OpenAI Codex Adds Sites and Role-Specific Plugins
On June 2, 2026 OpenAI updated Codex with finance-focused plugins that can turn the coding agent into an on‑demand public‑equity analyst and investment banker. The release is part of a broader Codex expansion that includes a Plugins ecosystem and feature set (Sites, Annotations, role‑specific plugins) previously described by OpenAI; Codex is reported to have scaled rapidly (millions of weekly users) and some extended functionality is gated behind paid ChatGPT tiers and enterprise plans. The Substack piece also notes Anthropic has confidentially filed for an IPO, framing the Codex finance push as a strategic move in the AI‑for‑finance race and arguing it could reorder which firms capture value from agentic financial workflows.

OpenAI Launches Role-Specific Codex Plugins, Sites, Annotations
OpenAI expanded Codex with a set of role-specific plugins, a hosted 'Sites' feature, and in-place Annotations to accelerate enterprise and knowledge-worker use. An internal report and blog post say Codex now has more than 5 million weekly active users — a more than 6x increase since the desktop app launched in February 2026 — and that knowledge workers constitute about 20% of users, growing over three times faster than developer usage. The six new plugins target data analytics, creative production, sales, product design, public equity investing and investment banking; OpenAI says the bundles include integrations and contextual instructions to approximate specific jobs (the rollout references 62 popular apps and 110 skills across plugins). Sites (preview for Business and Enterprise) lets Codex deliver interactive hosted webpages; early partners include Wix, Base44, Replit, Lovable, Figma, Webflow and Emergent. OpenAI also recently launched the OpenAI Deployment Company JV backed by over $4 billion for enterprise deployments.
OpenAI Releases Major Codex Update
On 2026-04-16 OpenAI announced a major technical update to Codex that expands the coding assistant into an agentic desktop tool. New capabilities let Codex run in the background on macOS, open and control apps with a cursor (clicking and typing), and operate multiple parallel agents without interrupting a user’s active work. The release also adds an in-app browser for commanding web applications, a preview of persistent "memory" to recall past sessions, image-generation features for mockups and visuals, and extensive plug‑in support (the company and related reporting cite roughly 90–111 integrations including tools like CodeRabbit and GitLab Issues). OpenAI introduced a pay-as-you-go Codex pricing option for ChatGPT enterprise and business customers. The update positions Codex to compete more directly with Anthropic’s Claude products, which have introduced similar remote-desktop agent features.
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.
