What happened

During the Iran war, Grok reportedly told users that a café video posted by Israeli Prime Minister Benjamin Netanyahu was AI-generated or a deepfake, after the clip was released to counter rumors that he was dead or injured. Reuters verified the video's location and date and later reported that Netanyahu publicly dispelled the death rumors. Reports said Grok's answers amplified doubts about the clip.

Risk entries describing this failure mode

Entries from the MIT AI Risk Repository coded to subdomain 3.1.

  • Pursuing Consistent Context

    "LLMs have been demonstrated to pursue consistent context [129]–[132], which may lead to erroneous generation when the prefixes contain false information. Typical examples include sycophancy [129], [130], false demonstra...

  • Defective Decoding Process

    In general, LLMs employ the Transformer architecture [32] and generate content in an autoregressive manner, where the prediction of the next token is conditioned on the previously generated token sequence. Such a scheme...

    "Another important source of hallucinations is the noise in training data, which introduces errors in the knowledge stored in model parameters [111]–[113]. Generally, the training data inherently harbors misinformation....
