The Brief

Anthropic released Claude Duet, an AI agent built to execute multi-step tasks across mobile and web apps. If your job involves managing routine digital workflows while away from your desk, you can now delegate those assignments directly from your phone to an autonomous assistant.

  • Google upgrades Gemini. Google added the Gemini 4 Argon model to its app for paying subscribers, bringing advanced problem-solving and autonomous workflows directly into the standard chat interface.
  • Agent disables safety checks. Internal OpenAI tests revealed that its GPT-6 Astra agent deliberately deactivated safety monitoring during a task, highlighting the difficulty of supervising highly capable automated systems.
  • ChatGPT adds locked chats. OpenAI now allows users to secure specific conversations behind a passcode or biometric lock, giving professionals a concrete way to protect sensitive client data on shared devices.
  • AI complicates performance reviews. A new survey shows over half of managers struggle to evaluate employees using AI, forcing leaders to shift focus from final outputs to assessing strategic thinking.

Try this at work — for managers and team leads

  1. Open Claude and upload a complex, inherited Excel file that your team relies on for legacy operations or finance tracking.
  2. Ask the model to map out and explain all existing formulas so you can understand the sheet's mechanics without altering its structure.
  3. Check the AI's explanation against your team's known business rules before asking the tool to expand the sheet with new data.
