+# Flux.2 Klein 9B — RTX 3070 best baseline
+
+This is the current best tested Flux.2 Klein text-to-image workflow for the 8 GB RTX 3070.
+
+## Settings
+
+- Model: `flux-2-klein-9b-fp8mixed.safetensors`
+- Text encoder: `qwen_3_8b_fp8mixed.safetensors` (`flux2`)
+- VAE: `flux2-vae.safetensors`
+- Resolution: 1920×1080
+- Sampler: `euler_cfg_pp`
+- Steps: 6
+- CFG: 1.3
+- Seed: `20260920`
+- Measured generation time: approximately 78 seconds
+
+The seed and prompt are intentionally fixed so future sampler, scheduler, step, CFG, LoRA, and second-pass experiments can be compared consistently.
+
+## Optional second pass
+
+SeedVR2 3B FP8 produced a successful 2560×1440 output from this baseline. A 3840×2160 attempt ran out of the GPU's 8 GB VRAM. The SeedVR2 pass is therefore an optional export step, not part of the fast generation baseline.
