Dialog Translation, Image Translation, and Selection Translation share a common free quota, which resets at 0:00 UTC daily
When using Dialog Translation, Image Translation, or Selection Translation beyond the free quota, the minimum billing unit is 350 characters per message, per image, or per selected content. For each message, image, or selection, 1 Shell is consumed for every 350 characters. Any portion under 350 characters is still charged as 350 characters. If the source text of a single message, image, or selection contains fewer than 350 characters, 1 Shell will be deducted. (Character count is based on the original text to be translated)
Once simultaneous interpretation voice recognition is activated, billing continues even if no speech is detected. Please remember to pause interpretation when not speaking.

Video translation function will deduct shells after starting the translation task. If the translation fails, the shells will be refunded.
