Runway/gen4_aleph API

Runway Gen-4 Aleph(model id /gen4_aleph) is Runway’s in-context, video-to-video model that extends the Gen-4 family with powerful video editing, shot continuation and view-synthesis capabilities. In plain terms: Aleph can take an input clip and perform complex edits — add/remove/replace objects, relight, restyle, generate novel camera angles, and even generate the “next shot” in a sequence — driven by text prompts and optional reference images. This release is presented as a major step toward coherent, multi-shot video generation and in-context editing.
