First measured result
CogVideoX-3 needed 29% more budget than clean per-second math
The 2026-09-17 run's $0.20 per-video baseline works out to $0.0400 per requested second for this five-second setup. One billed request was not retrievable and four sampled seconds failed the usability rule, raising the observed cost to $0.0516 per accepted second.

Every provider faces the same buyer-focused accounting
01 · Repeat
Multiple attempts
We repeat each prompt and modality so a single lucky clip cannot decide the verdict.
02 · Preserve
Billing + outputs
Request state, task IDs, latency, output hashes, failures, and observed billing are retained.
03 · Grade
Usable footage
Prompt adherence, temporal consistency, text accuracy, and severe artifacts are scored separately.
04 · Normalize
Accepted-output cost
We report cost per accepted clip and usable second, including billed failures and rejected footage.
Next: larger Z.ai benchmark wave
More generation stress tests plus video-understanding checks
The next runs stay on earned Z.ai bonus credit: a larger CogVideoX-3 prompt set for motion, camera control, exact text, and repeatability, followed by timestamped video-understanding tasks. Results will appear here only after billing evidence, outputs, grading, maintained official price sources, and independent verification are complete.
