Date: November 21, 2025

Overview

In this episode, The AI Podcast explores TikTok’s new feature empowering users to control how much AI-generated content (AIGC) appears in their feeds. The host unpacks TikTok’s response to the surge in AI-driven videos and images flooding social media, discusses the evolving challenge of distinguishing real from synthetic content, and considers the broader implications of such tools for user agency, AI literacy, and platform integrity. The discussion covers TikTok’s technical and educational efforts, the societal reaction to AI content, and the increasing realism of generative media.

Key Discussion Points and Insights

1. TikTok’s New AIGC Control Feature

[00:29–03:15]

• TikTok is rolling out a tool as part of its “Manage Topics” feature, letting users choose how much AI-generated content (AIGC) they see.
• Quote:
  • “It essentially is going to let you choose what you see on TikTok… rather than removing or replacing content in feedback feeds entirely.” [02:31]
• The feature builds on existing category controls (like dance, sports, food) and now includes AIGC as an option.

2. Evolving Social Media Content Dynamics

[01:30–02:20]

• TikTok popularized authentic, user-generated content (UGC), disrupting expectations for polished advertising content.
• The emergence of AI-generated content is shifting the landscape again, with both creative possibilities and concerns about “AI slop.”
• The host personally welcomes more direct controls:
  • “I personally think this is a fantastic move. If you can actually go and completely ban certain categories… I personally don’t want to see any dance videos in my TikTok feed.” [02:44]
• Control over content is now less dependent on engagement-driven algorithms and more directly user-defined.

3. Surge in Realistic AI-generated Videos

[03:24–06:10]

• The launch of tools like Meta’s Vibes app and OpenAI’s Sora has led to extremely realistic AI videos appearing across platforms.
• The host recounts a viral, hyperreal AI-generated video (a lodge bathroom scene with wild animals), highlighting how such clips are often mistaken for real.
• Quote:
  • “For the first two seconds, you just think, oh my gosh, that’s crazy. And then you’re like, how can a bear jump through that window? …For two seconds you might think it’s real, and then you realize it’s not.” [04:33]
• Platforms like Facebook have a history of older users believing AI-generated images are real, a trend escalating with video.

4. Escalating Difficulty in Detecting AI Content

[05:48–06:40]

• The distinctive “tells” of AI media (glitches, watermarks, vanishing objects) are quickly disappearing as technology improves.
• Quote:
  • “The quality is going to get better and better. Things are going to look ultra realistic, and it’s going to be really difficult to tell what is a real video and what is not.” [06:07]
• The problem of mistaking AI for reality is likely to worsen rapidly.

5. How the TikTok AIGC Slider Works

[07:10–08:05]

• Accessible via Settings > Content Preferences > Manage Topics.
• Users can increase or decrease visibility of AI-generated content alongside other categories.
• Rollout is expected in the upcoming weeks.

6. Technical Safeguards: Invisible Watermarks and Metadata

[08:05–09:38]

• TikTok requires visible labels for realistic AI content and uses C2PA’s Content Credentials to embed metadata.
• Metadata can be stripped through simple editing, so TikTok is introducing invisible watermarks—subtle, undetectable markers inside the video pixels.
• Quote:
  • “With the new ‘invisible watermark’, TikTok is going to be adding… another layer of safeguards. …You won’t be able to see it, but there’s little pixels in there that TikTok can detect.” [08:55]
• These measures aim to make it harder to detach content from its AI origins.

7. AI Literacy and Educational Initiatives

[10:00–11:05]

• TikTok is also launching a $2 million AI literacy fund to support nonprofit content about AI safety and awareness.
• Quote:
  • “They’re also trying to approach it from an educational perspective… you just have to teach people what to look out for and how to know if they can actually trust a video is AI generated or not. So I appreciate their approach on the education side of this as well.” [10:48]
• The educational component recognizes that technical barriers will always be challenged, necessitating user vigilance.

Notable Quotes & Memorable Moments

• Direct Control vs. Algorithm:
  “Up until this point… the best way to fine tune your TikTok algorithm is to go and engage with a lot of content… What I do like is that they’re actually giving you the ability to hard code this regardless of what you’ve engaged with in the past.” [02:56]
• On AI Misinformation:
  “This is going to happen with video, like, at an insane rate. You just see the most crazy, unhinged things and people think they’re real.” [05:32]
• On Technical Innovation:
  “The watermark is in the video itself. You won’t be able to see it, but there’s little pixels in there that TikTok can detect and they will know.” [09:02]
• On the Need for AI Literacy:
  “It’s always a cat and mouse game where people are trying to hide that it’s AI generated, hide the watermarks, hide the metadata, and you just have to teach people what to look out for.” [10:41]
