Anysphere AI Support Bot for Cursor Reportedly Invents Login Policy, Leading to Subscription Cancellations
What happened
In April 2025, users of Cursor, an AI-powered coding assistant developed by Anysphere, reported being logged out unexpectedly. An AI-powered support bot, "Sam," allegedly responded with an invented login policy to justify the behavior. The hallucinated policy was not based on any real company change. The incident reportedly led to subscription cancellations.

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...
- Knowledge Gaps
"Since the training corpora of LLMs can not contain all possible world knowledge [114]–[119], and it is challenging for LLMs to grasp the long-tail knowledge within their training data [120], [121], LLMs inherently posse...
- Hallucinations
"LLMs generate nonsensical, untruthful, and factual incorrect content"
- Faithfulness Errors
"The LLM-generated content could contain inaccurate information" which is is not true to the source material or input used
- 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...
- Untruthful Content
"The LLM-generated content could contain inaccurate information"
- Factuality Errors
"The LLM-generated content could contain inaccurate information" which is factually incorrect
- Noisy Training Data
"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....
