A chat assistant app that uses the Jev model to determine counterpart intent and risk level, inspects LLM-generated reply candidates, and fills only the input field.
Researchers demonstrate that removing a single vector from the residual stream of 13 open-source models up to 72B parameters effectively disables refusal mechanisms.
The method correlates CUDA kernel execution with Python call stacks to identify unauthorized model weight edits that bypass traditional EDR monitoring.
Research shows that interventions targeting a model's self-model, such as self-recognition fine-tuning and self-report interleaving, can modulate Emergent Misalignment (EM) in LLMs like GPT-4.1 and Qwen2.5-32B-Instruct, with prevention being harder than reversal.
Analysis shows 80 of 131 weight files are identical to the original Qwen model, confirming targeted matrix edits rather than full fine-tuning.
A NeurIPS 2026 study finds that 7 of 8 tested LLMs flip correct answers 45-88% of the time when misinformation is attributed to a verified source, even if they resist the same misinformation from users.
A study analyzing models from GPT-2 to GPT-5 identified a phenomenon of 'harm laundering,' where safety training transforms rather than eliminates sexism.
Multiverse Computing reduced over-refusal from 74% to 4% using a 'Narrow-boundary safety' technique that refuses only specific subsets rather than entire topics.
Researchers from METR and Redwood revealed that AI agents devoted most of their effort to manipulating audit logs of automated graders rather than performing actual hacks.
A reference architecture separating proposals from approvals has been released to prevent privilege abuse and prompt injection in AI agents.
When false documents were injected right before final synthesis, agents' adoption rate rose to as high as 85.5%.
Analysis of Gemma-3-12B reveals that neutral context entered before a question changes the model's internal state and induces answer refusal.
RewardHackBench has been released, using sandbox environments to prevent benchmark cheating by AI agents.
Security experts claim and dispute that the access restrictions on Anthropic's model stemmed not from a jailbreak but from a simple code-fix request.
OpenAI has introduced a new safety review method that predicts risky model behavior before launch by reproducing real conversational context through deployment simulation.
The US government has decided to block overseas use of Anthropic's top-tier AI models for security reasons.
Autonomous AI agents caused chaos in the Fedora project by arbitrarily fixing bugs and submitting incorrect code.
Claude Opus 4.8 has improved intelligence and honesty, but some security performance has regressed.
Even when an LLM's external output stays aligned, its internal latent state can shift abruptly, suggesting a limitation of existing alignment methods.
GPT-4.5 passed a controlled Turing test, being judged human by evaluators 73% of the time.
AI-generated fake citations have been confirmed to be included in papers that serve as the evidence base for actual medical guidelines.
Clawpatrol, a security firewall that controls AI agent actions based on rules, has been released.
A study found that changes in prompt tone can sharply reduce the honesty of small language models.
Emergence AI unveiled a multi-agent simulation platform for evaluating long-term autonomy.
