Palantir just presented evidence that a much smaller one can beat them at a specific job, and do it for less money.\n\nThe company reported that a fine-tuned, 4-billion-parameter [Nvidia](https://cryptobriefing.com/markets/nvidia/) model outperformed larger models on a task built by McCarthy Building Companies, at a lower cost.\n\n## A small model with a very specific education\n\nThe model in question is Nvidia’s Nemotron 3 [Nano](https://cryptobriefing.com/markets/nano/) 4B. McCarthy, a construction firm, fine-tuned it on more than 100,000 labeled requests-for-information, or RFIs.\n\nFor the non-builders in the room, an RFI is the formal question a contractor sends when plans, specs, or site conditions don’t line up. They are the paper trail of everything that could go sideways on a job site.\n\nThat makes them a goldmine for spotting trouble early. McCarthy used the trained model to classify potential project risks and predict how those risks might hit schedules and budgets.\n\nAccording to the findings, the tuned model delivered superior performance on that classification work. It also ran at markedly lower operational cost than its larger counterparts.\n\nMcCarthy is also using AI in a separate subcontractor contract-drafting workflow. That workflow is expected to save approximately 30,000 work hours annually.\n\nThat is a projection, not a banked result.\n\n## The rest of the Sovereignty Bootcamp lineup\n\nThe McCarthy results were presented at Palantir’s Sovereignty Bootcamp on October 21, 2026. The event focused on what Palantir calls sovereign AI deployments across multiple sectors.\n\n### AI, tech, and the markets they move—in one daily briefing.\n\nDaily. Free. Join 34,000+ readers across crypto, finance, and policy.\n\nThe idea behind “sovereign” AI is control. Customers fine-tune models on their own data, inside their own environment, and keep ownership of both the data and the resulting model.\n\nDefense contractor L3Harris was one of the featured customers. The company reported that early tests produced cost reductions of 95%.\n\nThat figure comes from early testing, so it deserves some patience before anyone treats it as a steady-state number.\n\nTampa General Hospital also shared results. After fine-tuning the Nemotron model to match its own privacy and risk standards, the hospital saw a 22-fold reduction in AI latency.\n\nIt also reported a 7% improvement in classification performance.\n\nThe three examples span construction, defense, and healthcare. Those are industries with strict data rules, high stakes for errors, and little appetite for shipping sensitive records to a third-party model.\n\n## Background: Palantir and Nvidia’s bet on smaller, owned models\n\nThe bootcamp built on partnerships between Palantir and Nvidia launched earlier in the year. The pitch pairs Nvidia’s compact Nemotron models with Palantir’s software for deploying AI on proprietary data.\n\nThe broader thesis is that task-specific results come from combining a company’s own data with a smaller, specialized model.\n\n## What this means for enterprise AI buyers\n\nThe results also highlight where the real advantage sits: in the data. McCarthy’s edge came from more than 100,000 labeled RFIs that no competitor or general-purpose model provider has access to.\n\nThere are caveats worth watching. The headline numbers come from customer-reported results, and some, like L3Harris’s 95% figure, are tied to early tests.\n\nMcCarthy’s 30,000-hour figure is also an expectation rather than a measured outcome.\n\n**Disclosure:** This article was edited by Diego Almada Lopez.
