You can get 2.5M free GPT tokens a day via OpenAI's data-sharing program
crasspuk · reddit · 2026-11-11
OpenAI's opt-in data-sharing program grants free daily tokens: on the Build tier ($5 of credit purchased), that's 2.5M tokens/day across mini models (gpt-5.6-luna, gpt-5.6-terra, gpt-5.4-mini, gpt-5-mini, o4-mini, codex-mini and more) plus a separate 250K/day for larger ones (gpt-6-astra, gpt-6-sol, gpt-5.5); Launch and Grow tiers get 10M and 1M. Resets at 00:00 UTC.
Enable under Organization → Data controls → Sharing → Share inputs and outputs with OpenAI.
Two caveats: shared traffic may train models, so keep confidential data out; and nothing hard-stops you at the limit — overage is billed at standard rates, and the request that pushes you over is billed in full. The author hit this with a coding agent and built an open-source MIT guard (opencode plugin) that meters daily usage per pool, warns at 85%/95%, and refuses requests that would cross the free limit, plus a SPEC.md to add the same check to any app.
