Timesteps different from the original BFL's implementation?

[dkenw]

Implementation in XLabs' x-flux:

x-flux/src/flux/xflux_pipeline.py

Lines 284 to 288 in ac4e04b

	timesteps = get_schedule(
	num_steps,
	(width // 8) * (height // 8) // (16 * 16),
	shift=True,
	)

For an image of 1024x1024, the image_seq_len passed to get_schedule is set to 64.

Implementation in BFL's flux:

https://github.com/black-forest-labs/flux/blob/87f6fff727a377ea1c378af692afb41ae84cbe04/src/flux/cli.py#L197

timesteps = get_schedule(opts.num_steps, inp["img"].shape[1], shift=(name != "flux-schnell"))

For an image of 1024x1024, the image_seq_len passed to get_schedule is set to 4096. This seems to be more correct in theory. So, is that a bug in your codebase?
