Schema

[Core Function] Veo 3.1 Fast I2V is a high-speed image-to-video model. [Strengths] It quickly animates starting images at 1080p, optimized for low latency. [Best For] Highly recommended for: rapid prototyping and quick social media visual iterations. [Limitations] Do NOT use this model for the absolute highest visual fidelity or 4K output. [Routing] Choose this model when the user emphasizes 'fast' or 'quick' animation.

  • google/veo-3.1-fast-t2v: [Core Function] Veo 3.1 Fast T2V is a high-speed text-to-video model. [Strengths] It is heavily optimized for fast generation, delivering video content with natively synchronized audio at 1080p quickly. [Best For] Highly recommended for: rapid prototyping, quick visual iteration, and high-volume background video generation. [Limitations] Do NOT use this model if you require 4K resolution or maximum artistic detail. [Routing] Choose this model when the user emphasizes ‘fast’, ‘quick’, or ‘rapid’ video generation.
  • google/veo-3.1-t2v: [Core Function] Veo 3.1 T2V is Google’s state-of-the-art cinematic text-to-video engine. [Strengths] It natively generates 4K professional-grade video output with natively synchronized audio and supports complex camera movements. [Best For] Highly recommended for: high-end creative storytelling, cinematic short films, and experimental video production with sound. [Limitations] Do NOT use this model if you need instant/real-time generation, as 4K video rendering takes time. [Routing] Use this model by default for all high-quality text-to-video requests on the Google platform.
  • google/veo-3.1-i2v: [Core Function] Veo 3.1 I2V is Google’s cinematic image-to-video generation model. [Strengths] It generates high-fidelity 4K video from a starting image. It supports advanced features like first-and-last frame conditioning and referencing up to three images. [Best For] Highly recommended for: animating concept art, creating cinematic transitions between images, and high-end video production. [Limitations] When using first+last frame or reference-only modes, the duration parameter must strictly be 8. Negative prompts are not supported in reference-only mode. [Routing] Use this model by default for high-quality image-to-video tasks or when multiple reference images are provided.
  • google/veo-3.1-lite-t2v: [Core Function] Veo 3.1 Lite T2V is a balanced text-to-video model. [Strengths] It provides a good balance between generation speed and visual quality, still supporting the advanced architecture of the 3.1 series. [Best For] Highly recommended for: general video content creation and social media posts where 4K is not strictly necessary. [Limitations] Do NOT use this model for the absolute highest cinematic fidelity (use the standard Veo 3.1 instead). [Routing] Route to this model for standard, everyday video generation tasks.
  • google/veo-3.1-lite-i2v: [Core Function] Veo 3.1 Lite I2V is a balanced image-to-video model. [Strengths] It offers a middle ground between speed and quality for animating images. [Best For] Highly recommended for: general image animation and web-ready content. [Limitations] Do NOT use this model if you need 4K resolution. [Routing] Use this model for standard image animation requests.
