# Flux.2 Klein — photorealistic character conversion

Converts any supplied reference image into a photorealistic image of the same subject. The prompt is intentionally generic: identity, pose, clothing, accessories, colors, proportions, composition, and framing are inferred from the reference image rather than hard-coded.

## Tested baseline

- Reference input: `character_reference.png`
- Model: `flux-2-klein-9b-fp8mixed.safetensors`
- Text encoder: `qwen_3_8b_fp8mixed.safetensors` (`flux2`)
- VAE: `full_encoder_small_decoder.safetensors`
- Sampler: Euler
- Steps: 4
- CFG: 1.0
- Seed: `20260921`
- Measured runtime: approximately 89 seconds on the RTX 3070
