Capabilities describe the Manyframe connector. Your studio shows the currently enabled route, supported settings and maximum charge.
Choose the composition before the attempt.
A vertical social scene and a landscape website scene place the subject differently. Decide the destination, choose a supported size and make the subject's position clear in the brief or starting image.
Keep this Fast Preview identifier distinct from the other 3.1 route. Model names alone do not establish a performance or price ranking. Compare complete outputs using the same inputs, then check the quote for the version you actually choose.

Can I paste any image URL as a reference?
The Google bindings accept encoded data or a supplied image file. The Vertex image path uses JPEG or PNG; arbitrary external URL input is not established by this connector.
Does preview access apply to every account?
No. Enabled routes, usable settings and provider entitlement depend on the account. Check the available model in Studio.
