# Create Model Instances Bulk

`POST /v1/model-instances/bulk`

Create many model instances in a single request.

Partial-success semantics: each item is created independently and per-item
failures are returned in `failed` rather than aborting the whole batch.
Use this from UIs that let users select N models from a discovered list to
avoid N HTTP round-trips.
