Free Google Cloud (Vertex AI) credits

Google Cloud's free trial gives new accounts a $300 credit to spend over 90 days on Vertex AI and the Gemini API — the most generous single AI credit available, though it needs a payment method.

The short answer

The Google Cloud $300 / 90-day trial runs Vertex AI and the Gemini API. For a no-card option, pair it with the Google AI Studio free tier.

Frequently asked questions

How much free credit does Google Cloud give?
New Google Cloud accounts get a $300 welcome credit to spend over 90 days across Google Cloud products, including Vertex AI and the Gemini API. A payment method is required, but you are not charged when the trial ends.
Can I use the $300 Google Cloud credit for AI?
Yes. The credit covers Vertex AI (which hosts Gemini and many other models, including Claude) and the Gemini API, making it one of the most generous ways to run hosted models for free.
Is the Google Cloud free trial the same as the always-free tier?
No. The $300 / 90-day trial credit is separate from Google Cloud’s always-free usage limits. For an ongoing, no-card Gemini option, see the Google AI Studio free tier.
