MIT CSAIL showed an AI editing a small model's weights and lifting its MATH-500 score from 7.9% to 48.1%. We checked the released records: the gains hold up, the edit rebuilds exactly, some failures remain, and telling models apart is not yet explaining them.
OpenAI now runs activation probes on every GPT-5.6 completion. What their post says they do, credit for publishing it, and the questions a fair outside check would ask: selection and seeds, drift, shortcuts, harmless look-alikes and numbers tied to runs.
Nikita Pavlichenko tested LLM design changes since GPT-3 under one budget, stacked the winners, and listed his limits first. What a fair comparison looks like, and what it changes for our own work.
HLE batch 2 passed, and its grouped test only just did. What we fixed in advance, why batch 1 was voided rather than fixed, and what the result can't tell you.
How our receipt log works in plain words: signed checkpoints, an append-only log, Rekor anchoring and two outside witnesses. With commands to check it yourself in a few minutes.
An unexpected attachment led to a practical question: who can authorize an agent to act? A morning investigating prompt injection, permissions and exact-action approval.
