A new study introduces the Guided-Retry strategy to reduce AI hallucinations in task-oriented dialogues without retraining models. Tested on models like DeepSeek-R1 and Llama-3, the method cut hallucination rates by up t…
New research reveals that EU copyright law, which protects creative essence beyond verbatim copying, outpaces current AI safeguards. The PSALM framework evaluates LLM outputs for stylistic and narrative similarities, exp…
Researchers introduced Triospect, a new AI-text detection framework that improves detection accuracy by 22.3% AUROC and 13% TPR01 on the Humanize-16K dataset, and shows resilience against sophisticated attacks. The frame…
Researchers introduced LoFa, a new benchmark to evaluate large language models' resistance to logical fallacies, revealing inconsistent robustness across models. The study highlights the risk of deploying AI systems vuln…
Researchers introduced CORTEX, a new method for detecting hallucinations in AI-generated text at the token level within Retrieval-Augmented Generation (RAG) systems. By analyzing internal model representations with and w…
Users are experiencing delays and stability issues with Claude's command classifier since this morning. The classifier is briefly unavailable, and the claude-opus-4-8 model is temporarily unavailable for PR inspection, p…
San Jose police declared an unlawful assembly Tuesday night as soccer fans celebrating Mexico's World Cup win over Ecuador gathered downtown, ordering the crowd to disperse or face arrest and possible use of force. The c…
European Technology Commissioner Henna Virkkunen and Apple CEO Tim Cook held a constructive video call on Monday, discussing topics of mutual interest, a Commission spokesperson said Wednesday. The call comes amid tensio…
Anthropic's Fable 5 is back on the global market after a two-week ban by the US government over a jailbreak exploit discovered by Amazon researchers. Anthropic claims smaller models like Claude Haiku 4.5 could also execu…
The US Commerce Department lifted export controls on Anthropic's Claude Fable 5 and Mythos 5 models, ending a three-week freeze that had pulled the models offline. The reversal came after Anthropic agreed to proactively …
Tommy Jepsen argues that the claim '100% of our code is written by AI' obscures a critical distinction between supervised AI code generation, where a human reviews and approves the diff, and unsupervised generation, wher…
A new analysis explores how weight quantization affects model performance and sparse autoencoder (SAE) reconstruction of the residual stream, using fraction of variance unexplained (FVU) as a key metric. The study, inspi…
Researchers introduced Modality-Agnostic Refusal Steering (MARS), a method that uses text-based refusal strategies to enhance safety in multimodal language models without requiring unsafe multimodal data. Evaluations acr…
Researchers have identified linguistic bias as a critical vulnerability in voice biometrics spoofing detectors, which perform poorly on diverse real-world data. A new framework using teacher-student adversarial learning …
Researchers have developed a new framework for detecting backdoor attacks in large language models, addressing the challenge of discrete input spaces. The framework introduces Class Subspace Orthogonalization (CSO) to en…
Researchers have developed a compact fingerprint model for AI skill identity that uses locality-sensitive hashing to preserve skill relationships, achieving 0.974 AUC on pairwise comparisons with 77 times fewer bits than…
The White House has lifted its ban on AI models developed by Anthropic, reversing a previous restriction. The decision marks a shift in the administration's approach to AI regulation and oversight.
Anthropic restored its AI model Fable 5 after government intervention, implementing co-developed safeguards and a 50% weekly usage cap until July 7.
Anthropic's Claude Agent SDK introduces Hooks, a feature that enforces deterministic guardrails on AI agents by blocking destructive commands, injecting live context, and enabling auditing, without asking the model for p…
The Linux Foundation launched Akrites, a coalition including Anthropic, AWS, IBM, Microsoft, Nvidia, OpenAI, and others, to defend open-source software from AI-driven vulnerability discovery. The group will fund a shared…
