1. Nvidia’s free model labels who is talking
Nvidia released Nemotron 3 Diarization, a 100M-parameter model that marks who is speaking, up to eight voices, and the weights are free to download. It leads Voice Arena’s diarization benchmark at a 14.72% error rate, against 19.3% for the runner-up. Accuracy drops with background noise and reverb.

2. AI users almost never say they do not know
Across five experiments, people withheld judgment on 3 to 6% of trivia questions when they had a chatbot, and 36 to 44% when they did not. Their answers were right 9.2% of the time with AI, against 27.5% without it, while their confidence rose. The work is a preprint covering 3,132 people on film trivia.

3. Insurers blame AI for $942M in extra bills
The Blue Cross Blue Shield Association says hospital AI coding tools pushed more stays into higher-paying categories, adding $942 million to its plans’ costs over two years. Stays billed as medically complex rose from 37% of claims in early 2023 to 40% by the end of 2025. The analysis is the insurers’ own.

4. US and China agree on an AI incident line
A White House fact sheet says the two governments have set up a US-China Super Intelligence Dialogue, with the next exchange by November 2026, plus a bilateral communication channel for AI incidents. Both sides also agreed to call the technology super intelligence. Neither has said what counts as an incident or how the channel will work.

5. DeepSeek runs 3 million sandboxes a day
A DeepSeek paper describes DSec, the platform that runs the environments its agents train in. A production unit spans roughly 160 nodes and supports about 3 million sandboxes a day, more than 380,000 at once, and more than 5,000 created a second. The numbers are DeepSeek’s own.
