ChatGPT

Overview

Freshness note: AI products change rapidly. This profile is a point-in-time snapshot last verified on July 10, 2026.

ChatGPT is OpenAI’s general-purpose AI workspace for questions, research, writing, analysis, files, connected tools, and multimodal work. The July 9, 2026 release makes the product structure clearer: Chat handles conversational help, ChatGPT Work handles longer research and finished deliverables, and OpenAI Codex remains the dedicated software-development agent.

The new ChatGPT desktop app brings those experiences together on macOS and Windows. Existing Codex app users can update in place, while users of the previous desktop client may temporarily retain ChatGPT Classic alongside the new application. Web and mobile continue to carry Chat and eligible cloud Work conversations, but Codex is not a selectable mode on those surfaces.

Key Features

Chat remains the fast lane for questions, search, brainstorming, rewrites, planning, and short analysis. It supports files, projects, memory controls, images, data analysis, apps, and plan-dependent agent capabilities. Specialized products such as ChatGPT for Clinicians keep their own eligibility and governance rules.

Work adds multi-step execution and review-ready artifacts. It can research across files and plugins, create documents, spreadsheets, presentations, reports, and Sites, and keep recurring work moving through Scheduled Tasks. In the desktop app, it can also use local files, the built-in browser, and approved desktop applications.

Codex adds repository, terminal, diff, pull-request, and developer-tool workflows. The desktop app can switch between Work and Codex, while Quick Chat preserves the familiar conversational experience. OpenAI is also replacing the old App Directory with a Plugin Directory whose bundles can include skills, MCP-backed apps, and workflow templates.

The GPT-5.6 family is available across Work and Codex where plans and workspace policies expose it. Standard Chat model routing remains a separate product decision, so do not assume that every Chat, Work, Codex, cloud, or API task uses the same model.

Strengths

ChatGPT’s main strength is breadth without requiring a custom integration. A user can begin with a question, collect context, move into a substantial Work task, and hand software-specific execution to Codex without leaving the same product family.

The unified desktop app also reduces the old split between conversational ChatGPT and the more operational Codex app. Local files, browser work, plugins, and computer use can now sit closer to the task that needs them.

Limitations

The product is not one perfectly synchronized workspace yet. At launch, cloud Work conversations do not appear in desktop Work, desktop threads remain local, and Codex tasks are reached from mobile through Remote rather than normal chat history. ChatGPT Classic may also remain installed during the desktop transition.

Plan, region, workspace policy, credit balance, and connected-service permissions materially affect availability. ChatGPT Atlas is also being discontinued rather than merged automatically: Atlas stops working on August 9, 2026, and its bookmarks, tabs, and browser history do not transfer by themselves.

Practical Tips

Choose the surface before choosing the prompt. Use Chat for advice or a short answer, Work for a multi-step deliverable, and Codex for repository or software-development work. Keep each task bounded, name the sources it may use, and state which actions require approval.

Treat plugins and Computer Use as permission-bearing tools, not invisible conveniences. Prefer structured integrations where available, grant only the access needed for the task, and inspect generated files, external writes, and important claims before using them.

Verdict

ChatGPT is now less a single chat interface and more a unified work system. It remains one of the strongest general entry points for AI-assisted work, provided users understand the boundaries between Chat, Work, Codex, cloud history, local execution, and shared team agents.
