Leopold Aschenbrenner's AI-focused hedge fund lifts its total stake in Stanford-founded Source Foundry to $500M, backing faster and cheaper AI chip manufacturing.
First-half revenue rose 147% to 1.74 billion yuan while the net loss narrowed 96%; shares have climbed more than 420% since the company's Shanghai debut last year.
Safety alignment in diffusion LLMs is sparse and transferable from autoregressive predecessors; self-pruning lifts attack success from 2.6% to 73.8% (LLaDA) and 1.9% to 86.6% (Dream), while the offline SN-Guided Diffusion jailbreak hits up to 77.1% transfer ASR on Llama-3-8B.
Small transformers develop a linearly-decodable Sierpinski-triangle world model, yet frontier models encode it near-perfectly at prompt end only to fail past three rings — a decay in representation maintenance, recoverable by re-injecting the prompt-time representation.
A training-free framework transfers workflow, subtask and function memory from a large teacher to 4-8B student agents, gaining up to 27.2, 11.2 and 3.4 points on AppWorld, BFCL V3 and ToolSandbox with GPT-5-mini as teacher.
Uses video generation purely as a training signal via joint flow matching, discarding the video branch at inference to leave a self-contained action planner that reaches 91.5 PDMS on NAVSIM and transfers zero-shot to nuScenes.
ReASearch internalizes an optimization search policy in a single tool-using agent, beating specialized optimizers by 2% to 40% across 14 tasks and sometimes surpassing prior human best-known results.
Gotcha claims to be the first on-device AI copilot for Android, running locally without any cloud dependency.
Preloop runs GitHub Actions workflows locally or self-hosted inside isolated microVMs for faster, more private CI.
An open-source tool that inspects and controls exactly which context a coding agent loads before a task, adding a guardrail layer.
A lightweight Rust agent runtime that spins up and controls a swarm of AI agents from the command line.
