GPT-6.1 Terra: What OpenAI's New Model Means For Your Admin Hours
27 October 2026
OpenAI released GPT-6.1 Terra this week, a model built around two specific skills: visual reasoning, which means reading images, screenshots and scanned documents properly, and computer use, which means operating software and web pages the way a person would, clicking and typing through the steps itself. It is already available in ChatGPT and has been added to GitHub Copilot, so there is no waiting list and nothing new to buy.
What it means for your hours
For a construction or trades business, most admin time goes on moving the same information between places. A supplier's PDF price list into a spreadsheet. A photo of a delivery note into the accounts system. A scanned RAMS sheet into a shared folder before a job starts. Terra's visual reasoning means it can read that document properly rather than guessing at blurry text, and its computer use means it can then act on what it reads, filling in the destination itself instead of handing you a wall of text to copy out by hand.
Here is a worked example. Say someone in the office spends 20 minutes a day typing supplier invoices from photographed delivery notes into the accounts package. Across a 46 week working year that is roughly 76 hours of pure data entry. At even a modest £15 an hour, that is over £1,100 a year spent on one task, on one person's desk, for one job.
The catch worth knowing about
Computer use is still new. It works inside the tools OpenAI has tested it against, mainly browsers and a limited set of business apps, and it needs clear instructions and some supervision while you learn what it gets right and wrong. Treat the first fortnight as a trial, not a handover. Check its output against the real invoice or delivery note before anything goes anywhere near your accountant.
What to do this month
- If you already pay for ChatGPT Plus or Team, feed it a messy supplier PDF or a site photo and ask it to pull out the numbers you actually need.
- If your team uses GitHub Copilot for any internal tools, check whether Terra is now running as the default model, it may already be working in the background.
- Pick one small, repeatable job, such as logging a delivery note, and test it for a week before trusting the model with anything bigger.
