When to Use This Guide

First AI Platform Purchase

Your finance team is adopting AI for the first time and you need to choose one platform to start with. Use the org-type recommendations to narrow from 7 options to 2.

Annual Vendor Review

You already use one LLM but want to know if a better fit has emerged. The comparison table highlights where each model improved in the past 12 months.

Large teams often use different models for different tasks. The use-case framework shows which model wins for compliance vs. modeling vs. research, so you can assign each to its strength.

Regulated Industry Evaluation

Banking, insurance, and healthcare CFOs face extra scrutiny. The guide flags data residency, GDPR, and compliance alignment for each model so you can shortlist safely.
