How can I make this model run faster? It's working too slow...

import torch
from diffusers import FluxPipeline

pipe = FluxPipeline.from_pretrained("black-forest-labs/FLUX.1-schnell", torch_dtype=torch.bfloat16) # can replace schnell with dev

# to run on low vram GPUs (i.e. between 4 and 32 GB VRAM)
pipe.enable_sequential_cpu_offload()
pipe.vae.enable_slicing()
pipe.vae.enable_tiling()

pipe.to(torch.float16) # casting here instead of in the pipeline constructor because doing so in the constructor loads all models into CPU memory at once

prompt = f"{ai_msg_prompt.content}"
out = pipe(
    prompt=prompt,
    guidance_scale=0.,
    height=1024,
    width=1024,
    num_inference_steps=4,
    max_sequence_length=256,
).images[0]
out.show()
out.save("image.png")
