Qwen3.8 Flash

Quick answer: Qwen3.8 Flash is a low-cost text tier at 10% of the base rate, and quick to answer. It is the tier for a quick read of a short script or a draft storyboard to see an episode’s shape. Dense episodes are where it is most likely to miss the storyboard format; when that happens, the site’s retry and then a higher tier are the path.

Qwen3.8 Max is the full-size sibling for hard scripts.

Where you pick it

Settings → Model Preferences → Text Model. The choice applies to the three text jobs that cost credits — reading a script, writing a script with AI, and generating an episode’s storyboard — from the next task on. Translations of what you see on screen and the small helper calls do not follow it. Nothing already generated is redone by switching.

What it is good for

Speed and cost. Reading a short script to see its cast and episodes in seconds; a first storyboard of an episode to check the shot count and pacing before you commit a pricier tier; AI-written drafts you expect to rewrite. The site itself uses this tier for the quick style suggestion it makes when you create a project.

Where it falls short

A long or crowded episode is where a fast, low-cost tier is most likely to miss the strict storyboard format — a shot without its duration, a character named who is not in frame. The site checks every draft and asks for one more before reporting a failure; on this tier that second draft is needed more often. Treat a failure as a signal to step up for that episode.

What it costs

On this tier, reading a script costs 1 credit per thousand characters (a thousand equivalent characters for alphabet-based scripts, see the pricing page), a storyboard costs 1 credit per hundred characters of the episode’s share of the script, and AI writing costs 1 credit per thousand characters written. That is 10% of the base rate. Most failed tasks are refunded automatically; a few kinds of failure hold the credits until support checks the task.

The default tier is at 50%.

Common errors

What you may meet on this tier:

What you seeUsual causeWhat to do
A long script or a dense episode failsThe reply ran past what one call can return; the site already ran it once moreThe credits stay held until support checks the task. Trim the script or split it before running again
Storyboard generation failedNeither of two drafts came back as a usable storyboardNothing was saved or charged; the credits stay held until support returns them. Regenerate, or switch tier
“The generation service hit a temporary problem. You weren’t charged — feel free to try again.”The service was saturated; the site already tried again onceTry again in a few minutes
The storyboard came back in the wrong languageThe tier ignored the language settingThe site redoes it once automatically; if it still arrives wrong, regenerate or switch tier

When to switch tier

To the default for anything you will keep. To Qwen3.8 Max for hard Chinese scripts. A script is read once, on the tier you had at the time; for a better read of the same script, switch tier and start a new project with it.

FAQ

Why is its rate so low?

Tier rates follow what each tier costs to run, and this one costs little.

Can I use it for a whole series?

You can. Expect more storyboard retries on long or crowded episodes; switch those episodes up.

Why might a storyboard fail the format check here?

The format is strict, and a dense episode asks a lot of a fast tier. The site retries once; if it still fails, step that episode up.

Does the site use it anywhere by itself?

For the style suggestion when you create a project, where speed matters and the stakes are low.

Is a Flash storyboard usable for video?

If it passed the checks, yes. The video tiers read whatever storyboard you approve.

See an episode’s shape for almost nothing

Draft a storyboard on Flash, check the pacing, then regenerate the keepers on a higher tier.
