OpenAI Says GPT-6 Astra Finished a 50-Tab Tax Workbook Twice as Fast
OpenAI's write-up says GPT-6 Astra completed a 50-tab tax workbook twice as fast as GPT-5.6 Sol, and credits the newer model's stronger understanding of user intent with giving Basis more confidence in real-world use.
It is the vendor's own comparison, run against a previous model on a single workbook, and what it measures is time rather than accuracy.

Speed is the easy number to publish. A tax workbook is full of cells where fast and wrong are indistinguishable until somebody opens the file and checks.

The intent claim may be the one that actually decides adoption. An agent that misreads what was asked burns a reviewer's hours, and that is exactly where a doubling in speed can quietly disappear.
