[Strengths] It provides high-quality video editing capabilities (with or without reference images) within the highly optimized HappyHorse architecture. [Best For] Highly recommended for: fast, high-quality video modifications, especially when the user explicitly requests HappyHorse. [Limitations] May lack the deep instruction-based logical replacement mechanics of Wan 2.7 Video Editing. [Routing] Route to this model when the user explicitly requests 'HappyHorse' for their video editing task. ## OpenAPI ````yaml /model-api/alibaba/alibaba-v2v.json post /alibaba/happyhorse-1.0-video-edit openapi: 3.1.0 info: description: The video-to-video models API from Alibaba. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Alibaba Video-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The video-to-video models API from Alibaba. security: - bearerAuth: [] paths: /alibaba/happyhorse-1.0-video-edit: post: summary: HappyHorse 1.0 Video Edit description: >- [Core Function] HappyHorse 1.0 Video Edit is a streamlined video editing model.
