Kling AI Pricing [2026]: Runway $0.10 to $0.29/sec

Runway publishes the clearest price list of the three platforms in this comparison. Its Standard plan works out to about $0.29 per second of Gen-4.5 video, Max drops that to about $0.12 at monthly billing, and Max billed annually lands near $0.10. Kling AI and Google Veo do not offer a like-for-like figure that holds up on November 13, 2026. This article sets out what each vendor’s own pages show, what rests on a single report, and how to price a clip before you spend a credit.

The three product lines are all fresh. Kling 4.0, Veo 3.1 and Runway Gen-4.5 are the newest models on each maker’s own site as of November 12, 2026. Runway also sells Kling 4.0 and Veo 3.1 through its API next to its own model, so you can pay Runway for either rival. Its developer documentation describes one credit balance and one API key across several vendors’ models, which means any price comparison has to say which door you walk through.

We already compared the free tiers for photo animation in our free image-to-video comparison of Kling 4.0 and Veo 3.1. This piece covers the money side for text-to-video and mixed workflows: plans, credits, API rates and the cost of a finished clip. If you make intros, stingers, b-roll or short ads, that cost is the number that decides whether AI video fits your budget.

Everything below comes from vendor pages fetched on November 12 and 13, 2026 and from dated reports. Tables hold only figures that at least two sources agree on. Where a number rests on one report, the text says so and hedges it. Where no reliable number exists, the text says that too.

Kling AI Pricing vs Veo vs Runway at a Glance

Runway is the only one of the three with a verified, dated price ladder. Free costs $0 and gives 125 one-time credits. Standard costs $15 per month, Pro $35 and Max $95. Annual billing cuts those to $12, $28 and $76 per month, a 20% saving. Divide each plan’s credits by the Gen-4.5 rate on Runway’s pricing page and you get the effective cost per second: about $0.29, $0.19 and $0.12 on monthly billing, and about $0.23, $0.15 and $0.10 on annual billing.

Kling AI is harder to pin down. A pricing report dated November 12 lists Standard at $10, Pro at $37 and Premier from $92, with an Ultra+ tier at $619. That is a single report, and it does not give a single price per second for Kling 4.0 that you can compare directly.

Veo 3.1 is the least transparent for a creator who wants a rate card. Google’s DeepMind page describes what the model does and cites preference tests, but it prints no per-second price. One report from November 11 puts Veo 3.1 at $0.40 per second, and it does not say whether that is Google’s list price, one API configuration or a reseller’s rate. Treat it as a pointer, not a quote.

The takeaway for budgeting: use Runway’s numbers as your measuring stick, because they are the only ones you can check against a published plan. Then ask Kling and Google for the checkout price of the exact model, resolution and audio setting you plan to use. The sections below show how to do that math and where the gaps sit.

Which Models Are Current: Kling 4.0, Veo 3.1 and Gen-4.5

Compare the newest model of each line, because older names still turn up in price pages and reviews. The makers’ own sites list Kling 4.0 for Kling AI, Veo 3.1 for Google and Gen-4.5 for Runway. Luma’s site lists Ray 3.2 and Pika’s lists Pika 2.5, which matter later when we look at alternatives. Kling 3.0, Kling 3 Pro and Gen-4 are predecessors. Prices quoted for them should not be applied to the newer models.

The table below uses only what the makers’ pages and the dated research confirm. Cells that read “Not confirmed” mean the pages fetched on November 12 and 13 do not state the fact, so you should check the vendor’s checkout screen before you rely on it.

Two caveats shape the rest of this article. First, Google has not announced a newer Veo version in the pages we read, and its October 2026 AI roundup centred on Gemini 4 Argon and Carbon and the Genie 4 world model. Veo shows up inside Gemini 4 Argon, which uses it to turn scientific material into illustrated animation. That points to deeper Gemini integration, not a new Veo release. Second, Kling 4.0’s rollout is documented unevenly, which the next section covers.

A word on the spec gaps. Clip length, watermark rules and free-tier terms are the three facts creators ask about first, and they are also the three that vendors change most often. A watermark rule that applies to a free plan can vanish on the cheapest paid plan, and a maximum length can differ by model variant. That is why this table says “Not confirmed” instead of repeating a number from a review that may be a month old.

Kling AI Pricing: Plans, Credits and Conflicting Reports

Kling AI announced Kling 4.0 on September 30, 2026, with early access starting around September 28 and a wider rollout planned for October. The announcement said the model would first reach Ultra Yearly subscribers. A Kling 4.0 Flash variant also reportedly appeared in early access. Whether your account sees the model depends on your plan and region.

Subscription tiers: what the reports say

Kling’s consumer plans are not backed by a dated official credit table, so you cannot turn them into a per-second price. A November 12 report lists Standard at $10 for 660 credits, Pro at $37 for 3,000 credits, Premier from $92 for 8,000 credits (reaching $428 for 38,000) and Ultra+ at $619 for 57,000 credits. That report is a single source, so read it as a snapshot rather than a rate card.

The Chinese-language Kling site adds another wrinkle. It has shown membership promotions in recent weeks. Promotions of that kind change what you pay without changing the list price, and they differ by market. Before you compare Kling with Runway, check which storefront and which billing term you are actually looking at.

Kling’s own showcase pages are more consistent than its pricing coverage, and they matter because they show what the model is for. They list award-winning ads, a viral short film and a 135-minute feature whose visuals the studio says came entirely from Kling. Those examples appear later. For pricing, the useful lesson is that Kling targets long, story-driven output, and its cost depends on how many seconds you generate and how many takes you throw away.

Kling 4.0 API rates and the open question

A November 13 report puts official Kling 4.0 API pricing at roughly $0.157 per second at 720p and $0.2355 per second at 1080p, though the report does not cite a primary Kling source. Runway’s pages lean the same way. Runway Dev shows Kling 4.0 with a list price of $0.157 per second and a promotional price of $0.1256, and Runway’s own comparison reportedly lists $0.235 per second at 1080p. Those numbers agree with each other, which makes them plausible, but they describe Runway’s resale of Kling 4.0 and not necessarily Kling’s own API.

Current reporting also conflicts on whether Kling’s official 4.0 API is open yet. One result describes official prices, another says the API is not yet available. Kling runs a separate developer portal, and its Open Platform documentation is the place to confirm access before you build a pipeline on it. Until you see a dated price on that portal, budget with the Runway-resold figure and treat it as an upper bound for planning.

Kling’s announcement, as summarized in the research, lists native 30-second generation, 10-bit HDR, Omni Reference, multiple keyframes and stronger storytelling controls. If those features work as described, they change the price math in your favor for long scenes, because one 30-second generation replaces several stitched five-second clips and the continuity fixes between them. That is a hypothesis to test with your own prompts, not a result anyone has published.

Veo 3.1 Pricing: One Reported Rate and Several Unknowns

Google’s Veo 3.1 page covers capabilities, not prices. It lists text-to-video, image-to-video and text-to-audio+video generation, plus realistic physics. It also names four editing features: ingredients to video, Scene Extension, First and Last Frame, and Object Insertion. There is no per-second line anywhere on it. The only Google page in our research that mentions a consumer price is a student offer for Google AI Plus, which auto-renews at $6.99 per month after a free year for eligible Canadian students. The Google announcement does not state any Veo quota, credit count or resolution limit.

That leaves the $0.40 per second report from November 11. Without knowing the resolution, whether audio was on, or whether the seller was Google or a reseller, the figure cannot anchor a budget. Runway Dev’s model guides, for example, advertise the official Google Veo 3.1 API with variants that include or omit audio, but we found no complete Veo price table there. A single number cannot cover two audio modes and several resolutions.

One operational note for developers. A report dated October 22, 2026 says Google discontinued Veo 3.1 preview model identifiers in the Gemini API. If you have scripts or automations that still call a preview ID, check them against Google’s current model list. A failed call costs you nothing in credits, but a silent fallback to a different model could change both the look and the bill of a whole batch.

The practical advice is simple. Pick the exact Veo 3.1 variant, the resolution and the audio setting you need, then price one test clip at the checkout or the API console you will really use. Multiply by the number of seconds in your project. Do not carry a per-second figure from a blog post into a quote for a client.

Runway Pricing: Plans, Credits and Seconds Per Month

Runway’s pricing page ties every plan to seconds of Gen-4.5 output, which is why this platform is the easiest to cost. Standard’s 625 monthly credits equal 52 seconds of Gen-4.5, Pro’s 2,250 credits equal 187 seconds, and Max’s 9,500 credits equal 791 seconds. That works out to roughly 12 credits per Gen-4.5 second. The same page converts credits into other models, such as 104 seconds of Gen-4 Turbo on Standard and 1,900 seconds on Max.

The annual savings on Runway’s page are $36 per year for Standard, $84 for Pro and $228 for Max. Max also adds faster high-volume generation and rolls over unused credits, which matters if your output swings between heavy launch weeks and quiet ones. The free allowance of 125 credits is one-time, so it works as a trial, not a monthly allowance. At 12 credits per second it covers roughly 10 seconds of Gen-4.5.

Look at how the price per credit falls as you climb. On monthly billing, Standard is $15 for 625 credits, Pro is $35 for 2,250 credits and Max is $95 for 9,500 credits, so each credit gets cheaper at every step. That explains the whole ladder: each jump costs more in dollars but buys far more credits. If you hit Standard’s ceiling twice in a row, Pro is almost always the cheaper way to keep working.

Unlimited becomes Max on November 30

Runway has said that its legacy Unlimited plan will transition to Max on November 30, 2026. Eligible subscribers stay on Unlimited until then. The legacy plan gave 2,250 monthly credits plus Explore Mode, which allowed unlimited generations at a relaxed rate. According to Runway’s help centre, monthly Unlimited subscribers move automatically to Max at the same $95 per month unless they cancel. If you were counting on relaxed-rate generations to cover retries, that safety net is scheduled to disappear. Max gives 9,500 credits instead, so plan for a hard credit ceiling.

Runway Dev: The Per-Second Marketplace for Kling, Veo and Wan

Runway Dev is where the platform’s role changes. Over the last three months, Runway’s documented scope widened from a single-model generator into a multi-provider catalog and API layer. The catalog includes its own Gen-4.5 and Aleph 2.0, plus Kling 4.0, Seedance 2.5, Wan 3.0, MiniMax H3 and Google’s Veo 3.1. Runway reportedly bills at $0.01 per credit on Dev, before volume discounts, cashback or enterprise pricing. That makes per-second comparisons simple, because a model’s price in credits is its price in cents.

Two Dev prices are confirmed by more than one source. Wan 3.0 costs $0.20 per second, and Seedance 2.5 costs $0.68 per second, with the quoted prices generally referring to 1080p where a resolution is given. Runway’s dated example puts a 10-second Seedance 2.5 clip at about $6.80 before discounts. Wan 3.0 Prime appears at three rates of $0.068, $0.14 and $0.28 per second. Reports also list Seedance 2.0 at $0.14 per second at 480p, rising to $1.50 at 4K, and MiniMax H3 at $0.10 per second at 768p and $0.15 at 2K, but each of those figures has only one source.

The Dev model also changes how you think about retries. Runway says workflows add no separate fee, and a run costs the sum of the paid model nodes inside it. So a chain that generates with one model and edits with another is billed per node, which is easy to audit if you log each call. Runway also advertises a 25% discount on Kling 4.0 generations until November 30 on its app pricing page, while another banner on the same site says 20%. The figures disagree, so check the discount on your own checkout screen before you plan around it.

On the app side, the pricing page shows a credit cost for a five-second Kling 4.0 clip next to a promotional cost. I read the figures as 118 credits at list and 89 credits with the 25% discount, though the page text is terse. At about 12 credits per Gen-4.5 second, a five-second Gen-4.5 clip costs about 60 credits, so Kling 4.0 on Runway looks to cost roughly twice as much per second as Gen-4.5. That is an inference from page text, not a quoted ratio, so confirm it before you commit a month’s credits.

Cost Per Finished Clip: The Math at 5 to 60 Seconds

Per-second rates feel abstract until you multiply them by a real clip. The table uses the verified effective rates for Gen-4.5 on Runway plans, plus the two confirmed Runway Dev prices for Wan 3.0 and Seedance 2.5. All figures are single-pass generation costs, so they assume every clip is usable. The next sections add retries.

Read the table by column. A creator who ships one 10-second intro per week spends about $2.90 a week on Standard if every clip works, which uses 40 of the plan’s 52 monthly seconds. That ceiling is the real constraint. Standard’s 52 seconds hold about ten five-second clips, Pro’s 187 hold about 37, and Max’s 791 hold about 158.

Annual billing matters most at the top. Moving Max from monthly to annual saves $228 a year and trims the effective rate from about $0.12 to about $0.10, a drop of roughly 17%. On Standard, annual billing saves $36 a year, which is a smaller sum but still lowers the rate from about $0.29 to about $0.23. If you are unsure you will keep generating video through the next winter, pay monthly for the first two months and switch to annual once you know your seconds per month.

The table cannot show Kling 4.0 or Veo 3.1 rates, because no source here confirms them. If the reported Kling 4.0 API range of $0.157 to $0.2355 per second holds, a 10-second clip would cost about $1.57 at 720p and somewhat more at 1080p. If the reported Veo rate of $0.40 per second applies to your setup, a 10-second clip would cost about $4.00. Both are single-source numbers, so use them only to sanity-check a quote.

Quality Benchmarks: What Is Published and Who Ran It

Cost per second says nothing about whether a clip is worth keeping. The public evidence on quality is thin and mostly vendor-run. Google’s DeepMind page is the only one of the three makers that publishes preference tests, and each result is labelled as last updated in October 2025. That makes them a year old and tied to the Veo 3.1 launch, not to anything shipped in the last month.

Three things limit how far you should lean on that table. The datasets come from outside Google, since MovieGenBench was released by Meta and VBench is a public benchmark, but the raters and the model selection come from Google. The tests are about a year old. And neither Kling nor Runway publishes a comparable head-to-head on the pages we read for Kling 4.0 or Gen-4.5. No independent, dated November 2026 benchmark that ranks all three models turned up in our research.

Google also says Veo’s ingredients to video, Scene Extension, First and Last Frame and Object Insertion features reached leading results in head-to-head human-rater comparisons on internal benchmarks. Internal means you cannot inspect the prompts. Kling’s side of the story is the feature list in its September 30 announcement. Those are feature claims, not scored tests. They tell you what to try, not which model wins.

So the honest benchmark for your channel is your own prompt set. Write five prompts that mirror your real work, such as a logo reveal, a product shot, a b-roll cutaway, a text-heavy title and a fast action beat. Run each through two platforms, count how many takes you needed before one was usable, and price that. A model that costs 30% less per second but needs three takes instead of one is the more expensive model.

Hidden Costs: Retries, Resolution Tiers and Audio

A rate card prices the clips you keep and the clips you delete at the same rate. The effective cost of a usable second is the rate multiplied by the number of takes, divided by the number you keep. As an illustration only, assume you keep one clip in three. A Gen-4.5 second at the Max monthly rate of about $0.12 then costs about $0.36 per usable second. Your keep rate will differ with prompt skill and subject, so measure your own before you trust any figure here.

Resolution is the second multiplier. Runway Dev’s reported prices for Seedance 2.0 climb from $0.14 per second at 480p to $1.50 at 4K, a factor of more than ten. Kling’s reported API range runs from about $0.157 at 720p to about $0.2355 at 1080p, a rise of roughly 50%. Whatever the exact figures, the pattern holds across vendors. The same prompt costs very different amounts depending on the output tier, so draft at a low tier and render the final take at the high one.

Audio is the third. Runway Dev lists Veo 3.1 variants with and without audio. If you add music or voice in your editor anyway, pick the video-only variant. If you need lip-sync or sound effects aligned to motion, native audio can save an editing pass, and Google’s own page says Veo 3.1 leads on audio synchronization in its audio-subset tests. Runway’s catalog also lists Gemini Omni 1.1 Flash, which it describes as Google’s multimodal video model with native audio.

Plan structure is the fourth. Credits that expire punish bursty work, and credits that roll over reward it. Runway’s Max plan rolls unused credits over, and the Unlimited plan’s relaxed-rate mode ends on November 30. Kling’s tiers are credit-based, but without a defined clip length or resolution a tier’s credits cannot be converted into seconds. Before you pay, write down seconds per month, resolution, audio need and retry rate. Those four numbers decide which plan fits.

Real-World Examples: How Creators and Studios Pay for AI Video

The examples below mix vendor-reported projects with worked cost scenarios. Where a project comes from a vendor’s showcase, the claim is the vendor’s own and the article attributes it that way.

1. A weekly 10-second channel intro on Runway Standard. At about $0.29 per second, one clip costs about $2.90 and uses 10 of the plan’s 52 monthly seconds. Four weekly intros would leave only 12 seconds for retries, so a weekly uploader would likely outgrow Standard within a month.
2. The same intro on Runway Max billed annually. At about $0.10 per second it costs about $1.00 per clip and uses 10 of 791 monthly seconds. The plan costs $76 a month either way, so the saving only appears if you use the seconds.
3. A 10-second b-roll cutaway through Wan 3.0 or Seedance 2.5 on Runway Dev. Wan 3.0 at $0.20 per second costs $2.00, and Seedance 2.5 at $0.68 per second costs $6.80 in Runway’s dated example. Runway lists Seedance 2.5 as multi-reference video up to 30 seconds, which is the reason to pay more.
4. Cannes Lions 2026 ads. Kling’s showcase lists an ad by Argentine studio Purga Films, made entirely with Kling AI, that won Bronze in the Classic Film category. It also lists a Sebastian Strasser and Lipstick April Fools’ Day ad for The RealReal that won one Silver and one Bronze. Both are Kling’s claims about its tool, and neither includes production costs.
5. A 135-minute feature. Kling says Fountain 0 and Kling AI co-produced a film directed by Ash Koosha with all 135 minutes of visuals generated by Kling. For scale, Runway Dev lists Gen-4.5 at $0.12 per second, so even a single pass over a film that long would add up quickly, and real projects generate many takes per usable shot. This is a scale illustration, not a Kling price.
6. Music videos. Kling’s showcase credits Kling AI with the debut MV for the virtual idol Wu Aihua, made with Chaocreate and Warner Music China, which it says passed 11.2 million views, and with a felt-animation MV for the group TNT. Music video work is the case where audio and long continuity matter most.
7. Studios building on Veo 3.1. Google lists Promise Studios using Veo 3.1 inside its MUSE Platform for storyboarding and previsualization, Volley using it for cinematics and generated assets in the RPG Wit’s End, and OpusClip using it inside Agent Opus for promotional videos aimed at small businesses.

The pattern across them is consistent. Short, repeatable assets, such as intros and cutaways, fit a metered plan where you can predict seconds. Large narrative projects need either a high tier or an enterprise deal, and Runway’s news page advertises up to two months of usage free to enterprises that sign. That is a negotiation point if you are budgeting a series, not a consumer perk.

Use-Case Recommendations: Which Platform for Which Job

Match the platform to the kind of clip, not to the brand. The recommendations below follow the numbers above and flag what remains unverified.

• Weekly YouTube intro or outro stinger (5 to 10 seconds). Runway Pro. Its 187 monthly seconds fit about 18 ten-second takes at roughly $0.19 per second. Standard’s 52 seconds run out fast once you retry.
• Stream starting-soon loop or overlay motion. Wan 3.0 on Runway Dev at $0.20 per second, or Max if you also want Gen-4.5. A 10-second loop costs about $2.00 per pass on Wan 3.0, and you pay only for what you generate.
• Logo reveal with a brand-safe look. Test on Gen-4.5 first because the cost is predictable. If you need precise edits to an existing shot, Runway lists Aleph 2.0 for video editing. Kling 4.0’s Omni Reference, per its announcement, is also aimed at holding a reference look.
• Dialogue-led or sound-heavy clips. Veo 3.1, because Google’s page claims the best audio synchronization in its audio tests and the model generates sound with the video. Price a test clip first, since no rate card is confirmed.
• Long continuity, such as a music video or a multi-shot story. Kling 4.0, based on its announced 30-second native generation, multiple keyframes and storytelling controls. Confirm access on your plan, because the first rollout targeted Ultra Yearly subscribers.
• A studio testing several models. Runway Dev, because one credit balance reaches Kling 4.0, Veo 3.1, Seedance 2.5 and Wan 3.0, and every call is billed per second. You trade a possible markup for a single invoice.

If you only need a fixed-length opener and your budget is tight, remember that a template-based maker prices differently from any of these. It charges per export, not per generated second, and it gives you the same result every time. For a broader view of where each generator sits, see our pillar page on AI video generators.

Migration Guide: Moving Between Platforms Without Wasting Credits

Switching platforms costs more than the subscription fee. You lose unused credits, you retune prompts, and you risk a style shift mid-series. Use this order to keep the damage small.

1. Log last month’s output. Count the seconds you generated, the seconds you kept, and the resolution and audio setting of each. Without those numbers you are guessing at a plan size.
2. Compute your keep rate. Divide kept seconds by generated seconds. Use that figure to scale every rate in the cost table.
3. Check your expiry rules. Runway Max rolls unused credits over. If your current plan expires credits monthly, spend them down before you leave.
4. If you are on Runway Unlimited, decide before November 30. The plan moves to Max at the same $95 per month unless you cancel, and Explore Mode’s relaxed-rate generations end. Cancel, downgrade or accept Max, but do not drift into it.
5. Run the same five prompts on the new platform. Use identical wording, the same reference images and the same duration. Record takes needed and cost per kept second.
6. Update model IDs in any scripts. A report dated October 22 says Veo 3.1 preview identifiers were discontinued in the Gemini API. Replace them with current IDs and run one test call before a batch.
7. Decide direct or resold. Kling 4.0 and Veo 3.1 are both reachable through Runway. Buying direct may carry lower rates or earlier features, while buying through Runway gives one balance. Compare the checkout price for the same clip.
8. Keep the old plan for one cycle. Run a project on both for a month before you cancel, so a surprise quality gap does not strand a deadline.

One more tip on file handling. Whatever platform you pick, export or download each approved clip into your own folder the same day. Credit systems, plan changes and model retirements all happen on the vendor’s schedule, and your edit should not depend on a hosted asset.

Pros and Cons of Each Platform

Kling AI (Kling 4.0)

• Pros: newest model on Kling’s own site, announced capabilities aimed at long and story-driven work, and a showcase of award-winning projects. It is also resold through Runway if you want one invoice.
• Cons: plan prices conflict between reports, no dated per-second price on Kling’s own pages, unclear API availability and unconfirmed free tier and watermark rules.

Google Veo 3.1

• Pros: native audio generated with the video, a strong set of editing features, and Google’s published preference tests. Studios are already building on it.
• Cons: no confirmed rate card, tests that are a year old, preview identifiers reportedly retired in the Gemini API, and no announced successor to plan around.

Runway (Gen-4.5 and Runway Dev)

• Pros: the only verified price ladder, seconds per plan printed on the pricing page, annual discounts of 20%, and rollover on Max. One balance also reaches rival models.
• Cons: Standard’s 52 seconds are tight, Unlimited’s relaxed mode ends November 30, and prices for resold models may differ from the maker’s own.

Luma and Pika sit outside this three-way comparison but belong on a shortlist. The makers’ sites list Luma with Ray 3.2 and Pika with Pika 2.5 as their newest models. We found no verified per-second rates for either, so they are not priced here.

Verdict: Which Platform Costs Less Per Usable Second

On verified prices, Runway wins the budgeting contest by default. Max billed annually gives Gen-4.5 at about $0.10 per second, Pro billed monthly gives it at about $0.19, and Standard at about $0.29 suits only light use. Wan 3.0 at $0.20 per second on Runway Dev is the cheapest confirmed third-party option, and Seedance 2.5 at $0.68 per second is the premium end. No source here confirms a lower per-second price for Kling 4.0 or Veo 3.1.

That does not make Runway the best model for every job. Kling 4.0 and Veo 3.1 may deliver clips you cannot get from Gen-4.5, and a cheaper second that you discard is a wasted second. If the reported Kling 4.0 API rates of $0.157 and $0.2355 per second hold, Kling sits below Runway’s Standard plan at both resolutions. If the reported $0.40 for Veo 3.1 holds, Veo sits above Runway’s Standard plan per second, which is a fair trade only when you need its audio or editing tools.

Here is the decision in four lines. Weekly short assets: Runway Pro, and move to Max annual once you pass Pro’s 187 seconds a month. Dialogue and sound: price Veo 3.1 at checkout, and use it if the audio saves an editing pass. Long, story-driven work: test Kling 4.0 on a plan that actually unlocks it. Mixed testing across models: use Runway Dev and read the invoice per call.

Two dates to put in your calendar. November 30, 2026 ends Runway’s Unlimited plan and the Kling 4.0 discount on Runway’s pricing page. Revisit your plan right after that date with your real seconds-per-month figure in hand. Until Kling and Google publish a dated per-second price for their newest models, any article that gives you a single winning number is guessing.

Questions creators ask

Is Kling AI free to use?

The pages we fetched do not confirm a current Kling free tier or its watermark rules, so check the sign-up screen before you plan around one. Runway’s Free plan does give 125 one-time credits, roughly 10 seconds of Gen-4.5.

How much does Kling 4.0 cost per second?

No dated Kling page in our research prints a per-second price. Reports and Runway’s resale listing suggest a range that rises with resolution, but treat any figure as unconfirmed until you see it at checkout or on Kling’s developer portal.

How much does Veo 3.1 cost per second?

Google’s Veo page does not state a price. One November report gives a single rate without saying which resolution, audio setting or seller it applies to, so price a test clip in the product you will actually use.

Which platform is cheapest per second?

Among confirmed Runway plan figures, Max billed annually at about $0.10 per second for Gen-4.5 is the lowest, followed by Pro annual at about $0.15. Runway Dev lists Wan 3.0 at $0.20 per second and Wan 3.0 Prime from $0.068 per second, so cheaper per-second options exist outside the plans. The comparison is not like-for-like, because the models, plans and billing methods differ.

What happens to Runway’s Unlimited plan?

Runway says Unlimited transitions to Max on November 30, 2026. Max includes 9,500 monthly credits and rollover of unused credits, while the legacy plan’s relaxed-rate Explore Mode is scheduled to end.

Can I use Kling 4.0 and Veo 3.1 inside Runway?

Runway’s pages list Kling 4.0 and advertise access to the official Google Veo 3.1 API through Runway Dev, with models billed from one credit balance. Check that your plan includes them, since catalogs differ between the app and the API.

Do unused credits roll over?

On Runway, Max rolls unused credits over. The pages we read do not confirm rollover for the other Runway plans, Kling or Google, so read each vendor’s terms before you buy a large allowance.

Is AI video cheaper than a template-based intro maker?

For a fixed, repeatable intro, usually not. A template export costs the same each time, while AI video charges per generated second and per retry. AI video earns its price when you need shots a template cannot produce.
