# 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.
