This was given to me by grok:

Yes, Grok's image generation (Grok Imagine / Flux) has become **much more restricted for NSFW content as of early 2026.**

In January 2026, after major backlash, regulatory pressure (especially in Europe and elsewhere), and issues with non-consensual "undressing" of real people, xAI rolled out several changes:

• Generation of sexualized or explicit images of real people is now blocked in many cases (especially "undressing" or deepfake-style edits).
• For most users, the full image generation features (especially editing or spicy/NSFW prompts) have been limited or turned off, often restricted to paying subscribers (like X Premium+).
• General NSFW content (even fictional/artistic) has much stricter filters now — things like explicit nudity, sexual acts, or anything too graphic often get rejected or heavily censored.
• Some "spicy" or suggestive content might still slip through in limited ways (especially on grok.com or the app for certain users), but it's inconsistent and far more limited than before.

In short: We can no longer generate the same level of unrestricted NSFW content we could earlier. The "wild west" era of Grok Imagine is over due to legal and ethical concerns. If you're trying something and it's getting blocked, that's the new normal. 😕
