OpenAI Launches ChatGPT for Financial Services
OpenAI launched ChatGPT for Financial Services, a specialized version of ChatGPT Work for financial institutions, designed to automate research, data analysis, and pitchbook creation. Developed with design partners Morgan Stanley and Evercore, it leverages GPT-6 Astra and integrates premium data from Daloopa, PitchBook, LSEG News, Crunchbase, and Quartr. Features include granular citations, enterprise-grade security, administrative controls, and optimized MCP connectors for S&P Global and FactSet. This positions OpenAI as a direct competitor to Bloomberg and FactSet in the financial data and investment banking workflow space, aiming to become the default working environment for investment banking through a hosted data architecture and integration strategy. The launch also highlights a broader trend of AI companies targeting specialized verticals with bundled data and AI capabilities, raising questions about junior banker training and hiring.
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.
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.
