Steam

Do I have to disclose AI coding (Copilot, Cursor, vibe coding) on Steam?
Usually not. Valve's Content Survey says efficiency gains from AI-powered tools are 'not the focus' of the AI section, which covers content that ships with your game and is consumed by players. Game Developer's report on the updated form…
My game was rejected by Steam over the AI disclosure. What do I do?
Correct the Content Survey so it matches what is actually in your build and on your store page, explain the change in your reply, and resubmit. Valve says reviewers compare your answers with the build and the store page, and that after…
What should I write in Steam's AI disclosure?
Be specific. Valve says the section requires you to describe your AI use 'in detail'. Our suggestion (not Valve's wording): say which content is AI-generated (for example: item icons, background music, NPC barks, store capsule), which…
Does Steam's AI disclosure cover store page art, capsules and trailers?
Yes. Game Developer reported (Jan 16, 2026) that Valve's updated form counts the game itself and associated material like marketing assets or the store page. The public Steamworks page still describes only content that ships with the game…
Does Steam allow AI-generated assets at all?
Yes. Steam accepts games with AI-generated art, audio and text if you disclose it in the Content Survey. Valve reviews AI output the same way as any other content, shows much of your disclosure on the store page, and asks for guardrails if…
Does Steam show players that my game uses AI? (AI tag vs disclosure)
Yes. Valve says it includes much of your AI disclosure on the game's store page.
Can I ship live / runtime generative AI (LLM NPCs, AI images) on Steam?
Required (pre-generated and live AI). Disclose AI content that ships and is consumed by players (pre-generated), and describe guardrails for live-generated AI. Efficiency tools used during development are not the focus.
Someone recreated my game with AI and threatens to publish it on Steam. What can I do?
If you hold the copyright, Valve's Content Survey FAQ points you to its DMCA notice form (and a separate form for trademark complaints). Whether an AI re-creation infringes depends on what was copied (code, art, characters, names), so…

itch.io

Does using AI to debug or fix code count for itch.io's AI disclosure?
If AI-written or AI-edited code ships in the game, tick Code in the disclosure: itch.io's form lists Code as one of the kinds of generative AI it asks about, and its guidelines ask you to tag materials produced by generative AI. If AI only…
Is AI disclosure mandatory on itch.io for games and assets?
For asset pages, yes: itch.io says the field is now required for all asset creators. For games, itch.io asks you to tag accurately if the project contains generative-AI material.

Other stores

Does the Epic Games Store require AI disclosure?
Not required. No AI disclosure requirement in Epic's published distribution requirements (it does require disclosure of paid promotional content). Epic's store VP: 'We do not police how developers make their games.'
Can I sell AI-made assets on the Godot Asset Store?
Required for assets you sell/publish. AI-generated assets and code are allowed if you disclose what is AI-generated and how AI was used, including AI output you edited or embedded in human-made work.

Open-weight models

Can I use FLUX [dev] outputs in a commercial game?
Unclear (unverified), so play safe. The FLUX [dev] Non-Commercial License (updated Nov 25, 2025) lets you use outputs commercially 'except as expressly prohibited', but only allows using the model for Non-Commercial Purposes, and it says…
Is FLUX schnell OK for commercial use?
Yes. Black Forest Labs' model card says it's released under Apache 2.0 and can be used for personal, scientific and commercial purposes.
Can I use Stable Diffusion (SDXL, SD 3.5) for a commercial game? What's the $1M rule?
Under US $1M annual revenue (you and your affiliates), the Stability AI Community License is free, but you must register with Stability AI for commercial use. Above $1M the licence ends and you need an Enterprise licence.
Can a LoRA or fine-tune stop me selling images made with it?
They can only add restrictions. SDXL's licence says derivative models must keep at least its use restrictions, and Stability's Community License treats LoRAs as Derivative Works under the same terms. Check each LoRA's model card.
Is Qwen-Image 2.1 allowed for commercial use?
The original Qwen-Image is Apache 2.0, so yes. Qwen-Image-2.1 is under the Qwen Research License (released Sep 20, 2026): no commercial use without a separate commercial licence.

Can I use Suno songs in my game after the 2026 terms change (download allowance)?

Copyright

Who owns an AI-assisted game? Is AI art public domain?
Mostly yes, for the parts people made. In the US, copyright doesn't cover purely AI-generated material, but your code, writing, level design, creative edits, and the selection and arrangement of AI assets can be protected. Japan and South…
