I was digging into Microsoft 365 Copilot updates today and stumbled on something they just quietly rolled out called Critique . It’s a new deep‑research system that doesn’t rely on a single AI model – instead, it uses a combination of GPT‑5.4 and Claude Opus together. Here’s how it works: One model generates potential answers. Another model evaluates them for accuracy. The best result gets returned. It’s basically a “checks and balances” system built into Copilot’s Researcher feature. Microsoft says it outperforms any single‑model approach – and it’s already live for existing Copilot users at no extra cost. submitted by /u/Remarkable-Dark2840
