03DEEP DIVES & ANALYSIS

BRAIN THE SIZE OF A PLANET: ARE LLMS THONKING TOO HARD?

Earlier studies showed that Opus 4.6, GPT 5.4, Gemini 3.1-pro-preview, Deepseek R1-0528, and Qwen 3.6-plus were unable to find two of the vulnerabilities discussed in the Mythos blog post without extremely revealing hints. This study continues the previous experiments with 26 distinct Claude-4.6/4.7 and GPT-5.4/5.5 combinations and different context window sizes and reasoning efforts. It found that higher reasoning effort, and even later models, are not always better for triaging security results.

BUILDING AI AGENTS FOR AR GLASSES AND XR DEVICES WITH NVIDIA XR AI

Nvidia XR AI provides a reusable foundation for connecting extended reality devices to GPU-accelerated AI services running in the cloud, data center, workstation, or edge. It gives developers access to an open source library for building intelligent agents for AI glasses, AR glasses, and XR headsets. These agents will be able to see what users see, understand token or typed intent, call enterprise tools, and respond within the same XR session. XR AI is now available in public beta.
