用 GPT-6 Astra 复核报税，从补缴 11.7 万变成退税 19.1 万
作者让 Astra 花 90 分钟逐行核对税表与原始凭证，输出 15 页报告，会计师逐条确认后结论翻转，差额 30 万美元。
I just got the draft of my 2025 tax return - it says I owe $117,360 of tax. On top of what I already paid. Oof. But it didn't feel right to me. I asked ChatGPT Astra to do a secondary review, ticking and tying every number to source documents. Max effort. It ran for 90 minutes. Output - a 15 page report. It says I'm actually due a $191,173 REFUND. I reviewed Astra's work line by line with my accountant. He agreed, the LLM is correct. I was about to send Uncle Sam $117,360. Instead, I'm getting back $191,173. That's a swing of $308,533 (!!!!!!) The LLM couldn't have done my tax return from scratch - I still need my accountant. But for massively complex detail oriented work, and LLM is the best thought partner you can have. Connect a frontier LLM to your email and file storage, then ask it to review your past tax returns. You never know what it might find. My prompt is in the next tweet.
