No mainstream "unlimited" AI video plan is unlimited in the sense buyers assume. The limits exist, they are written down in the terms of service rather than on the pricing page, and they usually take the form of throttling rather than a hard stop. The clearest example is in Higgsfield's own terms, which state that unlimited generations run on a slower queue than credit-based ones, meaning the unlimited tier is deprioritised behind people paying per generation. That is not a complaint from a forum; it is the vendor's published contract, quoted below.
What the terms actually say
From Higgsfield's Terms of Use Agreement, read 2026-09-16:
"model usage under subscription tiers marketed as 'Unlimited' is subject to Company's fair-use limits and the dynamic speed and concurrency limitations described below"
"Company may restrict, suspend, throttle, or place on a slower processing queue usage that is automated or materially exceeds typical individual use, in order to protect Service quality for other users"
"Unlimited models operate on a dedicated processing queue, separate from the priority queue used for credit-based generations. During periods of high demand, generation speeds may vary and additional concurrency limits may apply."
"Processing speed and parallel generation capacity are not guaranteed and may dynamically adjust based on overall platform usage."
Read the third quote twice. Unlimited is not the premium lane. It is a separate, explicitly non-priority lane, behind the credit-based one. Buying unlimited can make your generations slower than buying credits.
To be fair to Higgsfield: this is disclosed, in writing, in the place contracts live. The criticism is not that they hid it. It is that "Unlimited" on a pricing page and "fair-use limits, throttling and a slower queue" in the terms are two different products, and most buyers only read one of them.
The three shapes "unlimited" takes
Queue-based unlimited. Generate as much as you want, wait as long as the queue says. Midjourney's Relax mode is the well-known version and is upfront about it: unlimited generations, with wait times that lengthen the more you have used recently. The honest version of this model.
Fair-use unlimited. Unlimited until an undisclosed threshold, then throttling. The threshold is not published, which means you cannot plan against it. This is the shape most complaints come from, because users discover the limit by hitting it mid-project.
Unlimited with caps on the axis you care about. Unlimited generations, but capped resolution, duration, or concurrency. Technically accurate, practically a different product.
What to check before buying an unlimited plan
Read the fair-use clause, not the pricing page. Search the terms for "fair use", "throttle", "queue", and "concurrency". Five minutes, and it is the only place the real product is described.
Ask whether unlimited runs on a different queue than paid credits. If yes, you are buying deprioritisation.
Ask what the daily ceiling is. If the vendor will not state a number, the number exists and they would rather you discovered it.
Check the resolution and duration attached to unlimited. Frequently lower than the credit path.
Test in week one, not week three. Throttling is usage-triggered, so a plan can feel unlimited for three days and then change. Run your realistic peak volume early while you can still get a refund.
Where we sit, and why we do not use the word
We sell credits, and the canvas is the free part. We do not offer an unlimited generation tier, and this article is a reasonable place to say why rather than to pretend it is a virtue.
Generation costs us money per call, on the same provider APIs everyone else uses. Any unlimited tier must therefore be funded by either throttling heavy users or by the light users subsidising them, and both approaches make the product worse in ways that are invisible at purchase. Credits are less exciting on a pricing page and they have one property that matters: you can see exactly what a clip costs before you run it, and we cannot quietly change your throughput after you have paid.
What is genuinely unlimited on our side: boards and collaborators. What is metered and stated: generation, from $19/month for 1,000 credits, with per-clip prices published. A 5-second Kling v3 clip with audio is 86 credits, an 8-second Veo 3.1 Lite clip is 54, and a Wan 3.0 clip starts at 24.
And one thing we verified before publishing this: we have no priority tiers, no relax mode, and no per-plan daily generation caps. Every generation runs at the provider's speed regardless of which plan you are on, because there is no slower lane to put anyone in.
FAQ
Is any AI video plan truly unlimited? Queue-based ones come closest, because the constraint is time rather than a hidden threshold. Nothing is unlimited in the sense of unconstrained throughput at full speed.
Why do unlimited plans get slower over time? Because the throttle is usage-triggered. The terms above describe exactly this: dynamic speed and concurrency limits that adjust to platform usage and to how much you have generated.
Is a credit plan better than unlimited? Better for predictability, worse for very heavy use at a fixed cost. If you generate constantly and can tolerate queueing, unlimited can be cheaper. If you need a clip now, credits buy that.
Read the fair-use clause before the pricing page. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
