OpenAI Folds ChatGPT Work and Codex Into One Desktop App; Atlas Browser Gets August 9 Sunset
The July 9 consolidation merges Chat, Work and Codex into a single ChatGPT desktop app — renaming the old client 'ChatGPT Classic' and scheduling the Atlas browser's retirement for August 9.
OpenAI launched ChatGPT Work on July 9, 2026, and simultaneously merged the standalone Codex app into a unified ChatGPT desktop app for Mac and Windows with Chat, Work and Codex modes, per Developers Digest's coverage of OpenAI's announcement.
Context
The consolidation is OpenAI's answer to a fragmented product surface: separate apps for chat, coding and browsing had multiplied since 2024. The July 9 GPT-5.6 GA provided the model layer for unifying them.
What changed
- ChatGPT Work: a GPT-5.6-powered agent that pulls context from connected apps — Google Drive, Slack, Salesforce and 1,400+ more per launch coverage — and returns finished docs, sheets, slides and web apps. Live at launch for Pro, Enterprise and Edu plans, rolling out to Plus and Business afterward, per Radical Data Science.
- Unified desktop app: the Codex app merges into the ChatGPT desktop app; the older client is renamed "ChatGPT Classic." Codex-in-desktop gains a PR-review sidebar and multi-repo support, per release-note tracking.
- Atlas sunset: the Atlas AI browser is scheduled to retire August 9, 2026, per release-notes-based reporting. Unified search (July 14) and 5,000-character custom instructions (July 15) followed in the same consolidation wave.
Why it matters
This is OpenAI's "superapp" play: one client as the distribution surface for GPT-5.6 across consumer, work and developer modes. It also creates real deprecation risk — Atlas users and Codex-standalone workflows have hard migration dates, and the consolidation drew user backlash over merged-app disruption.
Details
Work's connector breadth (1,400+ apps) positions it against Microsoft's Copilot inside enterprise data estates. Plan gating means Free and Go users see Terra-tier models inside Work and Codex, while Sol and ultra reasoning remain paid-tier features.
Limitations and caveats
The August 9 Atlas retirement date comes from release-notes-based secondary reporting; connector counts are launch-coverage figures. User-backlash characterizations reflect community coverage rather than published metrics.
