I make hard AI approachable.

Hi, I’m Stefan, Lead Developer Relations Engineer at Oumi! I did my doctorate at Oxford in Generative AI before it was cool, and have since gone on to six years as a machine-learning researcher at Meta and Twitter, and a developer advocate at Zilliz and Oumi.

A diagram from the Oumi product demo titled “Use inference intelligently”: every request from your AI app goes through a fine-tuned model router to small fine-tuned models of your own, at 11% of frontier token cost, with the feedback loop intact — A frame from the Oumi platform product demo.

Written without AI

Original writing and research that has reach: social media, front pages, national press.

Advocacy backed by working code
