Which text tier for reading and storyboards

Quick answer: Read every script and storyboard every episode on the default tier first. Step up only per episode, when a storyboard has failed its checks twice or a long script came back with episodes missing: Evolving or Pro at the base rate, then Qwen3.8 Max for dense Chinese scripts. Qwen3.8 Flash is for cheap, fast drafts. The preference applies per task, so nothing forces a whole series onto one tier.

The default tier explains the three jobs a text tier does and what the site checks.

The table

Situation	Pick	Rate
Anything routine	Doubao Seed 2.1 Turbo (default)	50%
A storyboard failed twice	Doubao Seed Evolving (Recommended) or 2.1 Pro	100%
Dense Chinese script, large cast	Qwen3.8 Max	133%
Quick cheap draft to see an episode’s shape	Qwen3.8 Flash	10%

Rates are percentages of the base text rate; the pricing page turns them into credits.

What the site does before you need to switch

Every storyboard draft is checked for format and language; if it fails, the site asks for one more draft on the same tier before reporting a failure. Long scripts are read in two passes automatically. Upstream busy errors are retried once. So a single failure is not a reason to switch; two in a row on the same episode is.

The free first storyboard

The storyboard for episode 1 of your first project is free the first time it is generated — on the default text tier only. Generate it on any other tier and it is charged at that tier’s rate. While it is still unused, Settings shows a First one free badge on the default tier.

Chinese or English

The default and Pro tiers handle both. For dense Chinese, Qwen3.8 Max is the natural step up; for a hard English script, Evolving or Pro. Reading a script on a cheap tier and storyboarding the important episodes on a pricier one is the usual way to spend.

FAQ

Does the text tier affect the video?

Only through the storyboard it writes; the video tiers render what you approve.

Which tier is Recommended?

Doubao Seed Evolving.

Do I need to re-read the script when I switch?

No. A script is read once per project; switching affects new tasks, such as regenerating a storyboard.

Is the pricier tier always better?

No. On routine episodes the tiers produce comparable storyboards; the step up pays off on long, crowded episodes.

Is the free first storyboard available on every tier?

No. Only on the default text tier.

Start on the default, step up per episode

Read a script, storyboard the first episode on the default tier, and switch only where a storyboard keeps failing.
