Guides (8)

How this actually works, written down.

Each piece answers one question a buyer actually asks, with the numbers sourced and the limits stated. No trend pieces and no predictions.

Every guide below is written the way this drawing works: what survives is what can show where it came from.

Field guideHow to stop AI hallucinationsFour mechanisms that cut invented answers, the number to demand for each, and the eight questions that expose a vendor who has never measured one.Read the field guide
A glass beam-splitter cube in a matte black mount on a dark optical breadboard. One violet beam enters from the left, brightens on the diagonal inside the cube, and one beam leaves to the right.

Ordered by what you are trying to work out rather than by date. Each one states its own limits.

  1. A vintage film projector on a table in a dark room, rim-lit violet, projecting a bright beam through drifting dust onto a screen that shows nothing but an empty violet rectangle.01Why AI makes up answers, and what stops itHow next-token prediction produces confident invented facts, why the scoreboard keeps rewarding it, and what that means for what you buy.
  2. Five identical machines in a row on a dark workshop floor, four under fitted dust covers. The second is uncovered and running, its violet spindle light pooling on the concrete around it.02Why AI projects fail between the demo and the deadlineFive failure patterns, the symptom each one shows first, and an eight-question checklist to hold your own pilot against at week nine.
  3. Two objects under one violet pendant lamp on a dark bench: an open card-index drawer full of tabbed file cards beside a sealed matte black cube of the same size.03RAG vs fine-tuning: what each one costs to ownRAG is short for retrieval-augmented generation. One decision rule, two vendor deprecation clocks you have not planned for, and the two-year cost of owning each approach.

Then the rest of the cluster

  1. 4 August 2026Build vs buy AI agents, and the fourth option nobody sells youFour routes to an AI agent, what each one costs you in speed, control and lock-in, and the five-step rule that picks between them.
  2. 4 August 2026What AI agent development costs, to build and to runThe eight things that move a build quote, the seven lines on a monthly run bill, and a worked example priced from live provider pages.
  3. 4 August 2026How to evaluate a RAG system before you trust itRAG is short for retrieval-augmented generation. Six test families, and the threshold to gate each one at. No industry-standard passing score exists, so here is how to set your own.
  4. 4 August 2026Twelve questions to ask before you hire an AI development companyTwelve questions a team that has shipped and operated AI can answer with a number, a mechanism or a name, and the weak answers to listen for.
