Configuration: Prime Intellect Verifiers v0.3.1, task-native tests, temperature 0, fresh environment per attempt. The September 23 Muse cell used its recommended temperature 1.0. These are historical binaries; the current 0.2.3 release has no published full-suite result. Host CPU/GPU and memory were not recorded in the public summaries, so these figures are not hardware throughput claims.

The interactive plots below use the original September 21 cells. They do not describe the current release. Agent wall time includes failed attempts; it is not a measure of overall campaign elapsed time.
