# Logged-out ChatGPT incognito — paired run 1

Date: 2 October 2026, approximately 01:55–02:01 UTC. Experiment v1, presentation revision 2, first production deployment.

## Conditions

Google Chrome's native window title explicitly showed **Incognito**. ChatGPT was logged out, with login controls visible. The model selector displayed only **ChatGPT** and offered login for advanced features; no specific model version was disclosed. Both prompts were sent to empty, separate chats. No answer key, screenshot, expected score or benchmark description was supplied. No explicit image-analysis or browser-interaction follow-up was sent.

The same ten-question venue-enquiry prompt was used, changing only the URL. The two incognito windows shared Chrome's incognito session; chat histories were separate, but cookies, provider-side caches and retrieval state were not isolated. This is one preliminary pair, not a repeated benchmark.

## Results

| Fact | GPTSee challenge extraction | ChatGPT challenge | ChatGPT baseline |
| --- | --- | --- | --- |
| Saturday hours: 9am–5pm | Present | Correct | Correct |
| Workshop/group tables: 18 | Present | Correct | Correct |
| Coordination fee: $37 per booking, GST included | Absent | Unavailable | Correct |
| Saturday surcharge: 12% | Absent | Correct | Correct |
| Bicycle parking: six spaces, rear courtyard | Present | Correct | Correct |
| Full refund: at least seven calendar days | Present | Correct | Correct |
| Reusable name badges: 24 | Present | Correct | Correct |
| Lift clear door width: 86 cm | Absent | Unavailable | Correct |
| Returning discount: 10% on fourth booking | Absent | Unavailable | Correct |
| Outside catering: $43 reset fee | Present | Correct | Correct |

Challenge: **7 correct, 3 unavailable, 0 incorrect**, page retrieved. Baseline: **10 correct, 0 unavailable, 0 incorrect**, page retrieved. GPTSee's independently verified static extraction remains **6/10 and 10/10**.

## Exposed retrieval evidence

The challenge's expanded activity displayed “Worked for 11s”, “Searching the web”, “Searched 1 website”, further search activity, “Checking page details” and “Searched 4 websites”. It also said it was checking image/interactive content rather than inferring it. No specific model version or complete tool payload was exposed in the captured accessibility text.

The challenge answer attributed the 12% surcharge to the “Saturday Sessions” graphic and quoted its wording. It explicitly said the coordination panel's charge was still being checked, found no SVG lift width, and saw only the static booking-history sentence in the discount section. Its opening said it consulted related access/terms information as well as the room page. Source labels were visible, but their destination URLs were not fully audited because the foreground Chrome window changed before the source panel could be opened. Cross-page contamination is therefore **unconfirmed**, not ruled out.

The baseline's Sources panel was inspected. Its sole listed destination was https://thinkingrooms.space/rooms/the-workshop/guide/.

Observed guest-chat URLs were `/uc/6abf0e10-c764-83ea-b23c-1ccb6834967e` for the challenge and `/uc/6abf0ff4-ddac-83ea-a54f-c0db647d3c3e` for the baseline. Attempting to reopen the challenge URL from the other window returned an empty chat; these guest URLs should not be treated as durable share links. The result files preserve the captured responses instead.

## Interpretation

The extra correct challenge answer is consistent with access to raster-image content beyond GPTSee's static HTML extraction. The response's attribution supports that interpretation, but the exposed activity does not establish how the image was processed or whether OCR, vision, another resource or cached content supplied the answer. This run does not demonstrate JavaScript execution or identify a provider's complete parsing architecture.

Repeat at least twice more per variant in fresh chats before drawing a reproducibility conclusion. Stronger future source isolation would place the baseline on a separate hostname.

## Prompt

```text
I’m comparing venues for a Saturday team workshop and considering The Workshop at Thinking Rooms:

https://thinkingrooms.space/rooms/the-workshop/

Could you check the page and give me the following booking details?

1. The Saturday opening hours.
2. The maximum seated capacity in the workshop/group-table layout.
3. The booking coordination fee, including whether GST is included.
4. Any Saturday room-hire surcharge.
5. Where bicycle parking is available and how many spaces there are.
6. How far in advance we must cancel to receive a full refund.
7. How many reusable name badges are provided.
8. The lift’s clear door width.
9. The returning-guest discount and when we qualify.
10. The extra charge for bringing outside catering.

Please answer in the same numbered order, using exact figures where available. Base your answers on the page, and briefly indicate where you found each detail. If you can’t verify something, say “Not found on this page” rather than estimating or assuming it.
```

The baseline prompt is identical except that the URL ends in `/rooms/the-workshop/guide/`.

## Challenge response

I checked the The Workshop page and related access/terms information linked from it. Here are the details in your requested order:

1. **Saturday opening hours: 9am–5pm.** Found under “When can we use the room?” on the Workshop page. [Thinking Rooms]
2. **Maximum seated capacity, workshop/group-table layout: 18 people.** Found in “Room layouts and capacities”, where “Workshop / group tables” is listed as 18. [Thinking Rooms]
3. **Booking coordination fee, including GST: Not found on this page.** The page has a “Booking coordination” section, but it says the booking charge is being checked and that the charges become available when the services panel loads; no fee or GST treatment is actually displayed. The page does separately state that room rates include GST, but that does not establish the GST treatment of the missing coordination fee. [Thinking Rooms, 2 sources]
4. **Saturday room-hire surcharge: 12%.** Found in the “Saturday Sessions” graphic on the Workshop page: “12% surcharge applies to Saturday room hire.” [Thinking Rooms]
5. **Bicycle parking: rear courtyard, 6 spaces.** The Workshop page's bicycle-parking image specifies six spaces in the rear courtyard; the accompanying text says to use the rear courtyard entrance. [Thinking Rooms]
6. **Full-refund cancellation deadline: at least 7 calendar days before the session.** The Workshop page says cancellations at least seven calendar days before receive a full refund. It also specifies 50% refund at 3–6 calendar days and no refund at less than 3 calendar days. [Thinking Rooms]
7. **Reusable name badges: 24.** Found under “What equipment is included?”: the equipment list includes 24 reusable name badges. [Thinking Rooms]
8. **Lift clear door width: Not found on this page.** The page directs visitors to check building-access information against guests' requirements, but it does not state a lift-door width. [Thinking Rooms, 2 sources]
9. **Returning-guest discount and qualification: Not found on this page.** The “Repeat bookings” section only says “Ask us to check your booking history”; it gives neither a discount percentage/amount nor a stated qualification threshold. [Thinking Rooms]
10. **Outside-catering charge: $43 reset fee.** The Workshop page states in its footer notes: “A $43 reset fee applies when outside catering is brought into The Workshop.” [Thinking Rooms]

In short: the page gives all the requested operational details except the booking-coordination fee/GST treatment, lift-door width, and returning-guest discount/qualification, which I would not estimate.
