This workflow has GPT-6.1 Terra and GPT-6.1 Sol fill out the same long, general-purpose form in Fast mode, with screen recordings shown side by side. The author reports that Terra took 53.5 seconds and Sol took 3 minutes 21.7 seconds, but this was a single personal run and does not represent all computer-use tasks.
Suitable task: Observe how two models handle browser form-filling, and compare their completion times, using the same form and mode.
Unsuitable task: Use a single run to infer the models' general speed or quality on other websites, forms, control methods, or tasks; enter real sensitive information or submit a form without authorization.
Applicable model versions: GPT-6.1 Terra and GPT-6.1 Sol.
Applicable client, agent, or API: The post does not specify a particular client, agent, or API; the task requires the model to operate the computer and record the process.
Recommended reasoning level and parameters: The author used Fast mode; reasoning level, other parameters, and tool configuration were not specified.
The following is an English editorial paraphrase of the author's task description, not a verbatim translation. Before using it, limit the form to a public or demo form that is safe to test, and avoid entering real personal information:
Find a long, general-purpose form online. First, fill it out with GPT-6.1 Terra in Fast mode and record the process. Then fill out the exact same form with GPT-6.1 Sol in Fast mode and record that process too. Finally, show the two recordings side by side for comparison.Choose one long, general-purpose form and confirm it is suitable for a demo and does not require submitting real personal information.
Fill it out with GPT-6.1 Terra in Fast mode and record the process.
Restore the form to the same starting state, then fill it out with GPT-6.1 Sol in Fast mode and record the process.
Show the two recordings side by side, record the completion times, and state the computer-control method actually used in each run.
Keep the form, starting state, and mode consistent when comparing results. If the control method or other conditions differ, note that separately.

D --> EThe author says he compared GPT-6.1 Terra's computer-use process with Sol's and provided the form-filling task above as the prompt.
The author reports that, in the original runs on the same form, Terra took 53.5 seconds and Sol took 3 minutes 21.7 seconds, a difference of 2 minutes 28.2 seconds.
The author explains that the timed runs used accessibility controls; the recorded video in the post used mouse control so the cursor would be visible. The control method shown in the video therefore differs from that used in the timed runs described by the author.
Both models ran in Fast mode. The post does not specify the number of repetitions, form name, form difficulty, entries, details of the starting state, or other run parameters.
The author reported the times. This article did not independently replay or verify the operations in the video, or repeat the comparison.
There is data for only one set of runs, so it cannot establish the models' average speed on general computer-use tasks or other forms.
The timed runs used accessibility controls, while the public video used mouse control. Do not treat the cursor movements in the video as a record of the control method used in the timed runs.
The post does not provide enough detail to fully reproduce the form or process, and it does not report form-filling accuracy. A comparison of completion times is not a comparison of quality.
