What Makes Inference Nondeterministic? (12 minute read)
When the same prompt is sent to an AI model multiple times at zero temperature, variations in the results can occur due to the nondeterministic nature of floating-point arithmetic combined with server load dynamics. The model's output can differ based on how requests are batched and how the GPU processes the addition of numbers, leading to discrepancies despite identical settings.

.gitignore everything by default (3 minute read)
Instead of allowing all files by default and selectively ignoring certain ones, a new approach suggests ignoring everything by default and only allowing specific files to be tracked by Git, which can prevent accidental commits of unwanted local files.

OpenAI's Agents Claim a Navier-Stokes Breakthrough (8 minute read)
OpenAI published a claimed solution to the Navier-Stokes existence and smoothness problem, produced by a system of roughly 10,000 agents and accompanied by a Lean-formalized proof. The company says the effort used about 130 billion output tokens, with GPT-6 Astra handling the final formalization and verification.

Pretraining Progress Is Mostly Coming From Data (18 minute read)
A controlled study of open model recipes and datasets from 2019 to 2025 found that data improvements produced a 12x compute-efficiency gain at a 10^19 FLOPs budget, versus 3.7x from model improvements. The authors stress that the experiment covers small models and pretraining only, while architecture work still makes larger-scale training possible.

I Asked 100 Agents to Hack Me (10 minute read)
Shrivu Shankar gave roughly 100 self-hosted, guardrail-removed agents five hours to compromise his online accounts, and they broke into five lower-tier accounts through old software flaws and password attacks, attempted social engineering 16 times, and assembled sensitive personal data for about $210 in GPU time.
