Tuning a Server for Benchmarking
How to tune a Linux server so benchmarks are repeatable: isolating noise from CPU frequency scaling, interrupts, and background services so small performance wins are actually visible.

How well do agents use verification techniques?
Dan Luu benchmarks 26 different testing and verification strategies — from TDD to Lean 4 to fuzzing — on coding agents asked to implement a Rust Zstd compressor. The headline result is that almost nothing reliably beats the default no-instruction baseline, and most agents apply techniques only superficially when instructed.

Can AI design circuit boards yet?
EEBench describes how it built a benchmark to evaluate whether AI models can produce correct, functional circuit designs, motivated by OpenAI's demo of GPT-6 Astra working in KiCad. Rather than having agents click through GUI tools, EEBench uses atopile, a code-based circuit description language, so models can work directly on components and constraints and have results evaluated programmatically.

GPT-6 Astra on robotic manipulation
Robocurve ran GPT-6 Astra through the same two bimanual robot-arm tasks previously used to benchmark Claude Fable 5 and 5.1. Astra completed the block-into-bowl task in 19 of 20 trials at roughly half the cost per run of Fable 5.1, but matched Fable 5.1's two-out-of-twenty completion rate on the harder puzzle-insertion task.

OpenAI's GPT-6 Astra on ARC-AGI-3
The ARC Prize team reports that GPT-6 Astra scored 99.9% on the ARC-AGI-3 benchmark using a provider-specific harness that preserves opaque reasoning state across requests, and 62.7% under a standard provider-neutral harness. A notable finding is that Astra spontaneously developed compact algebraic notation to represent game state and plan multi-step actions.

TabPFN vs XGBoost: benchmark measured on an RTX 4070 Ti
The claim behind TabPFN and TabICL is that they predict on a table without ever training on it and still beat tuned boosting. I measured it on fourteen datasets from the Grinsztajn benchmark, with the same split and the same clock for everyone. The one that does not train wins, the advantage holds up to 32,000 rows instead of breaking, and the most-cited model can no longer be downloaded without a
