Microsoft Research’s AI Frontiers group ends after its team’s move to Microsoft AI

A founding AI Frontiers leader says the roughly 50-person Microsoft Research group was reorganized into Microsoft AI in early September, where its research-focused approach clashed with leadership’s emphasis on scaling. The leader and other founding members left; the group will not host interns in the coming year.

The account highlights a practical trade-off for AI organizations: scaling efforts may offer more predictable returns, while research can potentially reduce the compute needed for a given capability. The author cites experiments suggesting a Full Bandwidth Transformer variant could match a model twice its size, but provides no details here to assess that result or its real-world costs.
