Choose an AI approach for each use case, not for the business as a whole. Buy a mature product for a common need when its terms and integrations fit; build or adapt when a distinctive requirement and the capacity to operate the system justify the work; consider privately hosted or open-weight models when deployment control matters enough to take on the extra responsibilities. Test each option against the same task and compare the cost of successful outcomes—not just model fees.
Should we build our own AI or buy a solution?
Start by defining the business problem, then check whether AI is a suitable way to solve it. A conventional workflow, rules-based system, or non-AI product may be safer or more economical. The UK Government’s guidance recommends considering whether the need is unique, whether a commercial product is mature enough, how the solution will integrate, and whether the team can build and operate an in-house system. Its criteria are useful beyond public procurement, but businesses in other jurisdictions should apply their own procurement and legal requirements. Read the UK Government’s assessment guidance.
| Option | Consider it when | What the organization must evaluate or own |
|---|---|---|
| Buy a finished AI application | A common task is covered by a mature product and its terms, controls, and integrations suit the use. | Vendor terms, the data users may enter, integration into the full service, output review, accountability, and any customization. |
| Use a commercial model API or managed service | You need model capabilities inside your own product or workflow and want the provider to manage some infrastructure. | Data handling, controls for prompts and outputs, service or model changes, evaluation, monitoring, provider dependence, and total cost at forecast usage. |
| Adapt a pre-trained or open-weight model | Domain fit, modification, or deployment control justifies adaptation, and the team can test and operate the result. | Model and dataset licenses, task-specific performance, hosting and inference, security updates, specialist skills, and responsibilities across providers and integrators. |
| Build a new model or substantial custom system | Existing products and models do not meet genuinely distinctive requirements, and the case supports sustained investment. | Data rights and quality, research and engineering capacity, training and compute, evaluation, governance, and production maintenance. First check whether retrieval or adapting an existing model would suffice. |
| Do not use AI for this task | A non-AI approach meets the need more safely or economically, or testing shows the AI option falls short. | Compare with a non-AI baseline, including the consequences and cost of errors, review, and operating complexity. |
Buying a product does not remove the need to integrate it into the end-to-end service. Likewise, using a model API does not mean the provider makes every decision about how the resulting workflow is designed, checked, or used.
How can we compare the options fairly?
Run a small proof of concept before committing to a build, contract, or production deployment. Compare each candidate on the same representative cases and against a non-AI baseline where practical.

- Define the task and success criteria. Write down the task in plain terms, what counts as a successful result, acceptable error rates, and the conditions that require a person to review or override an output.
- Choose representative test cases. Include ordinary examples as well as difficult and sensitive cases. Use data you are permitted to use, and make the test reflect the conditions of the intended workflow.
- Measure more than answer quality. Record quality, latency, failure modes, user acceptance, integration effort, and staff review time. Assess whether the system fails safely when it cannot complete the task.
- Estimate the cost of delivering the outcome. Include application or API fees, compute, storage, data preparation, engineering, integration, security, monitoring, retries, human review, incident response, and model upgrades at expected usage.
- Decide whether the evidence meets the bar. Compare with the baseline and the agreed success criteria. Do not assume a vendor example establishes a break-even point for your workload; there is no universal build-versus-buy volume threshold established here.
OpenAI offers a useful vendor-authored way to frame the economics: “The right measure is the cost of a successful outcome, including the time, retries, oversight, and errors required to get there.” That is a measurement principle, not independent proof that any particular option will be cheaper. OpenAI’s article, published July 31, 2026, also reports internal improvements to its own serving costs and token-generation efficiency; those company-reported results are not estimates of savings available to other businesses.
When does it make sense to use an open-source AI model?
Consider an open-weight model or another privately hosted model when the ability to control where and how it runs is important enough to justify added operational work. “Open-source” can refer to more than downloadable weights: check the exact model’s license and terms, and do not assume that access to weights alone makes the whole system open source.

Deployment choices have different data flows. A public application, a model API, managed hosting, private hosting, local execution, and training a model are not interchangeable. A private deployment can keep data within an environment the organization owns, but that does not make it secure automatically. An API may offer additional controls, yet data sent to the provider still needs to be assessed under the applicable terms and safeguards.
The UK Government’s AI Playbook cautions that models runnable locally may not match the scale of public services and are not recommended for most production services. It also describes the adopter’s responsibility for securing and updating privately hosted models, maintaining infrastructure, and providing specialist machine-learning operations. These are deployment trade-offs, not evidence that open or closed models are inherently more secure. See the UK Government AI Playbook.

What should we check before sending business data to an AI service?
Match the data controls to the actual use case and the rules that apply to your organization. Before use, establish what information may be entered and verify the relevant contractual and technical arrangements.
- Classify the data, including personal, confidential, regulated, or commercially sensitive information.
- Check retention and deletion terms, whether data may be used for training, provider access, logging, and available access controls.
- Confirm hosting region and residency requirements, and review contractual commitments rather than relying on general product descriptions.
- Assess the full system’s threat model, including the model release components, the application around it, and the way users and connected services can access it.
- Plan how prompts and outputs will be filtered, reviewed, and logged. Controls such as audit logs or privacy-enhancing technologies can reduce some risks but do not replace assessment of the data flow.
Provider terms and product controls change; verify current official terms for the exact service, model version, and deployment before relying on them. The AI Playbook says open-source and closed-source models are not inherently more or less secure: security depends on the model, release components, threat model, deployment, data, and maintenance practices. OpenAI’s deployment guidance discusses publishing usage rules, enforcing them, evaluating behavior, documenting weaknesses, and gathering stakeholder input. It is provider-authored guidance and notes that its principles evolve.
Can a business use different AI approaches for different tasks?
Yes. A business can use a commercial product for a routine workflow, a managed model for a custom feature, and a more controlled deployment for a critical use case—if each choice has a clear owner and suitable checks. The right balance can vary with sensitivity, risk, required control, capabilities, cost, and strategic importance.
A 2026 paper on government LLM strategy describes pluralistic approaches that use commercial models for commodity or non-sensitive needs while pursuing greater control for critical, high-risk, or strategically important applications. Its framework includes sovereignty, safety, cost, resource capability, cultural fit, and sustainability; it is public-sector research to adapt thoughtfully, not a prescription for private businesses. Read the paper.
Who is accountable when several providers are involved?
With adapted or hosted models, the service may depend on several actors: cloud or compute providers, data suppliers, model providers, model hubs or hosting platforms, adapters, application integrators, distribution platforms, and evaluation or MLOps providers. A failure can cross those boundaries, so the business using the system should identify who owns each decision and how issues are escalated. Partnership on AI maps these parts of the ecosystem and the shared risk-management challenge. See its ecosystem map.
Assign accountable owners for data, model selection, application code, deployment, testing, monitoring, and incident response. Keep evaluating after launch: usage, inputs, model behavior, and provider services can change, so the proof-of-concept result alone is not a production assurance.
