The Gigawatt Threshold

Two American AI campuses already pull more power than San Diego. The next six months decide whether that power turns into a new kind of machine, or just a bigger version of the one we have.

Looped Transformers: Depth Without New Parameters

A working note on looped transformers: reuse one layer stack across passes to buy effective depth. Nanbeige4.2-3B is the latest compact example, with author-reported agent scores that beat much larger models.

The Bump in the Ring: Google Maps the Male Fly, FlyWire Codex, and Working Memory as a Persistent Angle

Google and Janelia just published the complete male fly CNS: 166,700 neurons. FlyWire Codex already indexed the 2024 female map. The interesting part is not the count. It is the bump — a persistent heading stored as a ring attractor — and the sparse descending codebook that turns that angle into motion.

KAT-Coder-V2.5: Infrastructure Beats Scale for Agentic Coding

KwaiKAT’s KAT-Coder-V2.5 comes within a few points of Opus 4.8 on repository SWE, tops PinchBench, and the open KAT-Coder-V2.5-Dev (35B MoE / 3B active) leads same-scale peers. The paper’s real story is environments, trajectories, and harness-aware RL—not parameter count.

Mage-Flow: Open Image Generation and Editing from Microsoft Research

Microsoft Research open-sourced Mage-Flow, a compact 4B stack for text-to-image and instruction editing. I ran the full family locally, and a hard, structured prompt produced this wizard key art—proof that open image models are getting seriously good.
