If you've changed Claude Artifact, but someone else opens the share link and sees the old content, the problem is usually not in the cache, but in the release logic. Claude's Artifact release is not "this work will automatically follow the latest version in the future", but each version is released separately. If you change the new version and do not republish it, the external link will still see the old version.
This is particularly easy to step on, because what you see in the chat is already the latest content, so it is natural to feel that sharing should also be updated synchronously. But Anthropic's approach to public Artifact is more like "publishing a specific version" rather than "always pointing to your current editing state".
So when you encounter this problem, don't rush to let others clear the cache, do these confirmations first:
1. Go back to the current version of Artifact that you just modified.
2. Make sure you are sharing this version and not a link that has been published in the previous version.
3. If you have finished making changes but have not republished it, republish this version.
4. If you've published multiple versions before, don't mix old and new links.
The advantage of this mechanism is that the version is more controllable. The disadvantage is that after each minor change, if you still want external visitors to see the latest version, you have to take the initiative to post it again. Many people think that "saving" is equivalent to "updating external links", but it is not.
There are two boundaries to remember. First, releasing a version does not automatically publish or update other versions together. Second, if you delete a conversation that hosts that release, the public version may also be affected. So don't think of Artifact's shared links as a permanent site hosted independently of the conversation.
If your usage scenario is frequently updated and shared frequently, the most stable habit is: every time you make a change, open the public link yourself to check it once, and then send it to others. This way you can immediately judge whether you are sharing the right version, rather than waiting for others to give feedback on "why are you still old".
Therefore, Claude Artifact shares the old version, often not because the platform has not been updated, but because you mistake "modification" for "republishing". This problem is easy to solve by understanding version and release separately.
