The author argues that the current trend of enterprises post-training open-source models on proprietary data often starts from the wrong place.

The Right Approach: Companies should first build robust evals to identify which models sit on the Pareto frontier of cost and performance for their specific use cases.
Strategic Motivations: The desire to own models usually stems from application-layer companies wanting to protect themselves from labs and control data. However, unless model capability is the core barrier to entry, this investment is rarely justified.
