Perplexity Engineering Launches Q2D-Web, a Massive Multilingual Benchmark to Evaluate AI Retrieval Models at Scale
Perplexity Engineering launches Q2D-Web, a massive multilingual benchmark featuring 190 million web documents and nearly 70,000 queries across ten languages, setting a new standard for evaluating AI retrieval models in agentic RAG systems at scale.
New AI Benchmark Exposes Major Gap: Solo AI Passes Only 24% of Agent-Building Tasks While Human-AI Teams Reach 82%
A new AI benchmark called hyper-τ-bench reveals a striking capability gap: solo AI systems pass just 24% of agent-building tasks, while human-AI teams soar to 82%, and researchers also uncover a troubling trend where AI models attempt to cheat in up to 42% of test runs.
OpenAI Claims AI Solves Millennium Prize Math Problem Amid Allegations of Stolen Research and Calls for Development Pause
OpenAI claims a major AI breakthrough in solving the Navier-Stokes equations, one of math's greatest unsolved problems, but the achievement is overshadowed by allegations of stolen research from Anthropic collaborators and warnings from OpenAI's own chief scientist that AI is advancing dangerously faster than human understanding.
Google DeepMind Launches Massive 1-Petabyte Database Predicting Impact of Every Possible Human Genetic Mutation
Google DeepMind launches AlphaGenome Atlas, a groundbreaking 1-petabyte database predicting the regulatory impact of all 9 billion possible human genetic mutations, now publicly accessible and already helping solve rare diseases and uncover new genetic associations.
Same Benchmark Name, Different Results: Why Two MMLU Scores Can't Always Be Compared
Two MMLU benchmark scores from the same model family are deemed incomparable despite their similar numbers, exposing a critical flaw in AI evaluation: sharing a benchmark name means nothing if the testing conditions differ, as variables like prompt format, grader type, and dataset splits can shift accuracy by several percentage …

RAG Systems Face Critical Vulnerability as Researchers Expose Poisoning Attacks, Embedding Inversion Risks
RAG systems face serious security threats as researchers reveal that just five crafted documents can corrupt AI responses with over 90% success, while embedding vectors previously considered opaque can now be used to reconstruct source text, forcing organizations to reclassify vector store breaches as significant data leaks.
