¿Los agentes sustituyen al RAG? Los datos dicen que no: la exploración agresiva dispara el coste sin mejorar la precisión, y usar un LLM para recuperación puede ser 1.431 veces más caro que un modelo de embeddings especializado. El agente no sustituye al RAG, lo absorbe como una capacidad interna.

Why it matters
In data, the problem is almost never the tool. It is that two areas mean different things by customer and neither wants to give ground. You can install the most modern platform on the market and still have three sales figures in the same meeting.
My criterion is that data only helps if it arrives in time for the decision it is meant to support. A perfect report that lands on the eighth for a decision taken on the third is a useless report, however correct it is. Timeliness beats precision more often than people admit.
What usually goes wrong
The frequent mistake is starting with the tool instead of the question. The platform gets bought, everything gets connected, and only then does somebody sit down to think about what they wanted to know. It almost always turns out the important question needed data nobody was capturing.
What to watch
- Who answers for the quality of the indicator when somebody challenges it in a committee.
- Which concrete decision changes because of this and who makes it: without that, it is one more dashboard.
- Whether definitions are agreed across areas or each one brings its own to the meeting.
How I read this entry
If this reached an organisation, I would start by agreeing ten definitions rather than a hundred: what an active customer is, what a sale is, when it counts. Written, signed and published. It is a week of uncomfortable argument that saves two years of meetings where nobody agrees.
The original story is published in another language; the excerpt is quoted as the publisher delivers it and the commentary is written in English.
