How Anthropic's Claude Code team reviews AI code
In Anthropic's monorepo daily landed changes went from ~2,500 (May) to 30,000+ (Sept). The Claude Code team has Claude review every PR before a human, scales human approval by risk (0/1/2 people, classifier-set, agent approvals never count), and reports merged PRs more than doubled Jun->Sep while the revert share fell 40%+. A concrete template for review when agents write the code.

Stanford's NCM writes text coarse to fine
Instead of one token at a time, Stanford Hazy Research's Next-Concept Modeling generates a hierarchy of codes level by level, predicting every code in a level in parallel. Against the strongest diffusion LMs at matched size on one H100: 21x faster on LM1B with better quality, 10x on OpenWebText at comparable quality, and the same ROUGE-L on XSum at 31x faster; 86.1% vs 81.3% on hard Sudoku; about 4-5x fewer training tokens. Early research: ~100M-parameter models, scaling tested to 725M.

AstraZeneca's AI drug discovery deal with insitro
AstraZeneca pays insitro $40M upfront, with up to ~$1.46B in potential milestones plus single-digit royalties, to apply insitro's Virtual Human AI platform to MASH (a metabolic liver disease) and cardiomyopathies, where one diagnosis spans patients with different underlying biology. insitro takes AstraZeneca-nominated targets to development candidate; AstraZeneca leads trials and commercialization with exclusive worldwide rights to selected programs. Fine print: under 3% of the ~$1.5B headline is upfront, and the work starts at target discovery.

Colossal's GenoMorph AI shortlists dodo beak DNA switches
With only one high-quality dodo genome (vs 104 for the woolly mammoth), Colossal Biosciences' GenoMorph learns from living birds instead: an embryo atlas of chicken, quail, duck and pigeon samples plus genomes and CT skull measurements from 70+ species. It flagged ~2,300 candidate regulatory DNA switches (653 linked to beak size, 1,698 to beak thickness and breadth). Fine print: Colossal says these are not yet shown to cause those traits; they are a prioritized shortlist now entering lab tests, with the strongest being engineered into Nicobar pigeon germ cells. No date for a living dodo.
