On web, mobile browser, PWA, APK, or desktop, you can disable the Mature Filter on a Pro plan or higher:
Open Settings (sidebar → profile → Settings).
Go to General.
Turn Mature Filter off.
You can also reach it from the model selector. Turning Mature Filter off changes what the UI shows, but it does not override an individual model's own content behavior or a third-party provider's content policy.
On the iOS and Android App Store apps, the Mature Filter is forced on for App Store policy compliance. Turning it off in account settings will not fully apply inside those App Store apps. Use web, mobile browser, PWA, APK, or desktop for the less-restricted experience.
