Dev-bf16

So, Im having a hard time figuring out how I can use the Dev-bf16 transformers.. I tried just plugging them in with available comfy workflow but realized that those sigmas/steps are for the comfy-int8 files and likely wont work. Does anyone have any ideas on how to put together a functioning workflow for the dev-bf16 transformers???

Hi,
The official workflows are all designed to work with the distilled version (bf16 OR int8). The dev version will give you better details and versatility but it requires 30 steps of denoising. you can apply the distilled lora on top of it (plug a load lora node after the diffusion model loader) to get faster generation with 8 steps.

Can you share more details about what you're trying to achieve by using the dev-bf16 transformers file?

Hey, thanks @adamoster for gettin back at me.. So, the distilled models definitely swap with the int8 on the current workflows. But I was trying to figure out how to set up the the full-dev model that uses the steps rather than the sampler with manual sigmas.. I remember I had one for ltx-2, but I can't remember for the life of me how that workflow was setup.. It was definitely a more complicated node graph, or at least the one I remember.

Oh yeah, also I am just testing quality/performance among all the versions.

Sorry but i dont understand why you mention his inquiry validating the 30 steps and following that up with plug a distill on it and run 8 steps, when he specifically doesn't want that?

I myself do all my in and outpainting solely through the prompt using a blank canvas that has a variety of things cropped/pasted in on it as a starting reference. l also like to do multi Quadrant scenes within a scene and stuff like that. The wacky stuff i like to mess around with can really push a model and 8 steps on the first pass that it blazes through is just a wall in that sense.

Only tried 2.5 once now but i reckon i'll get some good stuff out of it after messing with it. I already saw a vast improvement in how it merges different things when i get it to merge and in overal motions/interactions. I reckon great things will come out of this after it matures a bit.

Thank you
