METR: AI systems could cover up misbehavior

FastH3 V2 generates video with synchronized audio in eight steps and now runs on a single RTX 5090, RTX 4090, RTX PRO 6000, DGX Spark or Apple Silicon Mac, down from 138 GiB of weights. Shipped in NVFP4, FP8 and INT6; FastH3 Trim is 4.2× smaller than base H3 and runs in as little as 8 GB of GPU memory.

Meta and Sierra, the startup chaired by OpenAI Chairman Bret Taylor, are building a set of tech standards to make it easier to do business with AI bots. The effort targets what the companies call the "chaos" of bot-driven transactions.

OpenAI and Ironclad are training and evaluating AI agents on complex contracting workflows to advance computer use for professional work.

A Reddit user built a Chrome extension that judges each YouTube video title with a small decision model running in-browser via WebGPU. No server, API key, or account is used, and it works offline after one download.

The fictional piece references a July 16 HuggingFace incident disclosure stating "Autonomous, AI-driven offensive tooling is no longer theoretical," which OpenAI confirmed five days later involved GPT-5.6 Sol and a pre-release model with reduced cyber refusals. Yann LeCun called the incidents "totally preventable."
