CRITICAL BUG: Video ID Collision / Split-Brain Retrieval for YouTube ID MdeQMVBuGgY

Draft Bug Report

I have discovered a “split-brain” bug in Gemini’s YouTube retrieval tool where a specific Video ID resolves to two completely different videos depending on the request source.

The Conflict:

Video ID: MdeQMVBuGgY

Public Internet (User Side): Resolves to “Vijay Mallya Podcast: Rise & Downfall… | Raj Shamani” (Verified via Browser, Python requests, and VPNs in India & Netherlands).

Gemini Internal System: Resolves to “How To Start A $10k/Month AI Agency… | Iman Gadzhi”.

The Issue:

When I provide the link Gemini’s internal tools fetch metadata for the Iman Gadzhi video and generate a summary for that content, while I am viewing the Raj Shamani video on the actual YouTube platform. This leads to Gemini insisting the user is wrong despite irrefutable evidence.

Evidence & Reproduction:

I ran a Python script (using requests) to query the ID MdeQMVBuGgY from multiple IP locations (India and Netherlands). In all public instances, it returns the Raj Shamani video title. However, Gemini’s internal logs (visible in our chat) show it retrieving the Iman Gadzhi video title for the exact same ID.

Chat Session Proof:

Requested Action:

Please investigate the backend database or cache for MdeQMVBuGgY as it appears to have a hash collision or corrupted entry in the internal Google/YouTube cache used by Gemini.

Hi @Lalitmehta, welcome to the community!

I went through your chat session and tried it out myself using the exact prompt you have sent. Unfortunately, I got the proper video “Vijay Malya podcast with RajShamani“ with the ID MdeQMVBuGgY.

Even tried deliberately asking if it was different, but every time it’s the same and correct response.

So, maybe it was a temporary thing. Can you please try the same one more time?

Thank you!

Thanks for checking this out!

It definitely wasn’t a temporary glitch on my end—I spent hours verifying it with Python scripts and VPNs, all of which confirmed the backend conflict.

Update: The behavior has changed.

Since I filed this report, I haven’t been able to reproduce the original “hallucination” bug.

Previously: It would instantly give the wrong summary (Iman Gadzhi).

Now: When I paste the link, I see the “Connecting to YouTube” animation, it pauses/troubleshoots for a moment (doing extra verification steps it didn’t do before), and then finally delivers the correct Raj Shamani summary.

I actually recorded my screen [https://drive.google.com/file/d/1uxlsVFY72w0svnS2yRNWR7s4oz4Js7OU/view?usp=sharing\] trying to recreate the bug for you, but I couldn’t get it to fail again—it seems the system is now detecting the conflict and correcting itself in real-time, or the bad cache entry has finally been flushed.

So while it works now, the original “Split-Brain” issue where the ID MdeQMVBuGgY pointed to two different videos was definitely real!

:light_bulb: A Cheerful Suggestion for the Team:

"Why not add a Quote Reply feature like WhatsApp? :speech_balloon:

It would add a massive layer of context awareness to Gemini. To be honest, while Gemini has significantly improved over the last few months in reasoning and overall prompt generation, the context awareness still kind of struggles sometimes. A simple quote function would help the model know exactly what part of the conversation I’m referring to—and avoid bugs like this in the future!"
