The prompt and the run
Berman gives Codex a goal of cloning Excel with full feature parity. He says the run continued for more than 12 days before he stopped it.
I gave Codex a short goal: `/goal Clone excel, full feature parity`. It ran for more than 12 days before I manually stopped it. I was impressed by the result.
Codex opened Excel on my computer, looked at features in the real desktop app and built its own version, I say. The resulting spreadsheet looks like Excel to me.
The resulting spreadsheet
He shows the interface and demonstrates a simple formula and sorting. His broad claims about completeness go beyond the examples shown.
I demonstrate adjustable columns and cell selection, then enter `=1+2` and show the result, 3. I describe the formulas and formatting as working and call the result feature-complete. The brief demonstration shows only a few examples, so it does not establish that all formulas and formatting work or that the clone matches every Excel feature.
I select the sort button and choose ascending order, showing the values sorted. After stopping the run myself, I wonder how long it would have continued otherwise.
