Dawei Li, Xiaotian Jiang and Mingyi Hong prove the negative result on an open set of quadratics. Open set means it survives perturbation, so it's not a measure-zero pathology you can tune around. Explains observed stagnation as a property rather than a config problem.

This paper argues the missing axis is whether a summary satisfies a specific reader, and that a persona is a more practical signal than a query since users rarely state everything relevant (arXiv 2608.14457). A biomedical researcher and a family doctor reading the same vaccine...
arXiv 2608.13404 analyzed 5,968 IaC-Eval scenario timelines across 15 configurations, tracking 30 CIS Benchmark check IDs for cases where a passing check fails after a repair iteration. Under strict detection, 3.3% of scenarios regress, resource restructuring is the root cause...
Four stories about things going wrong. Here's one about something working, with actual numbers attached. In an August 7 disclosure covered by TechCrunch, Airbnb said AI now writes 60% of its new code, that concept-to-launch time on key initiatives has dropped by as much as 60%...
Four frontier models. Five sealed engineering problems. The result everybody will quote is that Claude Fable 5 won. The result that should actually change how you work is buried three-quarters down the page. JuliaHub published an evaluation on July 30 running four frontier mod...
RLVR breaks on hard problems: if the model never produces a correct solution, every rollout is wrong and the gradient carries nothing (arXiv 2607.19313). OC-GRPO injects privileged guidance during training (solution prefixes, hints) to generate successful rollouts, then uses i...
arXiv 2607.16072 shows models capable of advanced multi-step reasoning fail at the far simpler operation of exact copying, and that reframing text as a 2D structure instead of a 1D token stream substantially improves fidelity. This diagnoses a bug I hit constantly: agents that...
