The Best AI Video Generator
Google Flow, running Gemini Omni Flash, is the best AI video generator for most people: free daily credits, 10-second clips with sound, editing by chat and a top-ten ranking in blind votes. Kling makes the longest clips, and Pika is the cheapest way into several top-ranked models.
A free daily allowance, cheap paid plans, native audio and editing by chat, with a model that ranks near the top in blind votes and an invisible SynthID watermark on every clip.
Adobe’s own video model is trained on licensed and public-domain content, its Content Credentials label AI output, and partner models from Google, Kling, Runway and Luma sit in the same app.
The Research Score rates each product on its own merits. Our picks also weigh price and who the product is for, so a pick can rank above a higher-scoring product. How we score
AI video generators turn a text prompt or a still image into a short clip, usually somewhere between 5 and 15 seconds long, and the best ones now generate matching sound, dialogue and music in the same pass. The models change every few weeks, so the useful questions aren’t just “which looks best?” but also how long a clip can be, what resolution you get, whether the free tier is usable, whether you’re allowed to use the result commercially and whether it’s marked as AI.
For most people, Google Flow is the best place to start. It runs Gemini Omni Flash, which ranked in the top ten for text-to-video and fourth for image-to-video on Artificial Analysis’s blind-vote leaderboards at the time of research. Everyone gets 50 free Flow credits a day, enough for a few 10-second clips, and Google AI Plus costs $4.99 a month. Kling is our pick for longer shots, Pika is the budget way into several top-ranked third-party models, Runway is the pro toolkit, and Adobe Firefly is the cautious choice for commercial work.

Why you should trust us
We considered 15 AI video generators and models for this guide. We read their official pricing pages, help-center articles, terms and privacy policies, company announcements, and the independent Artificial Analysis text-to-video and image-to-video leaderboards, where validated evaluators vote blind between two clips made from the same prompt. Every pick is scored with our published Research Score. We did not generate videos ourselves for this guide; quality claims come from the leaderboards and the companies we name.
Who this is for
This guide is for anyone who wants to turn a prompt or a photo into a short, original video clip: social posts, B-roll, product shots, music-video scenes, storyboards or just fun. If you want a talking presenter, a full-length YouTube video or a tool that cuts your own footage into Shorts, that’s a different kind of tool; see our guide to the best AI video generator for YouTube, which covers HeyGen, Descript and OpusClip. For still images, see the best AI image generator.
How we picked
We looked for generators that do well on these points:
Output quality, judged by Artificial Analysis’s blind-vote leaderboards where a model is listed, and otherwise by published specs.
Clip length and resolution per generation, including upscaling options.
Native audio: whether dialogue, sound effects and ambience are generated with the picture.
Free tier and real cost: credits per clip, watermarks on free output and whether introductory prices hide the renewal price.
Commercial rights: whether the plan you can afford lets you use the result in paid or client work.
Labeling and provenance: invisible watermarks such as Google’s SynthID, Adobe’s Content Credentials, and visible watermarks on free plans.
Privacy: whether your prompts and uploads train the company’s models, and whether you can opt out.
Candidates we considered: Google Flow (Gemini Omni Flash), Kling, Pika, Runway, Adobe Firefly, Hailuo (MiniMax H3), Dreamina (ByteDance Seedance 2.5), Luma, Alibaba’s Wan 3.0, HeyGen Video 1, Grok Imagine Video, Utopai X, Black Forest Labs’ FLUX 3 video models, Google Veo 3.1 and OpenAI’s Sora.

Google Flow (Gemini Omni Flash)
7.8/10
A free daily allowance, cheap paid plans, native audio and editing by chat, with a model that ranks near the top in blind votes and an invisible SynthID watermark on every clip.
Gemini Omni Flash, which Google introduced at I/O 2026, generates video from a mix of text, images, audio and video, and lets you edit a clip by describing the change in conversation. It competes in Artificial Analysis’s with-audio category, so sound comes with the picture. Flow is Google’s creative studio for this work, and Google says Omni is rolling out there and in the Gemini app to Google AI Plus, Pro and Ultra subscribers globally. Flow’s credit table lists clips of 4 to 10 seconds, plus a 40-credit option for editing uploaded or generated videos.
On quality, the evidence is good rather than unbeatable. On Artificial Analysis’s text-to-video leaderboard, where evaluators vote blind between two clips made from the same prompt, Gemini Omni Flash 1.1 ranked 10th with audio when we checked. On the image-to-video board it ranked fourth with audio, and the leaderboard’s FAQ lists it first in the silent image-to-video category. Google’s older Veo 3.1 sits at 21st.
What makes Flow our top pick is the price of entry. Google’s help center says everyone gets 50 Flow credits a day, with or without a subscription. An Omni clip at 720p costs 7 credits for 4 seconds and 15 credits for 10 seconds, and a 360p draft costs about half that, so you can try ideas for free every day. Google AI Plus ($4.99 a month) adds 200 monthly credits and Pro ($19.99) adds 1,000, and subscribers get free 1080p upscaling. The same model also came to YouTube Shorts and the YouTube Create app at no cost, according to Google.
Flaws but not dealbreakers
Ten seconds per clip is shorter than Kling’s newest model, so longer scenes mean extending or stitching clips. Free users can’t upscale to 1080p, unused credits don’t roll over, and Google warns that video generation may be unavailable for free users between roughly 2 p.m. and 5 p.m. UTC. 4K upscaling is limited to Ultra subscribers (from $99.99 a month).
Every Omni video includes SynthID, Google’s invisible watermark, which you can check in the Gemini app, Chrome and Google Search. That’s good for transparency but means your footage can be identified as AI. We didn’t find a separate commercial license for Flow on the pages we checked, so read Google’s terms before client work.
Flow’s privacy notice says Google uses your prompts, uploads and outputs to improve its products and models unless you turn off “Help improve Flow.” Human reviewers see a sample, disconnected from your account, and reviewed items are kept for up to 18 months even after you delete them.
Who it’s for
Anyone who wants good-looking clips with sound without a dedicated video subscription, especially if they already pay for Google AI.
Who should skip it
You need clips longer than 10 seconds in one generation, or you won't accept Google using your Flow data to improve its models unless you switch it off.
Pros
50 free Flow credits a day; a 10-second 720p clip costs 15
Ranked 10th for text-to-video and 4th for image-to-video (with audio) on Artificial Analysis
Sound with the picture, editing by chat and free 1080p upscaling for subscribers
Every Omni video carries Google's invisible SynthID watermark
Cons
Clips top out at 10 seconds
Free users can't upscale, and video generation may pause at peak hours
Reviewed data is kept up to 18 months, even after you delete it

Kling
6.2/10
Kling 4.0 generates up to 30 seconds in one pass, and the Kling 3.0 series offers native 4K output with dialogue, ambience and lip movement.
Kling, from Kuaishou, is the generator to pick when 10 seconds isn’t enough. Kuaishou says Kling 4.0 officially launched on October 15, 2026, with “native generation of up to 30 seconds in a single pass,” steadier motion in fast action and complex camera moves, and an Omni Reference feature that accepts up to 15 reference assets and 10 keyframes. That last part matters if you need the same character or product to look consistent across shots.
The Kling VIDEO 3.0 series, according to Kling’s own credit guide, makes clips from 3 to 15 seconds, generates dialogue, ambience, sound effects and matching lip movement, and offers native 4K output at 30 credits per second. Paid plans run from Standard (660 credits a month) through Pro (3,000), Premier (8,000) and Ultra (26,000); they add commercial use, 1080p generation and removal of Kling’s brand watermark. Kling 4.0 is also available inside Runway if you prefer that app.
Flaws but not dealbreakers
Kling’s quality evidence is weaker than its specs. On Artificial Analysis’s text-to-video board, Kling 3.0 Omni 1080p (Pro) ranked 17th and Kling 3.0 1080p (Pro) 18th; the leaderboard uses the latter as its fixed reference point. Kling 4.0 wasn’t on the board when we checked. Kling’s guide also lists discounted first-subscription prices next to higher renewal prices, so check the membership page for what you’ll pay after month one.
The free Basic plan has no monthly credits, and Kling’s guide says its output “is not for commercial use.” The privacy policy doesn’t say whether your uploads train Kling’s models, offers no opt-out for that, names no security certifications and says data is stored on servers in Singapore.
Who it’s for
Creators who need longer continuous shots, 4K output or many reference images for consistent characters.
Who should skip it
You want a free tier you can use commercially, or you care most about blind-vote rankings.
Pros
Kling 4.0: up to 30 seconds in a single pass, according to Kuaishou
Up to 15 reference assets and 10 keyframes in Kling 4.0
Native 4K output and native audio in the Kling 3.0 series
Cons
Free Basic plan is not for commercial use and has no monthly credits
Kling 3.0 ranked only 17th–18th on Artificial Analysis; 4.0 not yet ranked
Thin privacy policy with no training opt-out

P
Pika
6.5/10
One subscription from $8 a month covers Pika’s own models plus MiniMax H3, Seedance 2.5, Wan 3.0 and Gemini Omni Flash, with no watermark.
Pika used to be known mainly for its own effects-heavy models. Today its pricing page reads like a model menu: every plan includes Pika 2.5, Pikaframes and Pika’s speech, music and sound-effect models, plus third-party video models including Seedance 2.5, MiniMax H3, Wan 3.0 and Gemini Omni 1.1 Flash. Those are some of the highest-ranked models on Artificial Analysis’s board: Wan 3.0 ranked first for text-to-video with audio when we checked, MiniMax H3 third and Seedance 2.5 fifth.
Starter costs $10 a month, or $8 a month billed annually, for 900 credits, and includes commercial use. Pika’s pricing page lists no watermark on any plan. Extra credits cost 60 per dollar on every plan and last a year.
Flaws but not dealbreakers
The free plan includes no monthly credits; you have to buy credit packs, and free output carries no commercial license. The pricing page lists 720p for the partner video models it names, so if you need 1080p or 4K, check each model’s settings first.
Privacy is the weak spot. Pika’s policy says it may use the content you submit, including inputs and outputs, to improve its AI models, and it describes no opt-out for that. It also shares identifiers and browsing activity with advertising partners, which you can stop through “Your Privacy Choices” or a Global Privacy Control signal.
Who it’s for
Hobbyists and small creators who want to try the highest-ranked models without paying for each one.
Who should skip it
You care about privacy; Pika may use your inputs and outputs to improve its models and offers no training opt-out.
Pros
Starter $10/month or $8/month billed annually, with commercial use
Includes MiniMax H3, Seedance 2.5, Wan 3.0 and Gemini Omni 1.1 Flash
No watermark on any plan, according to its pricing page
Cons
Free plan has no monthly credits and no commercial license
Pricing page lists 720p for the partner video models it names
Shares some data with ad partners unless you opt out

R
Runway
7.3/10
Runway’s Gen-4.5 plus third-party models such as Kling 4.0 and Seedance 2.5, editing tools and 4K upscaling, with commercial rights on every plan.
Runway is less a single model than a production suite. Standard ($15 a month, or $12 billed annually) gives you 625 credits a month, access to all of Runway’s video and image models, including its own Gen-4.5, Kling 4.0 and Nano Banana Pro, plus 4K upscaling and no watermarks. Pro ($35, or $28 annually) adds Seedance 2.5, unlimited Topaz AI upscaling and 2,250 credits. Its price list also includes Aleph 2.0 and Seedance 2.0 Pro.
Runway’s help center is unusually clear about rights: content you create is yours to use “without any non-commercial restrictions,” as between you and Runway, and you don’t have to credit Runway on YouTube, social media or at film festivals. The help article doesn’t limit this to paid plans.
Flaws but not dealbreakers
Gen-4.5 costs 12 credits per second, so Standard’s 625 credits equal just 52 seconds of it a month and Pro’s 2,250 equal 187 seconds. Credits on Standard and Pro don’t roll over. Runway’s own models don’t appear on Artificial Analysis’s text-to-video leaderboard, so we couldn’t compare Gen-4.5’s quality directly with Google’s or Kling’s.
Runway’s privacy policy doesn’t say whether it trains on your content and describes no training opt-out. It says disclosures to advertising and analytics partners may count as a “sale” or “sharing” under state laws, which you can opt out of. No security certifications are named in the policy.
Who it’s for
Filmmakers, agencies and editors who want generation and editing tools in one place.
Who should skip it
You only need a few clips a month; credits go quickly.
Pros
Commercial use with no attribution required, per Runway's help center
Includes Kling 4.0 and Gen-4.5; Pro adds Seedance 2.5 and Topaz upscaling
No watermarks on paid plans; 4K upscaling from Standard
Cons
Standard's 625 credits equal only 52 seconds of Gen-4.5
Runway's own models aren't on Artificial Analysis's leaderboard
Credits don't roll over on Standard and Pro

AF
Adobe Firefly
7.3/10
Adobe’s own video model is trained on licensed and public-domain content, its Content Credentials label AI output, and partner models from Google, Kling, Runway and Luma sit in the same app.
Firefly is the pick when legal risk matters more than chasing the top model. Adobe says the Firefly Video Model is trained on licensed content such as Adobe Stock and on public-domain material, not on Adobe users’ content, and that it doesn’t mine the web. Adobe backs Content Credentials, a provenance label that shows how a file was made and also flags when a partner model was used. Enterprise customers get IP indemnification for Firefly-generated content.
Inside the same app you also get partner models: Adobe lists Google Veo 3.1, Luma Ray3, Runway Gen-4.5 and Kling 3.0. Adobe says most models make clips of up to 8 seconds and some up to 15, several generate native dialogue and sound effects, and downloads go up to 4K. Free users get a daily allotment of generations that includes the Firefly Video Model and select partner models; the Firefly editor can add voiceovers, music and sound effects to any clip.
Flaws but not dealbreakers
Adobe’s commercial-safety promise applies to its own Firefly models. For partner models, Adobe says it’s your job to decide whether the output fits your project. Firefly’s own video model doesn’t appear on Artificial Analysis’s leaderboards, so we can’t compare its quality with the models above. Adobe’s plan prices showed in euros from our location, so we’ve left the dollar amounts out.
Who it’s for
Businesses, agencies and Creative Cloud users who need the lowest legal risk.
Who should skip it
You want the highest-ranked model for the money; Adobe's own video model isn't on the big leaderboards.
Pros
Adobe says Firefly isn't trained on user content
Content Credentials show how a file was made
Downloads up to 4K; partner models include Veo 3.1, Kling 3.0, Runway Gen-4.5 and Luma Ray3
IP indemnification for eligible enterprise customers

Other good options
For top-ranked quality: Hailuo (MiniMax H3). MiniMax H3 ranked third for text-to-video and first for image-to-video (both with audio) on Artificial Analysis when we checked. Hailuo’s site, where it runs, also offers Alibaba’s Wan 3.0, includes a 2K option and lists plans from $9.99 a month. We didn’t make it a main pick because Hailuo’s terms of service describe the service as for “personal, non-commercial use” and say commercial use of generated content is at your own risk, which is less clear than Kling’s or Runway’s terms.
For presenter videos and YouTube: HeyGen. HeyGen’s own model, HeyGen Video 1, ranked fourth with audio for text-to-video and topped the silent text-to-video board. We cover HeyGen in our YouTube video guide, because its main strength is avatar and presenter videos.
The competition
Alibaba Wan 3.0: First for text-to-video with audio on Artificial Analysis when we checked. We found it inside Hailuo and Pika rather than as a consumer app of Alibaba’s own, so we point you to those.
Dreamina (ByteDance Seedance 2.5): Ranked fifth for text-to-video and third for image-to-video with audio. You can use Seedance 2.5 through Pika or Runway Pro, which we cover above.
Luma: Luma’s own Ray models weren’t on Artificial Analysis’s text-to-video leaderboard, so we had no independent quality comparison; Runway and Pika cover the same multi-model job.
Utopai X and FLUX 3: Ranked second and sixth respectively for text-to-video. We didn’t review consumer plans for them for this guide.
Grok Imagine Video 1.5: Ranked 12th for text-to-video, behind our top pick.
Google Veo 3.1: Ranked 21st, well behind Google’s newer Gemini Omni Flash; it’s still offered in Firefly and with Google AI Ultra.
OpenAI Sora: Discontinued. OpenAI’s help center says the Sora web and app experiences ended on April 26, 2026, and the Sora API on September 24, 2026.
Watermarks, labels and commercial rights
Most generators mark their output in some way. Google embeds an imperceptible SynthID watermark in every Gemini Omni video, and Adobe uses Content Credentials, a provenance record that also notes when a partner model was used. Kling removes its brand watermark on paid plans; Pika’s pricing page lists no watermark on any plan, and Runway’s paid plans list none. Hailuo’s terms forbid removing its watermarks or labels and ask you to disclose AI content where the law requires it.
Commercial rights follow the plan, not the model. Kling’s and Pika’s free tiers don’t allow commercial use, while Runway’s help center names no plan restriction. Whether AI output can be copyrighted at all is a separate, unsettled question. If you publish realistic AI video on YouTube, check its disclosure rules, which we explain in our YouTube guide. Laws on AI content and copyright vary by country, and this guide is not legal advice.
What to look forward to
Google says image and audio output are planned for the Gemini Omni family, and that developers and enterprise customers will get API access. Kling 4.0 launched in mid-October 2026 and wasn’t on Artificial Analysis’s leaderboard yet when we checked; the leaderboard says nine models were added in the previous 30 days, so expect the rankings to keep moving. We’ll update this guide as they do.
FAQ
What is the best free AI video generator?
Google Flow gives everyone 50 credits a day, enough for a few 10-second Gemini Omni clips at 720p, and the same model is free inside YouTube Shorts and YouTube Create. Adobe Firefly also has free daily generations. Free tiers from Kling and Pika don’t include commercial rights.
Which AI video generator makes the longest clips?
Kuaishou says Kling 4.0 generates up to 30 seconds in a single pass. Most other generators top out at 10 to 15 seconds per clip, so longer videos are built by extending or stitching clips.
Can I use AI-generated videos commercially?
On most paid plans, yes. Runway’s help center names no plan restriction on commercial use, while Kling’s free plan and Pika’s free plan don’t include commercial rights. Adobe Firefly is the most cautious option because its own model is trained on licensed content. Rules vary, and this isn’t legal advice.
What happened to OpenAI's Sora?
OpenAI discontinued the Sora web and app experiences on April 26, 2026, and the Sora API on September 24, 2026, according to its help center. Users could export their content from sora.chatgpt.com/sunset.
How can people tell a video was made with AI?
Google embeds an invisible SynthID watermark in every Gemini Omni video, which you can check in the Gemini app, Chrome and Google Search. Adobe uses Content Credentials. Kling removes its brand watermark only on paid plans, and Hailuo’s terms forbid removing its watermarks.
