r/MachineLearning

r/MachineLearning is the 2nd largest of the 12 communities we track in AI & Data Science, with 3.1M members. That is about 26% the size of the niche's biggest community, r/ChatGPT. Across Nichory's full directory of 363 communities it ranks 100th by member count.

At around 17 years old it is a long-established community. Older subreddits usually have settled rules, active moderation and high trust — but also years of archived posts, so a question that has been asked before will be sent to the search bar. Bring a specific angle.

Its Nichory signal score is 10/10 — our blend of audience size and how fast the community has grown per year. Scores this high mean an active audience that is worth writing for properly.

Our rules analysis flags this community as prohibiting self-promotion. Posting a link to your own product here is the fastest way to get removed or banned. Treat it as a place to build a reputation by answering questions well — your profile does the selling for you.
