Learn · guides grounded in the same sourced data as the directory

Learn the stack. Numbers included.

Every figure on this page is live, dated, and linked to the page it was read from — the same readings as the rest of the directory, not a number typed into a guide once and left to rot.

Path 01
What the stack is

Start here if "the AI stack" is a phrase you have nodded at without a picture behind it.

  1. 1 · The ten layers
  2. 2 · Browse by layer
Path 02
What it costs

The part most reading on this subject skips, and the part that decides the architecture.

  1. 1 · Price your workload
  2. 2 · GPU prices across providers
  3. 3 · Set a cached share
Path 03
Choosing the parts

Once you know the shape and the money, this is the decision itself.

  1. 1 · What GPU do I need
  2. 2 · Compare two products
  3. 3 · Build a stack
Path 04
Giving a model hands

For when the model works and now has to reach your systems.

  1. 1 · MCP servers
  2. 2 · Agent skills

Reading the numbers

The terms our tables use, defined once

$/GPU·hr

Per single GPU, per hour — an 8×H100 node at $18.40/hr is $2.30 here. Always normalized per GPU, so two sellers quoting different node sizes can be compared at all.

Blended $/1M

3 parts input to 1 part output — a typical chat mix. Heavy generation? Weight output yourself in the cost calculator. Input and output are never averaged into one rate anywhere else on this site.

Spread

Dearest ÷ cheapest for identical hardware or weights. Today: 3.8× on the widest GPU. It measures a market, never a product’s own range.

First reading

No trend until a second capture exists. Where you see it, we have met that seller once — it is honesty about how long we have been looking, not a missing number.
