+# Flux.2 Klein — photorealistic character conversion
+
+Converts a stylized character reference into a photorealistic full-body editorial photograph while preserving identity, pose, clothing, accessories, and framing.
+
+## 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
+
+Files:
+
+- `workflow.json` — API-format prompt.
+- `ui-workflow.json` — native ComfyUI web-editor workflow.
