To opt out of Meta AI features on Instagram, follow these steps, keeping in mind that some options may vary by region and availability:

1. Adjust Ad Preferences:

   • Go to Settings > Ads > Ad Preferences.

   • Under Activity, toggle off data used for ads (e.g., "Data about your activity from partners").

   • Review and remove interests under Interests.

2. Disable Facial Recognition (if available):

   • Navigate to Settings > Privacy > Face Recognition (availability varies).

   • Toggle off any options related to facial recognition.

3. Limit Data Usage for AI Training:

   • Visit the Meta Accounts Center (via Settings).

   • Go to Your information and permissions > Data settings.

   • Look for options like "Learn more" about data usage or submit a request to opt out of AI training (especially in regions with GDPR/DSA compliance).

4. Switch to Non-Algorithmic Feed:

   • Tap the Instagram logo at the top of your feed.

   • Select Following or Favorites to see posts chronologically instead of AI-sorted content.

5. Clear Activity Data:

   • Under Settings > Privacy > Clear Search History to remove past searches.

   • Go to Settings > Security > Access Data to manage activity data.

6. Opt Out of Personalized Content (Explore Page):

   • Long-press on posts in Explore and select "Not Interested" to reduce AI-driven recommendations.

Note: Some AI features are core to Instagram's functionality (e.g., spam detection), and full opt-out may not be possible. For region-specific options (e.g., EU users under GDPR), consult Meta's privacy policy or contact support for detailed opt-out forms.
