Sora 2
Sora 2 is OpenAI's flagship AI video model, generating cinematic-quality clips with industry-leading physics simulation, natural motion, and synchronized audio. The Sora 2 family spans a base model, a high-fidelity Sora 2 Pro tier, and a multi-shot Storyboard editor for structured narratives — all runnable as nodes on the Martini canvas.
Sora 2 is OpenAI's flagship video generation family, released September 30, 2025 as the successor to the original Sora. The base Sora 2 model handles text-to-video and image-to-video at 1080p with realistic lighting, reflections, water, and camera work, and its standout trait is physics simulation: objects fall, splash, bounce, and collide with believable momentum instead of the "dream logic" of earlier models. Sora 2 Pro raises fidelity with clarity control and 15-second clips, while the Sora 2 Pro Storyboard variant lets you define per-scene prompts, timing, and transitions for complete multi-shot sequences in a single generation. Sora 2 vs Google Veo and Kling 3: Veo leads on native dialogue/audio range and Kling 3 on talking-character lip-sync, while Sora 2 is the strongest on real-world physics and prompt-faithful storyboard control — which is exactly why fanning the same prompt across all three on one Martini canvas, then picking the winning take, beats committing to any single model. Note: OpenAI retired the standalone Sora consumer web and app experience on April 26, 2026 and is sunsetting the Sora video API on September 24, 2026; on Martini, Sora 2 remains available as a managed canvas node for as long as the upstream endpoint is served.

Get Started FreeFrequently Asked Questions
What is Sora 2 and how does it work?
Sora 2 is OpenAI's flagship AI video model, released September 30, 2025, that turns text prompts or input images into cinematic 1080p clips. It works by simulating real-world physics, lighting, and camera motion, so objects move with believable momentum and scenes stay coherent across the shot. On Martini you run Sora 2 as a node on the canvas and chain it into other video, audio, or 3D nodes.
Does Sora 2 simulate physics?
Yes. Physics simulation is Sora 2's defining strength — water splashes, fabric drapes, and rigid bodies fall, bounce, and collide with believable momentum instead of the floaty "dream logic" of earlier video models. This is why Sora 2 is a strong pick for product showcases and action shots where motion has to look physically plausible.
What is Sora 2 Storyboard?
Sora 2 Storyboard (the Sora 2 Pro Storyboard variant) is a multi-shot editor that lets you define per-scene prompts, timing, and transitions and render a complete multi-shot sequence in a single generation. Instead of stitching separate clips, you plan 3-5 scenes with consistent character descriptions up front, and Sora 2 produces the structured narrative in one pass.
Is Sora 2 still available in 2026?
On Martini, yes — Sora 2 remains available as a managed canvas node as of 2026. OpenAI retired the standalone Sora consumer web and app experience on April 26, 2026 and is sunsetting the dedicated Sora video API on September 24, 2026, so direct OpenAI access is winding down; Martini surfaces Sora 2 for as long as the upstream endpoint is served, alongside 50+ other video and image models.
What is the difference between Sora 2 and Sora 2 Pro?
Sora 2 is the base model for text-to-video and image-to-video at 1080p with strong physics. Sora 2 Pro raises fidelity with clarity control and extends clip length to 15 seconds, and the Sora 2 Pro Storyboard variant adds the multi-shot editor. A common workflow is to draft on base Sora 2, then re-render the winning prompt on Sora 2 Pro for final quality.
Can Sora 2 do image-to-video?
Yes. Sora 2 accepts an input image to anchor the opening frame, then generates motion, lighting, and camera movement from your text prompt. This makes it useful for animating a still concept frame or a hero product shot. On Martini you can feed an image node — from FLUX, Midjourney, or an upload — straight into a Sora 2 node.
How does Sora 2 compare to Google Veo and Kling 3?
As of 2026, Sora 2 leads on real-world physics simulation and prompt-faithful storyboard control, Google Veo leads on native dialogue and audio range, and Kling 3 is strongest for talking-character lip-sync. Rather than committing to one, Martini lets you fan a single prompt across Sora 2, Veo, and Kling nodes on the same canvas and pick the winning take.
