mimalloc: A new, high-performance, scalable memory allocator for the modern era 

May 13, 2026 | Daan Leijen
mimalloc is an open-source, modern, scalable memory allocator that is a drop-in replacement for malloc and free. It is relatively small (~12K lines), with clear internal data structures, and is easy to build and integrate into other projects. It provides bounded worst-case allocation times (up…

    AutoAdapt: Automated domain adaptation for large language models 

    April 22, 2026

    Deploying large language models (LLMs) in real-world, high-stakes settings is harder than it should be. In high-stakes settings like law, medicine, and cloud incident response, performance and reliability can quickly break down because adapting models to domain-specific requirements is a slow and manual process that…

    ADeLe: Predicting and explaining AI performance across tasks 

    April 1, 2026 | Lexin Zhou and Xing Xie

    AI benchmarks report how large language models (LLMs) perform on specific tasks but provide little insight into their underlying capabilities that drive their performance. They do not explain failures or reliably predict outcomes on new tasks. To address this, Microsoft researchers in collaboration with Princeton…
