Sora 2 vs Veo 3 vs Runway vs Kling: What Replaces Sora
Sora 2 vs Veo 3 vs Runway Gen-4.5 vs Kling 3. Sora was shut down on Sept 24, 2026: what to use instead, USD pricing, and a same-prompt test of all four.
Table of contents
Updated September 24, 2026. For most of 2026 the four dominant AI video generators were Sora 2, Veo 3, Runway Gen-4, and Kling 3. Today three are left: Sora 2 has been shut down. In short: Veo 3 / 3.1 is now the go-to tool for dialogue with native audio, Runway Gen-4.5 gives precise camera control, cross-clip character consistency and, since December 2025, native audio, and Kling 3 is the cheapest option with the best dynamic motion. This comparison covers price, clip length, audio, image-to-video, and availability, with a verdict for every major use case and the results of a same-prompt test we ran while Sora was still live.
Sora 2 no longer works. OpenAI closed sora.com and the iOS/Android apps on April 26, 2026, and shut down the Sora 2 and Sora 2 Pro API on September 24, 2026, with no successor. Services that resold Sora through the API, such as fal.ai, stopped working as well. The practical choice is Veo 3, Kling 3, Runway Gen-4.5, and LTX for cheap local iteration. We keep Sora 2 in this comparison as a benchmark (data marked "as of 09.2026"), because its prompts transfer well to the other tools. See Sora 2 vs Veo 3 for the migration angle.
TL;DR: what to use after Sora (September 2026):
- Veo 3 / 3.1: social ads with dialogue and native audio, rich texture detail. 4, 6 or 8 s per generation, longer via extend. Google AI Pro ($19.99/month) or pay-per-clip via Kie.ai. Full course page.
- Runway Gen-4.5: product ads with precise prompt-driven camera moves, References, and native audio. Pro $28/month billed annually ($35 month-to-month). Full course page.
- Kling 3: cheapest subscription, best dynamic motion (dance, sports, fitness). From $10/month. Full course page.
- LTX 2.3: open source, free locally on an NVIDIA GPU (8 GB VRAM minimum), good for fast iteration and B-roll.
- Sora 2: shut down on September 24, 2026. What to do with your Sora prompts.
Quick Pick by Use Case
The fastest path to the right tool is matching it to your goal, not comparing spec sheets. The table below maps common creator and business scenarios to the best working choice in September 2026.
| Your Goal | Best Pick | Starting Price (USD) |
|---|---|---|
| Social ads with audio and dialogue | Veo 3.1 | $19.99/mo (Google AI Pro) or ~$0.30 per 8 s clip (Kie.ai, Fast) |
| Longer product walk-throughs (30+ s) | Veo 3.1 with extend, or several shots edited together | $19.99/mo or pay-per-clip |
| Precise camera control (dolly, orbit) | Runway Gen-4.5 Pro | $28/mo annually, $35 monthly |
| Cheapest clips with dynamic motion | Kling 3 Standard | ~$10/mo |
| Cross-clip character consistency | Runway Gen-4.5 Pro | $28/mo annually, $35 monthly |
| Image-to-video (product photo animation) | Runway Gen-4.5 | $12/mo annually, $15 monthly |
| Budget under $15/month | Kling 3 Standard | ~$10/mo |
| Zero budget, NVIDIA GPU at home | LTX 2.3 locally | $0 (electricity) |
What Are These Tools and How Do They Work?
An AI video generator is a machine-learning model that converts a text prompt, or a reference image, into a moving video clip. Under the hood, diffusion neural networks (similar to those powering image generators like Midjourney) are extended with a third dimension: time. The model learns motion physics, cross-frame object continuity, and lighting consistency from huge amounts of training footage.
The four players that dominated the market in 2026:
- Sora 2 by OpenAI: second-generation model, known for native audio with lip-sync and a cinematic look out of the box. Shut down: app closed April 26, 2026, API off since September 24, 2026. Details at our Sora 2 page.
- Veo 3 by Google DeepMind: Google's flagship video model with native audio and dialogue, available via Google AI Pro, the Gemini API, and resellers such as Kie.ai. Full guide at our Veo 3 course page.
- Runway Gen-4.5 by Runway ML: the most professional tool in the group, built for agencies, with camera moves described in the prompt, References for character consistency, and native audio since December 2025. Motion Brush and Director Mode belonged to the retired Gen-2 and are not part of Gen-4 or Gen-4.5. Step-by-step at our Runway course page.
- Kling 3 by Kuaishou: Chinese entry that undercuts competitors on price and wins on dynamic human motion. Full workflow at our Kling 3 course page.
Worth adding to the list: LTX 2.3, an open-source model (Apache 2.0) you run for free locally in ComfyUI on an NVIDIA card with at least 8 GB of VRAM. It does not match Veo on quality, but it is enough for B-roll and fast iteration.
Each model has different training data, a different architecture, and a different commercial focus. There is no single "best", only concrete tasks where one beats the others. The rest of this comparison shows when and why.
Sora 2: What Happened and What It Means for You
Sora 2 was OpenAI's flagship video model. The second generation (October 2025, in ChatGPT Plus and Pro) added native audio with lip-sync, improved liquid and fabric physics, and clips up to 20 s in Pro. It was the tool most likely to give you a "wow" result on the first render.
OpenAI then wound it down in two steps: on April 26, 2026 it closed the consumer app (sora.com, iOS, Android), and on September 24, 2026 it shut down the Sora 2 and Sora 2 Pro API. There is no successor. You can no longer use Sora directly or through third-party wrappers such as fal.ai, because they relied on the same API.
What to do with your Sora prompts
Prompts written for Sora (scene description, camera move, lighting, dialogue in quotes) port well to Veo 3.1. Two things change: length (Veo gives 4, 6 or 8 s per generation, Sora went up to 20 s) and how you describe dialogue. The course PDF includes a ready "Sora 2 to Veo 3" migration section in chapter 6.
Veo 3 / 3.1: Who It Is For and What It Costs
Veo 3 is Google DeepMind's flagship generator. Version 3.1 generates native audio with dialogue, 1080p output (4K via the API), and rich texture detail, especially fabric, hair, and water. A single generation is 4, 6 or 8 seconds. For longer scenes there is extend: each extension adds 7 s, up to 20 times, for a total of up to 148 s, but extension works at 720p only. With Sora gone, Veo is the natural choice for dialogue-driven clips.
Who should use Veo 3?
Veo is ideal for social creators and local businesses that want ads with a voiceover or a talking character, and for real estate, B2B startups, and educators who assemble longer narratives from several 8 s shots. Teams already paying for Google Workspace or Google One get it at little or no extra cost. Explore full prompt parameters and workflow at our Veo 3 course page.
Veo 3 pricing in USD
Veo 3 has no standalone subscription: it is bundled with Google AI Pro at $19.99/month, with monthly generation limits. The alternative is pay-per-clip through an API reseller such as Kie.ai, roughly $0.30 per 8 s clip on the Fast tier and around $1.30 on the Quality tier (as of May 2026). Google also offers pay-as-you-go access through the Gemini API. See our Sora 2 vs Veo 3 comparison for a side-by-side breakdown.
Runway Gen-4.5: Who It Is For and What It Costs
Runway is the most professional tool in the group. The New York studio was among the first to build AI video workflows for ad agencies. Gen-4 (2025) and Gen-4.5 (released December 1, 2025) focus on very accurate execution of camera and motion described in the prompt, References (cross-clip character consistency from 1-3 photos), and editing finished clips in Aleph. A single Gen-4.5 generation is 5 or 10 s. The December 2025 update (TechCrunch, Dec 11, 2025) added native audio, dialogue, and multi-shot generation. If you are looking for Motion Brush or Director Mode sliders, those were Gen-2 features and are not in Gen-4 or Gen-4.5; today Kling is the tool with a motion brush.
Who should use Runway Gen-4.5?
Runway is for freelance filmmakers, ad agencies, and product photographers who need more precision than "type a prompt and get a clip." It excels in fashion campaigns (fabric motion described in the prompt), beauty ads, furniture and automotive ads, and architecture. When camera movement or character consistency across multiple shots is non-negotiable, Runway is the strongest choice. Full tutorial at our Runway course page.
Runway pricing in USD
The free plan gives a starter credit pool for a few test clips. Standard is $12/month billed annually or $15 month-to-month. Pro is $28/month billed annually or $35 month-to-month, the plan you actually pick Runway for. Max is $76/month billed annually or $95 month-to-month, for daily heavy use. Enterprise pricing on request with a DPA. All details at our Runway course page.
Kling 3: Who It Is For and What It Costs
Kling 3 is Kuaishou's answer to the Western giants. The third generation (late 2025) surprised the market on two fronts: it undercuts competitors on price and dominates one category, dynamic human motion. Dance, sports, fitness, fight choreography, hip-hop: the things other models struggle with, Kling executes without effort. For social channels that live on high-energy content, it is the fastest way to scale production.
Who should use Kling 3?
Kling 3 is the first choice for TikTok and Instagram Reels content creators, fitness trainers, choreographers, and sportswear brands. English prompts are fully supported. Full guide with prompt templates at our Kling 3 course page. Also see our Kling 3 vs Runway Gen-4 comparison for a focused head-to-head.
Kling 3 pricing in USD
The free plan gives a starter credit pool with watermark (5-10 test clips). Standard is approximately $10/month: commercial license, 720p, no watermark. Premium is approximately $25/month: 1080p, clips up to 20 s, priority queue. Master is approximately $55/month: full Pro feature set. Payment by major credit cards via Stripe. For users with a subscription budget under $15/month, Kling 3 Standard is the most sensible choice in this group.
Pricing Comparison in USD (September 2026)
The most common question from new creators: how much does a full month of active use actually cost? The table below shows the pricing breakdown across plans. The Sora row stays as a record, as of 09.2026.
| Tool | Free Tier | Entry Paid Plan | Pro Plan | Top Plan | Pay-as-you-go |
|---|---|---|---|---|---|
| Veo 3 | None (starter credits at resellers) | $19.99/mo (Google AI Pro) | Workspace Business | Enterprise | Gemini API; Kie.ai ~$0.30 (Fast) / ~$1.30 (Quality) per 8 s |
| Runway Gen-4.5 | Starter credits | $12/mo annually, $15 monthly (Standard) | $28/mo annually, $35 monthly (Pro) | $76/mo annually, $95 monthly (Max) | Per-credit API |
| Kling 3 | Credits with watermark | ~$10/mo (Standard) | ~$25/mo (Premium) | ~$55/mo (Master) | Per-credit API |
| LTX 2.3 | $0 locally (NVIDIA GPU, 8 GB VRAM min.) | Open source (Apache 2.0), you only pay for electricity | |||
| Sora 2 (shut down) | As of 09.2026: ChatGPT Plus $20/mo, Pro $200/mo, API ~$0.03-0.07/s. App closed April 26, 2026, API shut down September 24, 2026. | ||||
How many clips can you generate per $50?
Each tool bills credits differently, and cost depends on clip length and resolution. Rough benchmarks:
- Veo 3 Fast via Kie.ai: around 160 clips of 8 s for $50 (at ~$0.30 per clip). On the Quality tier, around 35-40 clips.
- Veo 3 via Google One ($19.99/mo): a monthly generation allowance in the Gemini app, good value if you already pay for Google One.
- Runway Pro ($28-35/mo): 2,250 credits per month; the number of clips depends on model, length and resolution, and drops with References and higher quality settings.
- Kling Standard ($10/mo): approximately 50-60 clips at 720p. Premium ($25/mo), roughly 150 clips at 1080p.
A typical 30-second social ad (a few shots plus editing) costs roughly $2-4 in credits when amortized across a monthly plan. For reference, an external agency charges $1,200-2,000 for the same deliverable; a camera operator freelancer charges $400-600.
Feature Comparison Table
Price is only the starting point. The real differences show up in features. The Sora column stays as a benchmark (as of 09.2026); for a purchase decision, look at the other three.
| Feature | Veo 3.1 | Runway Gen-4.5 | Kling 3 | Sora 2 (shut down, as of 09.2026) |

Head-to-Head Test: Same Prompt, Four Tools (March 2026)
In March 2026, while Sora 2 was still live, I ran a direct comparison: the same English prompt submitted to each of the four generators on their base paid plan. The prompt was: "A woman in a red coat walks through a cobblestone old town square at golden hour, camera tracking alongside her in a smooth side-angle tracking shot, cinematic film look, 35mm lens, natural sunlight, 9:16, 10 seconds." No reference images, no motion brush, no special add-ons: a clean text-to-video test. The results are historical; you cannot rerun the Sora part today.
Sora 2 Plus: best cinematic look out of the box (as of 09.2026)
Sora delivered the most cinematic result on the first try. Golden-hour lighting was near-perfect: soft glow, warm colors, long shadows. The coat had realistic fabric texture and moved naturally with the character's stride. Audio included natively: footsteps on cobblestone, ambient city noise, light reverb. Weak point: the "old town" looked like a generic European city. Subjective score: 9/10. This result can no longer be reproduced, as Sora is shut down.
Veo 3: best detail, but tracking shot less dynamic
Veo won on details. The cobblestones looked textured and real; the surrounding buildings had architectural specifics (drainpipes, shutters); the character's facial expression was more naturalistic than any competitor. The tracking shot was less energetic, closer to a slow, almost static follow. Instead of 10 s I got 8 s, the maximum for a single Veo generation, clean with no glitches. Audio present, slightly weaker than Sora. Score: 8/10. With Sora gone, this is the closest replacement.
Runway Gen-4 Pro: most precise camera movement, slowest render
Runway interpreted the tracking shot most accurately: the camera moved in a perfect parallel line beside the character. Cinematic look was strong. The test clip had no audio. Render time was 4 minutes, the longest of the four. The character's face showed minor inconsistencies between frames without a Reference image. Score: 8.5/10. Note: Gen-4.5 has generated native audio since December 2025, so the missing-audio drawback no longer applies.
Kling 3 Standard: fastest and cheapest, weakest cinematic
Kling produced the clip fastest (under 90 seconds) and the result looked fine for TikTok or Reels. In a direct comparison with Sora and Runway, the cinematic look fell short: colors less saturated, depth of field flatter, character movement more "animated" than physically real. No dialogue. Score: 7/10, with a strong asterisk for price-to-quality ratio.
Conclusion for today: for the fastest good clip with sound, use Veo 3.1. For precise camera work, use Runway Gen-4.5. For the cheapest viable motion-heavy workflow, use Kling 3. The full multi-tool workflow from prompt to published social post is covered in the AI video course hub.
Verdict: Best Tool per Use Case
There is no single favorite, only a decision matrix. Below are recommendations for the most common creator and business profiles, now without Sora.
For social media content creators (TikTok, Reels)
The combination of Veo 3 ($19.99/mo or pay-per-clip) + Kling 3 Standard ($10/mo) covers most short-form content needs. Veo 3 for narrative clips with audio; Kling 3 for high-energy dynamic inserts. Full workflow at our Veo 3 course page and our Kling 3 course page.
For local business owners (restaurant, beauty, real estate)
Veo 3 as the single first tool. Native audio removes the need for a separate voiceover, and longer walk-throughs are assembled from several 8 s shots or lengthened with extend. After 2-3 months, add Runway Gen-4.5 Standard ($12/mo annually) for product shot precision. See our Sora 2 vs Veo 3 comparison if you are moving over from Sora.
For marketing managers in B2B companies
Veo 3 + Runway Gen-4.5 Pro ($28/mo annually). Veo for product presentations and case study videos with voiceover; Runway for precise product shots with prompt-driven camera moves and References. Combined cost around $50/month, less than a single day of freelance camera work. Workflow details at our Veo 3 course page and our Runway course page.
For professional filmmakers and agency creatives
Runway Gen-4.5 Max ($76/mo annually) + Veo 3.1 Quality. Runway as the precision tool for client-facing work (camera moves from the prompt, References, Aleph edits, native audio); Veo for dialogue scenes with lip-sync that Sora 2 used to handle. Recovered after one commercial ad project. See our Kling 3 vs Runway Gen-4 comparison if you are deciding on the motion-focused side of the stack.
For beginners with a budget under $15/month
Kling 3 Standard ($10/mo) as the single subscription, or Veo 3 pay-per-clip. If you have an NVIDIA GPU with 8 GB of VRAM or more, add free LTX 2.3 locally for testing. Step-by-step start guide at our Kling 3 course page.

Frequently Asked Questions
Does Sora 2 still work?
No. OpenAI closed the Sora app (sora.com, iOS, Android) on April 26, 2026 and shut down the Sora 2 API on September 24, 2026, with no successor. Third-party services that resold Sora through that API, such as fal.ai, stopped working too. If you have prompts written for Sora, the easiest move is to port them to Veo 3, which also generates dialogue with native audio.
Which AI video generator is best in 2026?
There is no single winner, it depends on your goal. For short social ads with dialogue and native audio, Veo 3 / 3.1 leads now that Sora 2 is gone. For precise camera control, product shots and character consistency, Runway Gen-4.5 is the pick. For dynamic motion at a low price, Kling 3 is the budget champion. For free local iteration on your own GPU, LTX. See the full decision matrix in the verdict section of this article.
Which AI video tool is cheapest?
The most affordable subscription is Kling 3 Standard at around $10/month. Runway Standard is $12/month billed annually or $15 month-to-month. Veo 3 through Kie.ai is pay-per-clip, roughly $0.30 per 8 s clip on the Fast tier. LTX 2.3 is free if you run it locally on an NVIDIA GPU.
What should I use instead of Sora 2?
For dialogue and native audio, Veo 3.1 is the closest replacement. Keep in mind that Veo generates 4, 6 or 8 s per generation (Sora went up to 20 s), so longer scenes are split into shots or lengthened with extend. For a cinematic look with precise camera work, choose Runway Gen-4.5, and for character motion, Kling 3.
Is Kling 3 suitable for professional advertising?
Yes, in specific niches. Kling 3 shines with dynamic motion: dance, sports, fitness, beauty with slow-motion hair. For premium luxury or fashion editorial campaigns choose Runway Gen-4.5 or Veo 3.1 instead. Kling is an excellent supporting tool in an agency workflow, less often the primary tool for high-budget cinematic projects.
Can I use multiple tools at the same time?
Yes, and that is the professional standard. A typical B2B workflow: Runway Gen-4.5 for key product shots, Veo 3.1 for dialogue scenes, Kling 3 for dynamic inserts, CapCut for the final edit. Each tool has its strengths; combining them in one workflow produces the best output. See the full multi-tool workflow in the AI video course.
Which tool handles native English audio best?
Veo 3.1 generates native audio with lip-synced dialogue and handles English cleanly. Runway Gen-4.5 has generated native audio and dialogue since its December 2025 update. Kling 3 generates native dialogue with lip-sync in English, Chinese, Japanese, Korean and Spanish. Sora 2 had strong native audio, but it has been shut down. Details on the Veo 3 course page.
Which AI video generator should a beginner start with?
For someone with no prior experience, start with Veo 3: either through a Google AI Pro subscription ($19.99/month) or pay-per-clip via Kie.ai. It gives fast results with native audio included. Second choice is Kling 3 Standard ($10/month) for tight budgets. Runway Gen-4.5 has a steeper learning curve; leave it for stage two. Full beginner workflow in the AI video course hub.
