OpenAI is taking the next step in scaling Codex — and it’s enlisting two of the world’s largest IT services companies to do it. On April 21, the company launched a formal partner program for Codex, with Cognizant and CGI as its first official systems integrators.
What’s Changing
Until now, Codex has been primarily a tool for individual developers and teams. Now OpenAI wants to reach enterprise clients who can’t implement Codex on their own — and there are many. Cognizant ($21 billion in annual revenue, active in financial services, healthcare, and manufacturing) is embedding Codex directly into its Software Engineering Group. CGI is giving its engineers and consultants early access to new Codex features.
The model is straightforward: OpenAI provides the technology, the big IT consultancies carry it into the corporate world. Joint go-to-market efforts, training bootcamps, and innovation programs included.
The Numbers
The growth numbers are impressive: Codex now has 3 million weekly active developers — up from 2 million in mid-March. Within ChatGPT Business and Enterprise, user numbers have grown 6x since January. The enterprise segment now accounts for over 40 percent of OpenAI’s revenue and is on track to reach parity with consumer revenue by end of 2026.
Beyond Writing Code
What Codex does inside enterprises goes well beyond code generation. The partnerships target legacy code modernization, automated vulnerability detection, code review automation, and broader agentic workflows. In large enterprises with millions of lines of legacy code, that’s a massive market.
The Bigger Picture
With this move, OpenAI is doing what every enterprise software company eventually must: build a channel. Direct sales relationships aren’t enough when you want to land Fortune 500 clients. Cognizant and CGI aren’t random choices — both have deep relationships with the conservative industries that need AI coding tools most but adopt them slowest.
The competition with Claude Code and Google Antigravity just got more intense. Anthropic is betting on a developer-first approach, Google on IDE integration — and OpenAI is now leveraging the big consulting machine.
