Steam's AI disclosure: do trailer and capsule art made with AI count?
Steam's content survey asks about pre-generated and live-generated AI. Which one covers a trailer or capsule art made with a Sume model, and what must match.
Steam asks you to describe AI use in its content survey, and the question has two halves. According to the Steamworks content survey page, read on 2026-10-05, the AI Generated Content section covers pre-generated content, which ships with the game or is consumed by players, and live-generated content, for which you describe the guardrails. Your answers are shown on the store page.
That wording matters for a trailer. Steam's page frames the survey around content players consume in the game. It describes efficiency tools as not the focus. I did not find a line that says a store-page trailer or capsule image made with AI must be declared in the same section, so I will not state one.
Where marketing material fits
The same page says marketing materials must be consistent with the game. That is the rule I would build around. A trailer made with a generated model, such as one run through the Sume video API, should show what the game really looks like. A generated cinematic of a world your game does not have is a consistency problem whether or not you disclose AI.
Sorting your assets
| Asset | Likely bucket | Why |
|---|---|---|
| AI texture or voice line shipped in the build | Pre-generated | It ships with the game and players consume it |
| Character that talks to players through a model at runtime | Live-generated | Guardrails must be described |
| Trailer cut from real gameplay, captions generated | Not the focus | Page says efficiency tools are not the focus |
| Trailer with generated scenes the game lacks | Consistency risk | Marketing must match the game |
What to do with a Sume trailer
Use Sume clips as b-roll or atmosphere only if the final trailer still shows real gameplay, and keep the generation record. For each clip, keep the job id and model. Sume job metadata is stored on the job and is not sent to the provider, so you can tag a clip with the build version it illustrates.
If a generated scene is in the shipped game, answer the pre-generated question honestly. If you are unsure which bucket applies, the Steamworks survey is the authority; this post only maps what the page says on 2026-10-05, and it may change.
Sume's docs describe a metadata field on video, image and music jobs that Sume stores on the job and does not send to the provider. I found nothing in the docs about Sume adding, keeping or removing C2PA credentials, watermarks or platform labels, so treat that as undocumented and check the delivered file.
