A Simple Model Routing Pattern for AI Product Teams

Many AI apps start with one model call. That works early, but product behavior quickly becomes more complex.
Some requests need speed. Some need deeper reasoning. Some need stable formatting. A practical AI stack should separate product intent from model selection.
const route = selectModelRoute({
task: "support_summary",
priority: "low_latency",
format: "structured_json"
})

const result = await vectorEngine.run({
route,
input: userMessage
})
With VectorNode / VectorEngine, the idea is to treat model access as a routing workspace, not scattered provider logic inside every feature.

The key benefit is clarity: product teams can test, adjust, and organize model behavior without rewriting the whole application path each time.
