Why the Agent Harness Matters More Than the Model?
It’s hard to believe that our name is above OpenAI, Anthropic and Google.
Did we train a completely new model? No. Wellโฆwe did initially but then we changed our approach once we learned what actually matters.
Our verified SpreadsheetBench v2 result suggests otherwise.
Thing isโฆ we use frontier models too, but what makes the difference is the harness around them: spreadsheet-specific tools, visual feedback, Excelโs real calculation engine, context management and verification.

And thereโs a bigger reason this matters to Arito: Spreadsheets are basically executable business knowledge: forecasts, pricing logic, unit economics, assumptions and operating models.ย ๐๐ ๐ฐ๐ ๐๐๐ง ๐๐๐๐ฉ๐ฅ๐ฒ ๐ฎ๐ง๐๐๐ซ๐ฌ๐ญ๐๐ง๐ ๐ญ๐ก๐๐ฆ, ๐๐ซ๐ข๐ญ๐จ ๐๐๐ง ๐ฅ๐๐๐ซ๐ง ๐ก๐จ๐ฐ ๐ ๐๐ฎ๐ฌ๐ญ๐จ๐ฆ๐๐ซ’๐ฌ ๐๐ฎ๐ฌ๐ข๐ง๐๐ฌ๐ฌ ๐ฐ๐จ๐ซ๐ค๐ฌ ๐ฆ๐ฎ๐๐ก ๐๐๐ฌ๐ญ๐๐ซ.

The ranking is great validation. But the capability underneath it is what really matters.
