OpenAI co-founder's 3-year secret model Jev overtaken by an open-source clone in 3 days
gaganghotra_ · x · 2026-09-19
A viral post claims an OpenAI co-founder spent three years quietly building the model Jev, only for the open-source community to ship a better-performing open clone (Laya) in just three days.
The author's takeaway: with open-source closing gaps at a days-long cadence, starting an AI company right now 'carries way too much risk' — closed development is losing its moat.
