http://Itch.io just deleted a couple terabytes of AI slop, as nearly half of Steam's new games disclose AI. Here's what you need to know.

http://itch.io posted "Just deleted a couple terabytes of ai slop" on Nov 3, 2026. The post passed 576.9K views, with about 52K likes. Two days earlier, http://itch.io said the number of game pages created per day had doubled in the past 2 months.

The post landed the same day a survey of about 63,600 Steam games was shared widely. It found 49.9% of new Steam games released in October 2026 disclosed using AI-generated content. That is up from 1.7% in January 2024. Only about 3% of games use AI to generate content during play.

The yearly share has climbed fast. In 2024, 13.2% of games disclosed AI content. In 2025 it was 24%. So far in 2026 it is 40.1%.

Steam's rules matter here. Valve requires AI disclosure, and it now focuses on player-facing content like in-game art and sound. A July 15, 2026 update extended labeling to third-party AI integrations. Disclosure is self-reported, so some commenters say real use is higher.

Readers note the percentage may overstate how many developers use AI. A small number of people upload dozens of AI games a week, which inflates the count. One analysis found these games are about 40% of 2026 releases but get only 12% of reviews. Others say AI-tagged games rarely get more than a handful of reviews. Some critics also said http://itch.io's own platform hosts stolen and cloned games.

Key numbers:
- 49.9% of new Steam games in October 2026 disclosed AI content
- 1.7% in January 2024
- 13.2% across 2024, 24% across 2025, 40.1% so far in 2026
- About 63,600 Steam games surveyed
- About 3% use AI generation during play
- Roughly 40% of 2026 releases, only 12% of reviews
- http://itch.io daily game pages doubled in 2 months

So AI disclosure went from rare to nearly half of Steam's monthly releases in under three years.
