John Langford writes "The End of AI Frontiers," memorializing the shutdown of the 50-person MSR sub-organization he co-founded after ChatGPT to make research more organized.
- Founded in 2023 because lone-researcher efforts inside MSR arrived late with weak baselines
- Outputs included the Autogen agent orchestration framework, the Fara computer-use agent, plus fundamental work: the Next Latent objective for extrapolation, Dion3 (an improved Muon), and the Full Bandwidth Transformer using recursion
- AIF shared code by default with all of Microsoft via a monorepo
- He cites disagreements and compute as a persistent bottleneck, calling it a painful train wreck
The post signals shifting research priorities inside Microsoft.
