[Strengths] Known for its distinctive cinematic style and fluid motion priors from the Veo 2 era. Maintained for backward compatibility. [Best For] Existing legacy integrations and workflows that strictly depend on this specific model version's quirks. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Veo 3.1 I2V. ## OpenAPI ````yaml /model-api/google/google-i2v.json post /google/veo-2-i2v openapi: 3.1.0 info: description: The image-to-video models API from Google (Veo series). version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Google Image-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The image-to-video models API from Google. security: - bearerAuth: [] paths: /google/veo-2-i2v: post: summary: Veo 2 I2V description: >- [Core Function] Veo 2 I2V is an older generation image-to-video model.
