Reddit Bets on AI to Revolutionize Online Moderation

Reddit Leverages AI to Revolutionize Online Moderation

Reddit is turning to AI to assist in moderating new subreddits—and eventually the entire site. The company is introducing automated moderation tools that rely on language models (LLMs) to help moderators manage their communities, and it is expanding access to these tools starting today ahead of a full launch expected later this year.

The company refers to this suite of tools as the "Rules Hub," which allows moderators to decide which rules should be applied automatically and what actions should be taken when a rule is triggered. The Rules Hub utilizes LLMs to assess “whether a post or comment aligns with the intent of a rule,” which “enables the Rules Hub to better handle nuances, natural language, and edge cases while preserving moderator control,” Reddit states in a blog post. Currently, many subreddits use tools from a feature called Automoderator (or Automod) to enforce rules, but Automod tools “rely on exact keyword and pattern matching.”

Reddit specifies that the Rules Hub has been tested “over the past few months” with “new and experienced moderators from over 700 communities, including members of Reddit's Mod Council Network.” This testing of the Rules Hub is now expanding to “all new communities created” and will be “widely available” at some point later in 2026.

The Rules Hub will be optional for new communities, according to spokesperson Rosa Kim. However, it appears that Reddit is considering phasing out Automod enforcement features in the future: in its message, Reddit states that “looking ahead, we believe the Rules Hub, combined with newer systems like Post & Comment Guidance and Safety Filters, could eventually replace many of the enforcement workflows that communities rely on Automod for.”

Automod has been “one of the most important moderation tools,” says Reddit CEO Steve Huffman in a message. “But it is also difficult to learn, hard to maintain, and heavily reliant on fragile keyword matching, regex, and legacy configurations that few people on a moderation team, if anyone, understand. We can do better.”

The updated moderation tools are just one of several significant announcements Reddit is making on Wednesday. The company is also planning major changes that will affect developers: it will require new third-party applications to use the development platform instead of the API.

“We envision a future where all good trusted automation on Reddit operates within an ecosystem that allows us to provide support and enforce our policies consistently,” Reddit states. “To achieve this, we will continue to support limited public access to the API, but we will gradually restrict new requests and require third-party applications to transition to and operate on Reddit's development platform.”

Reddit's public API was not designed for current scale, automated abuse, or commercial scraping, Huffman states. “We want useful bots, community tools, and good-faith developers to have a clear and well-supported way to build on Reddit. We do not want malicious actors to indiscriminately extract data from Reddit, resell its data, or use it irresponsibly.”

This change follows major modifications to Reddit's API in 2023, implemented to ensure that AI companies pay for Reddit's data, but which also sparked widespread discontent, partly because they forced many beloved Reddit applications to shut down. Currently, if a developer wants to create a Reddit mobile app, they must obtain permission from Reddit to receive public API exemptions, and this will continue to be the case, Kim states.

Reddit does not yet have a “fixed timeline” for requiring the development platform, but the company will provide “ample notice to the community” and a clear timeline, according to Kim. The upcoming change will affect “all API applications except those to which we explicitly grant exceptions,” Kim notes.

Reddit also announces today that it plans further changes to the old Reddit as part of its ongoing efforts to combat unauthorized scraping of its content. These efforts already include blocking Reddit results from search engines that do not pay, lawsuits against Anthropic and Perplexity, and blocking the Internet Archive to prevent AI companies from using it to extract data. In June, the company announced that users would need to be logged in if they wished to use the old Reddit interface.

Reddit does not specify what changes will be made to the old Reddit, but Kim indicates that the company is “exploring different options” and notes that “in the short term, we will limit access to logged-in users and migrate critical bots and moderation workflows.”

“In order to protect our platform, our company, and our users, we will need to do something” with the old Reddit, Huffman states. “In reality, a lot of things. We have options: we can limit access, migrate important uses, or rebuild it on a modern technology architecture, and I think we will likely do all of that.”

Huffman also acknowledges that users may be wary of significant changes. “We know that announcements regarding APIs and legacy products come with some baggage,” he says. “‘Trust us’ is not enough. If we ask you to transition to something new, it must be at least as good or better in practice, not just in theory.” He asserts that Reddit will not “remove major features until there is a credible replacement,” will work with moderators, developers, and affected communities, and will “share important milestones along the way before any of these changes are implemented.”
