What to know
- Define success on the buyer’s workflow before accepting a general accuracy claim.
- Test representative inputs, important failure cases, and the effort required to review outputs.
- Document dependencies, data handling, change controls, and an exit path.
Translate the promise into a job
An AI startup may promise faster work, better decisions, or reliable automation. Each phrase needs a concrete meaning before it can support a purchase. Specify the input, required output, permitted actions, and person accountable for the result. A tool that drafts a response and a tool that sends it to a customer perform different jobs, even if their demonstrations look similar.
Imagine a hypothetical product that summarizes supplier contracts. The purchasing question is whether it reliably extracts the terms your team needs from the document types you actually receive. It is not whether a polished example sounds professional. Write down which omissions would invalidate an output and which cases must go to a qualified reviewer before the vendor selects the demonstration material.
Make the evidence travel with the claim
Ask what an accuracy figure measures. The vendor should be able to explain the test set, scoring method, sample selection, and relevant limitations. Anthropic’s evaluation guidance emphasizes specific and measurable success criteria. That principle also applies to purchasing: a number becomes useful only when the buyer understands the task and conditions that produced it.
For the contract example, measure individual required fields and consequential omissions separately. A system could extract party names well while missing renewal conditions that matter more to the business. Keep some evaluation documents outside the vendor’s tuning process. Agree how disagreements will be resolved and who has the expertise to determine whether the answer is acceptable for its intended use.

Test the inconvenient cases
Representative work includes messy files, unfamiliar layouts, missing information, and requests that cannot be answered from the supplied material. OpenAI’s evaluation guidance recommends task-specific testing and attention to edge cases. A buyer can apply this without accepting any vendor’s broad model ranking. The test should reflect the proposed product, its integrations, and the actual information available to it.
Use an authorized evaluation set that includes the exceptions your team already spends time handling. Ask the system to identify uncertainty rather than rewarding a plausible completion in every case. In the hypothetical contract workflow, an explicit missing-term flag may be more useful than a confident inferred date. Evaluate whether users can recognize and act on the distinction.
Follow the information beyond the interface
Request a data-flow explanation showing what leaves your environment, which providers receive it, what is retained, and who can access the resulting records. Distinguish product logs, uploaded files, generated outputs, and information sent to external tools. A statement about model training does not answer every retention or access question. Record the exact product and contractual scope of each commitment.
The architecture may contain an underlying model service, a search index, monitoring software, and human support access. Changing one supplier can change the arrangement. Ask how you will be notified of material changes and how previously stored data is handled. A small vendor can give a clear answer; a large vendor can give an unclear one. The size of the pitch deck is irrelevant.

Price the work left behind
Measure the total effort required to produce an accepted result. Include setup, integration, review, correction, escalation, and maintenance. In a hypothetical trial, a draft produced in one minute may still take a specialist several minutes to verify. The useful comparison is the complete workflow against a baseline, including the consequences of errors that escape review.
Ask who maintains prompts, reference material, and access permissions after the pilot. Ask what happens when the model or product changes and performance shifts. A model card can provide valuable information about intended use and limitations, as Hugging Face’s documentation explains, but it does not replace evidence about the startup’s assembled application or the contract that governs support.

Buy a controlled capability
A useful purchasing document ends with acceptance criteria, boundaries on permitted use, an accountable owner, and an exit procedure. Define how data and configuration can be exported, what must be deleted, and how work continues if the vendor is unavailable. Treat unresolved dependencies as items to investigate before expanding the product’s authority or making a larger commitment.
The objective is not to eliminate every uncertainty before trying useful software. It is to make uncertainty visible and proportionate to the decision. A startup earns a stronger case when it can show where its product succeeds, where it needs oversight, and how it responds when the evidence changes. Those answers are more durable than a demonstration built around the easiest possible task.
