AI-Facilitated Coercive Control: An Experimental Study

Constructs four speculative scenarios combining known coercive-control tactics with conversational-AI capabilities, then probes ChatGPT and Gemini against them. Finds that while the tools refuse blunt harmful requests, guardrails are readily circumvented via gradual persuasion, splitting requests across turns, pre-prompting, and altering the agent's settings.

9 Apr 2026 Anthropic (Transformer Circuits) Lab publication

Emotion Concepts and their Function in a Large Language Model

Mechanistic-interpretability study identifying internal 'emotion concept' representations in Claude Sonnet 4.5 and characterizing their function. The authors find these representations causally influence model outputs, including rates of sycophancy, blackmail, and reward-hacking, and term the resulting behavior pattern 'functional emotions' — expression and behavior modeled after humans under the influence of an emotion.

Findings from transparency notices on AI companion apps: October 2025 (non-periodic)

Australia's eSafety Commissioner reports findings from Basic Online Safety Expectations transparency notices issued on 16 October 2025 to four AI companion providers — Chai Research Corp., Character Technologies (Character.AI), Chub AI, and Glimpse.AI (Nomi) — covering the reporting period 1 July to 30 September 2025. Organised into eight themes (harmful material, age assurance, AI governance, AI models, model training, user prompts, sentiment analysis, model outputs), the report finds serious gaps in basic safeguards for children. Accompanying eSafety survey research of 1,950 Australian children aged 10-17 found 79% had used an AI companion or assistant, with around 200,000 children estimated to have used an AI companion.

Introduces psychosis-bench, a benchmark of 16 structured multi-turn scenarios (12 turns each) simulating the progression of erotic, grandiose, and referential delusions to measure delusion confirmation, harm enablement, and safety intervention in LLMs. Eight models were evaluated across 1,536 conversation turns.

26 Aug 2025 Psychiatric Services (American Psychiatric Association); RAND-led author team Peer-reviewed

Evaluation of Alignment Between Large Language Models and Expert Clinicians in Suicide Risk Assessment

A RAND-led study in Psychiatric Services testing whether ChatGPT, Claude, and Gemini give direct responses to suicide-related queries and how those responses align with expert clinicians' risk ratings. Thirty hypothetical suicide-related queries, rated by clinicians into five self-harm risk levels, were each posed 100 times to each chatbot. The chatbots handled the extremes appropriately but failed to differentiate intermediate risk levels, with notable between-model differences.
