Three years ago, replicating someone else's AI product meant hiring a team, designing an architecture, training a model or integrating someone else's through an API, and building an interface—months of work. Now any team with access to Claude, GPT, or Gemini and sound engineering discipline has the same set of building blocks: frontier-level models, the MCP protocol for connecting tools, and ready-made RAG patterns for working with company data. The technology is widely available.
The barrier has shifted to engineering: who can assemble these building blocks into a stable product faster and deliver it to users without bugs or downtime.
