Overview

Eon-Blossom-31B is a 31 billion parameter language model developed by Cyclone Labs. It was constructed using a custom merge method, combining four distinct base models: LatitudeGames/Equinox-31B, ReadyArt/gemma-4-31B-it-scotoma-2, zerofata/G4-MeroMero-v2-31B, and Darkhn/Gemma-4-31B-Animus-V15.0. The merge configuration utilized the hcve method with specific parameters for tol, max_iter, and exhaustive settings, and outputs in bfloat16.
