CGI (NYSE: GIB), one of the largest independent IT consulting firms in the world with 94,000 professionals and CA$15.91 billion in fiscal 2025 revenue, announced a strategic expansion of its global partnership with OpenAI on April 21, focused on Codex deployment across enterprise clients.
Early Access, Joint Go-to-Market
The expanded partnership gives CGI early access to OpenAI’s latest agentic capabilities and includes joint go-to-market strategies, training bootcamps, and regional innovation programs, according to the PRNewswire announcement. CGI joins what OpenAI describes as “a select group of partners” with early access to new releases.
“Codex is becoming a powerful workspace for managing agents across software development and business workflows,” said Denise Dresser, OpenAI’s Chief Revenue Officer, in the announcement. She cited CGI’s “deep expertise in large-scale software transformation” as enabling deployment across legacy code modernization, code review automation, vulnerability detection, and application development.
Tens of Thousands Already Using Codex
CGI initially adopted Codex within software engineering, then extended it across roles. Tens of thousands of CGI engineers, experts, and consultants now use OpenAI technologies including Codex to embed agentic AI into daily work: automating tasks, improving workflows, and accelerating delivery, according to the announcement.
The firm is collaborating with OpenAI on client deployments across government, public safety, and global commercial sectors.
Consulting as Agent Distribution Channel
CGI CTO Dave Henderson framed the partnership around integration, not tooling. “Generating business outcomes from Agentic AI isn’t just about tooling or adoption, it’s about engineering, embedding and integrating agents at the core of how work is done,” Henderson said in the announcement.
The deal positions major consulting firms as a distribution channel for agent platforms. Rather than enterprises adopting Codex directly, CGI acts as the integration layer: bringing domain expertise, compliance knowledge, and deployment methodology that enterprises need but OpenAI doesn’t provide. The model mirrors how consulting firms historically distributed ERP systems and cloud migrations. For OpenAI, each CGI client engagement becomes a Codex deployment; for CGI, agentic AI becomes a new billable practice area layered onto existing modernization and managed services contracts.
The announcement follows OpenAI’s same-day release of GPT-5-Codex, a GPT-5 variant optimized for agentic coding, which becomes the default model for Codex cloud tasks.
