Summary
This is a technical report introducing Krea 2 (K2), an open-weights text-to-image foundation model for creative exploration. The report discusses the rapid progress in image generation driven by scalable transformer architectures, improved captioning and text encoders, better latent representations, and pipelined post-training techniques. It details the development of two model variants: K2 Raw and K2 Turbo, both released as open weights. The paper covers the technical architecture, training methodology, and capabilities of these models in the context of the broader field's evolution toward more reliable and high-quality image synthesis.

· 3 pulledDiffusion and flow-matching models can generate high-resolution images, produce sharp photorealism and stable structure, render dense text, encode broad world knowledge, and follow user prompts in precise detail.
These improvements have been driven by several interacting factors including scalable transformers architectures, improved captioning and text encoders, better latent representations, and pipelined post-training techniques.
Release includes K2 Raw and K2 Turbo open weights.
