Nine picks, hype filtered out. The theme: the giants are buying the open bits, AI is reaching into records and factories, and the boring milestones (yields, error rates) are the ones that matter.
1. Nvidia is buying Hugging Face for $12.9bn. The chip giant is acquiring the biggest open-source AI hub. Great for Nvidia's grip on developers, unnerving for anyone who valued the hub's neutrality.

2. OpenAI plugged ChatGPT into the records of 325 million patients. ChatGPT Health is now connected to Epic. Huge upside for understanding your own care, and enormous privacy questions.

3. Anthropic built an AI that does AI safety research, and it beat some humans. Its Automated Alignment Researchers propose and test safety fixes. Genuinely hopeful, and a little vertiginous.

4. Stocks bounced as bond yields cooled. A calmer Fed comment eased the pressure, and Snowflake (+20%) and Dell (+16%) posted blowouts. Broadcom beat and fell anyway. (Not investment advice.)

5. IonQ and Nvidia cut quantum error rates by 54%. Aimed at drug discovery, with IonQ and QC Ware hitting chemical accuracy. The unglamorous kind of quantum progress that actually counts. (Not investment advice.)

6. Suno put download limits on the music you make. From 3 September, the top AI music tool caps exports, and power users are furious. The licensed era of AI music keeps adding strings.

7. Meta is rolling out an internal AI agent called Hatch to everyone. Big-company agent rollouts are the real preview of enterprise AI, and this one is worth watching more than the headlines.

8. IBM's 4,158-qubit machine is chasing the milestone that matters. Kookaburra targets a first useful quantum advantage by year-end. Bigger news than any qubit count, if it lands. (Not investment advice.)

9. Anthropic's new enterprise feature lets companies keep the keys to their own AI logs. Zero data retention plus customer-held monitoring logs. Dry, and exactly what unblocks AI in big, cautious organisations.
