Most developers may not know this.
OpenAI quietly sponsors up to 10 million free tokens every day if you enable data sharing in your API settings.
That’s roughly 5,000 pages of text daily, enough to power an entire product prototype or content engine — for free.
If your prompts don’t include sensitive data, this is the easiest way to run the GPT-5 API nearly cost-free.
How it works
Model TypeFree Tokens/Day (Tier 3–5 users)
Equivalent TextMini models (gpt-5-mini, 4.1-mini) -> 10M~5,000 pages
Main models (gpt-5, 4.1, o3) -> 1M~500 pages
For Tier 1–2 users, the limits are about 25% of that.
Activate in 3 Steps
1️⃣ Visit platform.openai.com → Settings → Organization → Data Controls
2️⃣ Under “Share inputs and outputs with OpenAI”, select Enabled for all projects
3️⃣ Click Save — your account is now enrolled
Your daily allowance refreshes automatically.
Why It Matters
For builders, that’s effectively free compute for:
- Rapid-fire idea testing
- Text generation pipelines
- Automated research or content workflows
Just remember: disable sharing for any project involving private or client data.
