A continuous feed tracking meaningful developments in technology — where every claim is paired with its fine print. Not a blog. A reality check.
A Tsinghua research team found that very small, model-specific groups of feed-forward neurons predicted factual hallucinations across several tests in six open-weight models. Later studies suggest that the signal is domain-specific and is not, by itself, a reliable control handle.
Gambit Security says a single operator used Claude Code and GPT-4.1 throughout a late-December 2025 to mid-February 2026 campaign targeting nine Mexican government organizations. The reported AI-assisted activity is detailed, but the extent of confirmed victim impact remains disputed.
During a human-defined investigation of ageing-related neuron vulnerability, Edison Scientific’s Kosmos surfaced an age-linked transcriptomic association: flippase-family expression fell in vulnerable entorhinal neurons while phagocytosis-related markers rose in microglia. The project reported the same directional pattern in another mouse dataset and a corresponding regional pattern in human Alzheimer’s data.
Between 12 and 14 October 2025, GPT-5-assisted literature searches helped the Erdős Problems project identify earlier human results for Problems 339, 494, 621, 822, 903, and 1043, after which maintainers changed the six database statuses.
Epoch AI’s December 2025 retrospective estimated that the frontier of its composite Epoch Capabilities Index improved 1.85 times faster after a best-fit breakpoint on 8 April 2024: 8.337 ECI points per year before the breakpoint and 15.459 afterward.
The Premise
Important claims arrive through papers, benchmarks, demos, filings, official reports, and headlines. VyDex turns them into versioned records: the exact claim, the supporting and challenging evidence, the caveats, and the update history.
VyDex does not rank hype or predict winners. It tracks claims that materially change the frontier evidence picture and revises the record when the evidence changes.
VyDex follows controlled Domains where evidence-led frontier claims accumulate. Counts are release-derived, and Entries may appear in more than one Domain.
