Sora exit (past tense): OpenAI discontinued the Sora web & app experience on April 26, 2026, and the Sora API ended on September 24, 2026, with no official OpenAI video replacement listed on the deprecations page. If you still have library assets, use the export path at sora.chatgpt.com/sunset. Sources: OpenAI Help — Sora discontinuation, OpenAI API Deprecations.
Sora is not a current pick on this page. Migrate to Kling, Runway, or Google Veo depending on workflow (below).
Quick verdict (September 2026): After Sora’s exit, the “best” AI video generator is a workflow question. Kling (VIDEO 3.0) is our top pick for most creators who need strong short-form clip quality and credit-efficient paid plans. Runway (Gen-4.x / Gen-4.5) wins when you need an editor suite (motion brush, inpaint, post tools). Google Veo 3.1 wins when you want a clear Google Cloud / Vertex $/sec API card. Sticker minutes ≠ usable minutes — budget retries.
OpenToolHQ ranking: 1) Kling · 2) Runway · 3) Google Veo 3.1 · Honorable: Luma Dream Machine / Pika / Hailuo (verify live pricing)
Quick picks: Best AI video generators at a glance
| Need | Pick | Entry paid (as of Sep 2026) | Why (short) |
|---|---|---|---|
| Best raw clip quality / social B-roll on a budget | Kling | Standard ~$6.99 first → ~$8.80 renew | Native audio + multi-shot; commercial + watermark removal on paid |
| Best editor / post / motion-control workflow | Runway | Standard $15/mo ($12 annual) | Gen-4.5 + suite tools; credits ~12/sec on Gen-4.5 |
| Best Google Cloud / Vertex $/sec clarity | Google Veo 3.1 | Pay-per-second (~$0.03–$0.60/sec by tier) | Clear API price card; enterprise billing path |
| Former OpenAI Sora user | Not Sora | API ended Sep 24, 2026 | Export library → pick Kling / Runway / Veo by job |
| Lightweight alt playgrounds | Luma / Pika / Hailuo (honorable) | Varies — verify | Only if SERP / niche fit demands a fourth seat |
As of the week of Sep 28–Oct 4, 2026, Sora is a migration story, not a live competitor. The commercial question is which post-Sora stack fits your job: credit-efficient creator clips (Kling), editor-first post production (Runway), or Google Cloud $/sec pipelines (Veo 3.1). Plan names, credit burn rates, and watermark rules move fast — treat every price below as a signal and verify at checkout on the linked vendor pages.
This page is a research-based editorial roundup. We compare official product positioning, pricing pages, workflow fit, commercial-rights language, and who should use each tool. We do not invent benchmark scores, fake usable-minute prices, or anonymous quotes.

How we evaluate AI video generators
We score tools the way creators and small marketing teams actually buy them:
- Usable clip quality — First-pass keep rate for short-form / B-roll, not arena screenshots.
- Workflow fit — Pure generate vs editor suite vs Cloud/API pipeline.
- Price honesty — Sticker plan + credit/sec tables + retry factor as a method (not a fake exact $/usable minute).
- Watermark & commercial language — Quote vendor plan tables / terms; re-read ToS before client delivery.
- Consistency & controls — Image-to-video, references, multi-shot, audio, motion tools — and known drift limits.
We prefer “best for X” over a fake single trophy. Winner bias here means: for most OpenToolHQ readers leaving Sora for short-form creator work, Kling is the default start.
Comparison table (as of September 2026)
| Factor | Kling (VIDEO 3.0) | Runway Gen-4.x / 4.5 | Google Veo 3.1 |
|---|---|---|---|
| Best for | Creator clips / social B-roll value | Editor + motion / inpaint workflow | Vertex / Google Cloud pipelines |
| Entry paid signal | Standard ~$6.99 intro / ~$8.80 renew (660 credits) | Standard $15/mo or $12 annual (625 credits) | Pay-per-second Cloud SKUs |
| Meter shape | Credits; purchased ~$1 = 66 credits; 4K ref ~30 cr/sec | Credits; Gen-4.5 ~12 cr/sec; API credit ~$0.01 | $/count on Cloud pricing table (treat as $/sec pending unit confirm) |
| Audio | Native audio + multi-shot (vendor) | Suite + multi-model access (incl. hosted third-party models) | Video+Audio SKUs priced separately from video-only |
| Watermark / commercial | Basic non-commercial; Standard+ commercial + watermark removal (vendor table) | GAP — verify Free vs paid Help/Terms before absolute claims | Gemini app vs Vertex terms differ — don’t conflate |
| Main tradeoff | Lip sync + multi-clip character drift; queue / credit burn on 4K | Gen-4.5 burns fast; credits don’t roll on Standard/Pro | Cloud account friction for solo creators |
$/usable minute — method, not a fake number
Vendors sell credits or seconds of generation, not “approved Instagram cuts.” A usable minute is roughly:
(vendor $ per generated second) × 60 × (retry factor)
Where retry factor is how many generated seconds you burn per second you keep (often 2–5× depending on prompt discipline — your number, not ours). Examples from public rate cards (research Sep 23, 2026):
- Kling 4K planning ref: ~30 credits/sec × ~$0.0152/credit (~$1/66) ≈ ~$0.46/sec ≈ ~$27/min of successful 4K before retries. Standard’s 660 credits ≈ ~22 sec of that 4K rate — or more at lower res. Exact 720p/1080p credit/sec tables vary by mode — confirm in-app.
- Runway Gen-4.5 API math: 12 credits/sec × $0.01 ≈ ~$0.12/sec ≈ ~$7.20/min if every second is kept. Standard 625 credits ≈ ~52s Gen-4.5 raw.
- Veo 3.1 (assuming Cloud “/1 count” = per second — verify tooltip): Video+Audio 1080p ~$0.40/sec → ~$24/min; Fast video+audio 720p ~$0.10/sec → ~$6/min; Lite video-only 720p ~$0.03/sec → ~$1.80/min — all before failed gens.
Always separate sticker minutes from usable minutes.
1. Kling (Kuaishou) — Best overall post-Sora creator pick
Official: kling.ai · VIDEO 3.0 credit guide · Point / credit policy
Kling is our default recommendation for creators and marketers leaving Sora who need strong short-form motion, native audio, and a credit plan that doesn’t require a Cloud account. Deep dive: our live Kling 3.0 review.
Pricing (as of Sep 23, 2026 — vendor blog; verify at checkout)
| Plan | Visible offer | Renewal signal | Credits | Notes |
|---|---|---|---|---|
| Basic | $0 | — | Login / daily style | Not for commercial use; watermarked |
| Standard | $6.99/mo first | $8.80/mo | 660/mo | Commercial use; watermark removal; 1080p |
| Pro | $25.99/mo first | $32.56/mo | 3000/mo | Same commercial + de-watermark + priority features |
| Premier / Ultra | Higher first-month offers | Higher renew | 8000 / 26000 class | Heavy volume pools |
Purchased credits: $1 = 66 credits (membership credits ~1 month validity; purchased longer — see point policy). 4K ref: ~30 credits/sec for Kling VIDEO 3.0 series 4K on the vendor credit guide — re-check the generation panel day-of.
- Strengths: Quality/price for short-form; native audio + multi-shot; paid commercial + watermark removal language on Standard+.
- Gaps: Lip sync imperfect; character drift across multi-clip projects; queues; 4K/multi-shot credit burn; some enterprises flag China-vendor compliance (flag only — not legal advice).
Best for: Social creators, marketers needing B-roll, and Sora refugees who want the simplest paid upgrade path.
Skip if: You need heavy masking/motion-brush post tools (Runway) or a Google Cloud compliance path (Veo).
2. Runway — Best editor / post workflow
Official: runway.com · Pricing · API / developer pricing
Runway wins when generation is only half the job — you also need motion brush, inpainting, Aleph-style edits, and a creator suite. Treat “Runway hosts Kling / other models” as an access path, not a separate ranked winner: native Gen-4.x / Gen-4.5 plus editing tools are the differentiator.
Pricing (as of Sep 23, 2026 — verify at checkout)
| Plan | Public sticker | Credits | Notes |
|---|---|---|---|
| Free | $0 | 125 one-time | Trial pool |
| Standard | $15/mo or $12/mo annual | 625/mo | ≈52s Gen-4.5 or ≈104s Gen-4 Turbo at published burn rates |
| Pro | $35/mo / $28 annual | 2250/mo | Heavier creators |
| Max | $95/mo / $76 annual | 9500/mo | Limited rollover on Max (vendor) |
Page states Gen-4.5 uses 12 credits per second. API docs: credits $0.01 each; gen4.5 = 12 cr/s; gen4_turbo = 5 cr/s. Credits generally do not roll on Standard/Pro — plan around monthly burn.
Watermark / commercial GAP: Secondary sources often say Free is watermarked and paid is commercial; verify Runway Help (“Which plan is right for me?”) and current Terms before stating absolutes. Do not invent.
- Strengths: Best-in-class editing / control suite; clear credit examples; multi-model router for experimentation.
- Gaps: Gen-4.5 burns fast; Standard’s ~52s/mo of Gen-4.5 is easy to exhaust; SERP confusion from legacy “Unlimited” plan language.
Best for: Editors, agencies, and anyone who iterates with masks, motion, and inpaint — not just text-to-video one-shots.
3. Google Veo 3.1 — Best Google Cloud / Vertex pipeline
Official pricing: Google Cloud generative AI pricing · Product docs: Veo / video on Vertex
Veo 3.1 is the pick when your org already bills Google Cloud, needs a published $/sec-style card, or wants Vertex compliance paths. Solo creators should weigh Cloud account friction against consumer Gemini packaging (GAP: confirm whether Gemini paid plans include Veo minutes and at what caps).
Pricing signals (as of Sep 23, 2026 — verify units on page)
| SKU (examples) | Published Price (USD) / 1 count | Derived $/min if count = 1 sec |
|---|---|---|
| Veo 3.1 Video+Audio 720p/1080p | $0.40 | ~$24/min |
| Veo 3.1 Video+Audio 4K | $0.60 | ~$36/min |
| Veo 3.1 Video only 720p/1080p | $0.20 | ~$12/min |
| Veo 3.1 Fast Video+Audio 720p | $0.10 | ~$6/min |
| Veo 3.1 Fast Video+Audio 1080p | $0.12 | ~$7.20/min |
| Veo 3.1 Lite video-only 720p | $0.03 | ~$1.80/min |
Unit caution: Google’s table labels “Price (USD)” as “/ 1 count” for video rows. Industry practice and many Google video SKUs treat this as per second of generated video. If the tooltip is ambiguous at publish, quote the table literally and link — do not invent a different unit.
- Strengths: Clearest enterprise API price card; Google Cloud billing / IAM path; Fast/Lite tiers for cost control.
- Gaps: Creator UX friction vs Kling/Runway web apps; consumer Gemini vs Vertex rights/watermarks differ; character consistency still project-dependent.
Best for: Google-first teams, product features that need Vertex, and buyers who must show finance a $/sec spreadsheet.
Sora exit checklist (not a pick)
- Web/app discontinued Apr 26, 2026; API discontinued Sep 24, 2026 — sources linked in the red callout above.
- Deprecations list Videos API +
sora-2/sora-2-pro(+ snapshots) with recommended replacement = none. - Export remaining library via sora.chatgpt.com/sunset → Export.
- Purchased ChatGPT/Sora credits may still apply to other OpenAI products (per Help) — that is not a video migration path.

Honorable mentions
Luma Dream Machine, Pika, Hailuo — keep on a longer shortlist if a niche (specific motion style, community workflow, or regional availability) fits. We do not invent ranking scores or stale third-party prices here; verify official pricing pages before budgeting a fourth seat. Runway-hosted third-party models are an access path inside Runway, not separate “best of” winners.
Who should pick what
- Sora refugee, short-form / social B-roll: Start Kling Standard; read our Kling review for limits.
- Editor who lives in masks, motion brush, inpaint: Runway Standard/Pro.
- Google Cloud / Vertex shop: Veo 3.1 (Fast/Lite for drafts; full 3.1 for finals).
- Still → motion pipeline: Generate hero frames with tools in our Best AI Image Generators 2026 roundup, then animate in Kling or Runway.
- Enterprise compliance first: Prefer Veo on Vertex or Runway with counsel-reviewed terms; flag Kling vendor geography for security review — not legal advice.
- Budget-constrained: Kling Standard’s intro/renew ladder is usually cheaper to test than Runway’s Gen-4.5 burn or Veo full-quality audio SKUs — still measure keep rate.
FAQ
What is the best AI video generator in 2026 after Sora?
For most OpenToolHQ creator readers, Kling. If you need a full editor suite, Runway. If you need Google Cloud $/sec billing, Veo 3.1. There is no universal trophy.
Is Sora still available?
No as a current product path. Web/app ended Apr 26, 2026; API ended Sep 24, 2026. There is no official OpenAI video replacement on the deprecations list. Export any remaining assets and migrate.
Kling vs Runway vs Veo — which is cheapest?
Depends on retries and resolution. Kling Standard is often the cheapest seat to start. Runway Gen-4.5 can get expensive per kept second. Veo Lite/Fast can win on Cloud if approval rates are high. Always compute usable minutes, not sticker minutes.
Can I use AI video commercially?
Often yes on paid tiers, with vendor-specific catches (Kling Basic is non-commercial; Runway Free vs paid needs verification; Gemini app vs Vertex differ). This is not legal advice — read current Terms for your entity.
Do AI video tools keep characters consistent?
Improved with image references / element workflows, but multi-clip drift is still common. Do not treat consistency as “solved.”
Where should I start if I already make stills?
Use our image generators roundup for hero frames, then Kling or Runway for motion. Browse more in Creative AI.

The bottom line
Sora’s consumer surface and API are gone. The best AI video generator in late September 2026 is the post-Sora stack you will actually ship with:
- Kling — best overall creator / social B-roll pick (Standard ~$6.99→$8.80).
- Runway — best editor / post workflow (Standard $12–15/mo).
- Google Veo 3.1 — best Vertex / Cloud $/sec clarity ($0.03–$0.60/sec class by tier).
Export any remaining Sora library. Pick one paid path. Measure keep rate for two weeks before stacking a second seat.
Product details and pricing signals were checked against official OpenAI Help/Deprecations, Kling, Runway, and Google Cloud pages on Sep 23, 2026 for a planned stamp around Sep 28–Oct 4, 2026 and may change — verify at checkout.
