# Regenerating Content (/docs/social/regeneration)



Regeneration is driven by the content-container **change requests** API
(`POST /projects/{projectId}/content-containers/{id}/change-requests`).
Two modes are supported:

## Full regeneration [#full-regeneration]

`mode: "full"` — discards the existing output and generates from
scratch. Optional `changes` let you steer the new generation, for
example switching `media.type` from `video` to `slideshow`, or picking
a new overlay style.

## Partial regeneration [#partial-regeneration]

`mode: "partial"` — edits one or more elements while keeping the rest:

* **Caption only** — pass `changes.caption`.
* **Overlay text / style / position** — pass the relevant overlay
  fields.
* **Swap media** — pass `changes.media = true` (regen new media) or a
  full `MediaSchema` object to change type / style / format.
* **Slideshow slides** — for slideshow containers, pass per-slide
  `slideOps` with `keep` / `overlay` / `regen` / `replace`.

You must include at least one change. Caption-only edits can't be
combined with overlay or slide changes.

## Clone from a platform post [#clone-from-a-platform-post]

The inspiration path uses the `cloneFromPlatformPost` workflow — pick a
`platform_post` and Layers produces a brand-aligned variant. See
[Inspiration](/docs/social/inspiration).

## Cost [#cost]

Every change request is priced in credits; partial edits are typically
cheaper than a full regeneration because locked elements are reused.

## Reference [#reference]

* The full change-request schema — supported media types, overlay
  positions, slide operations — is described on the relevant API
  reference pages.
