Why Big Tech Is Racing to Build In-House AI Training Platforms

Big Tech companies are increasingly building their own AI training platforms rather than relying on third-party tools. In this episode, Lucas and Luna explore why Meta, Google, and Amazon are investing heavily in proprietary infrastructure for fine-tuning and deploying models. They break down the economics: from the cost of GPU clusters to the strategic advantage of owning the full stack. With Alphabet down 6.4% over the past five days and Meta falling 5.5%, the hosts ask whether the market is pricing in the expense of this AI arms race. They also discuss how smaller players like Synthesia are innovating beyond video generation into live coaching, and what that means for the platform wars. Specific examples include Meta's custom training framework and Amazon's new "Trainium" chips. The episode also touches on the talent war for AI engineers and why owning training infrastructure could be the next big moat.
