OpenAI disclosed on May 18 that over 4 million developers use Codex weekly. On the same day, it announced a partnership with Dell Technologies to bring Codex into customers' on-premises and hybrid cloud environments.
The timing is no coincidence: with cloud-based Codex already reaching 4 million weekly active users, OpenAI is opening a second front.
What the Partnership Entails
The collaboration has two parts.
First: Codex integrates with Dell AI Data Platform. This is Dell's enterprise data management suite covering storage, organization, permissions, and compliance. Once connected, Codex can directly access internal codebases, documentation, operational knowledge, and business systems—without data leaving the enterprise.
Second: Codex connects to Dell AI Factory. Dell's infrastructure for enterprise AI workflows will support Codex, ChatGPT Enterprise, and other OpenAI API services for tasks like data preprocessing, system integration, testing, and deploying AI applications on-premises or in hybrid environments.
Ihab Tarazi, SVP and CTO of Dell's Infrastructure Solutions Group, stated: "Dell's enterprise-grade infrastructure with OpenAI's agentic AI...enterprises can deploy AI where enterprise data already lives."
In short: AI goes to where the data resides—not the other way around.
Why OpenAI Is Now Pursuing On-Premises
OpenAI has historically sold cloud-based services: Codex, ChatGPT, and APIs all run in the cloud. This works well in Silicon Valley, startups, and cloud-native enterprises.
But several customer segments refuse to move to the cloud:
- Finance: Regulated, customer data cannot leave enterprise boundaries.
- Defense/Government: Compliance requires physical isolation.
- Large manufacturing and energy: OT systems, factory data, and proprietary formulas cannot be hosted externally.
- European enterprises: GDPR and data sovereignty pressures.
These segments represent the wealthiest, highest-ASP portion of enterprise IT. OpenAI previously could not reach them. Codex has sold well for over a year, but penetration in finance, healthcare, and government has been blocked by data residency requirements.
Dell's AI Factory is ready-made, Dell's customer list is ready-made, and Dell's compliance framework is ready-made. By adapting Codex to run on Dell hardware, OpenAI effectively expands its enterprise reach into the half of the market it previously could not access.
Codex Is Evolving Beyond Coding
OpenAI quietly noted in the announcement: "Codex is expanding beyond coding."
According to the official description, Codex is no longer just about writing code. Customers are already using it for:
- Gathering context across tools
- Preparing reports
- Routing product feedback
- Qualifying sales leads
- Drafting follow-up emails
- Coordinating work across business systems
Note the shift in language. A year ago, Codex was called an "AI coding assistant." Now OpenAI describes it as an "AI Agent." Its functionality has expanded from IDE code completion to the entire software development lifecycle and general knowledge work.
This explains why OpenAI is investing in on-premises with Dell: if Codex were just a completion tool, where it runs would matter little. But if it becomes the agent that "reads all data and runs all processes" within an enterprise, it must be tightly coupled with local data.
The Microsoft Relationship Gets Interesting
An unavoidable topic: the OpenAI-Microsoft relationship.
Microsoft's Copilot has its own enterprise deployment story, running on Azure and Microsoft 365. With the Dell partnership, OpenAI now has an enterprise infrastructure partner independent of Microsoft.
Looking back, OpenAI's moves over the past year have become clearer:
- April: Codex runs on Cerebras chips (bypassing NVIDIA)
- Late April: New agreements with AWS and Google Cloud (bypassing Azure exclusivity)
- May: On-premises partnership with Dell (bypassing Microsoft's enterprise channel)
This is no coincidence. OpenAI is diversifying its sales channels ahead of a potential IPO. While a seven-year exclusivity agreement ties it to Azure, post-IPO shareholders will not tolerate a single revenue leg.
A Detail That Shows the Urgency
OpenAI's announcement cited "over 4 million developers using Codex weekly." Cursor's ARR is reportedly around $20 billion, with valuation talks at $50 billion; Anthropic's Claude Code grew sixfold in a year—the AI coding tool market is fiercely competitive.
Bringing Codex on-premises won't immediately win over cloud-loving developers using Cursor. But landing large contracts in finance, healthcare, and defense—where each deal can outweigh a thousand small Cursor customers—is the real prize.
In the coming quarters, whether Dell discloses the first batch of Codex on-premises banking clients will be a key indicator to watch.
