Free-tier types: long-term free tier vs signup credit vs periodic reset vs limited-time

Updated 2026-11-13 · Table data from vendor official pages

Short answer: free allowances come in four shapes — long-term free tiers (no end date, rate-limited calls), signup credits (one-time, with an expiry), periodic resets (re-issued daily, weekly, or monthly), and limited-time campaigns (a fixed end date). The shape decides the validity, the rate limits, and what happens when it runs out. All 43 verified offers are grouped below.

How to tell which shape an offer is

Look at each offer’s “cadence” and “ends” fields: cadence “ongoing” means a long-term free tier; cadence “one-time” means a signup credit — check the validity in the allowance wording; cadence “daily / weekly / monthly” means a periodic reset — check the reset time and whether unused amounts roll over in the “reset” field; an “ends” date means a limited-time campaign, removed after expiry.

Whether running out costs money depends on the vendor: some stop, some switch to pay-as-you-go. See FAQ Q10 — and before claiming, confirm on the vendor’s official page whether there is a “stop when exhausted” type switch.

FAQ

Do unused periodic-reset allowances roll over?

Almost never. For example, ModelScope’s 250 magic particles per day state “unused credits do not roll over”, WorkBuddy’s 500 credits state “unused credits expire at month end”, and the Kiro student plan states “no rollover across months”. Unless the allowance wording explicitly says it rolls over, assume it does not.

Does the allowance survive after a limited-time campaign ends?

Limited-time allowances follow the campaign end date — for example, WorkBuddy’s Hunyuan Hy4 campaign ends 2026-11-15. Expired campaigns no longer apply.
