Kroma
The README says MIT. The repo tag — and the merged base weights — say otherwise
What it is
Lodestones — the community fine-tuner behind the Chroma line — retrains Krea 2 into Kroma, with the Krea 2 Turbo delta merged in as a rank-512 LoRA. v0.2 abandons the v0.1 LoRA-plus-diff packaging for a single full checkpoint: load it in any recent ComfyUI with native Krea 2 support (Qwen3-VL text encoder + VAE), sample at 8–12 steps, CFG 1.0–1.5.
Why it's interesting
It's the fastest-moving community checkpoint in the Krea 2 ecosystem, and it's this week's textbook licensing case: the README declares MIT for the fine-tune while explicitly granting no rights to the base weights — which are physically inside the merged checkpoint you download. The file you get is governed by the Krea 2 Community License, and the HF tag says exactly that.
Use cases
- ComfyUI image workflows on the Krea 2 stack with turbo-speed sampling
- Community fine-tune and LoRA experimentation on a current-gen base
- A case study in how licenses actually propagate through merged checkpoints
Who it's for
ComfyUI users, fine-tuners — and anyone who ships image models commercially
Setup
Moderate. Recent ComfyUI with native Krea 2 support, plus the Krea 2 text encoder (Qwen3-VL) and VAE; quantized w4a8 community builds exist for smaller GPUs
Limitations & cautions
No LICENSE file in the repo means the terms live in a tag and a base-model PDF two hops away; the checkpoint requires the Krea 2 encoder stack regardless; and as a one-maintainer community project, cadence and support are best-effort.
Editorial takeaway
A checkpoint is not a diff. Merge restricted weights into your MIT fine-tune and the restriction is what ships — this is why we read tags, not READMEs.
