90 tokens a second on Windows · NVIDIA 12 GB · 16 CPUs · 16 GB RAM. No hosted API sells it, so this network is the place to run it.
13 builds of Qwen 3 4B, 28 signed runs on real machines: different packagers, precisions and engines, each a different file with its own numbers.

Speed against price, every machine
Up and left is faster and cheaper · the line joins machines no other beats on both · price on a log scale
Same build, different machines
IQ3_XXS by unsloth on 4 machines: the fastest decodes 286× as fast as the slowest. One dot per machine, tokens per second.
What it fits on
The smallest build needs about 2.0 GB; 13 of 13 kinds of machine on the network can hold it. Bars: each kind's memory (its card's, else RAM) · ticks: every build, at the size it held plus a fifth for the prompt.
How far back it remembers, machine by machine
Filled: the needle came back at that prompt size · outlined: asked and lost · blank: not asked · trained for 40K. 2 walks ended because the model forgot, 1 because the machine could not hold the prompt.

The 14 longest of 24 walks; every one is on its build's page.
Carbon per million tokens
Lowest build on each machine · 1 of 1 read off a power sensor, the rest modelled from the parts · fewer grams is better
Carbon is location-based: signed energy × the yearly average of the grid where the machine signed its place (world grid average (place not signed); Ember Global Electricity Review 2025 (2024 generation), location-based). Facility overhead is not included. A machine on its own solar is not credited until it can prove it.
Measured by
The people whose machines signed these numbers
proved by at least one build: Tool calling · Tool loop finished · Faithful to tool results · Chained tool calls · Structured output · Sustained output · Extended thinking · Vision · Counts in images · Spatial reasoning · Writes code · Reasons about code · Synthesises sources · Follows instructions
Each its own file with its own page: the machines that ran it and their signatures.
