r/StableDiffusion rules
8 rules, in the community's own words.
- 1
Posts Must Be Open-Source or Local AI image/video/software Related
Posts must center on open-source/local AI tools (e.g. Stable Diffusion, Flux, PixArt). When relevant you should clearly list tools in the title/body and explain your workflow. Mixed workflows are OK only if they center on the use of local or free tools. Using open tools briefly, then switching to paid/proprietary ones (e.g. SD → Kling) is not allowed. News and comparisons are welcome.
- 2
Be Respectful and Follow Reddit's Content Policy
Respect all artists and users. Constructive critique is welcome, but personal attacks, hate speech, trolling, or bad faith arguments are not. Don’t derail threads or provoke others. Debate ideas respectfully. Bashing AI or non-AI art is not allowed. Follow Reddit’s Content Policy: redditinc.com/policies/content-policy
- 3
No X-rated, lewd, or sexually suggestive content
No nudity, lewdness, or sexually suggestive imagery. If it wouldn’t be appropriate for a workplace or younger audience, don’t post it here. NSFW tags are not an exception, stay classy.
- 4
No Gore or Excessive Violence
Content must be suitable for a general audience. Surreal or eerie imagery is fine, but avoid graphic violence, gore, or shock content. Focus on creativity and storytelling over brutality or horror.
- 5
No Politics
No political figures, imagery, or partisan posts. Legislation or policy discussions related to AI are allowed if relevant, respectful, and on-topic. Don’t post memes or images involving politics, even as jokes. Keep the focus on AI generation and creativity
- 6
No Reposts, Spam, Low-Quality, or Excessive Self-Promo
Don't post just to promote yourself or drive traffic to paid tools, services, or downloads. No paywalls, affiliate links, or hidden URLs. Low-effort posts like images/videos without context or workflows are not allowed. Tutorials and tools must be free and directly accessible. Always search before posting to avoid repeat posts about the same thing.
- 7
Use the Correct Flair
Tag your posts with the correct flair (e.g., News, Tutorial, Workflow). This helps users understand the content at a glance and keeps the subreddit organized. NSFW flair may be auto-applied by Reddit’s systems, but that doesn’t mean it bypasses our rules. Use Flairs appropriately and accurately.
- 8
Mod Discretion / Unforeseen Violations
We can’t predict every possible rule-break. Mods may remove posts or ban users for behavior that clearly violates the spirit of the subreddit, even if it's not covered by an existing rule. This includes things like loophole abuse, coordinated disruption, unexpected spam formats, or new types of low-effort content. This rule exists to protect the community from emerging issues and bad-faith behavior. We’ll use it sparingly and with reason. If in doubt, message the mods before posting
What to post in r/StableDiffusion
What fits the room, and what gets removed.
Works well
- A free, directly accessible tool or extension for local AI, with a clear explanation of what it does and how to use it
- A step by step tutorial post with the Tutorial flair, listing every tool used and the full workflow
- A comparison or news post centered on open-source or local AI tools, since the rules explicitly welcome news and comparisons
- A generated image or video shared with complete context, including the tools, settings, and workflow behind it
- A discussion post about a new technique or open-source release that invites others to share their own workflows
Avoid
- Posting an image or video with no workflow or context, since low-effort posts are not allowed
- Sharing a tool or tutorial that sits behind a paywall or is not directly accessible
- Dropping affiliate links, hidden URLs, or links meant to drive traffic to paid tools
- Using open tools briefly and then switching to paid or proprietary ones in your workflow
- Posting anything lewd or sexually suggestive, because NSFW tags do not bypass the rules
- Posting gore, graphic violence, or shock content that would not suit a general audience

What r/StableDiffusion Is For
This community is for people who use open-source and local AI tools for images, video, and related software. The description says you can post art, ask questions, create discussions, contribute new tech, or just browse, and it is up to you. The people here work with tools like Stable Diffusion, Flux, and PixArt, and they care about how things are made, not just the final result. The first rule makes it clear that posts must center on open-source or local AI tools, and mixed workflows are fine only if they center on local or free tools. News and comparisons are welcome too, so this is a working community of creators and builders, not a passive audience.
Rules That Matter Before Posting
The rule that decides most marketing posts is “No Reposts, Spam, Low-Quality, or Excessive Self-Promo”. It says do not post just to promote yourself or drive traffic to paid tools, services, or downloads, no paywalls, affiliate links, or hidden URLs, and tutorials and tools must be free and directly accessible. “Posts Must Be Open-Source or Local AI image/video/software Related” is the other gate, because your post has to center on open-source or local AI tools and explain your workflow. “Use the Correct Flair” is required, so every post needs an accurate tag like News, Tutorial, or Workflow. “No X-rated, lewd, or sexually suggestive content” and “No Gore or Excessive Violence” set hard content limits, and NSFW tags do not bypass them. “No Politics” bans political figures, imagery, and partisan posts, though AI policy discussions are allowed if respectful and on-topic. Finally, “Mod Discretion / Unforeseen Violations” means mods can remove anything that breaks the spirit of the subreddit even when no rule covers it, so keep your post clean and honest.
What To Post
The best shape here is a post that gives before it asks. If you built a tool or workflow around local AI, share it free and directly accessible, and explain the workflow in the title or body. The rules ask you to clearly list your tools and explain your workflow, so treat that as the core of the post, not an afterthought. A tutorial with the right flair, a comparison between open tools, or a new technique you documented step by step all fit what this community is for. If you show generated images or video, include the context and workflow or it will be treated as low effort. If you are unsure whether your post fits, the rules say to message the mods before posting.
What To Avoid
Do not post just to promote yourself or drive traffic to paid tools, services, or downloads. No paywalls, affiliate links, or hidden URLs anywhere in your post. Tutorials and tools must be free and directly accessible, so a gated demo or a paid-only launch post will not survive. Low-effort posts like images or videos without context or workflows are not allowed, so never drop a pretty result with no explanation. Do not use open tools briefly and then switch to paid or proprietary ones, because that pattern is called out as not allowed. Keep everything safe for work, avoid gore and shock content, and stay away from political figures, imagery, or partisan posts, even as jokes. Tag your post with the correct flair, and search before posting so you do not repeat something already covered.
A note from Anthony
What stands out to me is how much this community cares about the workflow itself, not just the final image. The rules ask you to list your tools and explain how you made something, which is a refreshing change from subreddits where a pretty picture is enough. I also like that rule 8 admits mods will act on the spirit of the subreddit when something new shows up, so I would keep any post here unusually clean and transparent.
