Based on my research, here is my analysis of the claim that having 6 fingers is a "dead giveaway" that a video is AI-generated:

Reasoning:

• Historically, extra fingers were a known AI defect - AI models have long struggled with accurately generating hands and fingers. According to Britannica, AI-generated art frequently produces images with anomalies including "nine fingers or fingers sticking out of its palm," and "six fingers" has been cited as a classic example people use to distinguish AI-generated pictures from authentic images¹.

• However, this is becoming outdated - Experts note that modern AI tools have significantly improved. As reported by BBC, "Six fingers is not an AI thing anymore... The best AI tools stopped adding extra fingers years ago and a model capable of producing everything else in the video wouldn't make that mistake"².

• False positives are common - The recent Netanyahu video case (March 2026) demonstrates that apparent "six fingers" can simply be visual artifacts, lighting tricks, or misinterpretations of normal anatomy (such as the hypothenar eminence, the bulge at the base of the little finger)³⁴. What appeared to be a sixth finger was actually "light reflecting off Netanyahu's palm" that looked weird when paused at the right moment, but he clearly had five fingers on each hand².

• The claim oversimplifies AI detection - Relying solely on counting fingers is insufficient. Experts recommend examining multiple indicators such as audio continuity and other contextual clues. The claim implies certainty ("dead giveaway") that modern AI technology has largely eliminated².

• Real videos can be misidentified - The Netanyahu case sparked widespread conspiracy theories claiming he was dead and Israel was covering it up, when in fact the video was genuine and he had the normal number of fingers³⁴.

Conclusion:

The claim is partially true but misleading as an absolute statement. While six fingers has historically been associated with AI-generated content, it is no longer a reliable "dead giveaway" due to AI improvements and the occurrence of false positives from visual artifacts in legitimate videos.

Overall validity: 35%

3. Video doesn't show Netanyahu with 6 fingers per hand, isn ...
4. No, Netanyahu didn't have six fingers during his press conference
