Best AI Video Generators Compared: Models, Platforms and Real Per-Second Prices

There is no single best AI video tool, and the honest answer depends on your shot type and your budget. Higgsfield is the tool most ReelStack creators list (211 of 589), but it is a wrapper: it runs Kling 3.0, Seedance 2.5, Veo 3.1, Wan 3.0 and MiniMax H3 under its own credits and presets. For some models the maker's own route costs less, and for others the wrapper does. Pick the model for the shot first, then compare per-second prices.

Key Takeaways

• 211 of 589 ReelStack creators list Higgsfield, a wrapper. Kling AI (71) and Google Veo (45) are the model-maker routes our creators list most.
• The newest models are Wan 3.0 (generally available on Alibaba Cloud on Aug 24, 2026), Seedance 2.5 and MiniMax H3 (both July 2026). Both Wan 3.0 and Seedance 2.5 offer up to 30-second clips.
• Seedance 2.5 at 720p costs $0.035/s on a Dreamina promo that ends today (Oct 9, 2026), $0.231/s on BytePlus, $0.32/s on Higgsfield and $0.72/s on Runway.
• Leaderboards disagree. Arena's September 2026 board has Gemini Omni 1.1 Flash #1 for text-to-video and MiniMax H3 #1 for image-to-video, while llm-stats has Kling v3 #1.

Models vs platforms: what a wrapper is

A model is the AI system that generates the video: Veo, Kling, Seedance, Wan, MiniMax H3. A model maker (Google, Kuaishou, ByteDance, Alibaba, MiniMax) sells access to its own model. A platform or wrapper resells several makers' models behind one login, one credit balance and its own presets.

Higgsfield is our example. It lists Kling 3.0, Seedance 2.5, Seedance 2.0, Veo 3.1, Sora 2, Wan 3.0 and MiniMax H3 (Higgsfield credits vs unlimited). Runway is a hybrid: it makes Gen-4.5 and also resells Seedance 2.5, Kling 3.0 and Veo 3.1 on paid plans (Runway pricing). fal.ai and Hedra are developer-facing wrappers. A wrapper's price is the maker's price plus its own credit system, so the same clip can cost very different amounts.

The newest models right now

Clip length is the clearest change this year. Wan 3.0 and Seedance 2.5 both reach 30 seconds in one pass, where Kling 3.0 stops at 15. A Kling 4.0 launch was reported as due in October 2026, but no primary source confirms it, so treat it as unannounced. Gemini Omni Flash has preview and stable model IDs, so check which one a platform actually calls.

How the models compare on quality

These are dated snapshots, and they change with every new model. The llm-stats ordering conflicts with Arena's September ordering and the two haven't been reconciled. Arena also lists Seedance 2.0, not 2.5. Wan 3.0 is described as #1 on the Artificial Analysis text-to-video board with audio (Pinggy). Check the live boards before you pay.

Three observations matter more to filmmakers than rank:

• Kling 3.0: DejaOffice's July 2026 test found human movement looks more natural than most rivals, with multilingual lip-sync for dialogue (DejaOffice).
• Veo 3.1: the same test found its native 48 kHz audio usually needs little cleanup for dialogue and ambience, and camera movement is handled well.
• Runway Gen-4.5: Fliki says it improved full-body tracking and hand movement, but has a 720p base resolution that needs upscaling for 4K (Fliki).

What each model costs, platform by platform

Prices are as of October 2026. Per-second rates are at the resolution shown. Derived values are marked with ~.

Why these prices don't compare cleanly

• Credits are not dollars. Higgsfield and Runway bill in credits that expire. Higgsfield plan credits expire at each renewal, and Runway credits don't roll over except on Max. Runway's API is billed separately at $0.01 per credit, so API rates and subscription math won't match.
• Resolution and duration differ. The Higgsfield and Runway Seedance clip costs use 8 s clips, MiniMax is 2K, Gemini's 1080p and 4K are upscaled outputs, and Venice only publishes a starting price per clip.
• Promos distort the picture. Dreamina's rate ends today, Wan 3.0's 30% launch discount ran Aug 24 to Sept 23, and Higgsfield's MiniMax H3 promo has no published end date.
• "Unlimited" has fine print. Higgsfield's 7-day and 365-day windows cover selected models only, run on higgsfield.ai only, and may slow at peak times (Higgsfield). Sources also disagree on whether Runway still offers an unlimited plan.
• Failed generations still cost. On credit platforms, rerolls burn credits, so the cost of a usable clip is higher than the cost of one attempt. Sources also conflict on Flow credit costs and Runway's per-second credit rates.

Our conclusions from a quick round of research, as of October 2026:

• Gemini Omni Flash: EvoLink looked cheapest among APIs at about $0.087/s versus Google's $0.10/s, because it prices 15% under Google's list. That is a token-based estimate that excludes input and thinking tokens. Google AI Plus is cheaper per second but is a consumer credit system, not API access.
• Wan 3.0: Ofox's flat $0.05/s looked like the lowest published single rate, but it comes from one third-party snapshot. Higgsfield's API range starts at $0.025/s without mapping prices to resolutions, so the two can't be ranked.
• Seedance 2.5: Dreamina's $0.035/s is the lowest consumer price, but only for a first month that ends today. For sustained API use, BytePlus looked like the lowest official rate, and Cellcog's comparison lists that route as not sold in the US, Canada, UK, Australia or New Zealand (Cellcog).
• MiniMax H3: Higgsfield's $0.065/s promo halves the $0.13/s on MiniMax and fal, but the promo end date isn't published.

What ReelStack creators actually use

Higgsfield sits at the top of our whole directory, not just video. Our creators often list several models side by side. Rezowan Karim lists Google Flow, Seedance, Kling, Sora, Runway and Hailuo in one headline, and Simone Dior lists both Kling and Veo 3. Arik Renee Avila lists both Kling and MiniMax. The directory shows what creators list, not why, so read this as a signal that people mix models rather than commit to one.

Published work shows the mix. NORMAN TRANQUILITY - AI Short film by Julien Guiol used MiniMax. THE POLITICAL by Simone Dior used Veo 3. Ikan Tak Dapat, Cerita Tetap Hebat by Bang ucil lists both Kling and Veo 3. Spectacles ad final by Anton Kuzmenko used Kling.

Our daily briefs keep returning to cost control:

• The Sep 21 brief covers targeted resolution tiering to control render costs.
• The Sep 29 brief says specialized model routing and framing-aware keyframing eliminate credit waste across multi-shot sequences.
• The Sep 14 brief covers pairing 3x3 grid prompting with last-frame video extensions in Seedance 2.5 to keep continuity across long sequences.

Higgsfield

Higgsfield is a credit-based aggregator with presets, cinema tools, a Marketplace pass model and a public pay-per-generation API that launched Sept 17, 2026 (Higgsfield). Credit cost depends heavily on the model: Kling 3.0 is listed at about 6-7 credits per 5 s clip, while Sora 2 and Veo 3.1 run 40-70 credits per generation. A plan's clip count therefore swings with the model you choose.

Pricing can also vary by region. Sora's status is unclear: sources conflict on whether OpenAI's Sora API and app are still running, yet Higgsfield still lists Sora 2, so confirm it works before building a plan around it. The Wan 3.0 credit rate isn't published.

Google Veo / Gemini Omni Flash

Google is a model maker, and its Gemini API docs now recommend Gemini Omni Flash as the default video model (Google). Veo 3.1 comes in three tiers, all with audio, and Lite is the cheapest Google-hosted option (Google pricing). Veo 3 at $0.75/s is a superseded listing from 2025.

It suits developers who want per-second billing and creators who want Google-hosted models inside Flow. Flow's free tier gives 50 credits a day with no rollover, and Veo 3.1 Quality (100 credits) can't be reached on that allowance. There is no free Gemini API tier for Veo 3.1 or Omni Flash. Flow credit costs and the Google AI Plus price ($4.99 or $7.99 a month) conflict across sources, so check Flow before budgeting.

Kling AI

Kling 3.0 is a strong starting point when a shot is about people: native audio, lip-sync, 15-second generations and native 4K. Paid plans include 1080p/4K output, watermark removal and commercial use. Standard is $6.99 for the first month, then $8.80 a month (660 credits). Pro is $25.99 first month, then $32.56 a month (3,000 credits) (Kling pricing). The free plan is watermarked and not for commercial use, and its daily allowance is stated differently across sources.

Per-clip cost comes from third-party credit counts, not a Kling price list, and those figures use first-month prices, so steady cost is higher. Retries are common, so a publishable scene can take several attempts. Premier, Ultra and API pricing aren't covered here.

MiniMax H3

MiniMax H3 (marketed as Hailuo 3.0) is the one model in this guide with downloadable weights. It gives 2K output via API with native stereo audio and up to 9 image references, the first 5 free (Leadde). MiniMax and fal charge the same 2K rate, so choose between them on tooling, not price. H3 Max is a separate fal variant with its own pricing.

The open weights stop at 768p, and the 2K regeneration module is hosted only. The community license has restrictions, so read it before self-hosting. Video subscription packages don't support H3 yet, so it is pay-as-you-go.

Seedance 2.5

Seedance 2.5 is ByteDance's July 2026 model: up to 30 seconds of audio-video in one pass, multi-round extension and stronger reference-based editing over Seedance 2.0. It accepts up to 50 references (30 images, 10 videos, 10 audio clips), per Dreamina's launch page. Dreamina has a free sign-up with no card, though the daily credit amount isn't published.

This is where wrappers cost the most: the same 720p model is more than three times as expensive on Runway as on BytePlus. Dreamina's promo is a one-month offer (Dreamina). Its annual Super first-year offer is $0.047/s, and the two offers are separate commitments, not stackable. The BytePlus API outputs 480p or 720p, and sources conflict on whether 1080p exists. Dreamina has no public API.

How to choose

• Dialogue and human performance: start with Kling 3.0 for movement and lip-sync, or Veo 3.1 for audio that needs little cleanup. Buy Kling direct if you only need Kling.
• Tightest API budget: Veo 3.1 Lite is the lowest Google rate. Wan 3.0 on Alibaba Cloud is the next step up at 720p.
• Long single shots: Seedance 2.5 or Wan 3.0 for 30-second clips. Use Dreamina or BytePlus for Seedance rather than a wrapper, if your region allows it.
• Image-to-video at 2K: MiniMax H3 on MiniMax or fal, or the Higgsfield promo while it lasts.
• One login for many models: Higgsfield or Runway. Expect credit-based pricing and plan for rerolls.
• Local or self-hosted: MiniMax H3 open weights, with a 768p cap and a license to read first.

Before you pay, re-check promo end dates and the live leaderboards.

FAQ

What is the best AI video generator right now?

There isn't one; the leaderboards above disagree. Choose by shot type first, then compare per-second prices across makers and wrappers.

Is Higgsfield cheaper than buying direct?

It depends on the model. It was more expensive than the maker route for Seedance 2.5 and cheaper for MiniMax H3 while its promo lasts. Kling and Veo credit rates differ by model and can't be compared cleanly with the makers' own plans.

Which AI video model is cheapest per second?

In our quick research, Veo 3.1 Lite looked cheapest among official 720p rates. Cheaper figures exist, such as Dreamina's promo and Ofox's flat Wan 3.0 rate, but the first is time-limited and the second comes from a single source.
