How to Choose an AI Model for Your Business Use Case
A practical framework for choosing an AI model — matching capability, cost, latency, context and data requirements to the specific use case rather than defaulting to the best-known name.
A procurement-ready framework for evaluating enterprise AI vendors — covering capability, data handling, security, integration, cost, support and viability — beyond the sales demo.
Evaluating an enterprise AI vendor means assessing them across capability on your actual use cases, data handling and privacy terms, security posture, integration with your systems, total cost at scale, support, and the vendor's own viability — not judging them on a sales demo. Demos are curated to impress and rarely reflect your real data, your integration complexity, or what the product will cost once usage scales. A procurement-ready framework tests each of these dimensions directly, giving the organisation evidence rather than impressions. For Australian enterprises, this discipline is what separates an AI purchase that delivers from one that disappoints after the contract is signed.
AI vendor evaluation is a multi-dimensional assessment, yet it is often reduced to "did the demo look good?" The demo answers one narrow question — apparent capability under favourable conditions — and leaves the rest unexamined. Sound procurement broadens the lens to the factors that actually determine value in production.
Those factors include how the vendor treats your data, whether the product integrates with your environment, how cost behaves at your scale, what happens when something breaks, and whether the vendor will still be a sound partner in two years. Each is as decisive as raw capability.
Poor vendor selection is expensive and hard to reverse. A vendor chosen on a demo may turn out to have unacceptable data terms, weak security, painful integration or runaway cost at scale — discovered only after commitment, when switching is costly.
IBM's research found that a majority of CEOs are delaying major AI investment until governance and clarity improve; rigorous vendor evaluation is part of that clarity. For Australian organisations, it is also where compliance is protected — a vendor's data-handling and hosting terms determine whether using them is consistent with the Privacy Act and any residency obligations. Procurement discipline converts an AI purchase from a leap of faith into a managed decision.
A procurement-ready framework assesses vendors across these dimensions:
| Dimension | What to test |
|---|---|
| Capability | Performance on your real use cases and data, not just the demo |
| Data handling | Retention, training-use, residency, deletion and ownership terms |
| Security | Certifications, access controls, encryption, breach history |
| Integration | Fit with your existing systems and APIs |
| Cost | Total cost at your expected scale, including overages |
| Support | Responsiveness, SLAs, onboarding and ongoing help |
| Viability | Vendor's financial stability, roadmap and track record |
| Portability | How hard it would be to leave |
The two most commonly underweighted dimensions are data handling and cost at scale. A capable product with unacceptable data terms is unusable for sensitive workloads, and an attractively priced demo can become expensive once real volume flows through it.
Test on your own data and integration where possible, through a proof of concept rather than a demo. A short, structured pilot reveals integration friction, real-world quality and cost behaviour that a demonstration conceals.
Edison AI's strategy and implementation team helps organisations run AI vendor evaluations to procurement standard — defining requirements, structuring proofs of concept, and assessing data, security and cost terms — so the decision rests on evidence. This is particularly valuable for organisations without in-house AI expertise, who are otherwise reliant on vendor claims.
Include portability in the assessment. A vendor you cannot leave has leverage over you; understanding the exit cost before signing is part of sound procurement.
Evaluate AI vendors across the full set of dimensions — capability on your data, data handling, security, integration, cost at scale, support, viability and portability — rather than on a demo. Run a structured proof of concept on your own data and systems. Scrutinise data-handling and hosting terms against your privacy and residency obligations. Understand the exit cost before committing. Apply the same procurement rigour to AI that you would to any significant enterprise system, so the decision is grounded in evidence and protects both value and compliance.
An AI readiness audit maps the highest-return use cases before you commit to a model or platform.
Assess them across capability on your use cases, data handling and privacy terms, security posture, integration with your systems, total cost, support and the vendor's viability. A demo shows capability; procurement requires evidence across all these dimensions.
Ask how your data is used and retained, where it is hosted, what security certifications they hold, how the product integrates with your stack, how pricing scales with usage, what support they provide, and how they handle model updates and accuracy.
Demos are curated to impress and rarely reflect your real data, integration complexity, data-handling terms or cost at scale. Sound procurement tests these factors directly rather than relying on a controlled demonstration.
