AI video in 2026: sound, vertical formats and a fast-changing platform map

The frontier has moved beyond image quality

For the first wave of generative video, the headline was whether a system could produce a believable moving image at all. The new competition is broader: can it coordinate image, motion, dialogue, sound, reference identity, aspect ratio and delivery quality inside one experience?

OpenAI described Sora 2 as a video-and-audio model with synchronised dialogue and sound effects. Google describes Veo 3.1 as supporting more expressive image-guided clips, native vertical generation and higher-resolution output through products including Flow, Vertex AI and the Gemini API.

Native audio changes the meaning of generation

Sound is not a decorative layer. Dialogue timing, room tone, impact, rhythm and silence determine how an audience reads an image. When a model generates sound alongside motion, the unit being created moves closer to a complete audiovisual event.

That does not make every output finished or trustworthy. It expands the creative surface and the safety problem at the same time. Voice, music imitation, misleading speech and consent become central product questions rather than downstream concerns.

Vertical video is now a first-class format

Google's January 2026 Veo 3.1 update added native vertical support and positioned it across consumer, creator and enterprise surfaces. This reflects a larger market reality: mobile-first video is no longer a secondary crop of a widescreen master.

The significance is cultural as well as technical. AI-video systems are being shaped by the formats in which billions of people encounter stories, products, personalities and news. Pumpkin AI expects format intelligence—how a piece is experienced—to matter as much as raw generation quality.

• Audio-native generation expands both creative possibility and rights risk.
• Multi-reference control is becoming a visible competitive layer.
• Vertical output is moving into core model and platform design.
• Resolution claims matter only when the service and delivery path are actually available.

Capability and product availability are not the same thing

The market is moving quickly enough that a widely discussed capability can change access model, interface or availability within months. OpenAI's current Sora pages state that the Sora product was no longer available from 26 April 2026, even as its earlier Sora 2 release remains an important capability milestone.

This is a useful warning for the whole sector. A model announcement is not a permanent production guarantee. Buyers and creators need to separate research capability, public product, regional access, commercial terms and the version that is available on the day a decision is made.

AI video is becoming an ecosystem, not one magic model

The worldwide shift is toward connected ecosystems: generation inside consumer apps, APIs, enterprise platforms, social formats and editing environments. Competition is increasingly about where a model can be used, what evidence it accepts, what it reveals about provenance and how reliably it fits real communication needs.

Pumpkin AI will report these changes as industry intelligence—not as a public recipe for production. The useful question is what a new capability changes for audiences, brands, filmmakers and culture, and what remains uncertain after the launch headline fades.
