SWEYET(etc.)

The developers describe how their game uses AI generated content like this:

Occasionally on real-life blink in-game textures may swap to pre-rendered AI variants of the textures for a moment. These textures were created with an outdated image generation model on local hardware to facilitate hallucinations. There was no new training of models for SWEYET(etc.), no wastage of water, etc. No generative AI runs on users machines, there is no runtime generation.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
