NTT DATA Scales Codex, Cuts Incident Analysis to 30 Minutes
NTT DATA Group deployed ChatGPT Enterprise companywide and expanded OpenAI's Codex to about 9,000 employees as part of an AI-driven transformation. After starting a strategic partnership with OpenAI in May 2025, the company set up an internal OpenAI Center of Excellence to drive adoption, governance, and best practices. An early Codex use case automated a complex incident analysis that previously required five senior engineers and three days, reducing it to 30 minutes. Codex adoption has spread beyond engineering into nontechnical functions for tasks like file organization, Excel analysis, and expense extraction, supported by security guidelines and training that increased weekly active users by 1.4x.
Demonstrates large-scale enterprise adoption of LLM-based agents with measurable efficiency gains (30-minute incident analysis) and governance practices that could influence other enterprises, but it is not a platform-level policy or industry-shifting announcement.

OpenAI scales Codex to enterprises with Codex Labs
OpenAI reports rapid growth in Codex usage—weekly developer users rose from over 3 million to more than 4 million within two weeks—and says enterprises are expanding Codex across software lifecycles and non-engineering workflows. To accelerate adoption, OpenAI launched Codex Labs, a hands-on program that embeds OpenAI experts in organizations to run workshops, identify high-value use cases, and help move pilots to production. OpenAI is also partnering with global systems integrators (GSIs) including Accenture, Capgemini, CGI, Cognizant, Infosys, PwC and Tata Consultancy Services to scale deployments. The post cites customer examples (Virgin Atlantic, Ramp, Notion, Cisco, Rakuten) using Codex for test coverage, code review, feature development, repository reasoning, and incident response, and includes a quote from Lan Guan, Accenture’s Chief AI Officer, on productivity gains.
OpenAI Codex & ChatGPT Work Hit 10M Users
OpenAI’s Codex and the newly launched ChatGPT Work have rapidly scaled: Codex MAU grew more than 10x since January 2026 and, less than two weeks after ChatGPT Work’s July 9 launch, OpenAI reported a combined 10 million users for Codex and ChatGPT Work. The company says Codex now powers ChatGPT Work, expanding use from developers into knowledge workers (who represent ~20% of Codex users and are reportedly growing over three times faster than developers). The launch bundles a shared agent harness, artifacts (Sites), plugins, memory (Chronicle), and multi‑agent/sub‑agent modes (including an “Ultra” mode), and coincided with a new model release (GPT‑5.6). The interview explores product design tradeoffs, internal adoption signals, and how agentic interfaces change productivity and workflows.
Agents Transform Knowledge Work
OpenAI reports that agentic AI — exemplified by its Codex agents — is shifting knowledge work from short, single chatbot interactions to delegated, long‑horizon tasks that can run for minutes or hours and orchestrate tool calls. Internal usage data through mid‑2026 show rapid adoption: by May 2026 a large majority of sampled individual users made Codex requests estimated to exceed 30 minutes (80.6%) or one hour (70.2%), and 25.6% made requests estimated to exceed eight hours. Codex became the primary AI tool across OpenAI departments (engineering first; Legal, Finance and Recruiting by ~April 2026), accounting for the majority of output tokens (over 85% per worker and 99.8% of weekly output tokens). Non‑developer adoption also surged since August 2025 (137x individual, 189x organizational, 12x internal). OpenAI frames these patterns as evidence that agentic tools enable longer, more complex and cross‑functional work, with implications for workflow design and labor skills.
