Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Flux.1 fine-tuned via LoRA (rank 256) failed on all 300 test prompts, generating images of the wrong concept, unlike the fully fine-tuned SD models. → Mohammed I. Radaideh 2026

q2 · i? · design · r2
Qualitative assessment across 300 prompts and 16 checkpoints of the LoRA-tuned Flux.1 model; the article states Flux.1 "failed in all 300 images" and was excluded from the checkpoint-scoring panel. No effect size is printed.
"The qualitative assessment of the images generated by Flux.1 showed that the model is not learning and is using the wrong concept and building on it."

- Commercial text-to-image models produce accurate images for broad nuclear concepts but fail on specialized engineering prompts — related
- Fine-tuning on the 1,000-image nuclear dataset improves image fidelity of SD models, with KID and CMMD decreasing over training steps — related
- Generating multiple images per prompt and re-prompting with word variations did not yield accurate nuclear images for failed concepts — related
- LoRA fine-tuning hyperparameters are not model-agnostic: increasing rank above 64 destroyed LLaMA's feedback generation while Gemma remained robust — related
- Human qualitative assessment shows SDXL significantly outperforms SD-v3.5-Medium after fine-tuning, failing on 84 versus 250 of 300 prompts — related
- The CLIP text-image alignment score failed to capture fine-tuning improvements, contradicting KID, CMMD, and human judgment — related
