FLUX.2 [dev] Turbo LoRA

FLUX.2 [dev] Turbo is a distilled LoRA adapter for FLUX.2 [dev] that enables high-quality image generation in just 8 inference steps.

Example Text-to-Image

Key Features

⚡ 8-step inference — 6x faster than the base model's typical 50 steps
🎨 Quality preserved — Matches or surpasses the original FLUX.2 [dev] quality
🔌 LoRA adapter — Lightweight, easy to integrate with existing FLUX.2 workflows
🖼️ Multiple modes — Supports both text-to-image and image editing

Hosted API Endpoints

FLUX.2 [dev] Turbo is available through fal.ai hosted endpoints:

ComfyUI

ComfyUI-compatible weights are available in the comfy/ directory, converted by ByteZSzn.

Usage

python

import torch
from diffusers import Flux2Pipeline

# Pre-shifted custom sigmas for 8-step turbo inference
TURBO_SIGMAS = [1.0, 0.6509, 0.4374, 0.2932, 0.1893, 0.1108, 0.0495, 0.00031]

pipe = Flux2Pipeline.from_pretrained(
    "black-forest-labs/FLUX.2-dev", 
    torch_dtype=torch.bfloat16
).to("cuda")

pipe.load_lora_weights(
    "fal/FLUX.2-dev-Turbo", 
    weight_name="flux.2-turbo-lora.safetensors"
)

prompt = "Industrial product shot of a chrome turbocharger with glowing hot exhaust manifold, engraved text 'FLUX.2 [dev] Turbo by fal' on the compressor housing and 'fal' on the turbine wheel, gradient heat glow from orange to electric blue , studio lighting with dramatic shadows, shallow depth of field, engineering blueprint pattern in background."
