Resources · 15 pages

Resources, for people deciding.

Guides, explainers, comparisons and a glossary, written for the person who has to choose — and who will be asked to defend the choice to someone who has not read the vendor pitch.

Introduction transcript. Client: Could someone explain this without the sales pitch? Qubi: Ooh, yes. I’ve got just the page. Qubi: Practical guides, clear explainers, and questions worth asking. Client: So I can actually defend my decision? Qubi: That’s the idea. Read it, check it, make it yours. Qubi: Start with the question on your mind.

At a glance

Read it, then decide.

01 What is here
Practical guides, technical explainers, comparisons, frameworks and a glossary, grouped by what you are trying to decide.
02 Who it is for
The person who has to choose, and who will be asked to defend the choice to someone who has not read the vendor pitch.
03 How it stays current
Every resource is listed from the site’s registry, so a new explainer appears in the index without a hand-edit.
04 The next step
If a page describes your problem, the next step is a conversation about your numbers, not a deck.

Vendor comparison

Compare vendors on what they have shipped.

Start with the questions that separate a vendor who has shipped from one who has only demoed, then check the build and agency calls before you shortlist.

  1. 1Read how to write an AI RFP: the questions that separate shipped from demoed, and what to ask for instead of a fixed price.
  2. 2Decide whether an off-the-shelf product or a custom build fits: Build vs Buy AI.
  3. 3Weigh an AI agency against an in-house team on cost and time.
  4. 4Check the model choice against your constraints, not against benchmarks: How to Choose a Model.
Design

Build it on a design you can defend.

Learn the mechanism well enough to reason about why a system fails, then the orchestration and retrieval choices that follow from it.

  1. 1Learn enough of the mechanism to reason about failure: How LLMs Actually Work.
  2. 2Learn what a context window really costs: Tokens & Context Windows.
  3. 3See how routing, tool use and multi-step reasoning fit together: LLM Orchestration Explained.
  4. 4Decide when to retrieve and when to fine-tune: RAG vs Fine-Tuning.
  5. 5Understand why prompt injection is not solved, and how to design an agent that fails safely: Prompt Injection Explained.
Procurement

Put the case in writing before the review.

A procurement review asks what it costs, where the models run and what data leaves the building. These pages answer those in the order a review asks them.

  1. 1Check whether the data can support the system before you commission it: Is Your Data Ready for AI?
  2. 2Model the full cost, including the lines usually left out: Modelling the Cost of an AI System.
  3. 3Decide where the models run, on premise or in the cloud: On-Premise vs Cloud AI.
  4. 4Threat-model agentic systems for prompt injection, tool abuse and excessive agency: AI Agent Security for Enterprise.
Business case

Build a case that survives the costs usually omitted.

Start with the framework for a defensible case, then test the cost model and the build-or-buy and agency-or-in-house calls it depends on.

  1. 1Build the case with the framework that includes the costs usually omitted: The ROI of AI Automation.
  2. 2Build a cost model that survives production, including the lines usually left out: Modelling the Cost of an AI System.
  3. 3Test the build-or-buy call against the case: Build vs Buy AI.
  4. 4Compare an AI agency with an in-house team on real cost and time: AI Agency vs In-House Team.
