Reddit is rolling out AI-powered moderation tools, part of a broader set of platform changes affecting developers and old Reddit. The new system, called "Rules Hub," uses large language models to help moderators enforce community rules by understanding context and intent rather than relying solely on rigid keyword matching, marking a shift away from the long-standing Automoderator tool.

Rules Hub has been trialled for several months across more than 700 communities and is now expanding to all newly created subreddits, with a wider rollout planned later in 2026; it will remain optional for now, though Reddit suggests it could eventually replace much of Automod's enforcement role. Alongside this, Reddit is requiring new third-party apps to migrate from its public API to its Developer Platform, continuing a shift that began with 2023's controversial API changes, and is also planning further restrictions on old Reddit to curb unauthorised scraping.
