Comcast

How they deploy

Deployment model

Comcast runs most of its AI inside Connectivity & Platforms, the segment led by CEO Steve Croney that includes Xfinity, Comcast Business and Sky. Charlie Herrin's Technology & Product organization designs and delivers products and runs the network, and in Jan 2022 both CTO Rick Rioboli and Chief Network Officer Elad Nafshi reported to Herrin; Comcast has not published the current lines. Customer experience works with outside agent vendors (Google, Cresta and Sierra), supported by Comcast's own personalized data models and offer recommendation engine (Oct 2026). NBCUniversal runs its own AI in advertising, Peacock and fan products, and Comcast plans to spin NBCUniversal and Sky off into a separate public company in about a year from Jun 29, 2026.

Model providers

Comcast rebuilt Xfinity Assistant on Google's Agent Development Kit and Agent Runtime with Gemini models (Apr 2026), and NBCUniversal's OLI Olympics guide was powered by Google Cloud's Gemini for the 2026 Winter Games. Cresta supplies an agentic front end for assisted care channels and Sierra is to handle agent-to-agent interactions (Oct 2026); Comcast has not said which models those vendors run for it. Comcast's own models include hundreds of marketing models with thousands of attributes for acquisition, upsell, win-back and retention (Apr 2026). The Nvidia edge trials test an ad engine on Decart real-time video models and a small business front-desk agent on Personal AI's small language model running on HPE ProLiant servers (Mar 2026).

Data and infrastructure

Comcast's AI runs in 3 places. Inside its own network, Broadcom DOCSIS 4.0 chips with AI engines sit in nodes, amplifiers and modems, Project Genesis had virtualized more than 50% of the footprint by Sep 2025, and Mike Cavanagh said in Jan 2026 that about 60% had moved to mid-split spectrum and a virtualized architecture. At its own edge, Comcast has about 200 edge data center and compute locations that could host Nvidia GPUs and says it has enough power there for AI workloads (Mar 2026). In public cloud, Xfinity Assistant's agents run on Google's Agent Runtime, and AWS has been Comcast's preferred public cloud since Jan 2018 and has hosted its 5G wireless core since Dec 2024. Comcast has not said where Cresta and Sierra process its customer data.

Leadership

AI, data and platform leaders

AI org map

No central AI office; AI built and bought inside each business, mainly Connectivity & Platforms

Comcast has no chief AI officer on its published leadership list. Connectivity & Platforms, led by CEO Steve Croney since Jan 1, 2026, holds the network, product and customer care work where most of Comcast's AI runs, through Charlie Herrin's Technology & Product organization, CTO Rick Rioboli and Chief Network Officer Elad Nafshi. NBCUniversal runs its own AI in advertising and streaming and is to become a separate company, led by Mike Cavanagh, in about a year from Jun 29, 2026, when Michael Angelakis becomes CEO of Comcast.

Comcast has not published how many people work on AI or data, and names no chief AI officer. Comcast's AI work sits in Connectivity & Platforms, where Charlie Herrin's Technology & Product organization holds the CTO, network and product teams, and in NBCUniversal's advertising and streaming groups. Bill Strahan, Connectivity & Platforms' head of human resources, told a Philadelphia Works board meeting in Mar 2026 that Comcast trains employees and leaders to work alongside AI tools and uses AI to raise coding productivity, according to the meeting minutes, without giving numbers.

Use cases

Comcast runs AI in production in network operations (Octave capacity management, self-repairing AI-powered amplifiers, WiFi tuning and outage diagnosis), in customer care (Xfinity Assistant on Google's Gemini and a Cresta agentic front end) and in marketing models, and NBCUniversal runs AI in ad sales and fan products. Comcast has published no return it credits to AI for any of these use cases or for the company: the roughly 20% fall in service contact rates and the more than 30 million service interactions removed in 2026 (Oct 2026) are workload measures with no cost or headcount figure attached.

Adoption

Comcast spread AI first through its network, with Octave from the early pandemic, an AI-enabled chipset announced with Broadcom in Oct 2023 and AI-powered amplifiers rolling out across all markets from Sep 2025, and then into customer care, where Xfinity Assistant was rebuilt on Gemini by Apr 2026 and Cresta and Sierra agents arrived in 2026. Comcast has published no count of employees who use AI tools: Bill Strahan described internal training for employees and leaders in Mar 2026 without figures, and Comcast's filings and calls give no user numbers. Customer-facing reach is the clearer measure, with AI checking 30 million network devices every hour (Sep 2025) and Comcast reporting about 20% fewer service contacts in 2026.

Quick answers

How does Comcast deploy AI?

Comcast deploys AI mainly in its broadband network, where AI chips in nodes, amplifiers and gateways tune and repair service, and in customer care, where Xfinity Assistant runs on Google's Gemini and Cresta and Sierra agents arrived in 2026. Comcast said in Oct 2026 that service contact rates fell about 20% as that AI spread, but has published no cost, revenue or headcount return it credits to AI and no count of employees using AI. NBCUniversal applies AI to ad sales, Peacock features and fan guides.

What does Comcast use AI for?

Comcast runs AI in production in network operations (Octave capacity management, self-repairing AI-powered amplifiers, WiFi tuning and outage diagnosis), in customer care (Xfinity Assistant on Google's Gemini and a Cresta agentic front end) and in marketing models, and NBCUniversal runs AI in ad sales and fan products. Comcast has published no return it credits to AI for any of these use cases or for the company: the roughly 20% fall in service contact rates and the more than 30 million service interactions removed in 2026 (Oct 2026) are workload measures with no cost or headcount figure attached.

Who leads AI at Comcast?

AI at Comcast is led by Charlie Herrin (President, Technology & Products, Connectivity & Platforms); Rick Rioboli (Chief Technical Officer, Connectivity & Platforms (as of Apr 2026)); Elad Nafshi (EVP and Chief Network Officer, Connectivity & Platforms). Ownership of AI on the org chart: No single AI chief; CTO Rick Rioboli and Chief Network Officer Elad Nafshi in Connectivity & Platforms.

What AI platform does Comcast use?

Comcast builds its network AI itself, from the Octave capacity platform to AI chips in FDX nodes, amplifiers and gateways, and buys customer care AI from Google Cloud, Cresta and Sierra; Xfinity Assistant was rebuilt on Google's Agent Development Kit (Apr 2026).

Which AI models does Comcast use?

Google's Gemini runs Xfinity Assistant and NBCUniversal's OLI Olympics guide, Cresta and Sierra supply care agents, and Comcast runs hundreds of its own marketing models (Apr 2026); Nvidia GPU trials at the network edge test Decart video models and a Personal AI small language model.

How many Comcast employees use AI?

Comcast has not said how many of its about 179,000 employees use AI tools; its AI-powered amplifiers were rolling out across all of its markets in Sep 2025, and Xfinity Assistant serves Xfinity customers.

What return has Comcast reported from AI?

Comcast has reported no business return it credits to AI since May 2025. CFO Jason Armstrong said on Oct 22, 2026 that, as AI spread through customer experience, service contact rates fell about 20% and more than 30 million service interactions were removed in 2026, but both are workload measures with no cost or headcount figure; the 20% fewer trouble calls and 35% fewer repair minutes Mike Cavanagh cited on Jan 29, 2026 come from FDX network upgrades with automation and AI combined; and the billions Armstrong expects from Comcast's cost transformation are not credited to AI. Comcast has not reported a company-wide AI rollout with a user count either, and names no single AI owner: CTO Rick Rioboli spoke for the rebuild of Xfinity Assistant on Google's Gemini (Apr 2026) and Chief Network Officer Elad Nafshi speaks for network AI. Comcast is at Experimenting on that in-window work, which includes Cresta and Sierra agents in care and Nvidia GPU trials at the network edge (Mar 2026); a care or network cost saving it credits to AI, or a reported count of employees using AI tools with a named owner, would move it to Piloting.

Open questions

• What cost saving does Comcast get from the roughly 20% fall in service contact rates and the more than 30 million interactions removed in 2026, and how much of it comes from Xfinity Assistant, Cresta and Sierra rather than simpler pricing and processes?
• How many of Comcast's about 179,000 employees use AI tools at work, and which tools has it licensed for them?
• Who owns AI across Comcast, given that no chief AI officer appears on its leadership page, and is Rick Rioboli still CTO after Jason Armstrong said in Oct 2026 that Comcast is bringing in new technology leadership?
• How much of the billions Comcast expects from its cost transformation, and how many of the nearly 1,000 layoffs in WARN notices, come from AI replacing work?
• What do the network AI tools return in avoided truck rolls, repair cost or outage minutes, separated from the FDX upgrades?
• Which models do Cresta and Sierra run for Comcast, and where is Comcast's customer data processed and stored?
• What did the Nvidia edge trials show, and when, if at all, will Comcast sell AI compute at its edge sites?
• How will AI teams, data and vendor contracts be split between Comcast and NBCUniversal when the separation closes?
• What share of NBCUniversal's ad sales now runs through AI buying agents, and with what effect on revenue or sales cost?
