Anthropic will embed invisible watermarks in all future Claude models, effective August 2, 2026, to comply with the EU AI Act. The method, based on Google's SynthID, has no practical impact on output quality and adds no cost.
Grok 4.6 scores 61 on Artificial Analysis, overtaking Kimi K3 and matching GPT-5.6 Sol for world's third best. Focuses on long-running agents, coding, and knowledge work with a pricing strategy to lower costs.
A model trained with RLVR on Tinker achieved state-of-the-art on BIRD, scoring above the human mark of 92.96%. The work, a guest post by UIUC and Bridgewater researchers, folds expert judgment into every part of RLVR.
Anthropic opened a research preview of the Model Hardware Standard (MHS), a shared spec letting AI agents operate microscopes, liquid handlers, and robotic arms in parallel. It cuts hardware integration from weeks or months to hours or minutes, and began as a collaboration with HHMI Janelia Research Campus.
Anthropic released its claude-protein-binder-design dataset on Hugging Face, containing 1,440 AI-designed miniprotein binders tested against 16 targets, with wet-lab results from two independent labs. Claude achieved a 27% hit rate in autonomous protein binder design, roughly twice the typical 10–15% rate.
