AI agent cuts tax workbook time in half

Basis, a company that prepares tax filings, tested OpenAI's new GPT-6 Astra model on a real task: completing a 50-tab tax workbook. The model finished twice as fast as the previous GPT-5.6 Sol.

Speed wasn't the only gain — the Basis team reports that the new model reads user intent far more accurately and stays on task without drifting. In tax and accounting work, where a single mistake means a penalty or a redo, that kind of reliability matters more than shaved minutes.

Check how many hours your accounting team spends each month manually matching bank statements, invoices, and tax filings — that repetitive, high-volume work is exactly what gets automated first. 1Cifer's accounting layer already processes bank statements and cross-checks documents automatically, leaving people to review decisions rather than retype numbers.
