## What technology stack does PNC run its AI on?

PNC is building its AI on infrastructure it owns. The 2026 proxy says head of technology Deborah Guild advanced a national data-center strategy, with a new Eastern facility under construction and a Midwestern hosting site secured; on October 15, 2026 Demchak said GPU chips are already in PNC's data centers and their cost shows up as rising depreciation. Underneath sit a data lake with 'one source of truth', digitized policies and procedures, and HR systems that recognize agents. Models are mixed by job: in September 2026 CFO Rob Reilly described a harness that picks the cheapest adequate model, frontier models reached through hyperscalers, open-weight models hosted in-house and proprietary small language models; head of data and automation Ned Carroll has said he is 'very bullish on small language models'. On top, Microsoft Copilot and AI-enabled search run for employees, about 115 orchestrated AI agents built the July 2026 PNC Mobile app on a patented data-streaming microservices architecture, and the patented data migration factory moved FirstBank's customers in June 2026. Technology spend is about $3.5 billion a year.

## What are the layers of PNC's AI and technology stack?

As PNC executives and filings describe them. PNC has not published an architecture diagram, a capital figure for the data-center build or the names of its hyperscalers.

## Does PNC build or buy its AI technology?

Mostly build, by stated policy. Asked in February 2026 which vendors PNC uses, Reilly answered 'everybody, and a lot in-house', adding that the bank is 'inclined to, you know, use our own cooking for the most part'. In October 2026 Demchak said success needs infrastructure that lets PNC work 'without vendor support, without compute costs coming from third parties and with your own personnel instead of vendors'. ([Investing.com](https://www.investing.com/news/transcripts/pnc-financial-at-bank-of-america-conference-strategic-growth-in-2026-93CH-4497725), [The Motley Fool (Yahoo Finance)](https://finance.yahoo.com/markets/stocks/articles/pnc-pnc-q3-2026-earnings-195851582.html), [Bloomberg](https://www.bloomberg.com/news/articles/2026-10-15/pnc-quietly-building-ai-agents-that-don-t-rely-on-tech-vendors))

The reason given is cost. Demchak told the Morgan Stanley conference in June 2026 that AI productivity 'can be taken away by the cost of tokens'; American Banker reported a spokesperson saying the aim is to avoid vendor lock-in and reliance on usage-based pricing while still mixing third-party and internal models by use case. ([American Banker](https://www.americanbanker.com/news/why-pnc-is-building-its-own-ai-factory), [American Banker](https://www.americanbanker.com/news/how-banks-are-looking-to-tame-their-growing-ai-bills))

What comes next, per Demchak on the Q3 2026 call, is 'the reengineering of the company using AI harnesses', which he expects to speed development and lower the cost of technology development and maintenance, followed by product delivery that aids revenue.

## Common questions

### Does PNC run its own AI data centers?

Yes, by its own account. The 2026 proxy describes a national data-center strategy with a new Eastern facility under construction and a Midwestern hosting site secured, and Demchak said on October 15, 2026 that GPU chips are already installed in PNC's data centers, with the cost showing up as rising depreciation.

### Which language models does PNC use?

A mix chosen per task. CFO Rob Reilly said in September 2026 that a harness picks the cheapest adequate model: frontier models through hyperscalers, open-weight models hosted in PNC data centers, and proprietary small language models. PNC has not named the hyperscalers or the open-weight model families it runs.

### How was the new PNC mobile app built?

With PNC's agentic development system: about 115 orchestrated AI agents handled development and testing with human review of their output, per Banking Dive in July 2026. PNC's release says the app runs on a patented data-streaming microservices architecture designed for rapid updates and embedded generative-AI assistance.

### What data foundation does PNC say AI needs?

Demchak said on the Q3 2026 call that the data lake and data configuration are 'all in one place, one source of truth', with policies digitized and HR systems that recognize agents. Ned Carroll has said 'AI, absent well-organized, well-curated data, is nothing more than interesting math on a whiteboard'.
