Reka Edge Behavioral Fingerprint
How rekaai's Reka Edge answers one-word probe questions at temperature 1.0 — random numbers, colors, animals, coin flips — measured over 370 valid samples in the open dataset of "One Token Is Enough" (arXiv:2607.10252).

Answer distributions by probe cell
Empirical distributions of normalized one-word answers, per task and language. H is the Shannon entropy in bits; the uniform baseline is log2 of the answer-domain size.

Distributions: Tomáš Bruckner, "One Token Is Enough" (arXiv:2607.10252), official dataset Zenodo DOI 10.5281/zenodo.21278557, licensed CC-BY-4.0. Collected via OpenRouter at temperature 1.0 under the paper's fixed minimal one-word system prompt; answer keys are re-normalized with the checker's pipeline (color aliases, number words, coin h/t) so live probes are directly comparable.
