Today: China drops a new AI model that's rattling American tech companies, a young chip company might be worth $20 billion, and a Senate vote on AI in Medicare gets interesting. Let's get into it!

China's Kimi K3 Shakes Things Up

Beijing startup Moonshot AI released Kimi K3, a model now competitive with the best from Anthropic and OpenAI. Here's the twist: Moonshot plans to release the full model weights by July 27th, making it the largest open-source AI model ever released. That means any developer anywhere can download it, change it, and build on it for free. Frontier-level AI is no longer locked behind a handful of American companies, and that could mean better, cheaper tools for everyone.

A Chip Startup Worth $20 Billion

AI chip startup Etched is reportedly in talks to raise money at a $20 billion valuation, four times its previous value. Founded just three years ago by Harvard dropouts, Etched builds special chips for running AI after it's trained, and has reportedly hit $1 billion in chip order demand, positioning it as a real challenger to Nvidia.

Is AI Investment Slowing Down?

Money going into new AI companies dropped by about half in the second quarter, but that's more of a shift than a retreat: bigger AI companies are moving toward selling shares on public markets instead of just taking investor money. Global startup investment overall still hit a record $510 billion in the first half of the year. Meanwhile, the Bank for International Settlements warned that AI investment levels might be one-and-a-half times higher than what's actually efficient, adding real risk if productivity gains don't catch up.

The AI Battle Inside Medicare

The Senate voted on whether to shut down a Medicare pilot that uses AI to approve or deny patient care requests. The vote failed along party lines, 46 to 50, so the program continues. A new report describes a "bot versus bot" dynamic: insurance companies use AI to deny claims, and healthcare providers use their own AI to automatically appeal those denials. Both sides spend more on AI, and the costs get passed on to patients.

Some Genuinely Good Health News

Researchers at Oxford ran the first real-world trial of an AI tool that creates contrast-quality heart MRI images without injecting a contrast agent first. For two-thirds of patients, the AI-enhanced images worked just as well as traditional scans, meaning shorter, safer, cheaper scans for a lot of people.

The Big Wrap-Up

China's Kimi K3 model is rattling American tech companies, especially since it will be free to use. A three-year-old chip startup might be worth $20 billion. AI investment money is shifting, not disappearing. A Senate vote to stop AI in Medicare failed. And Oxford scientists found a way to make heart scans easier using AI.
