AI companies consider building their own models instead of renting

• Some AI companies are evaluating whether to develop internal models rather than rely on external APIs, particularly when cost, speed, data privacy, or competitive advantage matters.
• The decision framework involves testing performance through custom evaluations and customized training processes tailored to specific needs.
• Companies exploring this approach are considering systems that learn continuously from real-world usage rather than static models.

AI companies should selectively own intelligence when frontier APIs constrain cost, latency, proprietary data, or strategic control. The roadmap includes evals, custom harnesses, targeted post-training, and online learning loops.
