Where Your Credits Go in One Episode

Quick answer: Five steps cost credits: reading the script, generating setup images, generating each episode's storyboard, shooting each segment of video, and compositing the episode. Editing, previewing, matching voices, switching versions and re-reading what you already have are all free. Video is by far the largest line, and its price is per second of finished footage.

The five charges

Reading the script — 4 credits per 3,333 characters, charged once. It produces the characters, locations, props and episode breakdown.

Setup images — 7 credits each on the default tier. Your account gets 15 free ones to spend across any dramas you have had read.

Storyboard — 1 credit per 333 characters of that episode's share of the script, charged per episode. Regenerating costs the same as the first time.

Video — from 10 credits per second of finished footage, depending on the model tier you pick. Regenerating a segment charges again.

Compositing — 1 credit per second of the finished episode.

A worked example

A ninety-second episode shot on the cheapest tier and composited comes to about 990 credits. The storyboard for that episode is a small fraction of it, and the script read is paid once for the whole project rather than per episode.

The shape of the bill is always the same: video dominates, everything else is rounding. That is why the free allowance on a first project covers the cheap steps — they are where you find out whether the expensive one is worth running.

Freeze, then charge

When you start something, its cost is frozen — held aside, not spent. If it succeeds the frozen amount is charged. If the model call fails, it is released back to you.

Every one of these movements is written to a ledger you can read from the credits panel in the top bar, so a balance that looks wrong can always be traced to a specific line.

What happens when something goes wrong

What refunds automatically: a request the model never received (a bad parameter, a reference image we could not fetch), the model being rate-limited or busy, and a clip stopped by content moderation. A generation you cancel before it starts also refunds.

What does not refund automatically: a timeout, a 5xx or a network error mid-call. We cannot tell from our side whether the model ran and we were already billed, so the credits stay frozen rather than being either charged or given back, and a person settles it. A generation already running when you cancel is charged — the call has been made.

If a video is produced but we fail to deliver it to you, the amount stays frozen rather than being charged, and it is settled by hand. You are not billed for something you did not receive.

Discounts apply when you buy, not when you spend

The discount is on the buying side, not the spending side. A membership discount and a promo code both come off the price of a credit pack or a subscription, and the combined discount is capped. What a generation costs in credits is the same number for everyone.

The price on a button and the amount actually taken come from the same calculation, so the number you agreed to is the number you pay.

FAQ

Why is video so much more expensive than everything else?

Because it is the only step whose upstream cost scales with the length of what you make. Text and image steps are one call each; video is one call per segment, per second.

Do I pay again if I regenerate a segment?

Yes, at the same price. The earlier version is kept, so you are paying for an alternative, not a replacement.

What if a generation fails halfway?

An upstream failure is refunded. If a video was produced but could not be delivered to you, the amount stays frozen and is settled by hand rather than charged.

Does membership make generating cheaper?

No — it makes buying credits cheaper, and it gives you a monthly credit allowance. A generation costs the same number of credits for everyone. The price on the button is always what is actually taken.

Can I see where my credits went?

Yes — the credits panel in the top bar has the full ledger, one line per movement.
