[Strengths] It accepts an images array for reference-led motion, aiming to preserve identity, wardrobe, and product look across the clip while supporting flexible duration and optional native audio. [Best For] Highly recommended for: character-consistent animation from design sheets, multi-reference product shots, comic or IP look locking, and I2V tasks where a single first frame is not enough. [Limitations] Do NOT use this model for simple one-image animation when cost or speed is the priority; use Kling V3 I2V or Kling V3 Turbo I2V. Do NOT use it when the primary input is text only; use Kling V3 Omni T2V or Kling V3 T2V. Do NOT use it for lip-sync avatar from audio alone; use Kling Avatar. [Routing] Choose Kling V3 Omni I2V when the user asks for Omni, multiple references, or strict visual consistency from images. Prefer Kling V3 I2V for standard single-image high quality; prefer Kling V3 Turbo I2V for fast or cheap single-image jobs. ## OpenAPI ````yaml /model-api/kling/kling-i2v.json post /kling/kling-v3-omni-i2v openapi: 3.1.0 info: description: The image-to-video models API from Kling AI. version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Kling Image-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The image-to-video models API from Kling AI. security: - bearerAuth: [] paths: /kling/kling-v3-omni-i2v: post: summary: Kling V3 Omni I2V description: >- [Core Function] Kling V3 Omni I2V is a multimodal image-to-video model that animates from one or more reference images with stronger subject and style consistency.
