📋 Оглавление
Источник: OpenAI announcement 2026-07-09 + public press. Rollout/pricing subject to change.
01 · Event summary: три параллельных изменения 09.07.2026
В день релиза GPT-5.6 OpenAI выполнила structural refactor desktop stack: standalone Codex App → EOL, capabilities merged into ChatGPT desktop (macOS + Windows); launched ChatGPT Work — long-horizon knowledge-worker agent с cross-app orchestration и production deliverables.
Hard metrics: 1400+ tools в unified Plugins Directory; Codex ~5M WAU, >1M non-coding workflows; Computer Use latency improvement под GPT-5.6 inference stack. Это не point release — это super-app composition: Chat + Agent + Coding + file I/O + cron-like Scheduled Tasks + plugin mesh.
02 · Risk surface — три блокера перед production rollout
- Codex EOL → permission model expansion. Post-merge surface = Chat + Work + Codex + Computer Use + plugin OAuth scopes. IT must re-audit TCC/Accessibility grants; data migrates via update, но attack surface растёт.
- Usage-based billing без public unit economics. Work inherits Codex metering — multi-hour autonomous runs burn quota непредсказуемо. Pipeline Slack→Drive→Report→Gmail требует baseline measurement до scale-out.
- Work vs Cowork — orthogonal architectures. Cowork (Apr 2026): local folder sandbox + native M365 add-ins. Work: cloud SaaS breadth + desktop Computer Use. Wrong pick = duplicate subscriptions + elevated macOS privileges на primary machine.
03 · Delta changelog
3.1 Codex App EOL — capability persistence
Effective 2026-07-09: Codex desktop binary deprecated; runtime merged into ChatGPT desktop. Migration path: in-place update — projects, settings, workflows preserved. Codex default launch mode supported; macOS может retain legacy Codex app icon. Mobile ChatGPT client reads desktop Codex project state.
Legacy ChatGPT desktop → renamed ChatGPT Classic.
3.2 Tri-mode shell: Chat / Work / Codex
| Mode | Function | Target |
|---|---|---|
| Chat | Dialog / Q&A | All tiers |
| Work | Cross-app agent, deliverable output | Knowledge workers |
| Codex | Code review, PR sidebar, multi-repo | Engineering teams |
All plans incl. Free — full tri-mode на desktop; Work на web/mobile restricted для Free (§08).
3.3 ChatGPT Work execution model
Pipeline: Plan Mode approval gate → context fetch (Slack/Gmail/Drive via plugins) → multi-step autonomous execution (hours) → deliverable artifact (doc/xlsx/ppt/web app via Codex Sites).
04 · Work subsystem — component breakdown
4.1 Plugin mesh: 1400+ integrations
- Collab: Slack, Microsoft Teams, Zoom
- Storage: Google Drive, SharePoint, Dropbox
- Mail/Calendar: Gmail, Outlook, CRM calendars
- GTM: Salesforce, HubSpot, LinkedIn, Adobe
- Dev: GitHub, Canva, Zapier
Invocation: @AppName targeted pull или natural-language task spec.
4.2 Plan Mode — human-in-the-loop gate
Numbered step plan emitted pre-execution; user edit/approve required. Critical для financial reports, PII exports, high-stakes automation.
4.3 Computer Use (desktop-only)
Local file R/W, embedded multi-tab browser, UI automation (click/type/drag), one-shot или Scheduled Tasks (time/trigger/cron semantics).
4.4 Deliverables ≠ chat drafts
Documents (Word/PDF), spreadsheets (Excel/Sheets + formulas), decks (Slides/PPT), web apps (Codex Sites interactive output).
4.5 Scheduled Tasks
Agent pipelines continue off-keyboard — async progression без active user session.
05 · Codex post-merge — capability deltas
- ✅ Diff inline edit — mutate hunks in-place, no view hopping
- ✅ PR sidebar review — zero context switch
- ✅ Faster Computer Use — GPT-5.6 inference path
- ✅ Multi-repo projects — single workspace, N repositories
Default Codex launch mode ≈ pre-merge standalone UX.
06 · Work vs Claude Cowork — architecture matrix
| Dimension | ChatGPT Work | Claude Cowork |
|---|---|---|
| Runtime | Cloud + desktop hybrid | Local desktop-first |
| File I/O | Desktop: local FS; Web: upload | Sandboxed local folder |
| Integrations | 1400+ plugins | 20+ official MCP, native M365 |
| Fit | Cross-web SaaS orchestration | File-heavy doc pipelines |
| Non-tech UX | High | Very high |
| Billing | Usage-metered | Seat-based (Pro from $20/mo) |
| Free tier | ✅ Desktop (capped) | ❌ |
| M365 add-in | Web-only | ✅ Native Word/Excel/PPT |
Decision rule: browser/SaaS-primary → Work; local files/M365-native → Cowork. Production teams often run both.
07 · 5-step desktop runbook
- Download: chatgpt.com/download (macOS/Windows)
- Existing Codex install → update triggers auto-migration
- Top-nav → Work mode
- Plugins Directory: OAuth Gmail, Slack, Drive
- Task spec → Plan Mode review → confirm → execute
Web/mobile rollout schedule
- Pro, Enterprise, Edu: live 2026-07-09
- Plus, Business: rolling days after
- Free: web/mobile limited — use desktop for full Work
Pro+ tiers: mobile task monitor/management; heavy compute remains desktop-bound.
08 · Pricing & metering — no separate SKU
Work bundled into existing subscription tiers; usage-metered like Codex. Enterprise Admin Console: workspace defaults, group caps, per-user overrides, credit request flows. No public per-task unit price published.
| Tier | USD/mo (US) | Work access |
|---|---|---|
| Free | $0 | Desktop capped |
| Go | $8 | Desktop extended |
| Plus | $20 | Desktop + web/mobile |
| Pro | $100–$200 | Full access, max quota |
| Business/Enterprise | Team quote | Full + Admin Console |
09 · Strategic vectors — три architectural bets
- Competition shifts from model leaderboard → workflow embedding depth. GPT-5.6 matters; Work anchors inference in desktop/Slack/Drive execution paths.
- Codex TAM expansion beyond developers. >1M of 5M WAU already non-coding — merge lowers agent capability floor for knowledge workers.
- Super-app client emerging. Single binary: Chat + Agent + Coding + FS + scheduler + 1400-plugin mesh.
10 · FAQ
Q: Standalone Codex App?
A: EOL 2026-07-09. Update in-place; state preserved.
Q: Free + Work?
A: Desktop yes (capped); web/mobile incomplete for Free.
Q: Work vs Agent mode?
A: Work = long/cross-app/deliverables/Plan Mode; Agent = short single-step.
Q: Cost predictability?
A: Usage-metered; run Plan Mode pilot first.
Q: Codex projects lost?
A: No — migration preserves; mobile can read desktop projects.
Q: Mobile Work?
A: Pro/Enterprise/Edu first; monitor mobile, execute heavy on desktop.
Q: Work vs Operator?
A: Operator = browser agent; Work = plugins + local FS + multi-hour deliverables.
Q: Migrate from Cowork?
A: Work wins cloud/SaaS + free desktop tier; Cowork wins local/M365. Many teams: dual deploy.
11 · Isolated Mac: acceptance testing без pollution primary machine
Computer Use triggers local FS access, browser control, production OAuth (Gmail/Slack). Granting full plugin scope на primary MacBook = file deletion risk, Keychain token co-mingling, Codex multi-repo clone collision с Xcode toolchain. Parallel Work + Cowork = doubled Accessibility/Screen Recording TCC prompts.
Windows/Linux cannot reproduce macOS-specific paths: Codex default icon, Metal-accelerated Computer Use latency, Xcode/GitHub Desktop side-by-side dev flows. Recommended acceptance cycle: daily-rented M-series Mac mini → update Codex → tri-mode switch → minimal OAuth pilot → environment destroy. Pricing/SSH: руководство цен Mac mini M4; agent isolation pattern: Cursor Agent Skill guide.
