Claims
- SK Hynix warned that AI memory shortages could peak in 2027 and persist through 2030, threatening the hardware supply chain underpinning AI expansion.
- Microsoft is routing some Excel and Outlook prompts to internal models to reduce inference costs and reliance on OpenAI and Anthropic.
- GPT-5.6 became the preferred model in Microsoft 365 Copilot, showing simultaneous pressure toward both cost savings and quality depending on the workload.
- OpenAI's head of safety is leaving as the company further integrates its safety and research teams.
- The next competitive advantage in AI will belong to teams that know when to use expensive models, cheaper models, or wait for supply constraints to ease—not simply those with the best model.
Key quotes
The useful AI winners may not be the teams that always pick the smartest model. They will be the teams that know when to spend, when to route, when to delegate, and when the real blocker is a chip factory, not a prompt.
The future still looks automated. It also looks very dependent on procurement.
Delegation is not a productivity hack unless someone owns the failure mode.
