Cartridges: Lightweight and general-purpose long context representations via self-study
Large language models are often used to answer queries grounded in large text corpora (e.g. codebases, legal documents, or chat histories) by placing the entire corpus in the context window and leveraging in-context learning (ICL). Although current models support contexts of 100K-1M tokens, this setup is costly to serve because the memory consumption of the KV cache scales with input length. We explore an alternative: training a smaller KV cache offline on each corpus. At inference time, we loa…

Eight Bitcoin Wallets Move 80,000 BTC in Largest Ever ‘Satoshi Era’ Transfers
All of these moved coins are among the rarest class of BTC: mined or transacted during the “Satoshi era,” a loosely defined period from bitcoin’s launch in 2009 through 2011, when its pseudonymous creator was still active online.

Causal Impacts of Protected Bike Lanes on Cycling Behavior with Demographic Disparities
Cities around the world face significant barriers to grow urban cycling, including competing budgetary priorities and car-centric streets. Thus, when making decisions regarding the installation of bicycle infrastructure, it is crucial to understand if and to what extent different bicycle-lane types increase bicycle ridership. However, associations between bicycle infrastructure and bicycle ridership have primarily been studied in the context of individual lanes and corridors, or when analyzed a…
