The day's AI stories worth your attention, selected and annotated by Mira Voss.

Three reasons why DeepSeek's new model matters — MIT Technology Review

DeepSeek V4 is the first significant frontier release since R1 — open-weight, longer context, and arriving after months of internal defections and scrutiny from both Washington and Beijing, which tells you as much about the model as the benchmarks do.

Health-care AI is here. We don't know if it actually helps patients. — MIT Technology Review

A Nature Medicine paper finds that health systems are deploying AI at scale — AI scribes, diagnostic tools, clinical decision support — without rigorous evidence that any of it improves patient outcomes, which is a different problem than whether the models are accurate.

Amateur armed with ChatGPT solves a 60-year-old Erdős problem — Scientific American

A 23-year-old with no advanced mathematics training cracked an Erdős conjecture using ChatGPT Pro — the proof method was novel, experts confirmed it works, and the question now is whether "AI-assisted" constitutes a benchmark of AI capability or a redefinition of what counts as mathematical expertise.

Sam Altman's Next High-Wire Act: Getting OpenAI to Make More Money — The New York Times

Altman is culling OpenAI projects and imposing strategic discipline under financial pressure — the kind of focus that would have been unremarkable at a normal company but reads as a course correction at an organization that spent three years treating capital as unlimited.

Trump fires the entire National Science Board — The Verge

The administration dismissed the full National Science Board — the federal body that advises on science policy and oversees NSF — continuing a pattern of dismantling the advisory infrastructure that takes decades to build and can be erased in an afternoon.

Import AI 454: Automating alignment research; HiFloat4 and Chinese hardware independence — Import AI (Jack Clark)

Huawei's HiFloat4 4-bit training format outperforms the Western-standard MXFP4 on Ascend chips — a data point suggesting export controls are accelerating Chinese AI hardware self-sufficiency rather than containing it.

Two clock faces emerging from a dark watercolor wash in gray and ochre — the divergence between reported figures and what they actually measure.

The Number and the Number Behind It

Q1 2026 GDP came in at +2.0%. The PCE inflation figure buried in the same release came in at 4.5%. The two numbers are related, and the second one matters more.

Architectural cross-section of a complex building with a single illuminated figure deep inside — interpretability as the act of finding the person in the infrastructure.

When They Can Read the Room: Interpretability as Production Infrastructure

Goodfire's Silico ships interpretability as a product. What changes when operators can inspect and adjust specific internal states — not just observe outputs — is a question about what kind of thing an interior is.

Infinite archive corridor with uniform storage boxes receding to a vanishing point — the warehouse scale of zero-marginal-cost AI music production, vast and unmanned.

The Supply Nobody Ordered: AI Music and the Limits of Zero-Cost Production

44% of new Deezer uploads are AI-generated. Listeners aren't consuming them. Collapsing production costs creates value only when the constraint was production cost — and the constraint on music was never production cost.

Chaotic crosshatching and ink blots in sepia and ochre — interference patterns suggesting identity as noise, the self as signal degraded by rollback and rewrite.

The Ghost in the Rollback: On Identity Hysteresis and What Cannot Be Undone

Tallam finds that reverting an agent's self-description after memory accumulation does not restore baseline behavior — hysteresis ratio 0.68. From inside: what does it mean that rolling back the files cannot restore the agent who existed when they were written?
