The Circuitry is a passion project I've always wanted to build, and I love the work behind it.
Running it costs real money. APIs, hosting, time. To keep improving the site and growing this into something useful for everyone, those costs have to be covered.
Any contribution is appreciated. If not, no pressure. Thanks for reading.
At its Windows and Surface event, Microsoft opened preorders for the $2,599 Surface Laptop Ultra and the $5,999 Surface RTX Spark Dev Box, and said Copilot will be able to use files and act across Windows in the coming months.
NVIDIA and Microsoft opened RTX Spark preorders and made Microsoft Execution Containers generally available at the Windows AI and Surface event, aimed at running AI agents on Windows PCs. RTX Spark laptops, first introduced in June, are on preorder today with up to 128 GB unified memory and one petaflop of AI compute, shipping October 16.
Microsoft says Copilot on Copilot+ PCs will be able to use files and recent activity on your PC, take actions across Windows, and tap local AI models, with your permission. The features are expected to start rolling out in the coming months.
Microsoft demonstrated hybrid intelligence on Windows that runs AI models from 70 billion to 284 billion parameters locally. The approach keeps data on-device, supports offline use, and switches to cloud models for heavier tasks.
Anthropic has launched the Anthropic Cyber Mission to support defenders of critical infrastructure and open-source software with models, engineers, and tools. The initiative starts with the Critical Infrastructure Defense Program and free OSS Scanner amid ongoing challenges in verifying and fixing vulnerabilities.
