Everything educational stays free. Credits only apply to compute above the free tier. Tools show an estimate before you run and a summary after.
Credits are abstract units, not money. Estimates vary with input size, run time, and features.

What can consume credits
What £10 can typically do
When payments launch, the minimum top-up will be £10. In normal use, that should cover many medium runs that exceed the free tier, plus a smaller number of large runs. The exact number varies by tool and input size.
Using current settings, the free tier includes about 60s of server assisted compute per day. Above that, one credit covers about 10s.
Example estimates: 10 credits is roughly 3 standard runs (about 30s) or 0 heavy runs (about 2 minutes). These are estimates, not promises.
Purchase credits for compute above the free tier. Minimum purchase is £10. Credits are used only when you explicitly confirm a credit-consuming run.

Accuracy first
I avoid inflated claims about accreditation, endorsements, or compliance. Where evidence exists, it is linked for verification.
