r/OpenAI

r/OpenAI is the 3rd largest of the 12 communities we track in AI & Data Science, with 2.8M members. That is about 24% the size of the niche's biggest community, r/ChatGPT. Across Nichory's full directory of 363 communities it ranks 110th by member count.

At around 11 years old it is reasonably mature: the culture and rules are established, while there is still room for new contributors to become recognisable names fairly quickly.

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.

This community allows promotion only under conditions — typically a designated thread, a participation ratio, or moderator approval. Read the rules first, then either use the thread they provide or write a post that teaches something, with your product as context rather than the headline.
