Training Krea 2: What matters in generative model training — Sangwu Lee, Krea.ai
Krea open-sourced Krea 2 medium, arguing big labs sacrifice image diversity for consistency via mode collapse
“the easiest and most reliable way to render a person is render the most boring average person that exists”
Krea.ai open-sourced the medium variant of Krea 2, their image foundation model, with stylistic diversity as a core design priority. The researcher argues that production-grade image models from big labs have mode-collapsed their outputs — trading creative range for reliability — producing visually safe but homogeneous results. Krea positions itself as a counterpoint, emphasizing diversity as a key training objective.
