AI & Agent Development

OpenAI has mandated hardware-backed passkeys for its Trusted Access Cyber members to enhance login security mandates passkeys. In a related development, analysts suggest OpenAI's advertising business is significantly underperforming, potentially missing its forecast by 90% misses forecast. Meanwhile, a study explores Microsoft's early 2026 rollout of Claude Code and GitHub Copilot CLI studies Copilot. Researchers have also developed a method to flag AI models trained on child abuse imagery without generating the content itself flags models. A new platform called Plan Wright aims to provide a control plane for AI coding agents, allowing for planning in Claude Desktop, implementation in Codex, and review by a custom triage agent controls agents. Show HN: Sx 2.0 offers a way to share AI skills within a team via a Dropbox folder shares skills, and Context Vault provides a shared memory layer for AI tools and teams. Another Show HN introduces Nobie, an Excel-compatible runtime for agents and humans Excel runtime. Jacquard, a new programming language, is designed for AI-written, human-reviewed code new language.

Machine Learning & Data Infrastructure

Tensor operations are highlighted as a core component in machine learning performance tensor is might. Efforts are underway to make LFortran differentiable with LFortran and Enzyme, enabling automatic differentiation for Fortran code. For those looking to run CUDA on non-Nvidia hardware, Spectral Compute is aiming to offer an alternative run CUDA. Show HN: Mem Stitch offers a zero-copy context bridging solution for vLLM, claiming a 25x speedup in time-to-first-byte. You Track DB has been introduced as a general-use object-oriented graph database.
