Ai2 open-sources AstaBrief 8B scientific report-generation model
Ai2 released AstaBrief 8B, an open-weights model that turns a research question and retrieved literature excerpts into a cited report. It powers Fast mode in Asta's Generate a report feature alongside Claude-based Thinking mode. Ai2 reports Fast mode averages 51.1 seconds per report versus 178.5 seconds for Thinking mode, about 3.5× faster, and is releasing the training data.

Ai2 replaces priority GPU scheduler with budget-based fair-share system
Ai2's AI Infrastructure team replaced its priority-based GPU scheduler with a system using GPU time budgets, hierarchical fair-share allocation, and time-slicing contracts. The institute manages thousands of NVIDIA H100, B200, and B300 GPUs across 88- to 1024-GPU clusters for about 150 researchers, with demand running 2-3x available capacity. The change moved GPU allocation debates into a transparent administrative budgeting process.
