Gold gives you strong priority to keep your client work moving across the shared queue. Platinum (Partner) goes further: it reserves a portion of execution capacity for you, so your critical work is handled first regardless of overall demand. Because this is real, finite bandwidth—not just higher priority—Platinum is limited to 3 partners to guarantee delivery.

Work is scheduled into quarterly releases. Priority determines what gets in next. 

Use upstream priority to reduce delivery delays and unblock client work faster.
