What you can create with other leading models
Generate videos where characters speak, environments have ambient audio, and sound effects match the action - all created in a single generation pass. No separate audio recording, no lip-sync post-processing. HappyHorse 1.0 generates video and audio as one unified output.
HappyHorse 1.0 is a 15-billion-parameter AI video model. It's the first model to jointly generate video and audio in a single forward pass, producing synchronized dialogue, sound effects, and ambient audio alongside the visuals. It debuted at #1 on the Artificial Analysis blind-test leaderboard in April 2026.
HappyHorse 1.0 is developed by an independent research lab. The model is open-source with a commercial license.
Most AI video models generate silent video, requiring separate audio tools for voiceover and sound design. HappyHorse 1.0 generates video and audio together in one pass - dialogue, ambient sound, music, and lip-synced speech are all produced as a unified output. It also supports 7 languages natively, more than any other video model.
HappyHorse 1.0 generates native lip-synced audio in 7 languages: English, Mandarin, Cantonese, Japanese, Korean, German, and French. Each language includes natural accent and dialect support. Audio is generated alongside the video, not dubbed in post.
HappyHorse 1.0 generates native 1080p video in clips of 5–8 seconds. It supports multiple aspect ratios: 16:9 (landscape), 9:16 (portrait), 4:3, 21:9 (ultrawide), and 1:1 (square). All outputs include synchronized audio.
HappyHorse 1.0 is available in three Picsart tools: AI Video Generator (direct text/image-to-video with native audio), AI Playground (open creative experimentation), and Flow (automated multi-step video pipelines). Picsart is an official launch partner.
Access to HappyHorse 1.0 depends on your Picsart plan. It's available across AI Video Generator, AI Playground, and Flow, with availability varying by subscription tier. Check Picsart pricing for current details.
