughly a fifth of Veo 3.1 Standard's per-second cost.
• Best free tier for genuine experimentation: Kling, with 66 credits refreshed daily (no monthly commitment) versus Hailuo's more limited one-time free allocation.
• Best for guaranteed-usable output with synchronized audio: Veo 3.1 Standard, which is also the most expensive per second by a wide margin — you're paying for reliability and native dialogue/SFX generation, not just pixels.
• Best value at moderate volume with commercial rights: Kling Standard/Pro, once you calculate cost per accepted clip rather than cost per credit.

How each platform actually bills you

Hailuo (MiniMax)

Hailuo separates its web subscription tiers from its developer API, and MiniMax itself doesn't publish a clean credits-to-seconds conversion table — third-party trackers have had to reverse-engineer it from official plan prices and credit allotments.

Consumer subscriptions (reported figures — see caveat below):

Caveat: we found genuinely conflicting figures across sources for every paid tier in this table — differences large enough that they can't be explained by regional pricing alone. The lower end of each range comes from a source citing per-plan credit costs consistent with MiniMax's own published per-clip credit examples (e.g., a 6-second, 1080p Hailuo 2.3 Pro generation costs 127 credits); the higher end appears in several review-style sites without a cited primary source. Treat the low end of each range as the more defensible number and verify directly on hailuoai.com before budgeting.

Credit cost per video is itself model- and settings-dependent. Using MiniMax's more granular published figures for Hailuo 2.3 Pro:

Developer API: billed per second, scaling with resolution. Krea.ai publishes fixed USD API rates for Hailuo 02:

That works out to roughly $0.0175–$0.02/second at 512p, up to $0.0945/second at 1080p. Other third-party hosts (Atlas Cloud, Apiframe, PiAPI, fal.ai) quote flat per-second rates in the $0.04–$0.10/second range depending on resolution and whether you're paying pure pay-as-you-go or a subscription-plan rate — Apiframe's own comparison found its pay-as-you-go top-up rate was the most expensive of four providers tested, while its monthly-plan effective rate was the cheapest, meaning the "best" Hailuo API price depends heavily on your commitment level, not just which host you pick.

Kling AI (Kuaishou)

Kling's consumer pricing, like Hailuo's, has meaningful cross-source disagreement (Standard reported at both $10 and $6.99/month; Pro at both $37 and $25.99–$30; Premier at both $92 and $64.99–$75). We're presenting the range and flagging it rather than resolving it, since neither figure traces to an unambiguous primary source in our research.

The free tier is genuinely generous in daily terms (66 credits resets every 24 hours, no monthly cap), but it carries real restrictions beyond resolution: watermarks can't be removed, Professional Mode is capped at 3 trial generations, and Video Extension is capped at 2 uses. Community reporting (Reddit, cited across several trackers) consistently describes the free tier's daily allowance as impractical for anything beyond quick tests, partly because generations frequently need multiple attempts before producing usable motion.

API: Kling's official API sells prepaid resource-unit packages rather than flat pay-as-you-go pricing, starting around $9.80 for a small trial package. Per Kling's own model documentation, generation without audio runs roughly 6–8 credits/second (720p vs 1080p), climbing to 9–12 credits/second with native audio plus a small surcharge for voice control. Failed API generations don't consume credits — a meaningful difference from the consumer app, where a failed or discarded generation still burns the credit. Third-party trackers convert this to roughly $0.084–$0.168 per second of API-generated video.

A hidden cost worth flagging explicitly: several trackers note that newer Kling model versions (2.0 and beyond) consume meaningfully more credits per generation than older versions did — one source cites a 200% cost increase tied to a model upgrade. If you budgeted around an older model's credit economics, re-check your actual per-video credit burn after any Kling model update.

Google Veo (3.1)

Veo pricing runs through two entirely separate systems that don't share a common unit.

Consumer access (Gemini app / Flow, via Google AI subscriptions):

Google's "AI Credits" are a shared currency across image, video, and other generative features on a given plan — they are not a video-specific allowance, which makes isolating a true cost-per-video-clip figure inherently approximate on the consumer side.

Developer API (Vertex AI and the Gemini Developer API):

This is the cleanest, most internally consistent pricing table in this entire article — Google publishes it directly, and multiple independent trackers corroborate the same figures. An 8-second Veo 3.1 Standard clip with audio costs $3.20 via the API; the Fast tier drops that to $1.20.

Normalized cost comparison

Cost per generated second (API/developer rates, no subscription amortization)

Cost per generated minute (extrapolated from per-second rates)

Hailuo is the cheapest per-second option in the API market by a meaningful margin at every resolution we could verify. Veo is the most expensive, and deliberately so — Google is charging for a model that reliably produces native, lip-synced dialogue and layered sound effects in a single pass, a feature the other two don't match at the same level of consumer polish as of September 2026.

Generated footage vs usable footage: the retry/failure tax

None of these three platforms should be budgeted at their nominal per-second rate if you're planning real production work, because none of them reliably produce a usable clip on the first attempt. We're not going to invent a universal failure rate — nobody credible has published one, and it varies wildly by prompt complexity, motion demands, and how forgiving your use case is. Instead, here's what an 8-second 1080p clip costs under explicit, labeled retry scenarios, using the low end of each tool's per-second API range as the baseline:

Two things fall out of this table that matter more than the headline per-second rate:

1. At a 3-attempt failure rate, Hailuo and Kling remain closer to each other than either headline number suggests, while Veo 3.1 Standard's already-high per-second cost compounds fastest in absolute dollar terms.
2. Kling's API explicitly doesn't charge for failed generations (only completed ones), which — if accurate to your workflow — means the retry tax shown above overstates Kling's real cost relative to Hailuo and Veo, both of which appear to bill every generation attempt regardless of output quality, based on available documentation. This is a meaningful asymmetry worth confirming directly with each provider before committing a large batch budget.

On the consumer subscription side, the retry tax is partially absorbed by monthly credit allowances rather than hitting a per-clip invoice directly — but it still shows up as "how many usable videos did my $10–$92/month actually produce," which is consistently reported as lower than the plan's headline credit-to-video math implies, across all three platforms.

Hidden and easy-to-miss costs

Credit consumption drifts upward as models improve — your budget doesn't automatically adjust. Both Hailuo and Kling have shipped newer model versions during 2026 that consume more credits per generation than their predecessors did for a comparable clip (one tracker cites a 200% credit-cost increase tied to a single Kling model upgrade). If you costed out a workflow against last quarter's credit economics, re-check it against the current model's actual consumption before assuming your monthly plan still covers the volume you're planning.

Google's "AI Credits" are shared across features, not video-specific. A heavy week of image generation or Deep Research reports on the same Google AI plan can eat into the same credit pool that funds your Veo clips. Unlike Hailuo and Kling, where the credit allowance is dedicated to video (and, on some tiers, image) generation specifically, Google's model means video budgeting requires accounting for everything else you do on the plan too.

Free-tier outputs are frequently unusable for anything beyond a test. All three platforms cap free-tier resolution well below their paid-tier maximums (360–540p on Kling's free plan, 720p and 8-second clips on Veo's free Gemini access), and Kling's free tier additionally restricts Professional Mode and Video Extension to a handful of trial uses. Treat free-tier access as a way to evaluate a model's output style, not as a viable production tier for anything client-facing.

Watermarks are not optional or removable on Veo, regardless of plan or price paid. Google's SynthID marking is embedded at the model level, not the subscription level — even Ultra-tier, full-price Veo 3.1 Standard output carries it. If a project genuinely requires unmarked output, verify each platform's current watermarking policy before committing, since this varies meaningfully between Veo (always marked) and the other two (typically marked only on free/lower tiers).

Regional and reseller pricing can meaningfully undercut — or overcharge — the "official" rate. Hailuo's API in particular showed real price variation across third-party hosts (Apiframe, fal.ai, PiAPI, Atlas Cloud) for what is nominally the same underlying model. Shopping a single high-volume workload across two or three hosts before committing can be worth more than optimizing which of the three platforms you choose in the first place.

Native-audio economics: what sound actually costs

(Verified provider facts, with one important structural caveat.) Only Kling prices audio as a distinct, toggleable add-on to an otherwise identical generation. Hailuo 2.3 doesn't offer native audio generation at all, at any price. Veo bundles audio into the tier itself rather than metering it separately — there is no "Veo 3.1 Standard, silent" price to compare against "Veo 3.1 Standard, with audio," because audio generation is part of what defines the Standard and Fast tiers as distinct from the cheaper, silent Veo 3.1 Lite tier (roughly $0.05/second, no audio, lower fidelity — a genuinely different quality tier, not an audio toggle on the same model).

The honest reading of this table: Kling is the only one of the three where you can isolate "what does audio cost" as a single number, and the answer is roughly a 40–50% credit premium per second. Veo's audio-inclusive tiers cost 3–8x more per second than its silent Lite tier, but that comparison conflates audio with a genuine jump in resolution and motion quality — it would be misleading to call the entire gap an "audio surcharge." Hailuo simply isn't a contender if synchronized audio is a requirement, regardless of price.

Case study: Kling's model-version credit inflation

(Verified provider facts and independently corroborated user reporting, clearly separated below.)

Kling's pricing model has changed structurally, not just numerically, across model versions — this part is independently documented. Per a detailed API breakdown (Apiframe, cross-referenced against Kling's own model documentation): Kling 2.1, 2.1 Master, 2.5 Turbo Pro, and 2.6 all bill a flat credit cost per generation based on duration and mode — a 10-second Kling 2.6 clip with audio costs a flat 238 credits regardless of how the full duration is used. Kling 3.0, released February 2026, switched to pure per-second billing instead: a Pro-mode clip with audio costs 58 credits per second generated, meaning a 5-second clip runs 290 credits and a 15-second clip runs 870, with no volume discount at longer durations. Separately, within the 2.1 family, Kling 2.1 Master (the higher-quality-tuned variant) costs roughly 5.5x the credits of standard 2.1 for the same 5-second duration (238 credits vs. 43).

On top of that structural shift, a widely repeated user-reported figure — originating from Reddit discussion and cited across multiple independent trackers — claims Kling 2.0 launched at nearly 3x the per-generation cost of the preceding 1.6 model, with no advance notice to existing subscribers. In its original form, this claim traces back to the same Reddit thread across the trackers that cite it; it is not independently confirmed by several unrelated sources. Whether the exact multiple was 2x or 3x, the directional pattern is corroborated by the structural, officially-documented changes above: newer, higher-quality Kling model tiers consistently cost meaningfully more credits per generation than the tier they replaced, and at least one version transition (2.1 to 3.0) changed the entire billing unit from "per clip" to "per second," which is a more disruptive change to a subscriber's budget than a simple price increase would be.

Practical takeaway: if you're budgeting Kling against a subscription plan's advertised "X clips per month" figure, verify which model version that figure assumes. A plan sized around Kling 2.1's flat 43–153 credit range will run out dramatically faster against Kling 3.0's per-second billing at 58 credits/second.

Methodology: how the retry/failure-tax table was built

The retry-tax table earlier in this article is a NotCheapAI calculation, not a claim about real-world failure rates. It uses the lowest verified per-second API rate for each tool at 1080p, multiplies by 8 seconds for a baseline single-attempt clip, then multiplies that baseline by 1, 2, 3, and 5 to model workflows requiring that many attempts per accepted clip. These are scenarios for readers to compare with their own experience, not predictions that any tool fails at those rates. The calculation also does not account for Kling's documented policy of not charging for failed API generations. If applied in practice, that policy would make Kling's retry cost lower than the table implies relative to Hailuo and Veo, which appear to bill each attempt regardless of outcome based on available documentation. Treat the table as a simplified comparison, not a precise forecast.

Which provider makes economic sense for whom

Casual creators. Kling's free tier (66 credits/day, no monthly commitment) is the strongest genuinely-free option in this category, provided you can tolerate 360–540p output, watermarks, and no commercial use. For anyone wanting occasional 1080p output without falling into a video-specific subscription, Google AI Plus at $4.99/month bundles in Veo 3.1 Fast access alongside everything else in Google's ecosystem — likely the best per-dollar entry point if you're not planning high volume.

Social-media creators (regular short-form output, commercial use required). Kling Standard ($6.99–$10/month, 660 credits) or Hailuo Standard (similarly priced) both clear the commercial-use bar at the lowest published price points in this comparison. Kling's larger and more mature user base and documentation slightly favor it if you're choosing blind.

Professional creators. This is where the three genuinely diverge. If synchronized audio/dialogue is central to your output, Veo's API is the only one of the three built for it as a first-class, single-pass feature - worth the per-second premium. If audio isn't required and stylized/anime aesthetics fit your niche, Hailuo's per-second cost advantage compounds meaningfully at volume; several third-party benchmarks specifically flag Hailuo's anime/illustration strength as unmatched for price-to-quality in that style.

If these clips are part of a long-form channel workflow, our AI YouTube video cost guide models footage, narration and thumbnails together.

Agencies and high-volume production. Kling Premier/Ultra ($64.99–$180/month, 8,000–26,000 credits) offers the most credits-per-dollar at scale among the consumer-facing plans, provided your model-version credit costs stay stable rather than climbing on the next Kling update. For agencies that need contractual reliability, SynthID provenance, and Google ecosystem integration (YouTube, Workspace), Veo's Vertex AI tier remains the safer choice despite the per-second premium — you're buying predictability, not just pixels.

API/developer workloads specifically. Hailuo's per-second floor is the cheapest of the three at comparable resolution, but shop between hosts — Apiframe, fal.ai, PiAPI, and Atlas Cloud quote meaningfully different rates for the same underlying model, and subscription-plan rates on some hosts beat pure pay-as-you-go by roughly 2x at sufficient volume.

When does Hailuo actually beat Kling or Veo?

Based on the per-second and retry-adjusted numbers above: Hailuo wins on raw usable-video cost specifically when (a) native synchronized audio isn't required, (b) your resolution needs top out around 768p–1080p rather than demanding Veo's 4K tier, and (c) your workflow tolerates Hailuo's documented strength in stylized/anime content over live-action realism. Once you need native audio, Veo's single-pass reliability likely offsets its per-second premium by eliminating a separate audio-generation and syncing step entirely. Once you need the largest possible free allowance for testing before committing budget, Kling's daily-refreshing free credits beat Hailuo's one-time free allocation outright.

Amortized subscription cost per clip, by usage level

The per-second API tables above are the cleanest comparison, but most creators access these tools through a subscription, not raw API billing. Here's roughly what an 8-second clip costs when you amortize a monthly subscription price across a realistic number of clips actually produced (not the plan's theoretical maximum):

These figures assume most generations are accepted on a reasonable number of attempts and are meant as a planning baseline, not a guarantee — actual cost per clip depends heavily on how often you re-roll a generation before accepting it, which none of the three platforms publishes a rate for.

Frequently asked questions

Why do Hailuo and Kling pricing pages disagree so much between sources? Both platforms have gone through multiple pricing revisions in 2026, credit-cost-per-video changes tied to model updates (notably Kling 2.0+), and regional pricing variation that some trackers don't clearly separate from US pricing. We've presented ranges rather than single numbers wherever our sources genuinely conflicted.

Does Veo watermark its videos? Yes — every Veo output carries Google's SynthID invisible digital watermark, and this cannot be removed on any plan, consumer or API.

Is there a free way to use Veo? Yes, through the free tier of the Gemini app, but it's limited to Veo 2 (not the newer 3.1 model), capped at 720p and 8-second clips.

Which platform has the most generous free tier? Kling, by a clear margin — 66 credits refresh every 24 hours with no monthly cap, versus Hailuo's one-time 200-credit welcome allocation.

Do failed generations cost money? It depends on the platform and access method. Kling's official API explicitly does not charge for failed generations. Consumer-app failures across Kling, Hailuo, and Veo generally do consume your credit/quota allowance regardless of output quality, based on available documentation and user reporting — this is one of the most consistently cited frustrations across all three platforms' user communities.

Which tool is cheapest for a 30-second clip? At the API level, Hailuo, by cost per second. Factoring in a realistic 2–3 attempt retry rate, Hailuo and Kling land close enough to each other that the gap is smaller than headline per-second rates suggest, while Veo 3.1 Standard remains several times more expensive in absolute dollar terms for the same duration.

Can I get Veo's native audio on Kling or Hailuo? Not natively at the same level. Kling supports native audio generation at a higher credit cost (9–12 credits/second vs 6–8 without), but Veo's audio — including synchronized dialogue — is generally regarded as the most mature implementation of the three as of September 2026.

Do these tools offer annual billing discounts? Kling's plans show effective monthly savings on annual billing (e.g., Standard's $6.99–$10/month drops to roughly $6.60–$7.99/month effective). Hailuo's annual discount structure is less consistently documented across sources. Google's consumer AI plans do not currently publish an annual-billing discount.

What's the single most important hidden cost across all three platforms? The gap between a subscription's headline "videos per month" figure and the number of videos that survive first-attempt generation without needing a retry. Every platform's real-world credit consumption runs meaningfully higher than the marketing math implies, and none of the three publishes an honest failure rate — which is exactly why this article models scenarios instead of asserting one.

Pricing, credit systems, and model versions for all three platforms are unusually volatile in this category; figures in this piece reflect the most defensible interpretation of conflicting sources as of September 2026 and should be re-verified on each provider's official site before committing production budget.
