Does Reddit have an astroturfing problem? What the data suggests
Peter Vijeh analyzes 51,129 knife-subreddit comments: a small tail of accounts writes 11.3% of buying-thread brand mentions versus ~7.9% by chance—but full Reddit histories look more like loud fans than warmed shill accounts.

Mathematicians Build Long-Awaited Graph SandwichThe proof of a decades-old conjecture has given researchers a new way to understand complex networks.
Paulina Rowińska explains how Behague, Iľkovič, and Montgomery completed Kim and Vu's sandwich conjecture, letting hard properties of random regular graphs follow from easier binomial-graph results.

The Right Answer Is Not a Proof: Put Verification Inside the Reasoning Loop
Cognaptus explains PRoSFI: a 7B model emits small machine-checkable reasoning steps that Lean/Z3 can verify, raising measured soundness far more than final-answer accuracy alone on ProverQA-Hard.

An Empirical Study of Harness Design for Coding Agents
Fan et al. ablate planning, action space, and context management in a fixed coding-agent loop across 176 SWE-Bench/Terminal-Bench settings, finding when context management, planning, and predefined tools help—and when bash-only is enough.

Breaking the 1.58-bit Barrier for Ternary LLMs
Breaking the 1.58-bit Barrier for Ternary LLMs Abstract Ternary Large Language Models (LLM) store every weight as one of three symbols , so the cost of a ternary model is conventionally referenced to the information-theoretic bits per weight. The prevailing deployment format…

Training a 4B model to produce 81% faster query plans than Postgres
Leis et al. asked this exact question in 2015. Then, they asked it again 10 years later. Despite an enormous body of research spanning a decade since their original exploration, they found that query optimizers continue to leave much to be desired. I was surprised when I first learned about this. A Postgres database should know everything about the stuff that lives in its tables, no? How hard can it be?
