The Ledger

October 16 release follows September 29's planned Slides announcement. Rolling out to eligible Pro, Business, and Enterprise users with Space access on web and desktop. Web exports support PowerPoint, PDF, and Google Slides; desktop can open decks in installed PowerPoint or Keynote. The general Space guide still describes Pages, so it is not used as launch evidence.

October 16 announcement. Rolling out to eligible Pro users; managed-workspace availability depends on settings and rollout eligibility. This concerns the Pro model in Chat, not a claim that all Chat models or accounts gain parallel agents.

October 16 release-note bundle. OpenAI directs users to real-time Google Drive, SharePoint, and Microsoft Teams apps. Controls appear under each app's Safety & Security Controls; provider permissions remain applicable. Three linked setup guides returned 404 during review; no unverified configuration details or blanket Edu eligibility inferred.

Dated October 16 in Enterprise/Edu release notes. Covers Sign in with ChatGPT, connected-app access, and Ads data. Existing policies and approvals persist. Updated console applies to eligible Enterprise and Edu tenants; member consent and provider permissions still apply. Material governance expansion of earlier sign-in and connected-app coverage, not automatic authorization of apps.

Date uses the week-ending October 16 recap for October 12–16; individual release day is unspecified. Rolling out with ChatGPT for iOS 1.2026.279 and requires existing dot access. A saved shortcut can use the Action button on supported iPhones. Material expansion of September 29 dots and October 9 mobile setup; not broader plan or regional availability.

October 15 announcement in ChatGPT release notes. New voice options cover French, German, Hindi, Japanese, Korean, Mexican Spanish, and Bubbie in English; availability varies by region and account. Model access depends on plan, workspace settings, client, and rollout. Free and Go use Quip; paid-plan access and limits vary. This expands earlier Live Voice coverage; no universal rollout-completion claim.

Grouped October 15 Enterprise Sites update, expanding earlier Sites coverage. Admin preview and tunnels are rolling out to eligible Enterprise workspaces; public publishing remains off by default and requires separate enablement. Existing Sites are not automatically migrated. Residency outside US/EU does not currently extend to Sites hosting/storage, and hosting residency is separate from inference residency. Tunnels require workspace permissions, an IT-run client, and the private service's authentication; public Sites using tunnels need additional authorization. Dedicated guides: https://help.openai.com/en/articles/20001338-managing-chatgpt-sites-for-your-workspace and https://help.openai.com/en/articles/20001606-connecting-chatgpt-sites-to-private-services-with-tunnels . No general Edu or universal Enterprise availability inferred.

Codex CLI 0.163.0 dated October 15. Interrupting a turn also stops active Code Mode cells and their nested tool calls. Material client expansion beyond October 8 desktop steering; not an API-only feature. Other configuration, shortcut, maintenance, and bug-fix changes in this release are not separate Ledger entries.

October 15 dated ChatGPT release-note change, corroborated by the Sites guide. This expands earlier Sites coverage, not unlimited hosting or storage. Building and editing count toward Codex usage; reaching a shared limit can prevent creating another Site.

Applications opened October 15; applying does not grant immediate access. Limited to labs at US universities. A principal investigator or lab lead applies and manages approved members. Labs covered by an OpenAI Enterprise agreement use their institution's access process instead. Setup requires a payment card; normal usage limits continue. This is an access offer, not a general release of GPT-Rosalind or an API offer.

October 15 Business and Enterprise/Edu release notes establish the date. Available for Business, Enterprise, Healthcare, and Edu workspaces. Role-specific changes require RBAC. Review dependencies and each plugin's saved result; required-app access and provider permissions still apply. Material expansion of October 1 plugin management and October 8 role-based controls, not a change to connected-provider authorization.

Effective October 14, 2026 at noon PDT (19:00 UTC), explicitly documented in the October 14 changelog and current Models guidance. Material follow-through on September 14's planned retirement. This entry confirms Codex only, not completion in regular Chat or ChatGPT Work. Plus, Pro, Business, Enterprise and Edu users should choose GPT-6.1 Sol when available; Free and Go users should choose GPT-6 Luna in the desktop app when available. Update saved model choices and automations. OpenAI API and API-key-authenticated Codex sessions are unaffected.

Material expansion of the September 29 dots launch. Date uses the October 9 weekly update endpoint for OpenAI's October 5–9 recap; the source does not specify individual release days. Mobile setup supports iOS and Android in updated apps, with an option to open directly to the dot conversation. Codex delegation can use ChatGPT chats, Codex threads, and automations as context. Existing gradual rollout, eligible plan and region limits, workspace controls, connected-app permissions, and optional local-computer access still apply; this does not establish universal access.

Beta for adults aged 18 and older on personal ChatGPT Pro plans in supported regions, using the latest Codex desktop app. It supports local and SSH threads with GPT-6 Astra or GPT-6.1 Sol and is on by default for eligible users. Predictions do not send automatically and can be disabled in General settings. During the beta, generating predictions does not count toward Codex usage limits or consume credits; sent messages follow normal usage and billing. It is not available in Chat, on the web, or on other plans.

Admins can set the workspace default for each plugin to Available, Install, or Disabled, while custom roles can inherit the default or use their own setting. Required-app permissions, approval rules, action settings, and provider authorization continue to apply. This extends the October 1 Admin-console plugin-management release with role-level controls and explicit Edu availability.

Available on Pro 500 and in eligible Enterprise and Edu workspaces. Enterprise access is off by default and must be enabled by a workspace owner. Pro 500 usage draws from the included allowance at 8 times the Standard rate, then from credits at 6 times the Standard credit rate; eligible Enterprise and Edu usage is charged to workspace credits. GPT-6.1 Sol Ultrafast supports inference residency in the United States and Europe (EEA and Switzerland). This materially expands the September 29 Ultrafast entry, which covered GPT-6 Astra and Pro 500.

Rolling out in the ChatGPT desktop app. Users can steer the current run to correct an approach, add information, or change direction, and can choose in Settings whether follow-up messages steer the current run or wait for the next one.

Global rollout began October 7 for Plus, Pro, Business, and Enterprise, with Free and Go expansion announced to start October 8. Paid tiers use GPT-6 Sol; Free and Go are announced to use GPT-6 Luna. Access is gradual and subject to workspace permissions and supported updated clients. Intelligent UI supports Instant through Extra High where the plan permits; Pro effort uses Astra and does not support Intelligent UI. It is unavailable in Work and Voice; this release does not change Work or Codex models. Older desktop apps do not support the new UI. Current model guidance still contains GPT-5.6 Luna references for Free/Go, so the announced October 8 expansion is not treated as independently confirmed universal availability.

Announcement date: October 7. Coming soon, with no exact launch date or subscription eligibility specified. Initial US experience is designed for grades 10–12 students planning to attend a four-year college. Expansion to more countries and other education pathways is planned. This announcement does not establish that College Planner is available now. Previously announced flashcards and iOS multi-page scanning are not counted again.

Released October 6. Audio uploads are available on paid ChatGPT subscriptions and workspaces, including Enterprise, but not on the Free plan. Availability may vary by workspace settings, region, client version, and selected model. Supported audio files can be up to 512 MB. OpenAI cautions that transcripts may contain errors, speaker identification may be unreliable, and performance can vary across languages; very long recordings may time out.

Announcement date: October 5. Rollout is planned over the coming weeks for eligible users across all ChatGPT plans in the European Union; it is not a global default at launch. The textGrain signal changes word-choice probabilities and is not visible. Detection is imperfect and does not identify the user, measure human contribution, establish ownership or responsibility, or verify accuracy. Detector access begins with approved researchers and expert organizations.

Announcement date: October 5. Testing is planned to begin later in October in the United States with an initial group of advertisers. OpenAI says ads will not influence ChatGPT's answers. Under the current ChatGPT Ads policy, ads may appear on Free and Go accounts; Plus, Pro, Business, Enterprise, and Edu accounts and users identified as under 18 do not receive ads. The announcement does not give an exact launch date or identify which eligible users will see this specific test.

Rolling out on web, iOS, and Android. Announcement date: October 2; access may arrive gradually.

OpenAI announcement dated October 1. Checkout takes place at Safeway; expansion to other Albertsons grocery brands is planned. The announcement does not specify ChatGPT plan eligibility or full geographic availability.

Available to workspace owners and admins on ChatGPT Business and Enterprise plans. Select the ChatGPT workspace in Admin console, then open Plugins or Marketplaces. Apps remain available through Workspace settings > Apps or Manage Legacy Apps, and existing permissions and app access controls still apply. The dated release notes do not establish this launch for Edu.

Rolling out on iOS. Open the camera menu and select Scan.

Material access development following the September 17 Word launch. Workspace administrators can still disable Word access, and Microsoft 365 administrators must allow the add-in. Date is the documented effective date; default enablement does not guarantee access for every member.

Available on web and mobile. Reference photos can be changed or deleted in Personalization settings.

This model is separate from regular Chat. Availability depends on plan and workspace settings; Enterprise and Edu administrators enable access.

September 29 launch documented in ChatGPT, Business, and Enterprise release notes. Tasks can continue while the computer is asleep and can be started or continued from desktop, web, or mobile. Availability depends on plan and workspace controls; authorized Enterprise members can share environments.

Gradual rollout for eligible adults on Pro and Business Premium. Pro excludes the EEA, Switzerland, and UK at launch; Enterprise beta requires admin enablement.

Among Pro tiers, Ultrafast requires Pro 500. Credits on Pro 100 or Pro 200 do not unlock it. Web subscriptions are available at launch.

Available to eligible Pro, Business, and Enterprise accounts. Space replaces Library where enabled; Projects remain separate. Mobile supports reading and sharing, but not Page editing.

The provider account determines data and action access. Sharing a plugin and granting app-connection access are separate. Also documented in Enterprise release notes.

September 29 Business and Enterprise announcement. The dedicated product page also lists Edu. Administrators must install and configure the service and approved tools; connected-account permissions determine access. Replies in shared conversations are visible to participants.

September 29 launch announcement. GitHub review is generally available; GitLab merge-request support is in preview. Connected repository permissions apply. Automatic cloud reviews require separate configuration; discussing a review does not itself post feedback or approve a pull request.

September 29 announcement. Supports on-demand and scheduled scans plus monitoring new commits. Available to eligible Pro, Business, Enterprise, and Edu users on desktop and web, subject to repository permissions, cloud setup, and billing. Daybreak Blue access is confined to Security Cloud.

September 29 announcement. Requires a supporting plugin using MCP 2.0. Documented for Work on web, cloud Work in the desktop app, and dots. Connected-account access and workspace controls apply; users choose what to monitor and what should happen.

Limited preview with participating integrations. Credit use requires separate permission; partner charges may still apply.

September 29 announcement. Beta in the macOS desktop app for all Pro and Business plans; Enterprise is limited alpha access, not general availability. Space and plugin permissions apply. Audio is deleted after notes finish processing and cannot be replayed.

September 29 announcement. Applicable app connections and workspace permissions remain required. Developer documentation says web extensions for Free and Go are coming soon, and composer mentions are desktop-only; do not read the broader launch announcement as universal immediate access.

Qualifying subscriptions active between September 22 and 10 a.m. Pacific on September 29 retain the earlier allowance through October 29 while active. Price remains unchanged.

Editing starts in a desktop browser. Availability and sharing remain subject to account, regional, and workspace controls.

Identity sign-in does not grant access to chats or memory. Additional permissions and organizational controls apply separately.

September 29 announcement for Business and Enterprise workspaces. Tasks run through a team's service account and approved workspace connections, on a schedule or supported trigger. Team membership, action permissions, and provider access apply separately. This is distinct from configuring team connections.

September 29 announcement. Teams are separate from workspace administration and groups. Membership does not share personal chats or app connections and does not override content permissions. Team app connections already have a separate Ledger entry.

September 29 connected-app expansion, separate from the earlier Ledger entry on published-site editing and schedules. Organization approval and per-plugin Allow use in Sites are required; access is off by default. Visitor authorization permits read-only use while visiting and cannot supply access for background scheduled tasks.

Sharing and showcasing are available on web and desktop. Business profile visibility follows admin settings; Enterprise sharing is coming later.

Announcement date: September 29. Planned for Pro, Business, and Enterprise in the coming weeks; no exact launch date stated. Space documentation still describes Slides as coming soon. This is separate from the existing PowerPoint add-in and the Pages launch.

September 29 announcement. OpenAI and participating partners manage the initial program directly; eligibility depends on the customer, product, and purchase. Customers contract with and receive invoices from the partner. There is no self-service checkout.

September 28 announcement in ChatGPT release notes. Health rolls out gradually to eligible U.S. users aged 18 or older on Free, Go, Plus, and Pro, on web and iOS. Apple Health connections require an iPhone; source availability varies.

On web, open Settings, then Security and login, then Security history. Location and device details may be approximate or unavailable.

Web, iOS, and Android; Voice in Work requires both Voice and Work access. Existing permissions apply, and sensitive approvals use on-screen controls.

Available models and reasoning levels depend on the account and workspace. GPT-6.1 Sol is a distinct later rollout on September 29.

Launch documented September 22. Available on web and mobile for all ChatGPT plans.

Initial rollout: U.S. Plus and Pro on web, iOS, and Android. Reports update monthly. The October 2 Finances expansion is a separate availability development.

Rolling out to signed-in Free, Go, Plus, and Pro users. Controls remain in Settings; options vary by plan, region, and workspace.

Available across ChatGPT plans, including Free; token limits apply. Workspace and Microsoft 365 admin controls can restrict access.

Announcement dated September 14; added after discovering a continuing upcoming retirement missing from the initial selection. Retirement remains planned, not completed. The OpenAI API is unaffected. Review defaults, saved model settings, custom agents, and scheduled tasks that select GPT-5.5, and choose an available replacement.

Planned retirement: December 11, 2026; approved Enterprise deferrals use February 11, 2027. Follow account notices. Custom actions do not migrate automatically.

Requires appropriate source connections and permissions. Workspace administrators may need to enable the plugin and configure data-source access.

Templates are not available in Work at launch. Existing image-generation limits remain in effect. Mobile and account availability vary by feature.

Covers public research and healthcare data, not patient charts. Install the plugin and connect supported apps; do not put protected health information in searches.
