› OpenAI describes GPT-6.1 Terra as a model with "precise computer use" - controlling a computer from screenshots - and lists form filling as one possible use.
› I tested that claim with a two-page leasing application: the model saw only a screenshot and a customer email containing traps, while the browser carried out each action, whether clicking or typing.
› Terra completed the form without errors in all four attempts, using 19 steps each time, for about $0.047 per attempt and in under a minute.
› The test form and email were in Polish, so the results are from a Polish-language test.At a glance (test run on 26 October 2026)Task: 15 fields across two form pages, 2 dropdown menus, a choice among three options and 2 consent boxes.
