Who qualifies
New Google Cloud users with an @gmail.com Google Account
The catch
Only for new Google Cloud users with a @gmail.com account. Separate from the $300 Google Cloud Free Program. Existing Google Cloud users, or anyone who enables billing, lose the 90-day free tier and move to paid. Limited to the APIs and quotas express mode supports.
What you get
- Free for up to 90 days within set quotas
- No billing information needed to sign up
- Includes an API key and Agent Studio for prompt testing
- Add a billing account any time to raise quotas

Google for Startups Cloud Program — AI tier
VC-backed startups building on Gemini can get up to $350,000 in Google Cloud credits over two years.
- Startups that raised Pre-Seed/Seed within 5 years (or Series A within 12 months), founded within 5 years, built on Gemini, with under $5,000 in prior Google Cloud credits
- Credits over 2 years
- Catch: Eligibility is at Google's discretion. Third-party models (e.g. Claude on Vertex) are billed directly and not covered by credits. Credits are tied to actual spend, not paid upfront.

Max and Team subscribers get $100-$200/month (Team: up to $500 pooled) of Claude API credits, no card needed on the Console.
- Max 5x, Max 20x or Team plan subscribers (Free, Pro and Enterprise are not eligible)

OpenAI API — free daily tokens for sharing traffic
Opt in to share API traffic with OpenAI and eligible orgs get up to 1M-10M complimentary tokens a day on listed models.
- Eligible API organizations only; the org owner must opt in on the data sharing settings page
- Daily quota, by model group and usage tier
- Catch: Your prompts and outputs are shared with OpenAI and can be used to improve its models. Not every org is eligible (you only see the offer if you are), you need a positive account balance, and Zero Data Retention accounts cannot opt in. Fine-tuning, evals and tool use are excluded; overage is billed at normal rates.
