Daily Challenge Rules Update

At NightCafe, we're committed to promoting creativity and providing a level playing field for all challenge participants. That's why we're making some changes to the daily challenge rules, which we believe will help to achieve these goals.

First, we want to explain why we're making these changes.

One of our main goals with challenges is to make them fair. What we've found is that quite often, the creations that do best in challenges use a start image that wasn't created on NightCafe.

A few months ago, we introduced some automated checks to ensure that submitted images are significantly different to start images. Those changes helped for a while, but we're still finding that a lot of highly-rated challenge entries used a start image that doesn't look all that different to the submitted image.

There's also the issue of false positives when moderating start images. It's frustrating as a user to have your entry rejected by the automoderator or by one of our human moderators for being too close to the start image, when you know the start image was legitimate. Neither the automoderator  or our human moderators are perfect - both make mistakes. And it feels really bad to have something you spent a lot of time creating rejected by a moderator in error. The rules need to be less ambiguous and easier for us to enforce in moderation.

We want to make sure that everyone has an equal opportunity to participate and showcase their creativity, regardless of their level of experience on NightCafe, or the AI Art generating tools they use. 

With that in mind, we're introducing new criteria for challenge submissions that will help to level the playing field and promote creativity, putting more focus on prompting rather than start images.

So what are the changes?

  • Entirely your own: You can't submit a creation that was a duplicate or evolution of another user's creation at any point in the chain of evolutions/duplications.
  • No start images: You can't submit a creation made from an image that wasn't originally created on NightCafe, regardless of whether the image belongs to you, is public domain, etc. The exception of course is evolutions - which use a previous creation as the start image. Evolutions are allowed as long as no external start image was used at any point in the evolve chain.
  • No Style Transfer creations: You can't submit a creation made using the Style Transfer Algorithm or that is descended from a style transfer creation.
  • No deleted creations: You can't submit a creation if the chain of evolutions/duplications contains a deleted creation. Once a creation is deleted, our moderators can't confirm that it followed all the above rules.

We believe that these changes will help to promote creativity and originality, while also leveling the playing field for all of our challenge participants and making the rules less ambiguous and easier to enforce. We know that change can be challenging, so we want to give you all the information you need to succeed.

We hope that these changes will encourage everyone to create something unique and original for our challenges. We're excited to see what you come up with!

If you have any questions or concerns, please don't hesitate to reach out to our team via the Feedback/Support form here.

  • So I feel that this new regulation is completely fair, logical and also transparent, because it is called “challenge”, not “who has the best starting image”. Let’s be honest: It is sometimes damn easy to generate an equally perfect result from a perfect starting image. That’s really no feat. Ultimately, it’s about exploiting the potential of AI and its possibilities. In the end, using a perfect source image would not be much more than simply placing an art filter over an image. As a freelance artist, I welcome the fact that, as part of a challenge like this, images generated exclusively by the AI of NightCafe compete against each other.

  • IMHO this is the best change so far. Especially the last text challenge made it very clear that start images are a fairness issue.

    There is just one small exception that I would like you to think about: There is a small backdoor in the “creations by you” statement! because you could manually copy prompts and settings and get away with it.

    Perhaps it would be better to allow the evolution of other creations that otherwise follow all the rules (perhaps by adding a tag) to be more transparent at the start. Of course, this might lead to other kinds of difficulties and might not solve the problem entirely.

  • I fully welcome these changes. I have only recently started participating in the challenges, and my submissions are solely based on prompts. Whenever I look at the winners from previous days, it looks obvious that many of them have used starter images as base models.

  • these new rules dont really change anything for me, strangely enough, I have been abiding to these changes since I joined, lol

  • Hi, when I evolve and duplicate many images of mine as requested, I finally have a lot of useless jobs. If I want to make some order and delete the useless ones, I can make an error and delete a step image. So either I keep or archive all of them and keep the mess either I spend a lot of time to study the evolution. I think it would be great if you could flag that an image has been started only with a prompt and have the evolutions inherit the flag. Or add an icon to the images that are involved in evolutions. Thanks.
