Unchanged from v1. This endpoint’s documented request and response schemas are identical in v1 and v2 — change the /v1 prefix to /v2. Schema equality is not a promise about behaviour, so keep your usual smoke tests.

Create a reference set (a curated collection of already-uploaded files) that can then be trained into a custom style/LoRA. Upload files first via the Files API, then pass their IDs here.
