Grok Bot vs ChatGPT Agent: Which AI Models Power Grok Bot And ChatGPT Work, And What The GoldieBench Scores Really Say

Grok Bot vs ChatGPT agent comes down to models in a way most comparisons skip: one tool lets you pick the model and the other never tells you which one ran.

First, the naming: OpenAI's ChatGPT agent article now says the agent is no longer available and sends users to ChatGPT Work.

Lower on that same article the old usage limits are still listed, but they apply to a tool that has been switched off.

So this page sets Grok Bot against ChatGPT Work and asks what the GoldieBench numbers can and can't tell you about each.

Every score below was read on live goldiebench.com pages on 5 November 2026, and each one names its page.

How each tool chooses its model

ChatGPT Work: you choose

OpenAI's Work and Codex help page lists GPT-6.1 Sol, GPT-6.1 Terra, GPT-6 Sol and GPT-6 Luna as models for Work and Codex, not for regular chat.

A model picker lets you leave it on Default, which blends models and reasoning levels on one slider, or pick a model and its reasoning level.

What you see depends on your plan, your workspace settings and the rollout.

Grok Bot: it chooses

The Grok Bot FAQ says Grok Bot picks the model for each task and has no model picker.

xAI doesn't say which model handles a given request, so no benchmark can tell you what a Bot ran.

The GoldieBench scores that bear on this pairing

Each task is one fixed prompt, one try, one HTML file, scored 0 to 10, as the methodology page explains.

Why none of these is the model inside either agent

The four Work models named by OpenAI don't appear on the GoldieBench model list.

GPT-5.6 Sol is the closest OpenAI model on the bench, benched as the flagship Sol at medium reasoning effort.

The Grok page tests xAI's Grok chat model, which is not Grok Bot.

Since Grok Bot doesn't reveal its model, the Grok row only tells you how one xAI model performed on these builds.

Read the table as background on the vendors' models, not as a score for either agent.

What GPT-5.6 Sol's 8.16 means for a Work user

On the GPT-5.6 Sol page, the model averages 8.16/10 across 50 tasks with 2 gold, 9 silver and 10 bronze medals.

Its page-type builds are the ones closest to Work's Sites: Landing Page 8.7, Webos Page 8.4 and Aipbpromo Page 8.3.

If your Work jobs are mostly Sites, dashboards and forms, those three rows matter more than the game scores.

Work's own model picker is where you act on that, by trying a stronger model on the job that keeps coming back wrong.

What Grok's 8.09 means for a Grok Bot user

On the Grok page, Grok averages 8.09/10 over 47 demos, 43 of them scored, with 5 gold, 1 silver and 1 bronze.

It scores 9.0 with gold on both Landing Page and Webos Page, and 7.0 on Aipbpromo Page.

The same page also says Grok is currently unranked and that standalone bench scoring is pending, which sits awkwardly next to an average.

I'd treat that as an open conflict on the site and lean on the head-to-head below instead.

For a Grok Bot owner none of this is actionable, because there is no picker to change.

The head-to-head: GPT-5.6 Sol vs Grok

The GPT-5.6 Sol vs Grok page gives the verdict as GPT-5.6 Sol winning 28–14 with 1 tie on shared prompts.

Grok's biggest single win there is the Voxel visual, 8.5 against 3.5.

Sol's wins include the Aurora and Matrix visuals and the Aipbpromo page.

That's a model-versus-model result on one-shot HTML builds; it says nothing about routines, approvals or browser work.

What the bench can't measure in this comparison

• How well an agent runs a scheduled or event task. Work's Scheduled tasks and Grok Bot's routines sit outside the bench.
• How safely it handles a sign-in. Work's cloud browser uses a secure form the model can't see; Grok Bot fills logins from Vault or a Secure Form.
• How the computer is shared. All your Bots use one cloud computer and each Bot gets its own screen, per the computer docs.
• Multi-step deliverables such as a full deck plus spreadsheet plus report from one brief.

How to test models on your own Work jobs

1. Pick one Work job you run often, such as a weekly report or a form Site.
2. Run it once on Default and save the result.
3. Open the model picker, choose a specific model and reasoning level, and run the same brief again.
4. Compare the two drafts against the checks you set in the brief, not against a benchmark.
5. Keep the setting that passes your checks, and set it as the starting model if you're a workspace admin.

OpenAI's help page says workspace owners can set a starting model, reasoning level and speed for Work and Codex under Workspace settings, Models.

Verdict by job type

Pick ChatGPT Work if model control matters to you, because it's the only one of the two that offers it.

Pick Grok Bot if you'd rather judge the agent by its finished work and leave the routing to xAI.

Small-business examples, step by step

A wedding photographer on ChatGPT Work

1. She uploads her package list and asks Work for a pricing-enquiry Site with a request form.
2. Work builds the Site and lists checks to run before sharing.
3. If the layout keeps missing the brief, she switches the model in the picker and asks again.

A physiotherapy clinic on Grok Bot

1. The clinic creates a Bot called Recall that owns patient follow-up reminders.
2. A routine runs each weekday, checks the appointment sheet and drafts reminder emails from the Bot's own address.
3. Routine emails wait as drafts, so reception reviews and sends them.

Plans and where to read more

Grok Bot is in Premium, Super and Ultra on The X Subscription; Plus doesn't include it.
