Firm-owned post-trained models

Firms post-train and keep their own models on their own data instead of renting a general frontier model, often while still renting the compute.

Evidence as of October 2026

By Thinking Machines' account (15 Oct 2026), Bridgewater's text-to-SQL model built on Tinker beat named frontier models at 15% of their cost; YC's Winter 2027 'Own Your Intelligence' request backs the same shift.
