Terra is OpenAI's new mid-priced model, built to use software through the screen as a person does. OpenAI's models could already do this; what has changed is the price. On a test of professional software tasks, Terra scores the same as GPT-6 Astra, OpenAI's top model, at an estimated $0.29 a task instead of $4.82. For reading an invoice and entering its details into accounting software, that comes to about 20 cents.
Much routine office work happens in older software with no API, where a person copies figures from a PDF into the screen. A clerk who spends four minutes on an invoice at $30 an hour costs $2 per invoice, ten times what Terra costs.
For example, a distributor's accounts payable team enters 3,000 supplier invoices a month. Terra reads each PDF, fills in the supplier, amounts, tax and cost code, and saves the entry as an unposted draft. A clerk compares each draft with its PDF and posts it, in about a minute instead of four. The team gets 150 hours a month back for an AI bill of about $600.
The drafts are there because Terra does not get the same entry right every time, and a wrong invoice that is posted becomes a wrong payment. With drafts, the AI does the typing and a person still makes the decision that moves money. Within a year, the cheapest way to connect an old system to anything else will often be an AI that types into it.
