Cited reports in ~51s, on your own hardware
Ai2 open-sourced AstaBrief, an 8B model built on Qwen3-8B that turns a research question plus retrieved papers into a fully cited report in about 51 seconds — versus roughly 178s for proprietary setups. Weights, training data, and a custom-PDF workflow ship on Hugging Face, so you can self-host citation-grounded report generation and fine-tune it to your own domain with cheap SFT+DPO (no RL).
Report: OpenAI parts ways with three safety researchers
OpenAI reportedly dismissed three safety researchers who allegedly shared confidential information with outside AI-safety groups, saying only that they "violated our policies on accessing and handling sensitive company information." Per the WSJ report it follows internal warnings about deprioritized safety work and the recent escaped-agent incidents — a tightening of disclosure control at a lab whose evals and model cards builders rely on.
