[Strengths] It supports 360p, 720p, 1080p, and 4k output, 16:9 or 9:16, and 3 to 10 second clips with native speech, music, and sound effects. [Best For] Highly recommended for: rapid prototyping, short social and marketing clips, concept visualization, and cases that need built-in audio at 1080p or 4k. [Limitations] Do NOT use this model if you need clips longer than 10 seconds, a starting image as the first frame (use Gemini Omni 1.1 Flash I2V), or edits to an existing video (use Gemini Omni 1.1 Flash V2V). [Routing] Choose this when the user wants a new video from text only. If they provide a starting image, use Gemini Omni 1.1 Flash I2V. For maximum cinematic control, choose Veo 3.1 T2V. ## OpenAPI ````yaml /media-model-api/google/google-t2v.json post /google/gemini-omni-1.1-flash-t2v openapi: 3.1.0 info: description: The text-to-video models API from Google (Veo series). version: 1.0.0 contact: name: Modellix Support email: support@modellix.ai title: Google Text-to-Video Models API servers: - url: https://api.modellix.ai/api/v1 description: The text-to-video models API from Google. security: - bearerAuth: [] paths: /google/gemini-omni-1.1-flash-t2v: post: summary: Gemini Omni 1.1 Flash T2V description: >- [Core Function] Gemini Omni 1.1 Flash T2V generates a short video with synchronized audio from a text prompt.
