> "The most consistent cinematic portrait results I've ever gotten from FLUX."

This is a clean, battle-tested ComfyUI workflow built around the KREA FLUX2 Dev model

(fp8_scaled) โ€” designed from the ground up for photorealistic, cinematic portrait

generation at 1024ร—1024. No CFG hacks. No LoRA stacking required. Just pure FLUX power.

โœ… Uses BasicGuider โ€” FLUX's native CFG-free guidance (no distortion, no oversaturation)

โœ… SamplerCustomAdvanced pipeline โ€” full control over noise, sigmas & sampler

โœ… fp8 e4m3fn precision โ€” runs on 8GB+ VRAM, no quality loss

โœ… Dual CLIP (clip_l + t5xxl) โ€” maximum prompt adherence

โœ… Euler sampler + Simple scheduler @ 20 steps โ€” fast, sharp, consistent

โœ… Randomized seed by default โ€” infinite variation, zero repetition

๐Ÿ“Œ Tips for your own prompts:

- Lead with the shot type: "close-up portrait", "cinematic headshot", "golden hour photo"

- Add lighting: "soft box lighting", "rembrandt lighting", "neon backlight"

- Add lens feel: "85mm f/1.4", "shallow depth of field", "bokeh background"

- Keep it under 120 tokens โ€” FLUX's T5 encoder handles detail natively

Q: Can I add a LoRA?

A: Yes! Add a LoRALoader node between UNETLoader and BasicGuider. Portrait LoRAs work great.

Q: Can I change resolution?

A: Yes, edit the EmptyLatentImage node. Keep total pixels near 1024ร—1024 (โ‰ˆ1MP).

Q: Why no negative prompt?

A: FLUX with BasicGuider is CFG-free โ€” negative prompts don't apply. FLUX just works.

Q: My images look washed out?

A: Make sure you're using flux2-vae.safetensors. The wrong VAE kills colors.
