Sora 2, Gen‑3, Veo 3: How do they compare, and how can I integrate them into my workflows?
2025 is a big year for AI videos; it feels like every week we are being treated to a new model. Open‑source models inside ComfyUI are constantly getting better, especially when being used inside the type of custom workflows Comfy is best for. However, for now, the most photorealistic results come from closed‑source systems like OpenAI Sora 2, Runway Gen 3, and Google Veo 3. That’s exactly why ViewComfy lets you use any of these models inside ComfyUI through the ViewComfy API node pack. Using ViewComfy also comes with the added benefit of being able to wrap workflows into shareable apps in just a few clicks.
Model comparison
Sora 2, Gen 3 and Veo 3 can all deliver stunning quality. Outside the technical details, your choice will often comes down to style preferences.
| Model | Headline strength | Audio | Duration / resolution |
|---|---|---|---|
| OpenAI Sora 2 | OpenAI emphasizes physically plausible motion and improved temporal consistency in short clips | Native, synchronized audio | Clip length & resolution not publicly specified yet |
| Runway Gen‑3 (Alpha / Turbo) | Shines for stylized looks and controlled camera language (dolly, crane, handheld), producing highly intentional motion. | No native support but can be used with lip‑sync or audio models | 5s or 10s generations at around 720p |
| Google Veo 3 (and Veo 3 Fast) | Cinematic coherence and temporal consistency | Native, synchronized audio | 4s, 6s or 8s at 720p or 1080p |
Practical tips
Plan before you generate
Closed‑source video can be pricey. A simple storyboard or some basic planning is an effective way to keep cost under control:
- Outline shots (beats, transitions, camera moves).
- Collect style refs (color, lensing, texture, wardrobe, props).
- Decide aspect ratio up front (16:9 vs 9:16) so you don’t regenerate.
Do the math: provider pricing is often per second of output. For example, an 8‑second clip can easily run a few dollars depending on tier/quality.
Prompt tips
Use explicit camera language:
- Subject & setting: “Golden‑hour street market; handheld close‑up on spices.”
- Camera: “dolly, crane, gimbal, handheld”
- Materials: “glass, velvet, brushed stee”
- Lighting : “soft key, rim, HDR speculars”
- Physics cues: “wind, inertia, collisions”
- Style guardrails: “Naturalistic grade; avoid neon saturation; minimal grain.”
How to integrate Sora 2, Gen 3, and Veo 3 into ComfyUI with ViewComfy
You can use all of these models with ViewComfy’s ComfyUI node pack. Veo 3 is available today, and as soon as APIs are released for Sora 2 and Gen 3 they will be added too. You can also choose from our growing library of other closed‑source models and APIs.
Another benefit is that you get central authentication and billing out of the box, which minimizes the number of subscriptions you need to juggle by consolidating access in one place. This makes it easier for teams to manage credentials and costs.
Once set up, you can wrap any workflow into a shareable app with the ViewComfy App Builder, exposing only the controls you want and sharing securely through built‑in user management.
The best part is you don’t have to pick a single model: access them all from one place, A/B test styles, and ship your best option as a ComfyUI‑powered app your designers will love.
