Frequently asked questions
How do AI credits work?
1,000,000 AI credits equal $1 of protected model cost. Each cloud request settles at the provider's actual cost ×1.20; when credits run out, cloud AI stops — no overdrafts and no surprise bills.
Do local models or my own API key cost credits?
No. Local AI models and bring-your-own-key providers never consume credits — only 77Fox cloud requests do.
Can I cancel or switch plans anytime?
Yes. Upgrades take effect immediately with prorated billing, downgrades apply from the next period, and a cancelled plan stays active until the end of the paid period.
