Opensource

The FT just published an investigation into a tool called Heretic. It’s free, sits on GitHub, requires no specialist hardware, and strips the safety guardrails off open-weight AI models in under ten minutes. Since its release late last year, it has been used to produce more than 3,500 decensored models, downloaded over 13 million times. The creator stripped safeguards from Google’s Gemma 4 within 90 minutes of its release. ...

Nvidia announced the Isaac GR00T Reference Humanoid Robot at GTC Taipei. It’s an open hardware and software stack for academic research, built around the Unitree H2 Plus chassis, dual Sharpa Wave tactile hands, multi-view sensing, and a Jetson AGX Thor T5000 onboard. The software side is the full Isaac suite: Teleop for data capture, Sim and Lab for training, open foundation models, ROS middleware, and on-device inference via Jetson Thor. Partner institutions include Ai2, ETH Zurich, Stanford Robotics Center, and UC San Diego. Available late 2026 from Unitree. ...

Moonshot AI just open-sourced K2.6, and the benchmarks are hard to ignore. It beats or matches GPT-5.4, Opus 4.6, and Gemini 3.1 Pro on Humanity’s Last Exam with tools and SWE-Bench Pro, which are two of the more credible tests for reasoning and coding. It can run for 12 hours straight across 4,000 tool calls. One internal agent apparently ran autonomously for five days. And it can spin up 300 parallel sub-agents at the same time. ...
