In 2023, the choice for businesses was simple: either use a consumer chatbot or invest millions in building a custom RAG pipeline. By 2026, that binary decision is obsolete. AI agents now execute real work inside business software, compile data autonomously, and complete workflows without constant human input. This shifts the question from a single "build or buy" to a four-layer decision: for the model, the workflow, the data, and the business software, companies must now choose to build, buy, partner, or wait. Get any layer wrong and you risk technical debt, vendor lock-in, or a capability gap that competitors will close first.

Why the Old Question Broke

The original "build vs. buy" framework made sense in 2023 because off-the-shelf AI wasn't built for business. Consumer chatbots like early ChatGPT or Bard had no business context, so companies had to either risk using them informally or build expensive, custom RAG pipelines. That calculus has fundamentally changed. A recent McKinsey study found that 88% of organizations now regularly use AI in business. More importantly, the capability of models has surged: the latest benchmarks show that GPT-5 can tie or outperform 85% of domain experts on economically valuable work. When a model can match a human expert, the infrastructure for deploying it in business contexts—bidirectional software integrations, pre-packaged agent wor

Show Notes

The most expensive AI mistake of 2026 won't show up on any invoice. 💸

It'll show up two years from now when you can't get your data out, your competitors are eating your lunch, or your team is stuck maintaining software no one actually wanted to build.

Because in 2026, AI isn't one decision anymore.

It's four.

The model. The workflows. Your data. Your business software.

Each layer has its own build, buy, partner, or wait choice.

And most companies are making all four without realizing it.

Today on Everyday AI, we're breaking down the framework that puts those choices back in your hands.
