21.7x

fewer Claude tokens in one matched development task.

In this experiment, Claude token usage fell 95.38% and the Claude account cost fell 78.84%. Both outputs were checked against the same task reference.

The benchmark task: a particle simulation

The video illustrates the task. The figures below compare the recorded Claude Stock run with the run using happyllama.

These figures describe one matched development task, not a guarantee of savings on other work. Local model computation is reported separately; hardware, electricity and operator time are not included in the Claude account cost.

Same task, same model, same reasoning effort, and the same machine. The scene is a 4096 particle vortex integrated at a fixed timestep; every number is read out of the running page and checked against a reference written before either side saw the task. Costs are what the account was billed.
