33. Model Selection Strategy

Select a model based on task type, risk, speed, privacy, and available context.

The lesson

Simple formatting, summarisation, and brainstorming often work on cheaper models. Architecture, debugging, legal-like risk, and complex code need stronger models.

Local models are attractive for private work. Cloud frontier models are attractive for difficult reasoning.

The expert habit is to match model strength to business risk instead of always choosing the newest model.

A risk analyst at a bank uses TPEE to match model strength to business risk, drafting summaries on a cheaper model and reserving a stronger one for regulatory interpretation.

An engineer at a solar installer uses TPEE to choose a local model for private design data and a cloud model only for general code help, recording the reason for each choice.

A hospital data manager keeps patient-related drafting on a locally run model and uses a cloud model only for anonymised wording checks.

A software developer at a small studio uses TPEE to pick a reasoning-strong model for debugging and a fast cheap model for formatting changes.

A paralegal uses TPEE to route contract questions to a stronger model because the consequence of a wrong answer is high, and routine tidy-ups to a cheaper one.

A marketing coordinator drafts campaign ideas on a cheap fast model in TPEE and moves only the chosen concept to a stronger model for refinement.

A maintenance planner at a factory uses TPEE to summarise routine work orders on a low-cost model, saving the stronger model for fault analysis.

A government records officer keeps confidential drafting on a local model and uses a cloud model only for public-facing summaries.

A veterinary practice manager uses TPEE to draft routine client reminders on a cheap model and to review complex case notes on a stronger one.

A logistics analyst selects a reasoning model in TPEE for multi-step route comparisons and a cheaper model for daily status summaries.

Check yourself

Question 1: Which tasks often work on cheaper models?
  1. Deep architecture under uncertainty
  2. Critical security review
  3. Complex debugging
  4. Formatting, summaries, brainstorming, simple transformations — correct

Answer: Formatting, summaries, brainstorming, simple transformations

Simple tasks do not always need frontier models.

Question 2: When are local models attractive?
  1. When best reasoning is guaranteed
  2. When internet-only is required
  3. Private work and user-controlled experiments — correct
  4. When no hardware exists

Answer: Private work and user-controlled experiments

Local models help privacy and control.

Question 3: What is the expert model-selection habit?
  1. Ignore context needs
  2. Match model strength to task risk — correct
  3. Always choose newest
  4. Always choose cheapest

Answer: Match model strength to task risk

Risk, quality, cost, privacy, and speed should guide selection.
