Gemini Omni Flash API: Kie AI's video-generation model, one key away
Gemini Omni Flash via the ApexApi gateway
Gemini Omni Flash is Google's conversational video generation model. It turns a text prompt into a 3-10 second 720p clip at 24 fps with a generated audio track included on every render. Built on the same Omni model that powers video editing in Gemini, it is tuned for fast turnaround and cinematic camera direction from plain-language prompts. Call it through ApexApi's unified, OpenAI-compatible API with one `ak-` key, alongside every other model in the catalog. Pricing is $0.152–$1.37/sec per second, billed pay-per-use from your credit balance with no subscription.
Gemini Omni Flash is served through ApexApi's unified, OpenAI-compatible API. One key, one format, with smart routing and automatic failover. Provider: Kie AI.

How do I call Gemini Omni Flash through ApexApi?
Create an ApexApi key, point your client at https://api.apexapi.dev/v1, and POST to /v1/videos/generations with the model set to `google/gemini-omni-flash/text-to-video`. The API is OpenAI-compatible, so an existing OpenAI SDK works once you change the base URL and key.
How much does Gemini Omni Flash cost on ApexApi?
$0.152–$1.37/sec, billed per second with no subscription or minimum. The exact figure is shown before you generate, so nothing is charged against a price you have not seen.
What do I send to Gemini Omni Flash?
This variant takes a text prompt on its own, with no image required. The other variants of the same model accept different inputs, so pick the slug that matches what you already have.
What should I use instead of Gemini Omni Flash?
From the same maker, Veo 3.1 Fast costs less for lighter work and Google Veo 3 is the step up when this one falls short. Switching is one string: both run on the same endpoint and the same key, so there is nothing to re-integrate.
