OpenAI's self-improving AI tax agent slashes filing time 30%
OpenAI partnered with Thrive Holdings and Crete to build a Codex‑powered tax agent that autonomously learns from production data. In its pilot, the system processed 7,000 returns, reducing accountant effort by about a third, achieving up to 97% accuracy, and improving correct field completion from 25% to 86% within six weeks.
