View on XOpenAI Partners With Global Consultants to Scale Codex to 4 Million Users
OpenAI· Updated
OpenAI reached 4 million weekly active users on Codex and launched Codex Labs to help organizations deploy agentic workflows through expert-led workshops. By partnering with global systems integrators like Accenture and PwC, the company is shifting from individual developer tools to industrial-scale engineering automation.
OpenAI reached 4 million weekly active users on Codex, adding 1 million users in just two weeks. To support this growth, the company launched Codex Labs, a professional services initiative that brings experts into organizations to integrate agentic coding (AI that autonomously writes and tests code) into production environments.
This expansion follows the introduction of usage-based pricing, signaling a transition from experimental pilots to enterprise-wide adoption. By partnering with global systems integrators, OpenAI is building the human infrastructure needed to embed autonomous agents into complex, legacy software development lifecycles.
You can now apply for Codex Labs workshops or work with partners like Accenture and Infosys to scale deployments. This push extends recent work on unattended agent workflows and persistent screen memory, allowing Codex to handle broader knowledge work like generating project briefs and plans.
Still wondering? A few quick answers below.
Codex Labs is a new initiative where OpenAI experts work directly with enterprise teams through hands-on workshops and sessions. The goal is to help organizations identify high-value use cases, integrate Codex into existing software development workflows, and move from early pilots to repeatable, production-ready deployments of agentic AI tools.
OpenAI is collaborating with several leading global systems integrators to help enterprises adopt Codex at scale. These partners include Accenture, PwC, Infosys, Tata Consultancy Services, Capgemini, CGI, and Cognizant. These firms provide the expertise needed to modernize software delivery and support organizational change management for large-scale AI engineering deployments.
Organizations use Codex across the entire software development lifecycle for tasks like increasing test coverage, accelerating code reviews, and reasoning across large repositories. Beyond coding, teams use it for knowledge work, such as pulling context from multiple tools to generate project briefs, plans, and checklists, effectively turning scattered information into actionable work.
Codex is available for individual developers to download as an app, while enterprises can access it through ChatGPT Business and Enterprise plans. Organizations interested in the Codex Labs program or large-scale deployment can fill out an interest form on the OpenAI website or contact their dedicated account team to start the integration process.
As of April 21, 2026, Codex has reached more than 4 million weekly active users. This represents a significant growth milestone, as the platform added 1 million weekly users in just two weeks. This rapid adoption highlights the increasing shift toward agentic AI tools within both individual developer workflows and large engineering organizations.
