Nearly half of all games released on Steam in October 2026 disclosed the use of generative AI, according to a community analysis covering approximately 63,600 titles. The reported disclosure rate reached 49.9%, up from 26.4% in October 2025, highlighting a substantial increase in developers acknowledging AI-generated content in their games and promotional materials.
The findings were published on November 2 by Steam community researcher ploz, who operates the unofficial PC gaming database PCGame.com. The analysis examined games released since Valve introduced its generative AI disclosure requirements in January 2024, using disclosure information stored in Steam’s own data.
The research indicates that AI disclosures have increased steadily over the past three years. When Valve first introduced the requirement in January 2024, just 1.7% of newly released games disclosed generative AI use. Across 2024, the figure averaged 13.2%, rising to 24% in 2025 and reaching 40.1% for the first ten months of 2026.
October’s 49.9% figure represents the highest monthly disclosure rate highlighted in the research, although the findings are based on developer-reported information rather than independent verification of every game’s development process.
The analysis also reveals substantial differences in how developers are using generative AI. Among games with an AI disclosure, artwork was the most frequently identified application, appearing in 63% of disclosures. Text generation and translation followed at 30%, while 26% mentioned AI-generated store page content or marketing materials.
Other reported uses included music at 21%, coding at 16%, and voice generation at 7%. Only 3% of games with AI disclosures reported generating content dynamically during gameplay, suggesting that most disclosed applications involve material prepared before release rather than systems that continuously generate new content while players interact with a game.
Another 8% of disclosing games indicated that their AI use was limited to their Steam store pages.
These categories are not mutually exclusive, meaning a single game can appear in multiple groups if its developer reports using AI for several purposes.
The findings are particularly relevant to how PC gamers discover new releases on Steam. The platform hosts a large range of independently developed games alongside major commercial releases, with events such as the October 2026 Steam Next Fest highlighting the breadth of upcoming PC titles.
However, the research indicates that AI disclosures are considerably more common among smaller games than among titles attracting larger numbers of user reviews.
Among games released in 2026 with fewer than 10 Steam reviews, approximately 47% disclosed generative AI use. That figure dropped to 14% among games with at least 1,000 reviews.
The researcher also compared developers based on their release frequency. Games from developers who published at least 10 titles during 2026 had an AI disclosure rate of 68%, compared with 37% for developers who released only one game.
These differences suggest an association between higher release frequency and AI disclosure, but the data does not establish whether generative AI directly enabled developers to publish games more quickly. Similarly, review counts do not provide a definitive measure of production budgets, development team sizes, or commercial success.
The analysis also examined player reception. Among games with at least 50 Steam reviews, titles disclosing generative AI averaged 77% positive user reviews, compared with 83% for games without an AI disclosure.
That six-percentage-point difference does not demonstrate that generative AI causes lower review scores. The figures do not isolate other factors affecting player reception, including game quality, pricing, genre, developer reputation, or differences between the types of games in each group.
Steam user reviews remain one way to evaluate player reception, with individual releases sometimes experiencing significant changes in approval ratings. For example, Modern Warfare 4's Steam review performance illustrates how approval percentages can become a prominent indicator of a game’s reception.
An important limitation of the new research is that Steam’s AI disclosures depend on information submitted by developers. Games that use generative AI without reporting it are not counted among disclosed titles.
Valve’s Steamworks documentation also distinguishes between AI-generated content included in a finished product and tools used exclusively to improve development efficiency. The disclosure requirements focus on material players encounter, such as artwork, audio, narrative content, and localization, rather than every instance of AI-assisted development work.
The researcher noted that disclosure rules were narrowed in January 2026 to focus on content players can see or hear. This means the historical figures are not necessarily directly comparable measures of all AI use during game development, particularly when developers use AI tools behind the scenes.
Valve distinguishes between pre-generated content created during development and live-generated content produced while a game is running. Developers using live generation must additionally describe the safeguards intended to prevent the generation of illegal content.
Consequently, the October figure should not be interpreted as evidence that nearly half of new Steam games are primarily AI-generated. A title that uses AI-assisted translation for part of its dialogue may carry a disclosure alongside another game that relies extensively on generated artwork, music, or narrative material.
For players interested in identifying these differences, Steam provides an AI Generated Content Disclosure section on individual store pages. However, the platform does not currently offer a built-in storefront filter that separates games based on their disclosed AI use.
The latest findings establish that generative AI disclosure has become increasingly common among new Steam releases, while also showing that its reported applications vary considerably between games. The distinction between disclosure and actual AI usage remains essential when interpreting the trend.
