Hello everyone!
In today’s article, I’m going to show you how to use Google’s Veo 3 video generation model completely for free. This powerful model has already seen wide applications in advertising, creative short films, and more.
At the end of this article, I’ll also introduce an online AI ad generation tool I developed, which allows you to easily create high-quality videos with Veo 3 — no technical skills required.
Let’s get started!
✅ How Free Access to Veo 3 Works
Google Cloud offers $300 in free credits to new users, which can be used to access various services — including the Gemini API.
Veo 3 is one of the models that can be accessed via the Gemini API.
So our strategy is simple: take advantage of the $300 free credits to generate videos using the Veo 3 model — completely free of charge.
✅Preparation Steps
A Google account (no regional restrictions)
A Visa credit card to link as a payment method
⚠️ Tip: One credit card can be used to verify multiple Google accounts.
So once the $300 credit on one account is used up, you can register a new account and continue — effectively achieving “unlimited free usage.”
✅ Sign Up for Google Cloud and Claim Your Free Credits
Switch to a U.S. IP node (since Gemini API keys are not available in regions like Hong Kong).
Search for “Google AI Studio” and go to the official website.
Log in with your Google account and click “Get API Key” in the upper right corner.
Check the terms and conditions → Accept → Create an API key.
Select the Google Cloud project you just created → Click Create → Copy and save your API key.
At this point, everything is ready.
If you’re a technical user, you can now directly use this key to access the Veo 3 video generation model in your application.

No coding skills? No problem!
I’ve developed an online video generation tool that lets you use Veo 3 simply by entering your own Gemini API key. It’s user-friendly, cleanly designed, and supports template-based quick video generation.
✅ How to Use It:
Open the website (link is in the comments or at the end of the article).
Enter your saved Gemini API Key → Click Save.
Choose a video template (mainly for ads and product showcases), and preview the effect.
Enter your prompt in the text box, for example:
“Freedom Gundam LEGO toy flies away after being opened.”Select the model: Keep Veo 3, and set the resolution to 720p.
Click “Generate Video” — wait around 1 minute for it to finish.
✅ After the video is generated, you can:
Download the video
Copy the prompt you used
