OpenAI launches ChatGPT Pro to boost Codex usage
OpenAI introduced a new ChatGPT Pro subscription tier aimed at developers using its Codex coding agent. The offering includes a $100/month (≈€103) Pro plan and a $200/month Pro plan with significantly expanded Codex usage limits (5x and 20x versus ChatGPT Plus, respectively); OpenAI temporarily increases the $100 tier’s boost to 10x until May 31. The update follows Codex reaching three million weekly active users; CEO Sam Altman said usage limits will be reset at each additional million up to ten million. OpenAI recently released a Codex mobile app, the GPT-5.3‑Codex model, and the Frontier development platform. The Pro subscription provides access to GPT-5.4 Pro Reasoning, unlimited file uploads, GPT‑5.3 usage, individual GPTs, and experimental features. OpenAI is also testing a parallel workflow feature called Scratchpad. Thibault Sottiaux from the Codex team clarified rate-limit wording publicly on X.
OpenAI (a major platform) changed subscription tiers and usage limits for Codex, affecting developer access, LLM monetization and agentic workflows; such platform-level pricing and feature changes can influence adoption, operational costs and integration choices across the AI and developer ecosystem.

OpenAI Adds $100/month ChatGPT Pro Tier for Codex
OpenAI introduced a new $100/month ChatGPT Pro tier targeted at heavy Codex (coding) users, offering five times the Codex capacity of its $20 Plus plan. The company retained the $20 Plus plan (ad-free) and continues to offer a $200/month Pro tier (also ad-free) — the $200 tier is currently not listed on the pricing page but remains available and provides about 20× the Plus limits. Free and an $8/month Go plan (both ad-supported) remain available. OpenAI said the $100 tier will deliver temporarily higher Codex limits through May 31 as a promotional boost. The company framed the pricing move as a competitive response to Anthropic’s $100 Claude Code option. OpenAI reported Codex usage exceeding three million weekly users, up 5× in the past three months with ~70% month-over-month growth; prior reports also cite a Codex standalone Apple app and a reported run-rate revenue above $2.5 billion as of February.
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.
OpenAI Adds Pay-As-You-Go Codex Seats for Teams
OpenAI announced that teams on ChatGPT Business and Enterprise can now add Codex-only seats to workspaces with pay-as-you-go pricing, billed by token consumption and without rate limits. The company also lowered ChatGPT Business annual pricing from $25 to $20 per seat. Eligible ChatGPT Business workspaces can receive promotional credits ($100 per new Codex-only team member, up to $500 per team) for a limited time. OpenAI highlighted accelerating Codex adoption—Codex users within ChatGPT Business and Enterprise have grown sixfold since January—and cited usage stats including over 9 million paying business ChatGPT users and more than 2 million weekly Codex builders. The Codex app, plugins and automations were promoted as recommended ways to get started.
