Steam AI Policy: What Every Game Developer Needs to Know

By the first half of 2025, 8,000 games had disclosed AI use on Steam, compared to roughly 1,000 in all of 2024. One in five new releases now carries an AI disclosure.

Steam’s AI disclosure policy became real compliance infrastructure fast.

News coverage focuses on the controversy. What developers actually need are the mechanics: the exact disclosure steps in Steamworks, what seems to trigger a disclosure requirement, what doesn’t, and where your legal liability sits.

Here’s what every developer should know before they submit to Steam.

Quick Facts: Steam AI Policy

• Steam’s AI disclosure policy launched in January 2024 and was recently tweaked on January 17, 2026
• The Steamworks Content Survey has three mandatory sections: General Content, Mature Content, and Generative AI Content
• Two types of AI content require separate disclosures: pre-generated (created during development) and live-generated (created during gameplay)
• AI disclosures appear publicly on the Steam store page under “About This Game”
• Valve added a Steam overlay button for players to report illegal AI-generated content
• Developer tools like GitHub Copilot are explicitly exempt under the January 2026 rewrite
• Live AI-generated Adult Only Sexual Content is an absolute prohibition with no exception
• 1 in 5 new Steam releases features an AI disclosure as of early 2025 (a number which is sure to rise over time)

Key Definitions

Pre-Generated AI Content: Valve’s exact definition is “any kind of content (art/code/sound/etc) created with the help of AI tools during development.” This covers AI-generated assets baked into the game before it ships, as opposed to content produced in real time.

Live-Generated AI Content: Valve defines this as “any kind of content created with the help of AI tools while the game is running.” Examples include AI-generated dialogue, procedural environments, or NPC behavior driven by a live model during a play session.

Generative AI: AI systems that produce new content outputs, such as images, text, audio, or code, in response to inputs. This is distinct from AI used for logic, pathfinding, or optimization, which has been standard in game development for decades.

Training Data Provenance: The chain of origin for the data used to train an AI model. Valve has used questionable training data provenance as an independent ground for rejection, separate from whether the developer disclosed AI use.

Steam Distribution Agreement (SDA): The contract between Valve and every developer who ships on Steam. When you check disclosure boxes in Steamworks, you are making attestations under this agreement. Non-disclosure can constitute breach of contract.

How the Steamworks Disclosure Process Actually Works

The Steamworks Content Survey, which every developer publishing a game on Steam fills out, gates every new submission. The third mandatory section is Generative AI Content.

Understanding what each field commits you to legally is the prerequisite to filling it out correctly.

The threshold question: “Does this game use generative artificial intelligence to generate content for the game, either pre-rendered or live-generated?”

Answering yes opens two sub-disclosures (discussed below). Both are mandatory if applicable.

Pre-Generated AI Disclosure

This covers, in Valve’s words, “any kind of content (art/code/sound/etc) created with the help of AI tools during development.” You get a free-text explanation box.

Under the Steam Distribution Agreement, you are affirming that the game contains no illegal or infringing content and that the product is consistent with your marketing materials.

Based on information we’ve seen, and the general need for disclosure, you should fill it out specifically: name the tools, describe the content categories, explain your process.

Vague answers invite follow-up and can undermine your legal position if a dispute arises later.

Live-Generated AI Disclosure

This covers content produced by AI while the game is running.

You must describe the guardrails you have in place. Valve’s exact language: developers must describe “what kind of guardrails you’re putting on your AI to ensure it’s not generating illegal content.”

One hard line: Adult Only Sexual Content generated by live AI is an absolute prohibition. There is no path to approval for this combination.

On live AI economics: Valve expects developers to manage AI service costs through pricing, microtransactions, subscriptions, or DLC.

If your live AI model has usage costs that scale with players, budget for that before launch.

Where Disclosures Appear

The AI disclosure is visible to all prospective players on the Steam store page, under “About This Game.” Write it as a public-facing document, because it is one.

Accurate and specific disclosures protect you; vague ones create a paper trail of ambiguity.

What Requires Disclosure and What Does Not

The January 17, 2026 policy rewrite clarified a distinction that had caused serious developer confusion: AI tools used in development versus AI-generated content that actually ships to players. The rewrite refocused the policy on player-facing content only.

What Is Exempt

According to the update (as of January 2026), no disclosure is needed for:

• GitHub Copilot and other code-assist tools
• AI used for concept art ideation where the output is not shipped
• AI-powered developer software and efficiency tools (Valve’s exact language: “Efficiency gains through the use of AI powered tools is not the focus of this section.”)
• AI used for porting or optimization work
• Tools like Adobe Substance 3D with Firefly, unless the AI-generated output appears in the shipped game

What Requires Disclosure

Disclosure is required for:

• AI-generated art, audio, or narrative that appears in the game
• AI localization of shipped text or dialogue
• Marketing assets and Steam page content generated by AI
• Live AI content generated during gameplay
• Steam Community assets created with generative AI

The Gray Zone

No bright-line rule exists for heavily human-edited AI content. Valve has not published a percentage threshold or a test for when editing is sufficient to remove the disclosure obligation.

Because of this, it’s important to document your editorial process regardless. Keep the original AI output, your revision history, and the final version.

If substantial AI-generated material remains recognizable in the final product, disclose.

The tool you used is not the question. What the player sees is the question.

Legal Liability: Copyright, Platform Agreements, and What the Attestation Shifts to You

When you check the disclosure boxes in Steamworks, you are making a legal attestation. Valve’s attestation mechanism shifts copyright liability for AI-generated content entirely onto the developer. Valve absorbs none of it.

The Copyright Protection Gap

In Allen v. U.S. Copyright Office (2024), a purely AI-generated image was denied copyright registration. The US Copyright Office’s March 2025 guidance confirmed the standard: works must “ultimately be the product of human authorship” to qualify for protection.

I covered the full implications of that guidance in my breakdown of AI copyright for game developers.

The practical implication is direct. If your game ships AI-generated art with no substantial human creative input, you may have no IP protection over those assets. Competitors can legally copy them.

Training Data Provenance Risk

Some developer rejections were framed around training data rights. In SAG-AFTRA v. Llama Productions (2025), an Epic Games subsidiary was sued for AI voice replication without bargaining.

Developers using third-party AI tools do not inherit the tool’s indemnification. They inherit the exposure from the owners of the underlying training data. As of this writing, many of these court cases governing liability for training data infringement are either still ongoing or have settled out of court.

So there’s no clear answer yet on the infringement question for AI-produced materials.

Breach of Platform Agreement

Non-disclosure may constitute breach of the Steam Distribution Agreement, with consequences that extend beyond game removal. This is a contract claim separate from any copyright dispute.

The form is a legal document, so you should definitely treat it like one.

Is it a huge risk that Valve would sue a developer over this? Probably not, but it’s not really something you want to find out.

Building a Compliance Posture That Holds Up

Compliance with Steam’s AI policy is not a single form submission. It is a development-lifecycle practice.

Developers who get into trouble are the ones who make the disclosure decision at launch, not during production.

Audit AI Use Before You Ship

Map every asset category: art, audio, dialogue, localization, marketing materials, Steam page content. Tag which involved AI tools and whether those outputs appear in the shipped product.

This ongoing audit is the foundation of your disclosure and your primary defense if Valve or a rights holder raises a challenge.

Document the Human Editorial Layer

For any AI-generated content you are disclosing, or believe may be exempt due to heavy editing, document the editing process contemporaneously. Source files, revision history, original AI outputs, and final versions all matter.

This is your evidence that human authorship is present, which is relevant to both copyright registration and Valve review.

Vet Your AI Tools’ Terms

Does the AI tool vendor you use have a license that permits commercial use in a shipped product? Check before you build a pipeline on a tool.

Previous cases have shown that Valve can reject on training data provenance grounds regardless of how much you edited the output. The vendor’s terms do not become your protection automatically, so be cautious about any integration of AI tools into your process (image and story generation seems particularly fraught, as those are the ones with court cases currently in motion.

Disclose Early and Disclose Specifically

Name the tools, describe the content category, and explain the guardrails for any live-generated content.

Denial may be punished more harshly than initial disclosure. A specific, accurate disclosure is typically going to be a far smaller problem than a vague or missing one, though if it’s clearly not allowed by Valve, you’re going to face an uphill battle either way.

The main problem we see is that your ability to publish on Steam is ultimately up to Valve, the the reasons aren’t always completely transparent or even logical.

Watch the Policy

Steam’s AI rules underwent a relatively major focus shift in January 2026 after the initial 2024 launch. Build a review trigger into your release process for any title still in development, and revisit your disclosures if the policy changes after your initial submission.

This is not a set-and-forget compliance step. You need to keep on top of things in order to plan for and stay in compliance.

Related Questions About Steam’s AI Policy

Does Epic Games Store have the same AI disclosure requirements as Steam? No. Epic Games Store has no AI disclosure requirements as of this writing. Epic CEO Tim Sweeney has publicly criticized Steam’s policy, arguing it facilitates “cancel campaigns and review bombing” against small developers. This is a meaningful competitive distinction for developers evaluating platform strategy.

Can Valve reject a game solely because of AI use, even with full disclosure? Yes. Previous cases have demonstrated that Valve can and does reject games on training data provenance grounds even when the developer discloses AI use and edits the AI-generated content. Disclosure is necessary but not sufficient.

Does the Steam AI policy apply to DLC and updates, or just the base game? Valve’s policy applies to content on Steam, including updates and DLC that add new AI-generated assets. If you add AI-generated content post-launch, review whether your existing disclosure covers it or whether an update is needed.

What does “guardrails” mean in practice for live-generated AI content? Valve does not publish a technical specification, as far as I can see. In practice, guardrails means content filtering, prompt restrictions, or moderation systems that prevent the live AI from generating illegal content during a play session. Best practice would be to describe whatever system you have in place specifically in the disclosure text box.

FAQ

Do I need to disclose AI use if I only used it for internal tools, not the shipped game?

No. The January 2026 rewrite carved out dev tools explicitly. GitHub Copilot, AI-assisted debugging, and concept art generators used for ideation but not shipped are all exempt. The line Valve draws is whether the AI-generated content is in the product the player experiences.

I used AI to generate a draft and then edited it heavily. Do I need to disclose?

It depends on whether recognizable AI-generated content appears in the shipped game. There is no bright-line percentage. Document your editing process and, when in doubt, disclose. Keep the original AI output, your revision history, and the final version as evidence of human creative input. From a copyright standpoint, that documentation is your protection.

Does the AI disclosure requirement cover my Steam page and marketing assets?

Yes. Valve’s policy explicitly covers Steam page content, marketing assets, and Steam Community assets, not just in-game content. AI-generated store page artwork or promotional copy requires disclosure.

What if I’m falsely accused of using AI when I didn’t?

Maintain documentation of your asset creation process: source files, version history, and original drafts. There is currently no published formal appeal path for false-positive AI accusations on Steam that I know of, which makes contemporaneous documentation your only practical defense.
