The Atlas · 180 models · checked 12 Oct 2026
The AI model market, on one map.
Every model sits in a square: its column is what it costs per 1M input tokens, its row is how much context it holds. Models that share a square are direct substitutes on those two numbers, so the map answers “what else is like this, for less?” at a glance.

Columns
A free · B under $0.10 · C $0.10–0.30 · D $0.30–1 · E $1–3 · F $3–10 · G $10–30 · H $30 and up. Bands are logarithmic: each step is about 3×.
Rows
1 under 32K · 2 32–128K · 3 128–256K · 4 256K–1M · 5 about 1M · 6 over 1M tokens.

Questions about the Atlas
What does a grid reference like D5 mean?
D is the price column ($0.30–1 per 1M input tokens) and 5 is the context row (1M). D5 is the busiest square, with 15 models, including DeepSeek V4.1 Flash, Gemini 2.5 Flash and Gemini 3.5 Flash Lite. Models in one square are like-for-like on price and context only.
Which price does the map use when a model has several hosts?
The cheapest available standard-tier input price in our catalogue. Batch, free and thinking tiers are rows on each model page but do not move the dot. A model with no standard-tier price, or no context window, is not on the map.
How current is the map?
The plate is rebuilt whenever the catalogue changes. The newest price on it was checked 12 Oct 2026; each model page carries its own date.
How many models are not on the map?
180 models have both a price and a context window and appear here. The rest are listed in the model directory but cannot be placed until we hold both numbers.
