Grok 4.5 is being pitched as strong for real-world work after a Ramp benchmark on 150,000 actual business invoices.

Ramp scored models on whether they predicted every correction a human would make.
Grok reportedly had the highest perfect-extraction rate, ahead of similarly priced Gemini Flash 3.6, GPT 5.6 Terra, and Sonnet 5.
The task requires long-context reasoning over 100K+ tokens of invoice history, business memory, and human corrections.
Ramp’s stated goal is zero-click accounts payable, where invoices are processed correctly without human intervention.
