Feature comparison by criteria

The situation as of June 2026

This is not a normal comparison page. One of the two products being compared no longer exists in a usable form for most readers.

OpenAI discontinued the Sora web and app experience on April 26, 2026. The Sora API (models sora-2 and sora-2-pro) continues running until September 24, 2026, after which it is fully shut down. If you landed on this page because you are evaluating AI video tools right now, the decision is already made: use Veo 3.1.

The only readers still evaluating Sora are existing API integrators managing a migration window.

That said, this page still has real value. It answers three things: what Sora 2 actually delivered before shutdown, what Veo 3.1 offers today and how to access it, and how to think about AI video generation quality when third-party review data barely exists for either product.

Output quality and what the benchmark data says

Neither Sora 2 nor Veo 3.1 has a G2 or Capterra review corpus worth citing. This is not an oversight on our end. Both products were (or are) primarily direct-to-consumer AI tools without a meaningful presence on B2B software aggregators.

The quality signal for this comparison comes from three places: Google DeepMind’s published benchmarks, hands-on creator community reports from when Sora’s app was live, and the technical capability specs available from both vendors.

Google’s published benchmark compared Veo 3.1 against other leading video generation models in 364 side-by-side human rater evaluations at 1280x720 resolution. Google self-reports that Veo achieves leading scores for overall preference and visual quality in that benchmark.

The fine print is relevant: the comparisons were done without audio except for the “Overall Preference” metric, and the benchmark was last updated in October 2025. Take vendor-run benchmarks as directional, not definitive.

On the Sora side, the creator community that used the app consistently praised prompt adherence, physics simulation, and camera control. A 20-second clip of fluid dynamics or a character walking through a consistent environment was where Sora outperformed many alternatives.

The gap was less about raw realism and more about maintaining consistency across a scene over time.

Veo 3.1 addresses exactly those areas. The reference-image system (up to 3 reference images per prompt) lets you anchor a character or product’s appearance across multiple generated clips. The first-and-last-frame interpolation gives you precise compositional control.

These are the features that matter for serious creative production work, and they are live today.

Pricing reality

The pricing table has a lopsided story in June 2026.

Sora 2 API pricing was never officially documented on the standard OpenAI API pricing page before or after the app shutdown. The API endpoint (api.openai.com/v1/videos) still accepts sora-2 and sora-2-pro models with clip durations of 4, 8, or 12 seconds and resolutions up to 1792x1024. But OpenAI has not published a per-second or per-video USD price on any public page as of June 20, 2026. If you have an existing Sora API integration, your billing history will show the rate you were charged. Do not count on that rate continuing; the API shuts down September 24, 2026 regardless.

Veo 3.1 pricing is fully published and live. There are two paths:

Consumer access via Google Flow:

Developer API via Gemini:

An 8-second clip at Veo 3.1 Standard costs $3.20 at 1080p, or $4.80 at 4K. At Veo 3.1 Fast it is $0.96 at 1080p. For a developer testing at 50 clips per month, that is $48 to $160/month on the Standard tier before any subscription. The Lite tier brings that to $20/month for 50 clips at 720p.

The hidden variable on Google Flow’s credit system: credits are consumed per generation, not per second. As of this writing, the credit cost per video is not documented precisely on the pricing page, so expect to test your actual consumption before committing to a plan tier.

What the Sora API actually delivered

Since the consumer app is gone, the only place Sora 2 specs are still documented is the OpenAI API reference. The API supports:

• Models: sora-2 (default) and sora-2-pro
• Durations: 4, 8, or 12 seconds
• Resolutions: 720x1280, 1280x720, 1024x1792, 1792x1024
• Input reference: a single image to guide generation
• No 4K output; maximum resolution is approximately 1080p landscape

The 12-second clip length was a real differentiator. Veo 3.1 tops out at 8 seconds per generation (though you can extend repeatedly to reach up to 148 seconds). For builders who needed a longer native clip in a single generation call, Sora’s API was the only way to get it in this quality tier.

The sora-2-pro model was positioned as higher quality but slower and more expensive. Neither the quality uplift nor the pricing differential is publicly documented in verifiable USD figures as of this writing.

What Veo 3.1 actually delivers

Veo 3.1 is the current production version. Here is what it does:

Resolution and duration. 720p, 1080p, or 4K output. At 720p you can generate 4, 6, or 8-second clips. At 1080p and 4K, generation is locked to 8 seconds. Frame rate is 24fps across all variants.

Native audio. Always on for Veo 3.1, Veo 3.1 Fast, and Veo 3.1 Lite. The model generates synchronized sound effects, ambient audio, and dialogue from text cues. You can specify dialogue in quotes, describe sound effects explicitly, and describe ambient soundscapes. Sora 2 also had native audio when the app was live, so this is parity, not advantage, on paper. The practical advantage is that Veo’s audio is accessible and testable right now.

Reference image system. Veo 3.1 accepts up to three reference images to guide a generated video’s content. This is the biggest functional upgrade over Veo 3. You can hold a character’s face, a product’s appearance, or a costume consistent across multiple generated clips. The Sora API only accepted a single input_reference image.

Video extension. Extend a Veo-generated clip by up to 7 seconds per extension call, up to 20 times, for a maximum of 148 seconds of continuous output. Works at 720p only. Generated videos are retained for 2 days (the storage timer resets when you reference a clip for extension).

Aspect ratios. 16:9 (landscape) and 9:16 (portrait). Portrait (9:16) is specifically useful for short-form social content. Sora 2’s API offered more resolution flexibility but did not specifically call out portrait-first social formats.

Where Veo 3.1 wins outright

Product continuity. Veo has a roadmap, an active engineering team at Google DeepMind, and three distribution channels: Google Flow for consumers, Gemini API for developers, and Vertex AI for enterprise. There are no signs of discontinuation. The model went from Veo 2 to Veo 3 to Veo 3.1 over roughly 12 months, which is aggressive for a video generation model.

Free tier that actually works. Google Flow’s free tier gives 50 daily credits to any Google account holder. You can generate real Veo 3.1 output today with no credit card and no subscription. The Sora app never had a free tier; it was always gated behind ChatGPT Plus at a minimum.

Reference image system. Three simultaneous reference images for character and product consistency beats Sora 2’s single input reference. For marketing teams building brand-consistent video assets, this is a meaningful workflow difference.

SynthID provenance. Every Veo-generated video carries an invisible SynthID watermark, verifiable via Google’s verification platform. This is better AI provenance than most models offer and matters for brands worried about deepfake liability and content authenticity for regulated industries.

Vertex AI for enterprise. Veo is available on Google Cloud’s Vertex AI, which means enterprise data governance, VPC isolation, and the ability to sign a DPA. OpenAI did not offer a Sora enterprise path before shutdown.

Where Sora 2 had the edge

Being honest about this matters for any reader comparing historical context.

12-second clip length. The single biggest functional edge Sora had over current Veo. A 12-second native clip in one API call is meaningfully different from 8 seconds, particularly for narrative content that needs a complete scene without post-generation stitching.

Physics simulation and scene consistency. When the app was live, Sora’s handling of fluid dynamics, rigid body interactions, and long-shot camera motion was the strongest available. Users documented examples of cloth physics, water behavior, and structural collapse animations that held up across the full clip duration. Veo 3.1 is competitive here but not clearly ahead on this specific dimension.

Sora-2-pro quality ceiling. The pro variant was available for high-stakes production work. There is no publicly documented equivalent at the same quality level on Veo’s Fast/Lite tiering; the Veo 3.1 Standard tier is the quality-optimized variant.

None of these advantages matter if the product is shutting down. They are context for understanding what the state of the category was, and for calibrating expectations when evaluating Veo 3.1 against what Sora delivered.

Commercial use rights and watermarking

This section matters for any brand or agency building on AI video.

Veo 3.1. Google Flow’s Terms of Service permit commercial use of generated content, subject to the standard prohibitions (no CSAM, no harmful content, etc.). All Veo-generated videos are watermarked with SynthID. The watermark is not visible to the human eye but is detectable via Google’s verification tools. You cannot remove it. For most commercial use cases, an invisible provenance watermark is an asset rather than a problem, but confirm with your legal team for regulated industries or broadcast work.

Sora 2 (legacy). OpenAI’s usage policies permitted commercial use of Sora outputs when the app was live, subject to the same standard prohibitions. The policy situation for any output generated via the API before September 24, 2026 should be confirmed directly with OpenAI legal, particularly if those outputs are being used commercially after the shutdown date.

Integration depth and API access

For any developer building a production application, the Vertex AI path gives Veo enterprise-grade infrastructure that Sora never offered. If you were on Sora’s API for a consumer application, the Gemini API is the direct swap.

Security and data handling

Veo on Gemini API. On the paid Gemini API tier, Google does not use your content to improve its products by default. Generated videos are stored for 2 days and then deleted. The API is accessible via standard OAuth or API key authentication.

Veo on Vertex AI. Full enterprise data governance, regional data residency, VPC integration, and the ability to sign a Google Cloud DPA. SOC 2 Type II coverage inherited from Google Cloud. This is the path for any enterprise team with a compliance requirement.

Sora (historical). OpenAI’s API operated under their standard Enterprise data policy, but no enterprise SLA or dedicated data residency path was ever documented for the Sora API specifically.

Switching cost and vendor lock-in

If you are currently on the Sora API, you have no choice but to migrate. The migration path is:

1. Replace api.openai.com/v1/videos calls with Gemini API veo-3.1-generate-preview calls.
2. Map durations: Sora’s 4s and 8s map directly. Sora’s 12s becomes two Veo 3.1 generations stitched via video extension.
3. Map resolutions: Sora’s 1280x720 maps to Veo 3.1 720p or 1080p landscape. Portrait formats map to Veo’s 9:16.
4. Replace sora-2-pro quality with veo-3.1-generate-preview standard variant.
5. Add SynthID watermarking considerations to your content pipeline.

Expect 2-4 weeks for a clean migration with API testing. The main friction points are audio prompt formatting (Veo’s audio is controlled via text cues inside the main prompt, not a separate parameter) and the 8-second clip ceiling requiring a video extension call for anything longer.

Vendor viability

Veo / Google DeepMind. Google is financially committed to AI media generation at scale. Veo went from internal research to commercial availability with three model versions in under two years. The Google Flow consumer app, the Gemini API path, and Vertex AI enterprise access represent three distinct monetization channels, all active. DeepMind published benchmark data as recently as October 2025. The risk of Veo being discontinued is low given Google’s broader AI strategy, though “Preview” API status means the exact model IDs may change.

Sora / OpenAI. OpenAI decided to discontinue Sora rather than continue investing in it as a standalone product. The stated reason, per the help center article, is the April 26, 2026 shutdown without further explanation. OpenAI clearly prioritized other products (GPT-5.5, Codex, and the agentic stack) over video generation as a consumer surface. There is no public statement about a Sora replacement from OpenAI as of June 20, 2026.

Best-for matrix

Not for you

Veo 3.1 is the wrong tool if: you need clip lengths over 8 seconds in a single native generation (video extension works but adds latency), if you need deterministic outputs (the seed parameter in Veo 3 is gone in 3.1), or if your workflow is already on Runway, Kling, or another platform where switching cost outweighs quality differences. The free tier is genuinely usable for testing before committing.

Sora 2 is the wrong tool if: you are starting a new project, a new integration, or a new creative workflow today. Full stop. The only remaining Sora use case is completing work inside existing API integrations before September 24, 2026.

The verdict

Pick Veo 3.1. That is the whole verdict.

Sora 2 was a compelling product when it was live. The physics simulation and the 12-second clip length genuinely set it apart from alternatives. But “was compelling” does not help anyone in June 2026. The app is gone, the API ends September 24, and OpenAI has not announced what replaces it.

Veo 3.1 is live, actively improved, and available at every price point from free to enterprise. The native audio is on by default, the reference image system covers the character-consistency problem that video creators have been asking for since day one, and the Vertex AI path covers the enterprise compliance requirements that Sora never addressed.

The category is moving fast. Runway Gen-4, Kling 2.0, and others are real alternatives worth testing alongside Veo. But if the question is specifically Sora vs Veo, the answer has been made by OpenAI’s own product decision. Use Veo 3.1.
