# Baseline concept training

[Contents](https://huggingface.co/SimpleTuner/Qwen-Image-2.1-LoRA-experiments/blob/main/README.md) · [Next: Training the assistant: v1 and v2](https://huggingface.co/SimpleTuner/Qwen-Image-2.1-LoRA-experiments/blob/main/experiments/training-assistants.md)

At 500 updates, ordinary 512px training produced a recognisable Domokun in the beach scene, with unusual geometry. At 1,000 updates, both original scene prompts returned people and the unrelated fox acquired a large toothed mouth.

| Setting | Value |
| --- | --- |
| Training | Domokun only, 512px, 1,000 updates |
| Learning rate | `1e-4` |
| Assistant | None |

## Prompt and guidance comparison

With the character noun and CFG 4, the final checkpoint produces Domokun-like imagery with facial-placement and shape errors; the fox is conventional.

512px output · 40 inference steps · true two-pass CFG 4 · CUDA-generator seeds shown below · Details-fixed VAE (madebyollin) · full-frame decoding. Seed: 123.

### Final checkpoint, CFG 4, seed 123

## Limitations

Prompt wording and CFG change together in the second comparison, so their individual effects remain unresolved.
