Azure Document Intelligence Rate Limits

Azure AI Document Intelligence enforces tier-specific transactions per second (TPS) ceilings. F0 (Free) is capped at 1 transaction per second; S0 (Standard) defaults to 15 TPS and can be raised on request via Azure support. Per-document size caps and per-call page caps depend on model and API version.
