Video caption pack
Generate timed captions for Bilibili videos without configuring an API key. Actual video duration is deducted; failed jobs are free.
One-time purchase, valid for 365 days after redemption, and shareable across videos.
Token packs
Subtitle translation, smart segmentation, and video summaries deduct the actual input and output tokens reported by the model. Failed requests, idempotent retries, and shared-result hits are free.
Light pack
3,000,000 tokens
For occasional top-ups across a few long videos or subtitle translation batches.
Study pack
8,000,000 tokens
For course-style learning with translation, summaries, and smart segmentation in one quota.
Heavy pack
20,000,000 tokens
For intensive long-video processing, course series, or high-frequency shared use.
After purchase, copy the code delivered by LDXP and redeem it while signed in to Lumi. Pro tokens reset monthly; token pack balances last until used.
