Kroma vs Krea 2: ComfyUI setup and image tests

This tutorial tests Kroma against Krea 2 in ComfyUI through portraits, an advertising poster and LoRA examples. The presenter introduces Kroma as a fine-tuned model by Loadstone and uses the v0.3.1 Turbo variant. The BF16 download is described as 26 GB; the speaker also points to GGUF and FP8 variants for systems with less VRAM, without specifying a minimum hardware requirement.

The initial workflow generates 2048×2048 images with 10 steps, the Euler sampler, the simple scheduler and a shift value of 1.15. For comparison, the presenter runs the same prompt and settings with the official Krea 2 Turbo FP8 model. In the first portrait, the speaker prefers Kroma's contrast and detail but considers Krea 2 more realistic. These are judgments about the examples shown, rather than a general performance ranking.

Further tests apply a LoRA at 0.85 strength and try another sampler before returning to Euler. A poster prompt checks text and layout; the presenter reports that the generated wording is correct. The final compatibility test uses a LoRA trained on Krea 2 with shift disabled. The speaker says it works partly on Kroma but does not reproduce the intended subject perfectly.
