Google gave Gemini the ability to decide what part of a video to watch. Up to 88 percent fewer tokens and 66 percent lower cost is the pitch; the real shift is video stopping being a fixed-rate stream.
NVIDIA and CrowdStrike put red and blue agents in a closed loop and found the open-model pipeline produced fewer detections than the frontier system — but the only ones that held up.
OpenAI says frontier firms now generate 8.3 times as many output tokens per active user as typical firms, up from 2.6 times in January. That gap is the argument; three startups are the evidence.
OpenAI is wiring ChatGPT Health into Epic, which holds records for more than 325 million patients. The access is read-only. The liability is not.

Fambot wants to be the family inbox: email, calendar, and WhatsApp into a daily checklist. The pitch is time with kids. The product is another agent with a $3.5 million pre-seed.

A vendor case study with a useful admission buried in it: Gilbert + Tobin got 87 percent active usage by refusing to set usage targets and sending trainers into individual team meetings.
Apple's trade-secret fight with OpenAI is widening from employee access to alleged evidence destruction, putting offboarding controls and discovery under scrutiny.
