Not the usual model card drop — Anthropic says Claude agents mined phage DNA for odd reverse transcriptases and spotted an array-associated system (ART) with CRISPR-like repeats, with mostly high-level human direction. Feng Zhang called the RNA-repeat + RT pairing genuinely intriguing. Function still unknown, but the workflow (agent genome mining → lab follow-up → early preprint) is the singularity-adjacent part worth watching. Primary Anthropic writeup, not a screenshot.
