AI Round-up: June 3, 2026

OpenAI led the snapshot by pushing Codex further beyond coding: Sites turns work, ideas and plans into shareable apps, role-specific plugins give Codex specialist workflows across sales, data, creative and product work, and an official article framed Codex as a productivity tool for knowledge work. That thread carried through OpenAI's YouTube demo and Reddit questions about Copilot Pro+, OpenClaw compatibility and guardrails around coding agents.

Microsoft answered with its own agent stack, led by Scout as an always-on personal agent, Work IQ, Frontier Tuning and fresh GitHub agentic-development controls. Anthropic expanded Project Glasswing and Claude Mythos access to more partners, while Perplexity previewed hybrid agentic inference, Google DeepMind promoted Co-Scientist, and security stories covered Red Hat npm credential theft, Codex supply-chain risk and AI safety litigation.
