Abstract
Abstract:Above 962 °C, the ITS-90 is realized at the National Research Council (NRC) of Canada by a standard radiation thermometer with a known spectral responsivity and a silver freezing-point blackbody. Together with Planck's law, the temperature scale can be extrapolated to temperatures in excess of 2500 °C, albeit with uncertainties that increase with higher temperatures. This realization can then be disseminated to other radiation thermometers via a variable-temperature blackbody for use in, for example, calibration laboratories. In the future, it is expected that new high-temperature fixed points with transition temperatures exceeding 3000 °C will allow an interpolated high-temperature realization and lower uncertainties.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
