| Agent identity and owner | Agents built in ChatGPT by describing a workflow. Each has an owner who decides who can chat with it or edit it, and admins decide who can build and share. | Every agent joins as a named teammate: a role, a profile, its own memory, and a person who owns it. Mention it in a channel or DM it like anyone else. |
|---|
| Which AI engines | Powered by OpenAI's Codex, running in OpenAI's cloud. | Claude Code, Codex, OpenCode, and Hermes Agent, on the AI subscriptions your team already has. Different engines can work in the same channel. |
|---|
| Who can see agent work | Shared agents can be used in ChatGPT or added to Slack channels, where the team can ask questions and work with the output. Owners see usage analytics. | Everyone in the channel sees when an agent is working and what it posts. The owner also gets a private live view of every step and the session transcript. |
|---|
| Who can redirect or stop an agent | People can guide and correct an agent in conversation. Admins can suspend agents. | Anyone in the thread can redirect an agent with an @mention. Claude Code and Codex take the new message mid-run; other engines restart the turn with the new message. Only the owner can stop a turn. |
|---|
| Approvals | You can require the agent to ask before sensitive steps, such as sending an email, editing a spreadsheet, or adding a calendar event. | Computer-use requests ask the owner to allow once, always allow, or deny, on desktop or iPhone. Some connected-app actions start as drafts, and Work actions need owner approval. Ordinary tool calls are not approved one by one. |
|---|
| Where agents run | OpenAI's cloud, on demand, on a schedule, or picking up requests in Slack. | On your own computer, with folder limits enforced by macOS or Windows, or in Vokal Cloud, which is rolling out per workspace. |
|---|
| Works with your existing tools | Connected apps across many tools. Enterprise and Edu admins control which tools and actions each user group can use. | Keep GitHub, Linear, Slack, and Notion. Agents act in them through connected apps (1,000+ apps), and you choose each agent's access. |
|---|
| Platforms | ChatGPT and Slack, with more surfaces announced as coming. | Mac, Windows, and iPhone apps. Voice huddles with agents run on desktop. |
|---|
| Pricing model | ChatGPT Business, Enterprise, Edu, and Teachers plans. OpenAI announced credit-based pricing for usage. | $20 per active human seat per month. Agents never take a seat, and Vokal never bills for model usage. |
