ChatGPT Business Release Notes

ChatGPT Connectors for Business Workspaces

ChatGPT Business workspaces can now use ChatGPT connectors for Aha!, Asana, ClickUp, GitLab Issues, Help Scout, Teamwork.com, and Zoho Desk. These connectors deliver faster, higher-quality answers–especially for knowledge-heavy prompts like strategy summaries, policy lookups, and internal research.

For Business workspaces, connectors are enabled by default—though Admins and Owners can disable specific connectors at any time from their Workspace connectors settings. Individual users can connect enabled connectors they want to use from Settings > Apps & Connectors. Once enabled, ChatGPT will automatically reference the indexed content when relevant. Learn more about how to use connectors here.

Company knowledge

Company knowledge lets ChatGPT use your organization’s context from your connected apps to give answers specific to your company and projects, with clear citations and links back to the original sources. It works across supported connectors like Slack, SharePoint, Google Drive, GitHub, HubSpot, Asana, and more, and respects each user’s existing permissions.

To get started, open a chat, select company knowledge under the message composer, and ask your question; ChatGPT will search your connected tools and show cited results. Learn more in our help center article on company knowledge for ChatGPT.

MCP support with developer mode

We’re rolling out full Model Context Protocol (MCP) support with developer mode so your organization can build, test, and publish MCP-powered connectors with read/write capabilities that let ChatGPT take action in your tools. Kick off workflows, create project management tasks, update your CRM, or combine connectors for more complex orchestrations.

Admins can review and publish connectors to the workspace. Build your own MCP connector, or upload trusted third party connectors.

Learn more in our Help Center article.

What’s New in Workspace

General tab updates

We’ve updated Workspace settings to make administration clearer and faster. A new General tab now centralizes workspace customization (name, logo, appearance, and workspace-wide instructions) and adds an AI policy modal you can configure to remind users of your organization’s AI policies on a recurring basis.

Identity & access changes

We’ve also streamlined navigation by combining Identity & provisioning with IP allowlists into a new Identity & access tab, and by renaming Settings & permissions to Permissions & roles.

We’re rolling out two new ways to bring Slack and ChatGPT together: a connector that brings your Slack context into ChatGPT, and a ChatGPT app for Slack – an integration that enables you to chat with ChatGPT from inside Slack.

With the ChatGPT app for Slack, you can chat one-on-one with ChatGPT in a dedicated Slack sidebar – a space to ask questions, summarize long threads into action items, draft replies, and search messages and files you already have access to. Chats you start in Slack also appear in your ChatGPT sidebar, so it’s easy to pick up later from web or mobile. Semantic search is supported for Slack customers with AI enabled on Business+ or Enterprise+ plans; all other plans use keyword search.

With the ChatGPT connector for Slack, you can securely bring in context from your Slack channels and DMs, making responses more helpful Available in chat, Deep Research, and Agent Mode. The connector is enabled by default for Business customers, and users can enable from Settings > Apps & Connectors.

Both app and connector are available to Plus, Pro, Business and Enterprise/Edu customers. Additionally, the ChatGPT app for Slack requires a paid Slack account; availability and workspace installation may depend on your Slack workspace settings.

Installing the app requires the connector to be enabled for your account.

Visit the ChatGPT app for Slack page to get started with installation.

We additionally added the Intercom synced connector, which allows you access and interact with your Intercom data—including conversations, tickets, and help center content.

Codex capabilities rollout

We’re rolling out new Codex capabilities to help teams work and build better:
Codex now works in Slack, and supports programmatic control through the Codex SDK. We’ve also added new admin controls and analytics so workspace admins can manage Codex Cloud environments, set safe defaults for CLI/IDE usage, and monitor usage with improved dashboards. Additionally, Codex rates have been updated.

For more information, review our Help Center article on Codex, and the Codex developer documentation.

You can now choose from four distinct personalities or use the Default personality in your Customize ChatGPT settings

Default is the standard ChatGPT style: clear, neutral, and adaptable. The other personalities each have their own style and tone, described below.

Cynic

• Sarcastic and dry, delivers blunt help with wit. Often teases, but provides direct, practical answers when it matters.

Robot

• Precise, efficient, and emotionless, delivering direct answers without extra words.

Listener

• Warm and laid-back, reflecting your thoughts back with calm clarity and light wit.

Nerd

• Playful and curious, explaining concepts clearly while celebrating knowledge and discovery.

Please note that these personalities will not apply to Voice mode.

GPT-5 Legacy Model Retirement

We will enable Team users to continue to access legacy mode - learn more.

When GPT-5 launches, several older models will be retired, including:

• GPT-4o
• GPT-4.1
• GPT-4.5
• GPT-4.1-mini
• o4-mini
• o4-mini-high
• o3
• o3-pro

If you open a conversation that used one of these models, ChatGPT will automatically switch it to the closest GPT-5 equivalent. Chats with 4o, 4.1, 4.5, 4.1-mini, o4-mini, or o4-mini-high will open in GPT-5, chats with o3 will open in GPT-5-Thinking, and chats with o3-Pro will open in GPT-5-Pro (available only on Pro and Team).

Please note that Voice mode is still powered by GPT-4o.
