DAU over free quota will be charged at 149.99 USD/10,000 DAU per month, with counts less than 10,000 billed as 10,000. The DAU fee is pay-as-you-go on a monthly basis. Fees incurred within a month will be deducted on the third day of the next month.
If the DAU of each day within a month is lower than 10,000, no DAU fees will be incurred for that month. If for any day within a month, the DAU is higher than 10,000, you will be charged based on the highest DAU value in that month.

If you created 3 audio-video groups and then deleted 3, you can still create 50. The number of audio-video groups you can create is a net value. Deleted groups do not count against the quota.

The number of groups that you can create is unrestricted, but if you create more than 100,000 groups, you will need to pay certain resource fees. The total group count is a net value. If you delete a group, it is not included in the total group count.
The fees are as follows: 149.99 USD/month per 100,000 groups (counts less than 100,000 will be billed as 100,000) if the total group count exceeds 100,000. For more information, see Pricing.
