What happened

The Texas Attorney General announced a settlement with Pieces Technologies following allegations that the company misrepresented the accuracy of its healthcare AI systems used for clinical documentation. The state concluded that marketing claims about low error and hallucination rates may have misled hospitals and clinicians relying on the tools in patient care settings. The settlement imposed restrictions on future claims and required greater transparency around performance and risk.

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....
