GPT-5.3-Codex-Spark was deprecated on September 14, 2026. The research preview is no longer available in the ChatGPT desktop app, Codex CLI, or IDE extension.

Switch to one of the recommended models, and update saved configurations, custom agents, and scripts that select gpt-5.3-codex-spark.

For faster responses with a supported model, see Fast mode.

Source: Official changelog entry

On October 14, 2026, GPT-5.5 will retire from ChatGPT, ChatGPT Work, and Codex on all plans, including consumer, Business, Enterprise, and Edu plans. This retirement does not apply to the OpenAI API.

For Codex with ChatGPT sign-in, switch from gpt-5.5 to gpt-5.6-sol (GPT-5.6 Sol) before the retirement date.

Update workspace defaults, saved model settings, managed configurations, custom agents, scheduled tasks, and scripts that still select gpt-5.5.

See GPT-5.5 retirement and workspace model availability for migration guidance.

Chat while you work

Keep ChatGPT close while you work in other apps. In the ChatGPT desktop app on macOS and Windows, you can now type a quick chat from the floating Pets controls and press Enter to send it. Use @ to add context and $ to choose a skill. Select the bell icon to follow progress in your threads, then select a thread to open the full conversation.

Choose a companion or show just the controls in Settings > Pets. Press Option+Space on macOS or Windows+Alt+P on Windows to show the controls and focus Quick Chat. Pressing the shortcut again keeps Quick Chat open. You can change Show pet in Settings > Keyboard shortcuts. To hide the controls, select Hide pet in the command menu or Settings > Pets.

On macOS, you can also send an appshot to the floating controls. Keep the main ChatGPT window in the background and choose Automatic for Appshot destination.

Learn more about Pets.

Share an app window on Windows

Appshots are now available in the ChatGPT desktop app on Windows. Press both Alt keys to share the frontmost app window with ChatGPT, then ask a question or describe what you want to do. An appshot includes a screenshot and available text from that window. You can customize the shortcut and choose which chat receives it in settings.

Other improvements and bug fixes

• Open files directly from a conversation's Sources panel, or download files that ChatGPT can't preview.
• Assign a Codex Micro key to Insert text and add your own reusable text to the active prompt without sending it.
• Reset a pet to its default size in settings. Custom pets also stay in place when you refresh their artwork.
• Keep unfinished comments on response text when you switch chats and return.
• ChatGPT dictation now respects your saved Main language preference.
• Keep tab widths and scroll positions more stable as you close browser tabs in full and split views.

npm install -g @openai/codex@0.154.0

Install with pip install --upgrade openai-codex==0.154.0 (Python 3.10 or later). This release includes the matching openai-codex-cli-bin==0.154.0 runtime.

• Add max and ultra reasoning-effort values. #39662

• Add ExternalMessage to synchronous and asynchronous run() and turn() calls. External content can start a turn or join an active regular turn with tool-level authority; it does not grant user authorization. Consumers receive independent event streams. #44086

• Add include_turns on resume/fork, turn_service_tier for one newly started turn, and source metadata. History selection changes the returned response, not model context. Existing defaults are preserved when these options are omitted. #44084

• Refresh generated protocol models and notifications, and preserve completion events that arrive before a turn-start response. #44032, #44400

Check these migrations when upgrading:

• HookMetadata wraps its handler in .root. Replace accesses such as hook.command with hook.root.command, checking hook.root.handler_type before reading handler-specific fields.

• Some previously unknown notifications now have typed payloads. Read named fields instead of .params; unknown or invalid payloads still use UnknownNotification.

• Manually constructed or late-joining turn handles receive events from their attachment point. Earlier output is not replayed, so collected results can be partial; attaching after completion can raise TransportClosedError. Use thread.read(include_turns=True) for saved history. Handles returned directly by thread.turn(...) retain events from when their request is sent.

Custom codex_bin overrides require CLI 0.151.0 or newer for ExternalMessage and the new history/per-turn options.

npm install -g @openai/codex@voice-cygwin-108b38cf67cbb731

CI-only build tools for native Windows voice releases. These archives are not included in Codex user packages.

• cygwin-build-inputs.tar.gz: 103 pinned Cygwin binary packages and the signed package index used by the offline build installer.

• cygwin-build-sources.tar: all 83 corresponding source package archives at the exact versions named by that index. It includes the upstream source, patches, and build recipes provided in Cygwin's -src packages.

• cygwin-source-map.json: each selected binary package mapped to its source archive and the source size and SHA-512 digest from the pinned index.

• CYGWIN-SOURCE-NOTICE.txt: source access and licensing notice.

The binary and source archive SHA-256 pins live in .github/scripts/voice-cygwin-snapshot.json in the Codex repository. Cygwin describes the licensing terms at https://cygwin.com/licensing.html.

New Features

• GPT-6-Astra is now available in the model picker and Amazon Bedrock catalogs. (#42879, #42619)

• Experimental worktree support lets you create isolated checkouts for new or forked sessions using --worktree or /worktree, then browse and resume them. (#42652, #43069, #43120, #43286)

• Answer questions inline while Codex continues working, using suggested choices or custom text without losing your main draft. (#42891, #42894, #42897)

• Windows sessions can now share a background Codex server, with daemon lifecycle commands and managed updates. (#42405, #42392)

• Vim editing gains R replace mode with undo and dot-repeat, plus more reliable Escape handling in legacy terminals. (#42194, #42584)

• Copying responses preserves formatting in rich-text apps, and /copy can copy status output or individual session fields. (#42847, #43055)

Bug Fixes

• Existing sessions pick up newly installed plugin tools and refresh skills and hooks after external plugin upgrades or rollbacks. (#42284, #42593, #42990)

• MCP connections coordinate OAuth token refreshes and surface login challenges when refresh fails, without automatically replaying rejected tool calls. (#42413, #42552)

• Startup avoids running workspace-controlled helpers before trust is established, and the macOS sandbox blocks terminal input injection. (#42324, #42590)

• Remote resume and fork operations preserve saved permissions; fresh sessions and forks respect server model defaults unless explicitly overridden. (#43330, #43177, #43355)

• Resuming a conversation open in another app now shows a read-only transcript with a retry option while preserving your draft. (#43253)

• Automatic approval reviews better preserve authorization context through compaction and reject approvals invalidated by new user instructions or answers. (#42844, #42852, #43442)

Documentation

• Updated the bundled OpenAI Docs skill with GPT-6-Astra migration, compatibility, and prompting guidance. (#42931)

npm install -g @openai/codex@0.153.0

New features

• Vim mode adds undo with u and redo with Ctrl+R, preserving complete drafts including pasted content and attachments. (#41941, #42140)
• The plugin CLI can list, install, and remove plugins from remote marketplaces. (#42150)
• tui.auto_recap = false disables automatic recaps while retaining manual /recap. (#42101)
• TUI history now includes complete patches, input sent to background terminals, and individual completed commands. (#41893, #42107)
• Plus and Team users receive an earlier warning when less than half their allowance remains in the approximate five-hour window. (#42142)

Bug fixes

• The TUI reconnects after an external app-server disconnect while preserving drafts and transcripts; uncertain or queued submissions pause for review. (#41911, #41916, #41918)
• Full Access skips Guardian review for confirmation-only actions, while User approval skips background Guardian scoring and prewarming; sensitive checks and input requests remain unchanged. (#42147, #42256)
• Guardian history survives compaction, restarts, and user forks, respects rollback, and isolates subagent history. (#41879, #42065)
• Remembered MCP approvals are scoped to the selected app account, and relative MCP executable paths start more reliably on macOS. (#42133, #42117)
• Rollout compression includes shared histories; codex exec resume handles compressed rollouts selected by working directory, and forks work with symlinked session roots. (#42039, #42135)

Configuration and API updates

• App-server thread metadata allows nullable model and reasoningEffort; structured asynchronous questions use request_user_input_async when enabled by the model catalog. (#42151, #42178)
• tui.disable_paste_burst replaces the top-level setting, with the old setting retained as fallback. (#41976)
• A disabled-by-default features.context_management.experimental_mode adds token-budget context, history notes, and new_context for eligible Plus/Pro/Pro Lite Codex-backend sessions; API-key, custom-provider, and temporary structured threads are excluded. (#42385)

• Resumed threads restore their saved working directory when none is supplied, and client metadata updates preserve filesystem permissions. (#41567, #41464)
• MCP tools remain available through cache refreshes and remote plugin changes; authentication retries use refreshed helper-provided headers. (#41336, #41344, #41396, #41400)
• Opening the model picker refreshes available models without losing the highlighted choice. (#41467)
• Fixed Windows sandbox execution with Microsoft Store PowerShell, subprocess hangs on terminal queries, and cursor-related display corruption in older JediTerm terminals. (#41227, #41436, #41673)
• Cloud task requests now reject untrusted backend URLs and disable redirects to protect saved credentials. (#41403)

Chores

Daybreak now offers two access tiers for approved defenders: Daybreak Blue and Daybreak Red. Use them to move from security findings to validated fixes in explicitly authorized engagements.

Start with Daybreak Blue for most defensive security work. It provides access to general-purpose models such as GPT-5.6 Sol for vulnerability discovery, secure code review, detection engineering, incident response, malware analysis, and patch validation.

Daybreak Red provides separately approved access to purpose-trained models such as GPT-5.6 Cyber for authorized vulnerability reproduction, exploit validation, penetration testing, red teaming, and complex system analysis.

Access requires approval through Trusted Access for Cyber and applies only to the approved identity, workspace or API organization and project, model, and product surface. Daybreak Red requires separate approval and provisioning; Daybreak Blue access doesn't grant access to Daybreak Red.

Work in an isolated environment, define your engagement scope, use least-privilege permission profiles, and configure Auto-review for eligible actions before they cross the sandbox boundary.

When you connect a supported plugin from the ChatGPT plugin directory, you can use Sign in with ChatGPT to create or link an account with that service in fewer steps. On participating partner sites, you can also select Sign in with ChatGPT to create or access your account.

This makes it easier to start working with supported tools in ChatGPT and Codex.

When you sign in, the partner receives only your name, email address, and profile picture, if available. You must still review and approve each plugin's requested access as a separate step.

npm install -g @openai/codex@0.146.0

New features

• Name new sessions with /new or /clear, pin important threads, and switch between side conversations without closing them.

Documentation

• Document shared HTTP-client usage, proxy-aware connection pooling, and safe outbound request handling.
• Clarify Windows drive-letter canonicalization for PathUri values.

Chores

• Publish release artifacts, channel metadata, and installer aliases through OpenAI-hosted release infrastructure, with GitHub fallback.
