Quotas

Each organization has a cap on the number of managed deployments running at the same time:

PlanConcurrent managed deployments
Free0 — managed deployments require a paid plan
Pay-as-you-go3
Enterprise10

Creating or starting a deployment beyond the cap fails with a 403 error. Stop or delete a deployment to free a slot. Caps can be raised per organization — contact Mistral support.

Mistral Cloud also picks the instance size for you. Every managed worker gets the same size, and per-deployment CPU and memory metrics are not exposed yet.
