Building self-improving tax agents with Codex

OpenAI
OpenAI collaborated with tax professionals to create an AI agent that uses production feedback and Codex to continuously self-improve and automate tax returns.

Summary

OpenAI partnered with Thrive Holdings and accounting firm Crete to develop "Tax AI," an agent designed to automate complex tax return preparation. By integrating expert practitioner feedback, detailed production traces, and a Codex-driven iteration loop, the system transforms real-world errors into structured data. This data serves as benchmarks for continuous evaluation and automated code improvements, allowing the system to increase its accuracy and efficiency over time without manual intervention for every edge case.
