OpenAI retired agent mode in August 2026 and moved multi-step work into ChatGPT Work with a cloud browser. If you came here from a dead agent-mode tab, this is the honest read.

Built from their own published pricing and documentation, checked in September 2026.
A browser agent on our servers with a Chrome profile of your own, and a toolbelt that writes the files on the server.
The strongest general model, with a cloud browser attached to it.
The lines that actually change the day, not a feature count.
| Katteb | ChatGPT | |
|---|---|---|
| What it is | A browser agent with its own real Chrome profile on our servers, plus a toolbelt for files, data and media. | A chat assistant with a cloud browser. Agent mode itself was retired in August 2026. |
| Where the browser runs | On Katteb's servers, always on, one dedicated profile per account. | OpenAI's own cloud browser. |
| Your signed-in accounts | You sign in once inside your own agent browser and the session stays. | You sign in inside their browser. Driving a logged-in session and handing control back mid-task is not what ChatGPT Work covers. |
| Exit IP address | A static ISP address tied to your host, the same one on every run. | OpenAI's datacentre address. |
| CAPTCHA | Solved inside the run. | A known failure point while agent mode existed. |
| Price before you run it | The plan card shows the hold (200 credits) before you press Run. | Bundled in the subscription and metered as a monthly allowance of agent messages. |
| A task that fails | Not charged at all, and the hold comes straight back. | Counts against that allowance. |
| Ceiling on one task | 1,500 credits a task on the entry plan, and we absorb the rest. | Agent mode allowed 40 tasks a month on Plus and 400 on Pro. |
| Scheduling | Daily, weekly, or only when you click. | Scheduled prompts, yes. A scheduled signed-in browser session, no. |
| Files it produces | PowerPoint with real charts, PDF, CSV, images, video, music, and voice notes in your own recorded voice. | Documents, spreadsheets, slides, code, images. |
| Where you talk to it | Web, an installable app, Telegram and Slack. | Web, desktop, mobile. |
| Entry price | $19 a month, agents included. | From $20 a month on Plus. |

Not features we counted. Three decisions in the architecture.
Your agent works in its own Chrome profile on our server, from a static IP, and stays signed in between one task and the next. The others either open a fresh sandbox per task and inject your session into it, or drive the browser on your own laptop, which then has to be awake. A task that runs on LinkedIn at 3am needs a steady identity, not a new sandbox.
A task holds 200 credits and settles at what it really cost, and a task that fails is charged nothing. The rest of this category bills from a credit pool that drains whether the task worked or not, with no budget stop to catch it.
Send a message while a task is running and it is delivered to the agent mid-flight rather than queued for the next one. When it hits a login wall or a real decision it stops and asks you instead of guessing. Press Stop and it wraps up, hands you the report and the files it already made, and charges only for the part that ran.
The loudest complaint in this whole category is that the price only appears after it is gone. Here is the entire policy.
Before it runs
It holds 200 credits, then you pay what the run really cost.
If it fails
You are charged nothing. Stop it halfway and you pay for the part that ran.
The ceiling
1,500 credits a task on the entry plan, and we absorb the rest.
OpenAI's help centre marked it as no longer available in August 2026 and pointed people at ChatGPT Work for multi-step tasks and at the cloud browser for browser workflows. Plenty of workflows people had built on it stopped working, which is why comparison pages like this one exist.
Not for chatting. Katteb Chat carries the leading models, including OpenAI's, so you do not lose the model. What Katteb adds is the part ChatGPT does not do: a persistent browser that stays signed in to your accounts and finishes work on a schedule.
Not reliably, and not unattended. It browses from its own datacentre in a session you opened, with no persistent profile and a documented CAPTCHA problem. Katteb was built for that specific job: your profile, your static address, a solver in the loop.
Over a hundred, including GPT, Claude and Gemini, priced per message from one balance. You pick the model per conversation, and the agent runs on the model we have measured as best for browser work.
The same lines, against other platforms.
A cloud agent on its own virtual machine, with an extension that can drive the browser on your laptop.
An all-in-one super agent for research, slides, sheets and outbound calls, with its own AI browser.
An agent builder for business workflows: inbox, calendar, meetings and a hundred connected apps.
Google's personal agent, bundled with Google AI Pro, driving the Chrome on your own computer.
Agents inside the automation platform that connects seven thousand apps.
Every plan includes the agents, from $19 a month. A free account opens the whole model catalogue to try in chat, and an agent run starts when a plan does.
