Quotas and limits in Vision OCR

  • Quotas are organizational constraints that can be changed by support on request.
  • Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.

If you need more resources, contact support and tell us which quotas you need to increase, for which models, and by how much.
