AI & Tech briefing · Friday, 31 July 2026

This period is marked by three competing currents in AI: frontier model advances that deliver better performance per dollar, real-world breaches that expose how far sandboxing still has to go, and the growing operational challenge of securing AI agents in production. For builders, the message is clear: model efficiency gains are real and substantial, but the security fundamentals remain fragile. The infrastructure arms race continues.
