ChatGPT & Codex changelog

GPT-5.4 and GPT-5.4 mini retire from Codex on August 31

Fri, 31 Jul 2026 00:00:00 GMT

# GPT-5.4 and GPT-5.4 mini retire from Codex on August 31 On August 31, 2026, GPT-5.4 and GPT-5.4 mini will no longer be available in Codex for users signed in with ChatGPT. GPT-5.4 and GPT-5.4 mini will remain available on the OpenAI API and Codex sessions authenticated with an API key. Switch to their recommended replacements: - Replace `gpt-5.4` with `gpt-5.6-terra` (GPT-5.6 Terra). - Replace `gpt-5.4-mini` with `gpt-5.6-luna` (GPT-5.6 Luna). Before the cutoff, update workspace defaults, saved model settings, managed configurations, custom agents, and scheduled tasks that use either model. See [Codex models](/codex/models#deprecated-codex-models) and [workspace model availability](/codex/enterprise/workspace-model-availability) for details.

Browser upgrades, multi-repository review, and image editing

Thu, 30 Jul 2026 00:00:00 GMT

# Browser upgrades, multi-repository review, and image editing The latest ChatGPT desktop app update makes browsing, reviewing code, and editing generated images faster and easier. ### Browse and find context faster - Type in the built-in browser's address bar to revisit pages from your browsing history or search Google when there's no match. - Manage your browsing history in Settings, and let ChatGPT search that history when a task needs to find a page you visited before. - Use the Chrome extension to mention open tabs or bring highlighted page text into your side chat. - Ask questions about any YouTube video in the Chrome extension and get answers in seconds. - Right-click a webpage and select **Ask ChatGPT**. Learn more about the [built-in browser](/codex/browser) and the [Chrome extension](/codex/chrome-extension). ### Review changes across repositories See all repositories in a [multi-folder project](/codex/projects#use-local-projects-for-folders-and-codebases) and the lines changed in each one. Select **Review** to inspect diffs across those repositories without switching between separate review views. ### Refine generated images Open generated images in an expanded viewer, and switch between **Focused view** and **Canvas view**. Add comments across images, choose the ones you want, and send targeted edits without leaving your conversation. Learn more about [image generation](/codex/image-generation). ### Other improvements and bug fixes - Added a new "Activity view" in the sidebar to view which chats you engaged with recently and require attention. Click the bell or use Cmd/Ctrl+Opt+U to change to the new view. - Updated browser settings to show only supported browsers. - Improved Windows installation reliability when package file paths are long. - Other performance and bug fixes.

Sign in with ChatGPT (beta)

Wed, 29 Jul 2026 00:00:00 GMT

# Sign in with ChatGPT (beta) Sign in with ChatGPT is beginning to roll out in beta across select plugins and partner sites, starting with Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel. 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.

ChatGPT Voice and multi-folder projects

Thu, 23 Jul 2026 00:00:00 GMT

# ChatGPT Voice and multi-folder projects Powered by GPT-Live, ChatGPT Voice lets you talk through work and coordinate tasks in Chat, Work, and Codex in the ChatGPT desktop app. Start a new chat or task in voice mode, then ask ChatGPT to start, check, or steer work in other threads. On macOS, turn on **Screen context** to share an [appshot](/codex/appshots) of your frontmost window. Voice is available with Plus, Pro, Business, Edu, and Enterprise plans in the desktop app and through [Remote on iOS](/codex/remote-connections#set-up-mobile-access). Local projects in the ChatGPT desktop app can now include multiple related folders. From a project's menu, select **Edit project** to add folders and choose the primary folder. New chats, Git operations, and automatic discovery of `AGENTS.md`, skills, and `config.toml` use the primary folder. Secondary folders remain available for file search, reading, and editing. Get started with [ChatGPT Voice](/codex/features/voice) and [multi-folder local projects](/codex/projects#use-local-projects-for-folders-and-codebases).

Codex CLI Release: 0.145.0

Tue, 21 Jul 2026 00:00:00 GMT

New Features

Added experimental paginated thread history with efficient resume, search, persisted names, sub-agent support, and memories. (#33364, #33907, #34085, #34229, #34386)

Added experimental Amazon Bedrock login, custom endpoint and authentication support, and GPT-5.6 Sol as the default Bedrock model. (#31327, #33170, #33175, #32288, #33695)
Added audio inputs and tool outputs, including common local audio formats, and introduced streaming realtime V3 conversations. (#33261, #33856, #33932, #34080, #34385)
Stabilized the opt-in multi-agent V2 experience with configurable sub-agent models, reasoning levels, concurrency, restored roles, and improved agent navigation. (#33550, #33631, #33657, #33841, #34383)
Added secure, clickable inline visualization links in the terminal UI. (#33925, #34217, #34346)

Bug Fixes

Editing an earlier prompt or retrying a safety-buffered turn now creates a contextual branch, preserving the original conversation, attachments, and mention bindings. (#33201, #33207, #33211)
Improved terminal responsiveness for long conversations and streamed output through incremental Markdown rendering, fewer redraws, caching, and bounded command output. (#34045, #34049, #34216, #34223, #34359)
Prevented slow or conflicting MCP startup and authentication flows by enforcing startup timeouts, avoiding blocking OAuth discovery, serializing refreshes, and reusing tool catalogs safely. (#32229, #32781, #32825, #33184, #33297)
Improved Windows execution and sandbox reliability, including native exec-server sandboxing, network-proxy enforcement, hidden helper consoles, and correctly quoted hook commands. (#32849, #32857, #33926, #34423)
Fixed compact release-metadata parsing and macOS code-mode installation, with an in-process fallback when the external code-mode host is unavailable. (#31667, #31876, #31899)
Strengthened safety and approval handling with better forced-rm detection, consistent full-access confirmation, and preserved rejection reasons across tools. (#32989, #33464, #34400)

Documentation

Updated the bundled OpenAI Docs skill with current GPT-5.6 model resolution, prompting, and migration guidance across macOS, Linux, and Windows. (#31842, #33121)

Chores

Migrated bundled GPT-5.4 selections and internal uses to the corresponding GPT-5.6 Terra and Luna variants. (#33173)
Reduced startup and large-context overhead with concurrent skill/plugin discovery and more efficient remote compaction. (#31566, #33369, #33423, #34431)
Updated the packaged ripgrep binary to 15.2.0. (#34384)

Codex CLI Release: 0.143.0

Wed, 08 Jul 2026 00:00:00 GMT

New Features

Remote plugins are now enabled by default, with richer catalog rows, npm marketplace sources, and visible remote/local versions. (#30297, #26705, #29375, #30981)
Codex can route authentication and Responses API traffic through macOS and Windows system proxies, including PAC and WPAD configurations. (#26708, #26709, #31335)
Added codex remote-control pair for generating manual pairing codes from a running daemon. (#29913)
Added Amazon Bedrock GPT-5.6 Sol, Terra, and Luna models, with first-class support for max reasoning effort. (#30285, #30467)
MCP tools now use tool search by default, and ChatGPT-hosted MCP servers can explicitly use session authentication. (#29486, #29733)
App-server clients can inspect environments, list descendant threads, and fork history through a specific turn. (#30291, #29591, #30277)

Bug Fixes

Fixed Windows ConPTY input handling for line endings and backspace, plus sandbox credential retry edge cases. (#29734, #29624, #29637)
Fixed stale TUI safety prompts and cancelled reviews that could leave MCP startup appearing busy. (#30490, #31189)
Improved recovery when exec servers are temporarily offline and prevented remote-control token refresh retry storms. (#30098, #30201)
Preserved trailing realtime transcript text and terminal rollout events during shutdown. (#29918, #30144)
Improved incremental WebSocket request success by ignoring response metadata during comparisons. (#30770)
Reduced installer failures from GitHub API rate limits by reusing release metadata. (#31056)

Documentation

Documented UUID7 thread and turn IDs, plus recommended remote-executor integration-test workflows. (#27714, #29790)

Chores

Updated OpenSSL, Hono, fast-uri, quick-xml, and crossbeam-epoch to address security advisories. (#29487, #29650, #30941, #31308)

Codex Remote reaches general availability

Thu, 25 Jun 2026 00:00:00 GMT

# Codex Remote reaches general availability Codex Remote has reached general availability. Use Codex from the ChatGPT mobile app to start or continue work on a connected Mac or Windows host, review progress, and approve actions from your phone. Remote Control now uses authenticated one-to-one QR pairing between each iOS or Android device and each host. Update the ChatGPT mobile app and Codex App to the latest versions before connecting. Connections used since June 8, 2026, remain paired; older inactive connections need to pair again. The new [DigitalOcean plugin](https://chatgpt.com/plugins/share/5dc672c7116c44ff92595d48e72df522) lets Codex provision a DigitalOcean Droplet, configure SSH access, and connect it to the Codex App as a remote workspace. See [Remote connections](/codex/remote-connections) for setup and troubleshooting.

GPT-5.5 and Codex app updates

Thu, 23 Apr 2026 00:00:00 GMT

# GPT-5.5 and Codex app updates [GPT-5.5 is now available in Codex](https://openai.com/index/introducing-gpt-5-5/) as OpenAI's newest frontier model for complex coding, computer use, knowledge work, and research workflows. #### GPT-5.5 in Codex GPT-5.5 is the recommended choice for most Codex tasks when it appears in your model picker. It's especially useful for implementation, refactors, debugging, testing, validation, and knowledge-work artifacts. To switch to GPT-5.5: - In the CLI, start a new thread with: ```bash codex --model gpt-5.5 ``` Or use `/model` during a session. - In the IDE extension, choose GPT-5.5 from the model selector in the composer. - In the Codex app, choose GPT-5.5 from the model selector in the composer. If you don't see GPT-5.5 yet, update the CLI, IDE extension, or Codex app to the latest version. During the rollout, continue using GPT-5.4 if GPT-5.5 is not yet available. #### Browser use in the Codex app The Codex app can now let Codex operate the in-app browser for local development servers and file-backed pages. Ask Codex to use the browser when it needs to click through a rendered UI, reproduce a visual bug, or verify a local fix inside the app. Browser use runs through the bundled Browser plugin. In settings, you can manage the plugin and review allowed or blocked websites. #### Automatic approval reviews Codex can route eligible approval prompts through an automatic reviewer agent before the request runs. When configured, the Codex app shows an automatic review item with the review status and risk level, so you can see whether the reviewer approved, denied, stopped, or timed out before deciding.

Codex can now help with more of your work

Thu, 16 Apr 2026 00:00:00 GMT

# Codex can now help with more of your work Codex is becoming a broader workspace for getting work done with AI. This update makes it easier to start work with less setup, verify what Codex is building, create richer outputs, and keep momentum across longer-running tasks. #### Verify more of your work The Codex app now includes an early [**in-app browser**](/codex/browser?surface=app). You can open local or public pages that don't require sign-in, comment directly on the rendered page, and ask Codex to address page-level feedback. [**Computer use**](/codex/computer-use) lets Codex operate macOS apps by seeing, clicking, and typing, which helps with native app testing, simulator flows, low-risk app settings, and GUI-only bugs. The feature isn't available in the European Economic Area, the United Kingdom, or Switzerland at launch. #### Start, follow, and steer work [**Chats**](/codex/projects#start-without-a-project) are threads you can start without choosing a project folder first. They're useful for research, writing, planning, analysis, source gathering, and tool-driven work that doesn't begin in a codebase. For work that needs a later check-in, [**thread automations**](/codex/automations#schedule-work-from-a-task) can wake up the same thread on a schedule while preserving the conversation context. Use them to check a long-running process, watch for updates, or continue a follow-up loop without starting from scratch. [**The task sidebar**](/codex/artifacts-viewer#follow-artifact-work) makes plans, sources, generated artifacts, and summaries easier to follow while Codex works. [**Context-aware suggestions**](/codex/app/settings#context-aware-suggestions) can also help you pick up relevant follow-ups when you start or return to Codex. #### Stronger for software development Codex now brings more of the **pull request workflow** into the app. You can inspect [**GitHub pull requests**](/codex/code-review?surface=app#app-pull-request-reviews) in the sidebar, review comments in the diff, review changed files, then ask Codex to explain feedback, make changes, check them, and keep the review moving. #### Review richer outputs The [**artifact viewer**](/codex/artifacts-viewer) can preview generated files such as PDF files, spreadsheets, documents, and presentations in the sidebar before you commit or share them. [**Memories**](/codex/customization/memories), where available, can also carry useful context from past tasks into future threads, including stable preferences, project conventions, and recurring work patterns. #### Other features - [Remote connections](/codex/remote-connections) - We're gradually rolling out SSH remote connections in alpha - Support for [multiple terminals](/codex/integrated-terminal) - macOS menu bar and [Windows system tray](/codex/windows/windows-app) support - [Multi-window support](/codex/reference/settings#keep-a-task-near-your-work) - [Intel Mac support](/codex/app) - [New plugins](/codex/plugins) - Improved thread and tool rendering

Codex model availability update

Tue, 07 Apr 2026 00:00:00 GMT

# Codex model availability update We're updating model availability for users who sign in with ChatGPT. Starting April 7, the model picker no longer shows `gpt-5.2-codex`, `gpt-5.1-codex-mini`, `gpt-5.1-codex-max`, `gpt-5.1-codex`, `gpt-5.1`, or `gpt-5`. On April 14, we'll remove those models from Codex for ChatGPT sign-in. Users can still choose from `gpt-5.4`, `gpt-5.4-mini`, `gpt-5.3-codex`, and `gpt-5.2`. ChatGPT Pro users can also choose `gpt-5.3-codex-spark`. To use another API-supported model in Codex, sign in with an API key or configure a model provider.

# Codex app #### Codex app for Windows The Codex app is now available on Windows. The app gives you one interface for working across projects, running parallel agent threads, and reviewing results in one place. The Codex app runs natively on Windows using PowerShell and a native Windows sandbox for bounded permissions, so you can use Codex on Windows without moving your workflow into WSL, onto a virtual machine, or by deactivating the sandbox. The Windows app includes the same core features as the rest of the Codex app: - [Skills](/codex/build-skills) to discover and extend Codex capabilities. - [Automations](/codex/automations) to run work in the background. - [Worktrees](/codex/environments/git-worktrees) to handle independent tasks in the same project. If you prefer to develop in WSL, you can also switch the Codex agent and the integrated terminal to run there. Download it from the [Microsoft Store](https://get.microsoft.com/installer/download/9PLM9XGG6VKS?cid=website_cta_psi) and sign in with your ChatGPT account or an API key. For setup and configuration details, see [Setup](/codex/windows/windows-app#download-the-chatgpt-desktop-app), [Use WSL with the Codex app](/codex/windows/windows-app#windows-subsystem-for-linux-wsl), and [Customize the app for your development setup](/codex/windows/windows-app#customize-for-your-dev-setup).

Check out the [Codex app documentation](/codex/app) for more.

Web search is now enabled by default

Wed, 28 Jan 2026 00:00:00 GMT

# Web search is now enabled by default Codex now enables web search for local tasks in the Codex CLI and IDE Extension. By default, Codex uses a web search cache, which is an OpenAI-maintained index of web results. Cached mode returns pre-indexed results instead of fetching live pages, while live mode fetches the most recent data from the web. If you are using `--yolo` or another [full access sandbox setting](/codex/agent-approvals-security), web search defaults to live results. To disable this behavior or switch modes, use the `web_search` configuration option: - `web_search = "cached"` (default; serves results from the web search cache) - `web_search = "live"` (fetches the most recent data from the web; same as `--search`) - `web_search = "disabled"` to remove the tool To learn more, check out the [configuration documentation](/codex/config-file/config-basic).

Team Config for shared configuration

Fri, 23 Jan 2026 00:00:00 GMT

# Team Config for shared configuration Team Config groups the files teams use to standardize Codex across repositories and machines. Use it to share: - `config.toml` defaults - `rules/` for command controls outside the sandbox - `skills/` for reusable workflows Codex loads these layers from `.codex/` folders in the current working directory, parent folders, and the repo root, plus user (`~/.codex/`) and system (`/etc/codex/`) locations. Higher-precedence locations override lower-precedence ones. Admins can still enforce constraints with `requirements.toml`, which overrides defaults regardless of location. Learn more in [Team Config](/codex/enterprise/admin-setup#step-4-standardize-local-configuration-with-team-config).

Custom prompts deprecated

Thu, 22 Jan 2026 00:00:00 GMT

# Custom prompts deprecated Custom prompts are now deprecated. Use [skills](/codex/build-skills) for reusable instructions and workflows instead.

Wed, 14 Jan 2026 00:00:00 GMT

# GPT-5.2-Codex API availability GPT-5.2-Codex is now available in the API and for users who sign into Codex with the API. To learn more about using GPT-5.2-Codex check out our [API documentation](https://platform.openai.com/docs/models/gpt-5.2-codex).

Agent skills in Codex

Fri, 19 Dec 2025 00:00:00 GMT

# Agent skills in Codex Codex now supports **agent skills**: reusable bundles of instructions (plus optional scripts and resources) that help Codex reliably complete specific tasks. Skills are available in both the Codex CLI and IDE extensions. You can invoke a skill explicitly by typing `$skill-name` (for example, `$skill-installer` or the experimental `$create-plan` skill after installing it), or let Codex select a skill automatically based on your prompt. Learn more in the [skills documentation](/codex/build-skills). #### Folder-based standard (agentskills.io) Following the open [agent skills specification](https://agentskills.io/specification), a skill is a folder with a required `SKILL.md` and optional supporting files: ```text my-skill/ SKILL.md # Required: instructions + metadata scripts/ # Optional: executable code references/ # Optional: documentation assets/ # Optional: templates, resources ``` #### Install skills per-user or per-repo You can install skills for just yourself in `~/.codex/skills`, or for everyone on a project by checking them into `.codex/skills` in the repository. Codex also ships with a few built-in system skills to get started, including `$skill-creator` and `$skill-installer`. The `$create-plan` skill is experimental and needs to be installed (for example: `$skill-installer install the create-plan skill from the .experimental folder`). #### Curated skills directory Codex ships with a [small curated set of skills](https://github.com/openai/skills) inspired by popular workflows at OpenAI. Install them with `$skill-installer`, and expect more over time.

Introducing GPT-5.2-Codex

Thu, 18 Dec 2025 00:00:00 GMT

# Introducing GPT-5.2-Codex [Today we are releasing GPT-5.2-Codex](https://openai.com/index/gpt-5-2-codex), the most advanced agentic coding model yet for complex, real-world software engineering. GPT-5.2-Codex is a version of [GPT-5.2](https://openai.com/index/introducing-gpt-5-2/) further optimized for agentic coding in Codex, including improvements on long-horizon work through context compaction, stronger performance on large code changes like refactors and migrations, improved performance in Windows environments, and significantly stronger cybersecurity capabilities. Starting today, the CLI and IDE Extension will default to `gpt-5.2-codex` for users who are signed in with ChatGPT. API access for the model will come soon. If you have a model specified in your [`config.toml` configuration file](/codex/local-config), you can instead try out `gpt-5.2-codex` for a new Codex CLI session using: ```bash codex --model gpt-5.2-codex ``` You can also use the `/model` slash command in the CLI. In the Codex IDE Extension you can select GPT-5.2-Codex from the dropdown menu. If you want to switch for all sessions, you can change your default model to `gpt-5.2-codex` by updating your `config.toml` [configuration file](/codex/local-config): ```toml model = "gpt-5.2-codex” ```

Usage and credits fixes

Mon, 24 Nov 2025 00:00:00 GMT

# Usage and credits fixes Minor updates to address a few issues with Codex usage and credits: - Adjusted all usage dashboards to show "limits remaining" for consistency. The CLI previously displayed "limits used." - Fixed an issue preventing users from buying credits if their ChatGPT subscription was purchased via iOS or Google Play. - Fixed an issue where the CLI could display stale usage information; it now refreshes without needing to send a message first. - Optimized the backend to help smooth out usage throughout the day, irrespective of overall Codex load or how traffic is routed. Before, users could get unlucky and hit a few cache misses in a row, leading to much less usage.

Introducing GPT-5.1-Codex-Max

Tue, 18 Nov 2025 00:00:00 GMT

# Introducing GPT-5.1-Codex-Max [Today we are releasing GPT-5.1-Codex-Max](https://openai.com/index/gpt-5-1-codex-max), our new frontier agentic coding model. GPT‑5.1-Codex-Max is built on an update to our foundational reasoning model, which is trained on agentic tasks across software engineering, math, research, and more. GPT‑5.1-Codex-Max is faster, more intelligent, and more token-efficient at every stage of the development cycle–and a new step towards becoming a reliable coding partner. Starting today, the CLI and IDE Extension will default to `gpt-5.1-codex-max` for users that are signed in with ChatGPT. API access for the model will come soon. For non-latency-sensitive tasks, we’ve also added a new Extra High (`xhigh`) reasoning effort, which lets the model think for an even longer period of time for a better answer. We still recommend medium as your daily driver for most tasks. If you have a model specified in your [`config.toml` configuration file](/codex/local-config), you can instead try out `gpt-5.1-codex-max` for a new Codex CLI session using: ```bash codex --model gpt-5.1-codex-max ``` You can also use the `/model` slash command in the CLI. In the Codex IDE Extension you can select GPT-5.1-Codex from the dropdown menu. If you want to switch for all sessions, you can change your default model to `gpt-5.1-codex-max` by updating your `config.toml` [configuration file](/codex/local-config): ```toml model = "gpt-5.1-codex-max” ```

The model is a smaller, more cost-effective, but less capable version of `gpt-5-codex` that provides approximately 4x more usage as part of your ChatGPT subscription. Starting today, the CLI and IDE Extension will automatically suggest switching to `gpt-5-codex-mini` when you reach 90% of your 5-hour usage limit, to help you work longer without interruptions. You can try the model for a new Codex CLI session using: ```bash codex --model gpt-5-codex-mini ``` You can also use the `/model` slash command in the CLI. In the Codex IDE Extension you can select GPT-5-Codex-Mini from the dropdown menu. Alternatively, you can change your default model to `gpt-5-codex-mini` by updating your `config.toml` [configuration file](/codex/local-config): ```toml model = "gpt-5-codex-mini” ```

Codex is now GA

Mon, 06 Oct 2025 00:00:00 GMT

# Codex is now GA Codex is now generally available with 3 new features — @Codex in Slack, Codex SDK, and new admin tools. #### @Codex in Slack ![](/images/codex/integrations/slack-example.png) You can now questions and assign tasks to Codex directly from Slack. See the [Slack guide](/codex/third-party/slack) to get started. #### Codex SDK Integrate the same agent that powers the Codex CLI inside your own tools and workflows with the Codex SDK in Typescript. With the new Codex GitHub Action, you can easily add Codex to CI/CD workflows. See the [Codex SDK guide](/codex/codex-sdk) to get started. ```ts const agent = new Codex(); const thread = await agent.startThread(); const result = await thread.run("Explore this repo"); console.log(result); const result2 = await thread.run("Propose changes"); console.log(result2); ``` #### New admin controls and analytics ![](/images/codex/enterprise/analytics.png) ChatGPT workspace admins can now edit or delete Codex Cloud environments. With managed config files, they can set safe defaults for CLI and IDE usage and monitor how Codex uses commands locally. New analytics dashboards help you track Codex usage and code review feedback. Learn more in the [enterprise admin guide.](/codex/enterprise/admin-setup) #### Availability and pricing updates The Slack integration and Codex SDK are available to developers on ChatGPT Plus, Pro, Business, Edu, and Enterprise plans starting today, while the new admin features will be available to Business, Edu, and Enterprise. Beginning October 20, Codex Cloud tasks will count toward your Codex usage. Review the [Codex pricing guide](/codex/pricing) for plan-specific details.

Mid August update

Thu, 21 Aug 2025 00:00:00 GMT

# Mid August update #### Image inputs ![](/images/codex/changelog/image_input.png) You can now attach images to your prompts in Codex web. This is great for asking Codex to implement frontend changes or follow up on whiteboarding sessions. #### Container caching ![](/images/codex/changelog/container_caching.png) Codex now caches containers to start new tasks and followups 90% faster, dropping the median start time from 48 seconds to 5 seconds. You can optionally configure a maintenance script to update the environment from its cached state to prepare for new tasks. See the docs for more. #### Automatic environment setup Now, environments without manual setup scripts automatically run the standard installation commands for common package managers like yarn, pnpm, npm, go mod, gradle, pip, poetry, uv, and cargo. This reduces test failures for new environments by 40%.
