[AI DAILY NEWS RUNDOWN]

Top U.S. banks found AI agents logging into customer accounts with borrowed passwords, and are cutting them back to read-only. Plus: Walmart and Claude Duet set rules for agents that spend, Gartner's AI value gap and Microsoft's AI out-diagnoses doctors.

The other side of the door: Walmart's Agent Gateway and spending limits, Anthropic's Claude Duet asks before it pays, and 1Password for Agents.
Who watches the agents: auditors found about 10% of OpenAI's internal coding-agent traffic unmonitored for months.
The AI value gap: Gartner says only 13% of CIOs see significant value; Andrew Ng's four levers.
AI meets patients and teens: Microsoft's MAI-DxO in Science, and a failing grade for ChatGPT for Teens.
The money: Meta's new Muse models and $25B verdict, OpenAI's reported $30B round, DeepSeek's reported $15B.
