A company is considering whether to build or buy an AI model for a niche legal-document analysis task. The company has a small data-science team that could build a custom model in six months. A commercial API exists but does not fully support the niche task. The company's legal department requires full control over the model's outputs. What should the architect recommend?

Buy the commercial API and adapt the workflow to its capabilities

Use a model router to combine the commercial API with a rule-based fallback

Build a custom model, accepting the longer timeline and higher cost

Extend an open-source model with fine-tuning

In a build vs. buy vs. extend analysis for an AI component, what does 'extend' typically mean?

Modifying or adding capabilities to an existing AI solution or model to meet specific business needs

Purchasing a third-party AI solution and using it as-is

Outsourcing the development of the AI component to a vendor

Developing a completely new AI model from scratch

A retail company needs a customer-service chatbot. They have a small IT team with no AI expertise, a tight deadline of two months, and a limited budget. The chatbot must integrate with their existing CRM. Which approach is most appropriate?

Extend an existing internal IT application with a simple rule-based script

Outsource the entire chatbot development to a third-party vendor

Build a custom chatbot from scratch using open-source AI models

Buy a prebuilt chatbot solution and customize its integration with the CRM

A company uses multiple AI models for different tasks: a small fast model for simple queries, a large accurate model for complex reasoning, and a specialized model for code generation. They want to minimize cost while maintaining quality. What should the architect implement?

A load balancer that distributes requests evenly across all models

A model router that sends each request to the most appropriate model based on the task type and complexity

A caching layer that stores responses for repeated queries

A single large model for all requests to ensure consistent quality

When deciding whether to build, buy, or extend an AI component, which of the following is a key consideration?

The availability of in-house expertise to develop and maintain the component

The number of end-users who will use the solution

The choice of cloud provider for hosting the solution

The color scheme of the user interface
