Veo 3.1 Lite is Google's most cost-effective video generation model, launched March 31, 2026. Available via the Gemini API and Google AI Studio, it supports Text-to-Video and Image-to-Video, generates clips in 4-, 6-, or 8-second durations at up to 1080p resolution, and costs approximately $0.05 per second of video on Vertex AI — less than half the price of Veo 3.1 Fast. The model is aimed at developers building high-volume video applications that need fast iteration at lower cost. It supports both landscape (16:9) and portrait (9:16) aspect ratios, making it suitable for web and mobile content pipelines. Access is via the paid tier of the Gemini API and Google AI Studio. Veo 3.1 Lite positions as the production-grade middle tier in Google's Veo lineup — cheaper and faster than the flagship, still capable of professional-quality output. It's the first Google video model widely accessible to developers through standard API pricing rather than enterprise contracts.

HappyHorse 1.0 is a 15-billion-parameter open-source video generation model that generates 1080p video with natively synchronized audio in a single inference pass. It appeared on April 10, 2026 under an anonymous label — then within 48 hours topped the Artificial Analysis Video Arena, beating Sora 2 Pro, Seedance 2.0, and Kling 3.0 in blind side-by-side comparisons. It was subsequently revealed to be from Alibaba's Taotian Group. What separates HappyHorse from existing open-weight video models is the native audio generation: most video models generate silent clips and require separate audio post-processing. HappyHorse outputs both in a single pass, dramatically simplifying local production workflows. The model is fully open with commercial use rights. The anonymous launch strategy was deliberate — it let the model win on merit before being associated with a Chinese tech giant. For the local video generation community, this is the equivalent of Stable Diffusion's arrival in the image space: free, open, self-hostable, and suddenly competitive with the best commercial offerings.
Reviewer scorecard
“At $0.05 per second, a 30-second video costs $1.50. That changes the unit economics for video apps completely. Vertex integration means it fits existing GCP pipelines without new infrastructure. If quality holds at scale, this is the API to build on for high-volume use cases.”
“This is the Stable Diffusion moment for video. Open weights, 1080p, native audio, commercial license — every local video pipeline just got a massive upgrade. The fact it beat Sora and Kling in blind testing is wild. Ship immediately.”
“Google's Veo lineup is a naming disaster — Veo 2, Veo 3, Veo 3.1, Veo 3.1 Fast, Veo 3.1 Lite. Classic Google product fragmentation. Also, an 8-second maximum duration is still very limiting for real content workflows. Runway and Kling remain ahead on duration and creative control — don't abandon them yet.”
“Anonymous launch by a major corporation is a PR maneuver, not a trust signal. We don't know the full training data provenance, which matters for commercial use. Running 15B parameters locally requires serious hardware — this isn't for most developers without a beefy GPU setup.”
“Sub-cent-per-second video generation from a tier-1 cloud provider is a pricing threshold moment. When video gen drops below $0.01/sec from a major provider, it'll be embedded in every CMS. We're one model generation away from that point, and Veo 3.1 Lite is the bridge.”
“We just crossed a threshold: open-source video generation is now competitive with the frontier closed models. The self-hosting video production market is about to explode. Every creative studio, game developer, and indie filmmaker will want to run this locally within six months.”
“Generating hundreds of short-form video variations for A/B testing at $0.05/sec is viable for mid-size creators and agencies. The portrait mode support for 9:16 shows Google is actually thinking about real creator workflows, not just enterprise demos.”
“Native audio sync in a single inference pass is the feature I've been waiting for. Current workflows of generating video, then separately syncing audio, then editing, are painful. HappyHorse collapses that into one step. For YouTube and social content creators, this is transformative.”
