Reddit introduces AI moderator with new Rules Hub and plans major developer changes

Reddit is enlisting AI to help moderate new subreddits and eventually the rest of the site. The company is introducing automated moderation tools called Rules Hub, which rely on large language models (LLMs) to evaluate whether a post or comment matches the intent of a rule, allowing for better handling of nuance and natural language while preserving moderator control. Currently many subreddits use Automoderator (Automod), which depends on exact keyword and pattern matching. Rules Hub has been tested with moderators from over 700 communities and is now expanding to all newly created communities, with a full launch later in 2026. Reddit plans to eventually retire Automod's enforcement features in favor of Rules Hub and other systems like Post & Comment Guidance and Safety Filters. The company is also making major changes for developers: it will require new third-party apps to use the developer platform instead of the API, gradually restricting new API requests. This shift follows Reddit's 2023 API changes that forced many beloved apps to shut down. Reddit is also planning more changes to old Reddit as part of its efforts to fight unauthorized scraping, including limiting access to logged-in users and migrating critical bots and moderator workflows. A spokesperson noted the company is exploring different options and will provide ample notice before requiring the developer platform.
