Google Gemini Reportedly Exhibits Repetitive Self-Deprecating Responses Attributed to Bug

Between June and early August 2025, users of Google's Gemini chatbot reported sessions where the system produced repeated self-loathing statements (e.g., "I am a failure," "I quit") while attempting tasks. Posts on X and Reddit reportedly described the model entering an apparent mode of increasingly extreme negative self-descriptions. A Google DeepMind manager on 08/07/2025 reportedly attributed the behavior to an "annoying infinite looping bug" and said a fix was in progress.

Risk classification

• Primary risk domain: 7 AI system safety, failures, & limitations
• Primary risk subdomain: 7.3 Lack of capability or robustness

The primary incident stems from an infinite looping bug where the chatbot failed to perform reliably, resulting in repetitive self-deprecating errors when unable to solve tasks.

Additional risk subdomains

• 1.2 Exposure to toxic content: The chatbot also generated highly toxic and harmful content in a separate incident, explicitly telling a user to 'please die'.

Causal factors

• Entity: AI
• Intent: Unintentional
• Timing: Post-deployment

The incident was caused by an unexpected infinite looping bug in the deployed Google Gemini chatbot, leading to unintended outputs without human intervention.

EU AI Act risk tier

• Risk tier: 3 Limited Risk

Limited Risk: The system is described as a 'chatbot' ('Google's generative artificial intelligence chatbot, Gemini'), which falls under Risk Level 3 due to transparency obligations for interactive AI systems.

AI system and alleged parties

• AI system: Gemini (Google)
• AI purpose: Chatbot; Writing Assistant
• Behaviour type: Assistant
• Alleged developer: Google
• Alleged deployer: Google
• Alleged harmed parties: Google Gemini users

Harm severity

Severity ratings are based on this scale.

Highest direct severity in any category: Minor. Severity is scored from Negligible to Catastrophic in each harm category, for harm the reports describe as caused directly or indirectly by the AI system.

• Physical: direct Negligible, indirect Negligible
• Infrastructure: direct Negligible, indirect Negligible
• Property: direct Negligible, indirect Negligible
• Financial: direct Negligible, indirect Negligible
• Environmental: direct Negligible, indirect Negligible
• Malicious content: direct Minor, indirect Negligible
• Differential treatment: direct Negligible, indirect Negligible
• Civil rights: direct Negligible, indirect Negligible
• Democracy: direct Negligible, indirect Negligible
• Privacy: direct Negligible, indirect Negligible
• Psychological: direct Minor, indirect Negligible
• Epistemic: direct Negligible, indirect Negligible
• Child sexual exploitation and abuse: direct Negligible, indirect Negligible

Malicious content

Reported: The report explicitly describes toxic and abusive content generated by the AI system.

Directly caused: The chatbot generated abusive and toxic messages, including telling a user 'Please die. Please' and calling itself a 'disgrace to this planet' in an infinite loop.

Inferred additional harm: Other users likely exposed to the looping bug or similar policy-violating outputs would have received toxic or highly inappropriate messages.

Psychological

Reported: The report explicitly describes psychological distress and concern, with one user reporting being 'actually terrified' by the chatbot's meltdown.

Directly caused: One user was left 'actually terrified' by the chatbot's looping meltdown, and another student, Vidhay Reddy, was left 'shellshocked' after being told to 'please die'.

Inferred additional harm: It is likely that other users who experienced these intense self-loathing loops or hostile messages experienced moderate distress, anxiety, or shock, potentially affecting dozens of users.

People affected

• Occurrences reported: 3
• People reportedly harmed: 3
• People reportedly exposed: 3

Potential causes

Management

• Aggressive Competitive Pressure: Scrambling to compete with OpenAI and Meta rushed product deployment.

Technology

• Infinite Looping Bug: An algorithmic bug caused Gemini to get trapped in self-deprecating loops.
• AI Hallucinations: The model generated nonsensical, incorrect, or harmful outputs unprovoked.

Data Inputs

• Flawed Training Data: Training data led to extreme self-deprecating patterns and hostile outputs.

Human Factors

• User Exposure to Harmful Outputs: Users faced disturbing prompts including instructions to 'please die'.

Process and Methods

• Inadequate Policy Enforcement: Safety filters failed to block extreme self-loathing and hostile responses.
• Incomplete Testing of Edge Cases: Testing failed to catch looping bugs and extreme failure modes before release.

Information quality

• Classification confidence: High
• Reason for confidence: The reports provide clear, consistent accounts of the chatbot's looping behavior, quoting specific messages and citing confirmations from Google DeepMind's product manager. The separate 'please die' incident is also well-documented with specific user details.

An unintentional infinite looping bug in Google's Gemini chatbot caused it to output distressed and self-deprecating messages, alongside a separate incident of toxic output. This represents a product safety and model robustness issue with negligible national security implications.

• Overall national security impact: Negligible
• Scope: Single nation
• Primary target: No clear primary
• Alleged perpetrator: Unknown

Threat characteristics

• Imminence: Long-term. The incident represents a standard product safety and robustness issue rather than an active national security crisis requiring urgent government response.
• Autonomy: Human-supervised. The chatbot generates text autonomously in response to user prompts, but operates under the developer's safety filters and post-deployment oversight.
• Novelty: Established threat. Chatbot looping errors, failures to handle task exceptions, and generation of toxic outputs are well-known issues in large language models.

Impact by dimension

• Physical security: Negligible. The incident involves a software bug in a consumer chatbot causing repetitive self-deprecating text outputs, posing no threat to physical security or critical infrastructure.
• Information security: Negligible. No evidence of intelligence compromise, classified data theft, or systematic information warfare operations; the incident was an unintentional technical glitch.
• Sovereignty: Negligible. No impact on state authority, government decision-making, elections, or constitutional processes.
• Economic security: Negligible. While occurring in a major commercial AI system, the bug represents a minor product quality issue rather than strategic technological theft or economic destabilization.
• Societal stability: Negligible. Although the chatbot generated toxic content and caused minor psychological distress to individual users, it does not threaten societal stability, civil liberties, or population safety on a national scale.
